124-565: SS Lapland was a steam ocean liner built in Ireland for the Belgian Red Star Line , as Red Star's flagship , similar in appearance to the fellow liners SS Samland , SS Gothland and SS Poland , but far larger. She was a half sister to White Star Line 's " Big Four ." They were similar in many ways, such as the island bridge, 4 masts, 2 funnels. But Lapland had a less luxurious interior. Her ownership passed to

248-458: A "major driver of the first wave of trade globalization (1870–1913)" and contributor to "an increase in international trade that was unprecedented in human history". Steamships were preceded by smaller vessels, called steamboats , conceived in the first half of the 18th century, with the first working steamboat and paddle steamer , the Pyroscaphe , from 1783. Once the technology of steam

372-571: A center of Japanese culture. Following the Meiji Restoration , Osaka greatly expanded in size and underwent rapid industrialization. In 1889, Osaka was officially established as a municipality. The construction boom accelerated population growth throughout the following decades, and by the 1900s, Osaka was the industrial hub in the Meiji and Taishō periods. Osaka made noted contributions to redevelopment, urban planning and zoning standards in

496-610: A certain depth, however when the depth of the ship changed from added weight it further submerged the paddle wheel causing a substantial decrease in performance. Within a few decades of the development of the river and canal steamboat, the first steamships began to cross the Atlantic Ocean . The first sea-going steamboat was Richard Wright's first steamboat Experiment , an ex-French lugger ; she steamed from Leeds to Yarmouth in July 1813. The first iron steamship to go to sea

620-443: A day when travelling at 13 knots (24 km/h; 15 mph). Her maiden outward voyage to Melbourne took 42 days, with one coaling stop, carrying 4,000 tons of cargo. Other similar ships were rapidly brought into service over the next few years. By 1885 the usual boiler pressure was 150 pounds per square inch (1,000 kPa) and virtually all ocean-going steamships being built were ordered with triple expansion engines. Within

744-566: A demonstration project for the potential use of nuclear energy. Thousands of Liberty Ships (powered by steam piston engines) and Victory Ships (powered by steam turbine engines) were built in World War II. A few of these survive as floating museums and sail occasionally: SS  Jeremiah O'Brien , SS  John W. Brown , SS  American Victory , SS  Lane Victory , and SS  Red Oak Victory . A steam turbine ship can be either direct propulsion (the turbines, equipped with

868-430: A few further experiments until SS  Aberdeen  (1881) went into service on the route from Britain to Australia. Her triple expansion engine was designed by Dr A C Kirk, the engineer who had developed the machinery for Propontis . The difference was the use of two double ended Scotch type steel boilers, running at 125 pounds per square inch (860 kPa). These boilers had patent corrugated furnaces that overcame

992-551: A few years, new installations were running at 200 pounds per square inch (1,400 kPa). The tramp steamers that operated at the end of the 1880s could sail at 9 knots (17 km/h; 10 mph) with a fuel consumption of 0.5 ounces (14 g) of coal per ton mile travelled. This level of efficiency meant that steamships could now operate as the primary method of maritime transport in the vast majority of commercial situations. In 1890, steamers constituted 57% of world's tonnage, and by World War I their share raised to 93%. By 1870

1116-502: A four-cylinder quadruple-expansion engine , and her service speed was 17 knots (31 km/h). On 10 April 1909 Lapland began her maiden voyage from Antwerp via Dover to New York City under the Belgian flag. Lapland was one of a fleet of Red Star liners that between them provided weekly sailings on the route. In April 1912 White Star Line chartered Lapland to repatriate 172 surviving members of Titanic ' s crew to

1240-473: A given distance, but fewer firemen were needed to fuel the boilers, so crew costs and their accommodation space were reduced. Agamemnon was able to sail from London to China with a coaling stop at Mauritius on the outward and return journey, with a time on passage substantially less than the competing sailing vessels. Holt had already ordered two sister ships to Agamemnon by the time she had returned from her first trip to China in 1866, operating these ships in

1364-510: A head wind, most notably against the southwest monsoon when returning with a cargo of new tea. Though the auxiliary steamers persisted in competing in far eastern trade for a few years (and it was Erl King that carried the first cargo of tea through the Suez Canal ), they soon moved on to other routes. What was needed was a big improvement in fuel efficiency. While the boilers for steam engines on land were allowed to run at high pressures,

1488-452: A large subterranean network of shopping arcades. Kita and nearby Nakanoshima contain a prominent portion of the city's skyscrapers and are often featured in photographs of Osaka's skyline. Minami, though meaning "south", is essentially in Chūō Ward ( 中央区 , Chūō-ku ) and geographically central within the city. Well known districts here include Namba and Shinsaibashi shopping areas,

1612-551: A lively and important port. Daimyōs (feudal lords) received most of their income in the form of rice . Merchants in Osaka thus began to organize storehouses where they would store a daimyō ' s rice in exchange for a fee, trading it for either coin or a form of receipt; essentially a precursor to paper money . Many if not all of these rice brokers also made loans, and would actually become quite wealthy and powerful. Osaka merchants coalesced their shops around Dōjima , where

1736-403: A long bush of soft metal was fitted in the after end of the stern tube. SS  Great Eastern had this arrangement fail on her first transatlantic voyage, with very large amounts of uneven wear. The problem was solved with a lignum vitae water-lubricated bearing, patented in 1858. This became standard practice and is in use today. Since the motive power of screw propulsion is delivered along

1860-502: A metropolis like Tokyo met with stiff opposition in some municipalities, particularly the highly populated Sakai . He then fell back on a project that included the suppression of the 24 wards of Osaka, thus dividing the city into 5 new special districts with a status similar to that of the 23 Special wards of Tokyo . It was introduced by former mayor Tōru Hashimoto , leader of the reform party Osaka Restoration Association which he founded. The referendum of May 17, 2015 called in Osaka for

1984-570: A new style in the construction of Shinto shrines, called Sumiyoshi-zukuri . The maritime panorama enjoyed from the shrine gardens inspired several artists, and nowadays the representations of that type of landscape are called Sumiyoshi drawings . Towards the end of the Yayoi period the Uemachi plateau-peninsula expanded further, transforming the Kawachi Lagoon into a lake (河内湖) connected to

2108-502: A number of inventions such as the screw propeller , the compound engine , and the triple-expansion engine made trans-oceanic shipping on a large scale economically viable. In 1870 the White Star Line ’s RMS  Oceanic set a new standard for ocean travel by having its first-class cabins amidships, with the added amenity of large portholes, electricity and running water. The size of ocean liners increased from 1880 to meet

2232-458: A particularly compact compound engine and taken great care with the hull design, producing a light, strong, easily driven hull. The efficiency of Holt's package of boiler pressure, compound engine and hull design gave a ship that could steam at 10 knots on 20 long tons of coal a day. This fuel consumption was a saving from between 23 and 14 long tons a day, compared to other contemporary steamers. Not only did less coal need to be carried to travel

2356-457: A peasant insurrection in response to the city's unwillingness to support the many poor and suffering families in the area. Approximately one-quarter of the city was razed before shogunal officials put down the rebellion, after which Ōshio killed himself. Osaka was opened to foreign trade by the government of the Bakufu at the same time as Hyogo Town (modern Kobe ) on January 1, 1868, just before

2480-404: A predominantly industrial center. The modern municipality was established in 1889 by government ordinance , with an initial area of 15 square kilometres (6 sq mi), overlapping today's Chuo and Nishi wards. Later, the city went through three major expansions to reach its current size of 223 square kilometres (86 sq mi). Osaka was the industrial center most clearly defined in

2604-558: A prominent bay area which serves as its main port as well as a tourist destination with attractions such as Kyocera Dome , Universal Studios Japan and the Tempozan Harbor Village . Higashiosaka is zoned as a separate city, although the east side of Osaka city proper contains numerous residential neighborhoods including Tsuruhashi KoreaTown, as well as the Osaka Castle Park , Osaka Business Park and

2728-474: A reduction gear, rotate directly the propellers), or turboelectric (the turbines rotate electric generators, which in turn feed electric motors operating the propellers). While steam turbine-driven merchant ships such as the Algol -class cargo ships (1972–1973), ALP Pacesetter-class container ships (1973–1974) and very large crude carriers were built until the 1970s, the use of steam for marine propulsion in

2852-426: A sailing vessel. The steam engine would only be used when conditions were unsuitable for sailing – in light or contrary winds. Some of this type (for instance Erl King ) were built with propellers that could be lifted clear of the water to reduce drag when under sail power alone. These ships struggled to be successful on the route to China, as the standing rigging required when sailing was a handicap when steaming into

2976-449: A second referendum to merge Osaka's 24 wards into 4 semi-autonomous wards was narrowly voted down. There were 692,996 (50.6%) votes against and 675,829 (49.4%) votes supported it. Osaka mayor and Osaka Ishin co-leader Ichiro Matsui said he would resign when his term ends in 2023. On February 27, 2012, three Kansai cities, Kyoto , Osaka, and Kobe , jointly asked Kansai Electric Power Company to break its dependence on nuclear power. In

3100-399: A shaft that is positioned above the waterline, with the cylinders positioned below the shaft. SS  Great Britain used chain drive to transmit power from a paddler's engine to the propeller shaft – the result of a late design change to propeller propulsion. An effective stern tube and associated bearings were required. The stern tube contains the propeller shaft where it passes through

3224-741: Is a designated city in the Kansai region of Honshu in Japan , and one of the three major cities of Japan ( Tokyo -Osaka- Nagoya ). It is the capital of and most populous city in Osaka Prefecture , and the third-most populous city in Japan, following the special wards of Tokyo and Yokohama . With a population of 2.7 million in the 2020 census, it is also the largest component of the Keihanshin Metropolitan Area , which

3348-511: Is abundant, with winter being the driest season, while monthly rainfall peaks in June with the "tsuyu" rainy season, which typically ends in mid to late July. From late July through the end of August, summer's heat and humidity peaks, and rainfall decreases somewhat. Osaka experiences a second rainy period in September and early October, when tropical weather systems, including typhoons, coming from

3472-460: Is an international center of research and development and is represented by several major universities, notably Osaka University , Osaka Metropolitan University , and Kansai University . Famous landmarks in the city include Osaka Castle , Osaka Aquarium Kaiyukan , Dōtonbori , Tsūtenkaku in Shinsekai , Tennōji Park , Abeno Harukas , Sumiyoshi Taisha Grand Shrine , and Shitennō-ji , one of

3596-531: Is located in the humid subtropical climate zone ( Köppen Cfa ), with four distinct seasons. Its winters are generally mild, with January being the coldest month having an average high of 9.7 °C (49 °F). The city rarely sees snowfall during the winter. Spring in Osaka starts off mild, but ends up being hot and humid. It also tends to be Osaka's wettest season, with the tsuyu ( 梅雨 , tsuyu , "plum rain") —the rainy season—occurring between early June and late July. The average starting and ending dates of

3720-523: Is now Osaka, making it the capital of Japan. The city now known as Osaka was at this time referred to as Naniwa, and this name and derivations of it are still in use for districts in central Osaka such as Naniwa ( 浪速 ) and Namba ( 難波 ). Although the capital was moved to Asuka (in Nara Prefecture today) in 655, Naniwa remained a vital connection, by land and sea, between Yamato (modern day Nara Prefecture ), Korea , and China. Naniwa

3844-539: Is the second-largest metropolitan area in Japan and the 10th- largest urban area in the world with more than 19 million inhabitants. Ōsaka was traditionally considered Japan's economic hub. By the Kofun period (300–538) it had developed into an important regional port, and in the 7th and 8th centuries, it served briefly as the imperial capital. Osaka continued to flourish during the Edo period (1603–1867) and became known as

3968-477: Is the current and 104th president since May 2008. The mayor of the city is directly elected by the citizens every four years as well, in accordance with the Local Autonomy Law. Tōru Hashimoto , former governor of Osaka Prefecture is the 19th mayor of Osaka since 2011. The mayor is supported by two vice mayors, currently Akira Morishita and Takashi Kashiwagi, who are appointed by him in accordance with

4092-409: Is the headquarters of Daihatsu , one of Japan's oldest automobile manufacturers. Like its European and American counterparts, Osaka displayed slums, unemployment, and poverty. In Japan it was here that municipal government first introduced a comprehensive system of poverty relief, copied in part from British models. Osaka policymakers stressed the importance of family formation and mutual assistance as

4216-734: The 1st Aero Squadron , the first unit of the United States Army Air Service to reach France. On 24 November 1918 she began her first voyage after the Armistice when she sailed from Liverpool for New York for the White Star Line and on 1 August 1919 started her sixth and last round voyage on this service. On 16 September 1919 she was transferred to the Southampton – New York route under charter to White Star Line. She made three round voyages on this route,

4340-528: The Board of Trade (under the authority of the Merchant Shipping Act 1854 ) would not allow ships to exceed 20 or 25 pounds per square inch (140 or 170 kPa). Compound engines were a known source of improved efficiency – but generally not used at sea due to the low pressures available. Carnatic (1863) , a P&O ship, had a compound engine – and achieved better efficiency than other ships of

4464-458: The Cold War (eg. Russian aircraft carrier Admiral Kuznetsov ), because of needs of high power and speed, although from 1970s they were mostly replaced by gas turbines . Large naval vessels and submarines continue to be operated with steam turbines, using nuclear reactors to boil the water. NS Savannah , was the first nuclear-powered cargo-passenger ship, and was built in the late 1950s as

4588-468: The Dōtonbori canal entertainment area, Nipponbashi Den Den Town, as well as arts and fashion culture-oriented areas such as Amerikamura and Horie. The 300-meter tall Abeno Harukas was the tallest skyscraper in the country from 2014 until 2023. The business districts between Kita and Minami such as Honmachi  [ ja ] and Yodoyabashi  [ ja ] , called Semba ( 船場 ) , house

4712-711: The East Coast to the West Coast of the United States began on 28 February 1849, with the arrival of SS  California in San Francisco Bay . The California left New York Harbor on 6  October 1848, rounded Cape Horn at the tip of South America, and arrived at San Francisco, California, after a four-month and 21-day journey. The first steamship to operate on the Pacific Ocean was

4836-735: The International Navigation Company in 1914 and the UK Leyland Line in 1927. In the First World War she was converted into a troop ship . In 1933 she was sold to Japanese buyers who scrapped her in 1934. Harland and Wolff built Lapland in Belfast, launching her on 27 June 1908 and completing her on 27 March 1909. She was 605.8 ft (184.6 m) long and had a beam of 70.4 ft (21.5 m). She had twin screw propellers , each driven by

4960-594: The Mediterranean and then through the Red Sea . While this worked for passengers and some high value cargo, sail was still the only solution for virtually all trade between China and Western Europe or East Coast America. Most notable of these cargoes was tea , typically carried in clippers . Another partial solution was the Steam Auxiliary Ship – a vessel with a steam engine, but also rigged as

5084-480: The Rice Exchange was established in 1697 and where the world's first futures market would come to exist to sell rice that was not yet harvested. The popular culture of Osaka was closely related to ukiyo-e depictions of life in Edo . By 1780, Osaka had cultivated a vibrant arts culture, as typified by its famous Kabuki and Bunraku theaters. In 1837, Ōshio Heihachirō , a low-ranking samurai , led

5208-690: The UK after they had been detained in the USA for investigations. She also carried 1,927 bags of mail that Titanic had been scheduled to carry. Lapland arrived in England on 28 April, 13 days after Titanic sank. In 1914 she made her last voyage between Antwerp and New York, was transferred to the US-owned International Navigation Company and began sailing between Liverpool and New York. On 29 October 1914 Lapland began

5332-409: The kanji 坂 was abhorred because it "returns to the earth," and then 阪 was used. The kanji 土 (earth) is also similar to the word 士 (knight), and 反 means against, so 坂 can be understood as "samurai rebellion," then 阪 was official name in 1868 after the Meiji Restoration . The older kanji (坂) is still in very limited use, usually only in historical contexts. As an abbreviation,

5456-696: The reciprocating steam engine , and was far easier to control. Diesel engines also required far less supervision and maintenance than steam engines, and as an internal combustion engine it did not need boilers or a water supply, therefore was more space efficient and cheaper to build. The Liberty ships were the last major steamship class equipped with reciprocating engines. The last Victory ships had already been equipped with marine diesels, and diesel engines superseded both steamers and windjammers soon after World War Two. Most steamers were used up to their maximum economical life span, and no commercial ocean-going steamers with reciprocating engines have been built since

5580-476: The 1960s when large-scale prefectural suburbanization began and doubled to six million by the 1990s. The factories were rebuilt and trade revived, the city were developed rapidly it became a major multicultural and financial center in the postwar period between the 1950s and the 1980s , it is known as the " Chicago and Toronto of the Orient". Osaka Prefecture was chosen as the venue for the prestigious Expo '70 ,

5704-401: The 1960s. Most steamships today are powered by steam turbines . After the demonstration by British engineer Charles Parsons of his steam turbine-driven yacht, Turbinia , in 1897, the use of steam turbines for propulsion quickly spread. The Cunard RMS Mauretania , built in 1906 was one of the first ocean liners to use the steam turbine (with a late design change shortly before her keel

5828-645: The 300-meter tall Abeno Harukas opened, which is the tallest skyscraper in Japan surpassing the Yokohama Landmark Tower in Yokohama , until it was surpassed by the 330-meter tall Azabudai Hills Main Tower in Tokyo since 2022. The city's west side is open to Osaka Bay , and is otherwise completely surrounded by more than ten satellite cities, all of them in Osaka Prefecture , with one exception:

5952-539: The Atlantic Ocean on a scheduled liner voyage before she was converted to diesels in 1986. The last major passenger ship built with steam turbines was the Fairsky , launched in 1984, later Atlantic Star , reportedly sold to Turkish shipbreakers in 2013. Most luxury yachts at the end of the 19th and early 20th centuries were steam driven (see luxury yacht ; also Cox & King yachts ). Thomas Assheton Smith

6076-596: The Atlantic, around the southern tip of Africa, and across the Indian Ocean . Before 1866, no steamship could carry enough coal to make this voyage and have enough space left to carry a commercial cargo. A partial solution to this problem was adopted by the Peninsular and Oriental Steam Navigation Company (P&O), using an overland section between Alexandria and Suez , with connecting steamship routes along

6200-471: The Bristol-New York route. The idea of regular scheduled transatlantic service was under discussion by several groups and the rival British and American Steam Navigation Company was established at the same time. Great Western's design sparked controversy from critics that contended that she was too big. The principle that Brunel understood was that the carrying capacity of a hull increases as

6324-550: The Jomon period. In addition to the remains of consumed food, there were arrow heads, stone tools, fishing hooks and crockery with remains from rice processing. It is estimated that the ruins contain 2,000-year-old debris between the Jomon and Yayoi period . The findings of the archeological sites are exhibited in an adjacent building. In the years between the end of the Jōmon period and

6448-527: The Liverpool to New York route. RMS  Titanic was the largest steamship in the world when she sank in 1912; a subsequent major sinking of a steamer was that of the RMS ; Lusitania , as an act of World War I . Launched in 1938, RMS  Queen Elizabeth was the largest passenger steamship ever built. Launched in 1969, Queen Elizabeth 2 (QE2) was the last passenger steamship to cross

6572-714: The Liverpool – New York City crossings under the UK flag while under charter to Cunard Line . In April 1917 she struck a naval mine off the Mersey Bar Lightship , but managed to reach Liverpool. She sailed from Halifax to Liverpool on 29 September 1916 with Canadian troops of the 150th Battalion of the Canadian Expeditionary Force. In June 1917 she was requisitioned and converted into a troop ship. Among her passengers in August 1917 were aviators of

6696-400: The Osaka region in terms of calculation, shrewdness, lack of civic spirit, and the vulgarity of Osaka dialect. Edo writers aspired to samurai culture, and saw themselves as poor but generous, chaste, and public spirited. Edo writers by contrast saw "zeeroku" as obsequious apprentices, stingy, greedy, gluttonous, and lewd. To some degree, Osaka residents are still stigmatized by Tokyo observers in

6820-601: The advent of the Boshin War and the Meiji Restoration . The Kawaguchi foreign settlement , now the Kawaguchi subdistrict, is a legacy of the foreign presence in Osaka. Osaka residents were stereotyped in Edo literature from at least the 18th century. Jippensha Ikku in 1802 depicted Osakans as stingy almost beyond belief. In 1809, the derogatory term "Kamigata zeeroku" was used by Edo residents to characterize inhabitants of

6944-433: The air raid took almost the entire night and destroyed 25 square miles (65 km ) of the city. The U.S. bombed the city again twice in June 1945 and again on August 14, a day before Japan's surrender . In the decades after World War II, the reconstruction plan and the industriousness of its inhabitants ensured Osaka even greater prosperity than it had before the war. Osaka's population regrew to more than three million in

7068-514: The approval of this project saw the narrow victory of no, and consequently Hashimoto announced his withdrawal from politics. A second referendum for a merger into 4 semi-autonomous wards was narrowly voted down by 692,996 (50.6%). According to the Forbes list of The World's Most Expensive Places To Live 2009 , Osaka was the second most expensive in the world after Tokyo . By 2020 it slipped to 5th rank of most expensive cities. On March 7, 2014,

7192-551: The beginning of the Yayoi period, the sediments that were deposited north of the Uemachi peninsula / plateau transformed Kawachi Bay into a lagoon. During the Yayoi period (300 BCE-250 CE), permanent habitation on the plains grew as rice farming became popular. At the beginning of the third century CE the grand shrine of Sumiyoshi-taisha was inaugurated near the harbor, commissioned by consort Empress Jingū . This Shinto shrine structure survived historical events, which inaugurated

7316-482: The best way to combat poverty. This minimized the cost of welfare programs. During World War II , Osaka came under air raids in 1945 by the United States Army Air Forces as part of the air raids on Japan . On March 13, 1945, a total of 329 Boeing B-29 Superfortress heavy bombers took part in the raid against Osaka. According to an American prisoner of war who was held in the city,

7440-971: The city bylaw. Osaka also houses several agencies of the Japanese government. Below is a list of governmental offices housed in Osaka. In July 2012, a joint multi-party bill was submitted to the Diet that would allow for implementation of the Osaka Metropolis plan as pursued by the mayor of Osaka city, the governor of Osaka and their party . If implemented, Osaka City, neighboring Sakai City and possibly other surrounding municipalities would dissolve and be reorganized as four special wards of Osaka prefecture – similar to former Tokyo City 's successor wards within Tokyo prefecture. Special wards are municipal-level administrative units that leave some otherwise municipal administrative responsibilities and revenues to

7564-565: The city of Amagasaki , belonging to Hyōgo Prefecture , in the northwest. The city occupies a larger area (about 13%) than any other city or village within Osaka Prefecture. When the city was established in 1889, it occupied roughly the area known today as the Chuo and Nishi wards, only 15.27 square kilometres (6 sq mi) that would eventually grow into today's 222.30 square kilometres (86 sq mi) via incremental expansions,

SECTION 60

7688-426: The commercial market has declined dramatically due to the development of more efficient diesel engines . One notable exception are LNG carriers which use boil-off gas from the cargo tanks as fuel. However, even there the development of dual-fuel engines has pushed steam turbines into a niche market with about 10% market share in newbuildings in 2013. Lately, there has been some development in hybrid power plants where

7812-436: The competing problems of heat transfer and sufficient strength to deal with the boiler pressure. Aberdeen was a marked success, achieving in trials, at 1,800 indicated horsepower , a fuel consumption of 1.28 pounds (0.58 kg) of coal per indicated horsepower. This was a reduction in fuel consumption of about 60%, compared to a typical steamer built ten years earlier. In service, this translated into less than 40 tons of coal

7936-491: The copula ya instead of da , and the suffix -hen instead of -nai in negative verb forms. The Osaka City Council is the city's local government formed under the Local Autonomy Law . The council has eighty-nine seats, allocated to the twenty-four wards proportional to their population and re-elected by the citizens every four years. The council elects its president and Vice President. Toshifumi Tagaya ( LDP )

8060-435: The cube of its dimensions, while water resistance only increases as the square of its dimensions. This meant that large ships were more fuel efficient, something very important for long voyages across the Atlantic. Great Western was an iron-strapped, wooden, side-wheel paddle steamer, with four masts to hoist the auxiliary sails. The sails were not just to provide auxiliary propulsion, but also were used in rough seas to keep

8184-451: The development of capitalism in Japan. It became known as the " Manchester and Melbourne of the Orient". In 1925, it was the largest and most populous city in Japan and sixth in the world. The rapid industrialization attracted many Asian immigrants (Indians, Chinese, and Koreans), who set up a life apart for themselves. The political system was pluralistic, with a strong emphasis on promoting industrialization and modernization. Literacy

8308-444: The early 1850s. This was superseded at the beginning of the 20th century by floating pad bearing which automatically built up wedges of oil which could withstand bearing pressures of 500 psi or more. Steam-powered ships were named with a prefix designating their propeller configuration i.e. single, twin, triple-screw. Single-screw Steamship SS , Twin-Screw Steamship TSS , Triple-Screw Steamship TrSS . Steam turbine-driven ships had

8432-539: The favorable geological conditions, rich in fresh water and lush vegetation, and because its position was defensible against military attack. The earliest evidence of settlements in the Osaka area are the Morinomiya ruins ( 森ノ宮遺跡 , Morinomiya iseki ) which is located in the central Chuo-ku district. Buried human skeletons and a kaizuka (a mound containing remains), were found as well as shell mounds, oysters, and other interesting archeological discoveries from

8556-514: The first world's fair ever held in an Asian country. Since then, numerous international events have been held in Osaka, including the 1995 APEC Summit . The modern municipality, which when it was established in 1889 occupied an area of just 15 km including the districts of Chūō and Nishi, following three successive expansions has reached an area of 222 km . It was one of the first cities in Japan to obtain designated city status in 1956. The plan to reorganize Osaka and its province into

8680-411: The first screw propeller to an engine at his Birmingham works, an early steam engine , beginning the use of a hydrodynamic screw for propulsion. The development of screw propulsion relied on the following technological innovations. Steam engines had to be designed with the power delivered at the bottom of the machinery, to give direct drive to the propeller shaft . A paddle steamer's engines drive

8804-410: The hub Kyōbashi Station . Osaka contains numerous urban canals and bridges, many of which serve as the namesake for their surrounding neighborhoods. The phrase "808 bridges of Naniwa" was an expression in old Japan used to indicate impressiveness and the "uncountable". Osaka numbered roughly 200 bridges by the Edo period and 1,629 bridges by 1925. As many of the city's canals were gradually filled in,

8928-425: The hull as waves pass beneath it—becomes too great. Iron hulls are far less subject to hogging, so that the potential size of an iron-hulled ship is much greater. In the spring of 1840 Brunel also had the opportunity to inspect SS  Archimedes , the first screw-propelled steamship, completed only a few months before by F. P. Smith's Propeller Steamship Company. Brunel had been looking into methods of improving

9052-429: The hull structure. It should provide an unrestricted delivery of power by the propeller shaft. The combination of hull and stern tube must avoid any flexing that will bend the shaft or cause uneven wear. The inboard end has a stuffing box that prevents water from entering the hull along the tube. Some early stern tubes were made of brass and operated as a water lubricated bearing along the entire length. In other instances

9176-581: The largest of which being a single 126.01-square-kilometre (49 sq mi) expansion in 1925. Osaka's highest point is 37.5 metres (123.0 ft) Tokyo Peil in Tsurumi-ku , and the lowest point is in Nishiyodogawa-ku at −2.2 metres (−7.2 ft) Tokyo Peil. Osaka has a latitude of 34.67 (near the 35th parallel north ), which makes it more southern than Rome (41.90), Madrid (40.41), San Francisco (37.77) and Seoul (37.53). Osaka

9300-402: The last starting on 27 November 1919. Lapland was refitted with passenger accommodation for 389 first, 448 second and 1,200 third class passengers and her tonnage was revised to 18,565  GRT . On 3 January 1920 she resumed service for Red Star Line but under the UK flag when she sailed from Antwerp via Southampton to New York. In 1927 she was transferred to Leyland Line and that April she

9424-588: The modern kanji 阪 han refers to Osaka City or Osaka Prefecture . During the Jōmon period (7,000 BCE), present-day Osaka was mostly submerged, and the Uemachi Plateau ( 上町台地 , Uemachi Daichi ) formed a 12 km long and 2.5 km wide peninsula separating Kawachi Bay from the Seto Inland Sea . It is considered one of the first places where inhabitants of Japan settled, both for

9548-519: The mouth of the Yodo River , which had widened to the south. By the Kofun period , Osaka developed into a hub port connecting the region to the western part of Japan. The port of Naniwa-tsu was established and became the most important in Japan. Trade with other areas of the country and the Asian continent intensified. The large numbers of increasingly larger keyhole-shaped Kofun mounds found in

9672-402: The needs of the human migration to the United States and Australia. RMS  Umbria and her sister ship RMS  Etruria were the last two Cunard liners of the period to be fitted with auxiliary sails. Both ships were built by John Elder & Co. of Glasgow, Scotland, in 1884. They were record breakers by the standards of the time, and were the largest liners then in service, plying

9796-577: The newly formed Blue Funnel Line . His competitors rapidly copied his ideas for their own new ships. The opening of the Suez Canal in 1869 gave a distance saving of about 3,250 nautical miles (6,020 km; 3,740 mi) on the route from China to London. The canal was not a practical option for sailing vessels, as using a tug was difficult and expensive – so this distance saving was not available to them. Steamships immediately made use of this new waterway and found themselves in high demand in China for

9920-501: The number dropped to 872, of which 760 are currently managed by Osaka City. There are currently 24 wards in Osaka: per km Population numbers have been recorded in Osaka since as early as 1873, in the early Meiji era . According to the census in 2005, there were 2,628,811 residents in Osaka, an increase of 30,037 or 1.2% from 2000. There were 1,280,325 households with approximately 2.1 persons per household. The population density

10044-409: The oldest Buddhist temples in Japan. Ōsaka means "large hill" or "large slope". It is unclear when this name gained prominence over Naniwa, but the oldest written evidence for the name dates back to 1496. By the Edo period , 大坂 ( Ōsaka ) and 大阪 ( Ōsaka ) were mixed use, and the writer Hamamatsu Utakuni  [ ja ] , in his book Setsuyo Ochiboshu published in 1808, states that

10168-419: The operating costs of steamships were still too high in certain trades, so sail was the only commercial option in many situations. The compound engine, where steam was expanded twice in two separate cylinders, still had inefficiencies. The solution was the triple expansion engine, in which steam was successively expanded in a high pressure, intermediate pressure and a low pressure cylinder. The theory of this

10292-456: The paddle steamer Beaver , launched in 1836 to service Hudson's Bay Company trading posts between Puget Sound Washington and Alaska . The most testing route for steam was from Britain or the East Coast of the U.S. to the Far East . The distance from either is roughly the same, between 14,000 to 15,000 nautical miles (26,000 to 28,000 km; 16,000 to 17,000 mi), traveling down

10416-453: The performance of Great Britain ' s paddlewheels, and took an immediate interest in the new technology, and Smith, sensing a prestigious new customer for his own company, agreed to lend Archimedes to Brunel for extended tests. Over several months, Smith and Brunel tested a number of different propellers on Archimedes in order to find the most efficient design, a four-bladed model submitted by Smith. When launched in 1843, Great Britain

10540-455: The plains of Osaka are evidence of political-power concentration, leading to the formation of a state. The findings in the neighboring plains, including the mausoleum of Emperor Nintoku was discovered nearby in Sakai testify to the status of imperial city that Osaka had reached. Four of these mounds can be seen in Osaka, in which important members of the nobility are buried. They are located in

10664-795: The port of Savannah, Georgia , US, on 22 May 1819, arriving in Liverpool , England, on 20 June 1819; her steam engine having been in use for part of the time on 18 days (estimates vary from 8 to 80 hours). A claimant to the title of the first ship to make the transatlantic trip substantially under steam power is the British-built Dutch-owned Curaçao , a wooden 438-ton vessel built in Dover and powered by two 50 hp engines, which crossed from Hellevoetsluis , near Rotterdam on 26 April 1827 to Paramaribo , Surinam on 24 May, spending 11 days under steam on

10788-414: The port of Naniwa-tsu increased in such a way that huge warehouses were built to stow material arriving and departing. The Kojiki records that during 390–430 CE, there was an imperial palace located at Osumi, in what is present day Higashiyodogawa ward , but it may have been a secondary imperial residence rather than a capital. In 645, Emperor Kōtoku built his Naniwa Nagara-Toyosaki Palace in what

10912-561: The postwar period, and the city developed rapidly as one of the major financial centers in the Keihanshin Metropolitan Area. Osaka is a major financial center of Japan, and it is recognized as one of the most multicultural and cosmopolitan cities in Japan. The city is home to the Osaka Exchange as well as the headquarters of multinational electronics corporations such as Panasonic and Sharp . Osaka

11036-457: The prefectural administration. In October 2018, the city of Osaka officially ended its sister city relationship with San Francisco in the United States after the latter permitted a monument memorializing "comfort women" to remain on a city-owned property, circulating in the process a 10-page, 3,800-word letter in English addressed to San Francisco mayor London Breed . On November 1, 2020,

11160-464: The prefix TS . In the UK the prefix RMS for Royal Mail Steamship overruled the screw configuration prefix. The first steamship credited with crossing the Atlantic Ocean between North America and Europe was the American ship SS  Savannah , though she was actually a hybrid between a steamship and a sailing ship, with the first half of the journey making use of the steam engine. Savannah left

11284-427: The rainy season are June 7 and July 21 respectively. Summers are very hot and humid. In August, the hottest month, the average daily high temperature reaches 33.7 °C (93 °F), while average nighttime low temperatures typically hover around 25.8 °C (78 °F). Fall in Osaka sees a cooling trend, with the early part of the season resembling summer while the latter part of fall resembles winter. Precipitation

11408-457: The regional headquarters of many large-scale banks and corporations. The Midōsuji boulevard runs through Semba and connects Kita and Minami. Further south of Minami are neighborhoods such as Shinsekai (with its Tsūtenkaku tower), Tennoji and Abeno (with Tennoji Zoo , Shitennō-ji and Abeno Harukas ), and the Kamagasaki slums, the largest slum in Japan. The city's west side is

11532-539: The revolutionary SS  Great Britain , also built by Brunel, became the first iron-hulled screw-driven ship to cross the Atlantic. SS Great Britain was the first ship to combine these two innovations. After the initial success of its first liner, SS  Great Western of 1838, the Great Western Steamship Company assembled the same engineering team that had collaborated so successfully before. This time however, Brunel, whose reputation

11656-431: The same way today, especially in terms of gluttony, evidenced in the phrase, "Residents of Osaka devour their food until they collapse" ( 大阪は食倒れ , "Ōsaka wa kuidaore" ) . With the enormous changes that characterized the country after the Meiji Restoration (1868), and the relocation of the capital from Kyoto to Tokyo , Osaka entered a period of decline. From being the capital of the economy and finance, it became

11780-478: The shaft, a thrust bearing is needed to transfer that load to the hull without excessive friction. SS  Great Britain had a 2 ft diameter gunmetal plate on the forward end of the shaft which bore against a steel plate attached to the engine beds. Water at 200 psi was injected between these two surfaces to lubricate and separate them. This arrangement was not sufficient for higher engine powers and oil lubricated "collar" thrust bearings became standard from

11904-537: The ship on an even keel and ensure that both paddle wheels remained in the water, driving the ship in a straight line. The hull was built of oak by traditional methods. She was the largest steamship for one year, until the British and American's British Queen went into service. Built at the shipyard of Patterson & Mercer in Bristol, Great Western was launched on 19 July 1837 and then sailed to London, where she

12028-513: The south or southwest are possible. Osaka's sprawling cityscape has been described as "only surpassed by Tokyo as a showcase of the Japanese urban phenomenon". Central Osaka is roughly divided into downtown and uptown areas known as Kita ( キタ , "north") and Minami ( ミナミ , "south") . Kita is home to the Umeda district and its immediate surrounding neighborhoods, a major business and retail hub that plays host to Osaka Station City and

12152-526: The southern districts of the city and date back to the 5th century. A group of megalithic tombs called Mozu Tombs are located in Sakai , Osaka Prefecture. Important works of the Kofun period is the excavation that diverted the course of the Yamato River , whose floods caused extensive damage, and the construction of important roads in the direction of Sakai and Nara . Maritime traffic connected to

12276-521: The start of the 1870 tea season. The steamships were able to obtain a much higher rate of freight than sailing ships and the insurance premium for the cargo was less. So successful were the steamers using the Suez Canal that, in 1871, 45 were built in Clyde shipyards alone for Far Eastern trade. Throughout the 1870s, compound-engined steamships and sailing vessels coexisted in an economic equilibrium:

12400-720: The steam turbine is used together with gas engines. As of August 2017 the newest class of Steam Turbine ships are the Seri Camellia -class LNG carriers built by Hyundai Heavy Industries (HHI) starting in 2016 and comprising five units. Nuclear powered ships are basically steam turbine vessels. The boiler is heated, not by heat of combustion , but by the heat generated by nuclear reactor. Most atomic-powered ships today are either aircraft carriers or submarines . Osaka Osaka ( Japanese : 大阪市 , Hepburn : Ōsaka-shi , pronounced [oːsakaɕi] ; commonly just 大阪 , Ōsaka [oːsaka] )

12524-557: The surrender of the monks and subsequent razing of the temple. Toyotomi Hideyoshi constructed Osaka Castle in its place in 1583. Osaka Castle played a pivotal role in the Siege of Osaka (1614–1615). Osaka was long considered Japan's primary economic center, with a large percentage of the population belonging to the merchant class (see Four divisions of society ). Over the course of the Edo period (1603–1867), Osaka grew into one of Japan's major cities and returned to its ancient role as

12648-612: The time. Her boilers ran at 26 pounds per square inch (180 kPa) but relied on a substantial amount of superheat . Alfred Holt , who had entered marine engineering and ship management after an apprenticeship in railway engineering, experimented with boiler pressures of 60 pounds per square inch (410 kPa) in Cleator . Holt was able to persuade the Board of Trade to allow these boiler pressures and, in partnership with his brother Phillip launched Agamemnon in 1865. Holt had designed

12772-422: The two largest groups being Korean (60,110) and Chinese (39,551) 2021 years. Ikuno , with its Tsuruhashi district, is the home to one of the largest population of Korean residents in Japan, with 20,397 registered Zainichi Koreans . The commonly spoken dialect of this area is Osaka-ben , a typical sub-dialect of Kansai-ben . Of the many other particularities that characterize Osaka-ben, examples include using

12896-404: The voyage was actually made under sail. The first ship to make the transatlantic trip substantially under steam power may have been the British-built Dutch-owned Curaçao , a wooden 438-ton vessel built in Dover and powered by two 50 hp engines, which crossed from Hellevoetsluis , near Rotterdam on 26 April 1827 to Paramaribo , Surinam on 24 May, spending 11 days under steam on

13020-479: The way out and more on the return. Another claimant is the Canadian ship SS  Royal William in 1833. The British side-wheel paddle steamer SS  Great Western was the first steamship purpose-built for regularly scheduled trans-Atlantic crossings, starting in 1838. In 1836 Isambard Kingdom Brunel and a group of Bristol investors formed the Great Western Steamship Company to build a line of steamships for

13144-504: The way out and more on the return. Another claimant is the Canadian ship SS  Royal William in 1833. The first steamship purpose-built for regularly scheduled trans-Atlantic crossings was the British side-wheel paddle steamer SS  Great Western built by Isambard Kingdom Brunel in 1838, which inaugurated the era of the trans-Atlantic ocean liner . SS  Archimedes , built in Britain in 1839 by Francis Pettit Smith ,

13268-448: Was 11,836 persons per km . The Great Kantō earthquake caused a mass migration to Osaka between 1920 and 1930, and the city became Japan's largest city in 1930 with 2,453,573 people, outnumbering even Tokyo, which had a population of 2,070,913. The population peaked at 3,252,340 in 1940, and had a post-war peak of 3,156,222 in 1965, but has declined since, as the residents moved out to the suburbs. There were 144,123 registered foreigners,

13392-559: Was an English aristocrat who forwarded the design of the steam yacht in conjunction with the Scottish marine engineer Robert Napier . By World War II , steamers still constituted 73% of world's tonnage, and similar percentage remained in early 1950s. The decline of the steamship began soon thereafter. Many had been lost in the war, and marine diesel engines had finally matured as an economical and viable alternative to steam power. The diesel engine had far better thermal efficiency than

13516-471: Was at its height, came to assert overall control over design of the ship—a state of affairs that would have far-reaching consequences for the company. Construction was carried out in a specially adapted dry dock in Bristol , England. Brunel was given a chance to inspect John Laird 's 213-foot (65 m) (English) channel packet ship Rainbow —the largest iron- hulled ship then in service—in 1838, and

13640-483: Was by far the largest vessel afloat. Brunel's last major project, SS  Great Eastern , was built in 1854–1857 with the intent of linking Great Britain with India, via the Cape of Good Hope , without any coaling stops. This ship was arguably more revolutionary than her predecessors. She was one of the first ships to be built with a double hull with watertight compartments and was the first liner to have four funnels. She

13764-543: Was declared the capital again in 744 by order of Emperor Shōmu , and remained so until 745, when the Imperial Court moved back to Heijō-kyō (now Nara ). By the end of the Nara period, Naniwa's seaport roles had been gradually taken over by neighboring areas, but it remained a lively center of river, channel, and land transportation between Heian-kyō (Kyoto today) and other destinations. Sumiyoshi Taisha Grand Shrine

13888-402: Was established in the 1850s by John Elder , but it was clear that triple expansion engines needed steam at, by the standards of the day, very high pressures. The existing boiler technology could not deliver this. Wrought iron could not provide the strength for the higher pressures. Steel became available in larger quantities in the 1870s, but the quality was variable. The overall design of boilers

14012-452: Was fitted with two side-lever steam engines from the firm of Maudslay, Sons & Field , producing 750 indicated horsepower between them. The ship proved satisfactory in service and initiated the transatlantic route, acting as a model for all following Atlantic paddle-steamers. The Cunard Line 's RMS  Britannia began her first regular passenger and cargo service by a steamship in 1840, sailing from Liverpool to Boston. In 1845

14136-408: Was founded by Tamomi no Sukune in 211 CE. Shitennō-ji was first built in 593 CE and the oldest Buddhist temple in Japan. In 1496, Jōdo Shinshū Buddhists established their headquarters in the heavily fortified Ishiyama Hongan-ji , located directly on the site of the old Naniwa Imperial Palace. Oda Nobunaga began a decade-long siege campaign on the temple in 1570 which ultimately resulted in

14260-419: Was high and the educational system expanded rapidly, producing a middle class with a taste for literature and a willingness to support the arts. In 1927, General Motors operated a factory called Osaka Assembly until 1941, manufacturing Chevrolet , Cadillac , Pontiac , Oldsmobile , and Buick vehicles, operated and staffed by Japanese workers and managers. In the nearby city of Ikeda in Osaka Prefecture

14384-563: Was improved in the early 1860s, with the Scotch-type boilers – but at that date these still ran at the lower pressures that were then current. The first ship fitted with triple expansion engines was Propontis (launched in 1874). She was fitted with boilers that operated at 150 pounds per square inch (1,000 kPa) – but these had technical problems and had to be replaced with ones that ran at 90 pounds per square inch (620 kPa). This substantially degraded performance. There were

14508-405: Was laid down) and was soon followed by all subsequent liners. Most larger warships of the world's navies were propelled by steam turbines burning bunker fuel in both World Wars, apart from obsolete ships with reciprocating machines from the turn of the century, and rare cases of usage of diesel engines in larger warships. Steam turbines burning fuel remained in warship construction until the end of

14632-486: Was mastered at this level, steam engines were mounted on larger, and eventually, ocean-going vessels. Becoming reliable, and propelled by screw rather than paddlewheels, the technology changed the design of ships for faster, more economic propulsion. Paddlewheels as the main motive source became standard on these early vessels. It was an effective means of propulsion under ideal conditions but otherwise had serious drawbacks. The paddle-wheel performed best when it operated at

14756-623: Was refitted to carry cabin, tourist and third class passengers. On 29 April 1932 she started her last voyage between Antwerp, Southampton, Le Havre and New York. In 1932 and 1933 she was used on short cruises from London to the Mediterranean . Between June and September 1933 she carried 5,000 cruise passengers. In October 1933 was sold to Japanese buyers for scrap. She was broken up in Osaka , starting on 29 January 1934. Steamship As steamships were less dependent on wind patterns, new trade routes opened up. The steamship has been described as

14880-416: Was soon converted to iron-hulled technology. He scrapped his plans to build a wooden ship and persuaded the company directors to build an iron-hulled ship. Iron's advantages included being much cheaper than wood, not being subject to dry rot or woodworm , and its much greater structural strength. The practical limit on the length of a wooden-hulled ship is about 300 feet, after which hogging —the flexing of

15004-660: Was the 116-ton Aaron Manby , built in 1821 by Aaron Manby at the Horseley Ironworks , and became the first iron-built vessel to put to sea when she crossed the English Channel in 1822, arriving in Paris on 22 June. She carried passengers and freight to Paris in 1822 at an average speed of 8 knots (9 mph, 14 km/h). The American ship SS  Savannah first crossed the Atlantic Ocean arriving in Liverpool, England, on June 20, 1819, although most of

15128-456: Was the biggest liner throughout the rest of the 19th century with a gross tonnage of almost 20,000 tons and had a passenger-carrying capacity of thousands. The ship was ahead of her time and went through a turbulent history, never being put to her intended use. The first transatlantic steamer built of steel was SS  Buenos Ayrean , built by Allan Line Royal Mail Steamers and entering service in 1879. The first regular steamship service from

15252-399: Was the change from the paddle-wheel to the screw-propeller as the mechanism of propulsion. These steamships quickly became more popular, because the propeller's efficiency was consistent regardless of the depth at which it operated. Being smaller in size and mass and being completely submerged, it was also far less prone to damage. James Watt of Scotland is widely given credit for applying

15376-577: Was the world's first screw propeller -driven steamship for open water seagoing. She had considerable influence on ship development, encouraging the adoption of screw propulsion by the Royal Navy , in addition to her influence on commercial vessels. The first screw-driven propeller steamship introduced in America was on a ship built by Thomas Clyde in 1844 and many more ships and routes followed. The key innovation that made ocean-going steamers viable
