69-861: In 1866, the Tokugawa shogunate government established the Yokosuka Seisakusho , a military arsenal and naval base , with the help of foreign engineers , including the French naval architect Léonce Verny . The new facility was intended to produce modern, western-style warships and equipment for the Tokugawa navy. The construction of the arsenal was an important first step for the modernization of Japan's industry. Modern buildings, an aqueduct , foundry , brick factories, and technical schools to train Japanese technicians were established. After

138-417: A beam of 83 feet 6 inches (25.5 m), and a normal draft of 27 feet 6 inches (8.4 m). She displaced 19,372 long tons (19,683  t ) at normal load. The crew ranged from 800 to 940 officers and enlisted men. Satsuma was powered by a pair of vertical triple-expansion steam engines , each driving one propeller, using steam generated by 20 Miyabara water-tube boilers using

207-461: A growing threat to the stability of the shogunate. As Ōgosho ("Cloistered Shōgun "), he influenced the implementation of laws that banned the practice of Christianity. His successors followed suit, compounding upon Ieyasu's laws. The ban of Christianity is often linked with the creation of the Seclusion laws, or Sakoku , in the 1630s. The late Tokugawa shogunate ( Japanese : 幕末 Bakumatsu )

276-660: A licensing "agreement" with Holland's company back in 1905. These pioneering submarines progressively got larger and larger as time went on, climaxing (in size) by the end of the Cold War . In 1909, Japan's first domestically designed and produced battleship , Satsuma , was launched. Yokosuka became one of the main shipyards of the Imperial Japanese Navy in the 20th century, building numerous battleships such as Yamashiro , and aircraft carriers such as Hiryū and Shōkaku . Naval aircraft were designed at

345-450: A mixture of coal and fuel oil . The engines were rated at a total of 17,300 indicated horsepower (12,900  kW ) and designed to reach a top speed of 18.25 knots (33.8 km/h; 21.0 mph). During the ship's sea trials she reached 18.95 knots (35.1 km/h; 21.8 mph) from 18,507 ihp (13,801 kW). Satsuma carried enough coal and oil to give her a range of 9,100 nautical miles (16,900 km; 10,500 mi) at

414-505: A result, the tax revenues collected by the samurai landowners increasingly declined over time. A 2017 study found that peasant rebellions and desertion lowered tax rates and inhibited state growth in the Tokugawa shogunate. By the mid-18th century, both the shogun and daimyos were hampered by financial difficulties, whereas more wealth flowed to the merchant class. Peasant uprisings and samurai discontent became increasingly prevalent. Some reforms were enacted to attend to these issues such as

483-523: A rural population flow to urban areas. By the Genroku period (1688–1704) Japan saw a period of material prosperity and the blossoming of the arts, such as the early development of ukiyo-e by Moronobu . The reign of Tokugawa Yoshimune (1716–1745) saw poor harvests and a fall in tax revenue in the early 1720s, as a result he pushed for the Kyoho reforms to repair the finances of the bakufu as he believed

552-470: A speed of 10 knots (19 km/h; 12 mph). The ship was completed with four 45- caliber 12-inch 41st Year Type guns in two gun turrets, one each fore and aft of the superstructure . They fired 850-pound (386 kg) armor-piercing (AP) shells to a maximum range of 24,000 yd (22,000 m). The intermediate armament consisted of six twin-gun turrets equipped with 45-caliber Type 41 10-inch (254 mm) guns , three turrets on each side of

690-605: The Boshin War and the Meiji Restoration , the new Meiji government took over control of the facility in 1871, renaming it the Yokosuka Zosenjo (Yokosuka Shipyards). The first dry dock was opened in 1871, and is still in operation today. Japan's first domestically produced warship, Saiki , was completed the same year. The Yokosuka Naval District was established at Yokosuka, Kanagawa , in 1884, as

759-582: The Caroline and the Palau Islands in October 1914. Satsuma rejoined the 1st Battleship Squadron in 1915, was refitted at Sasebo Naval Arsenal in 1916 and served with the 1st Squadron for the rest of the war. Sometime during the war, she was fitted with two 12-pounders on high-angle mounts to serve as anti-aircraft guns . The ship was disarmed at Yokosuka Naval Arsenal in 1922 to comply with

828-641: The Edo shogunate ( 江戸幕府 , Edo bakufu ) , was the military government of Japan during the Edo period from 1603 to 1868. The Tokugawa shogunate was established by Tokugawa Ieyasu after victory at the Battle of Sekigahara , ending the civil wars of the Sengoku period following the collapse of the Ashikaga shogunate . Ieyasu became the shōgun , and the Tokugawa clan governed Japan from Edo Castle in

897-768: The Imperial Court in Kyoto to the Tokugawa family. While the Emperor officially had the prerogative of appointing the shōgun and received generous subsidies, he had virtually no say in state affairs. The shogunate issued the Laws for the Imperial and Court Officials ( kinchu narabini kuge shohatto 禁中並公家諸法度) to set out its relationship with the Imperial family and the kuge (imperial court officials), and specified that

966-489: The Kansei reform (1787–1793) by Matsudaira Sadanobu . He bolstered the bakufu's rice stockpiles and mandated daimyos to follow suit. He cut down urban spending, allocated reserves for potential famines, and urged city-dwelling peasants to return to rural areas. By 1800, Japan included five cities with over 100,000 residents, and three among the world's twenty cities that had more than 300,000 inhabitants. Edo likely claimed

1035-551: The Russo-Japanese War . Unlike the previous Katori -class pre-dreadnought battleships , they were the first battleships ordered from Japanese shipyards, although Satsuma used many imported components. They were originally designed with a dozen 12-inch (305 mm) guns, but had to be redesigned because of a shortage of guns in Japan and to reduce costs. The ship had an overall length of 482 feet (146.9 m),

1104-588: The breech was opened and ignited the propellant; the resulting fire killed 16 crewmen and several officers. She was lightly damaged by a typhoon on 22 September 1912. Satsuma was assigned to the 1st Battleship Squadron when World War I began in August 1914. She served as Rear Admiral Tatsuo Matsumura 's flagship in the Second South Seas Squadron as it seized the German possessions of

1173-528: The gundai ( 郡代 ), the daikan ( 代官 ) and the kura bugyō ( 蔵奉行 ), as well as hearing cases involving samurai. The gundai managed Tokugawa domains with incomes greater than 10,000 koku while the daikan managed areas with incomes between 5,000 and 10,000 koku. The shogun directly held lands in various parts of Japan. These were known as shihaisho (支配所); since the Meiji period, the term tenryō ( 天領 , literally "Emperor's land") has become synonymous, because

1242-528: The han and the court in Edo. During their absences from Edo, it was also required that they leave their family as hostages until their return. The hostages and the huge expenditure sankin-kōtai imposed on each han helped to ensure loyalty to the shōgun . By the 1690s, the vast majority of daimyos would be born in Edo, and most would consider it their homes. Some daimyos had little interest in their domains and needed to be begged to return "home". In return for

1311-442: The jisha , kanjō , and machi-bugyō , which respectively oversaw temples and shrines , accounting, and the cities. The jisha-bugyō had the highest status of the three. They oversaw the administration of Buddhist temples ( ji ) and Shinto shrines ( sha ), many of which held fiefs. Also, they heard lawsuits from several land holdings outside the eight Kantō provinces. The appointments normally went to daimyōs ; Ōoka Tadasuke

1380-408: The rōjū to a more distant part of the castle. Some of the most famous soba yōnin were Yanagisawa Yoshiyasu and Tanuma Okitsugu . The ōmetsuke and metsuke were officials who reported to the rōjū and wakadoshiyori . The five ōmetsuke were in charge of monitoring the affairs of the daimyōs , kuge and imperial court. They were in charge of discovering any threat of rebellion. Early in

1449-427: The sankin-kōtai system ensured that daimyōs or their family were always in Edo, observed by the shogun. The shogunate had the power to discard, annex, and transform domains, although they were rarely and carefully exercised after the early years of the shogunate, to prevent daimyōs from banding together. The sankin-kōtai system of alternative residence required each daimyō to reside in alternate years between

1518-410: The shōgun . Under the wakadoshiyori were the metsuke . Some shōguns appointed a soba yōnin . This person acted as a liaison between the shōgun and the rōjū . The soba yōnin increased in importance during the time of the fifth shōgun Tokugawa Tsunayoshi , when a wakadoshiyori, Inaba Masayasu , assassinated Hotta Masatoshi , the tairō . Fearing for his personal safety, Tsunayoshi moved

1587-413: The treaty ports of Nagasaki and Kanagawa (Yokohama). Source: Over the course of the Edo period, influential relatives of the shogun included: Japanese battleship Satsuma Satsuma ( 薩摩 ) was a semi-dreadnought battleship built for the Imperial Japanese Navy (IJN) in the first decade of the 20th century. Lead ship of her class , she was the first battleship built in Japan. She

1656-644: The ōmetsuke evolved into one of passing orders from the shogunate to the daimyōs , and of administering to ceremonies within Edo Castle. They also took on additional responsibilities such as supervising religious affairs and controlling firearms. The metsuke , reporting to the wakadoshiyori , oversaw the affairs of the vassals of the shōgun . They were the police force for the thousands of hatamoto and gokenin who were concentrated in Edo. Individual han had their own metsuke who similarly policed their samurai. The san- bugyō (三奉行 "three administrators") were

1725-467: The "restoration" ( 王政復古 , Ōsei fukko ) of imperial rule. Some loyal retainers of the shogun continued to fight during the Boshin war that followed but were eventually defeated in the notable Battle of Toba–Fushimi . The bakuhan system ( bakuhan taisei 幕藩体制 ) was the feudal political system in the Edo period of Japan. Baku is an abbreviation of bakufu , meaning " military government "—that is,

1794-407: The Edo period, daimyōs such as Yagyū Munefuyu held the office. Soon, however, it fell to hatamoto with rankings of 5,000 koku or more. To give them authority in their dealings with daimyōs , they were often ranked at 10,000 koku and given the title of kami (an ancient title, typically signifying the governor of a province ) such as Bizen-no-kami . As time progressed, the function of

1863-417: The Edo period. They were ranked by size, which was measured as the number of koku of rice that the domain produced each year. One koku was the amount of rice necessary to feed one adult male for one year. The minimum number for a daimyō was ten thousand koku ; the largest, apart from the shōgun , was more than a million koku . The main policies of the shogunate on the daimyos included: Although

1932-495: The Emperor should dedicate to scholarship and poetry. The shogunate also appointed a liaison, the Kyoto Shoshidai ( Shogun's Representative in Kyoto ), to deal with the Emperor, court and nobility. Towards the end of the shogunate, however, after centuries of the Emperor having very little say in state affairs and being secluded in his Kyoto palace , and in the wake of the reigning shōgun , Tokugawa Iemochi , marrying

2001-586: The Sunpu government's cabinet was consisted of trusted vassals of Ieyasu which was not included in Hidetada's cabinet. including William Adams (samurai) and Jan Joosten van Lodensteijn , which Ieyasu entrusted with foreign affairs and diplomacy. The earliest structure of Edo Shogunate organization has Buke Shitsuyaku as the highest rank. the earliest members of this office were Ii Naomasa , Sakakibara Yasumasa , and Honda Tadakatsu . The personal vassals of

2070-459: The Tokugawa clan in the Battle of Sekigahara had their estate reduced substantially. They were often placed in mountainous or far away areas, or placed between most trusted daimyos. Early in the Edo period, the shogunate viewed the tozama as the least likely to be loyal; over time, strategic marriages and the entrenchment of the system made the tozama less likely to rebel. In the end, however, it

2139-414: The Tokugawa shoguns were classified into two groups: By the early 18th century, out of around 22,000 personal vassals, most would have received stipends rather than domains. The rōjū ( 老中 ) were normally the most senior members of the shogunate. Normally, four or five men held the office, and one was on duty for a month at a time on a rotating basis. They supervised the ōmetsuke (who checked on

2277-606: The capital as hostages. In 1616, there was a failed attempt of the invasion of Taiwan by a Shogunate subject named Murayama Tōan . A long period of peace occurred between the Siege of Osaka in 1615 and the Keian Uprising in 1651. This period saw the bakufu prioritise civil administration, while civil society witnessed a surge in trade and industrial activities. Trade under the reign of Ieyasu saw much new wealth created by mining and goods manufacturing, which resulted in

2346-404: The casemates. The barbettes for the main guns were 7–9.5 inches (180–240 mm) thick. The armor of Satsuma ' s main gun turrets had a maximum thickness of nine inches. The deck armor was 2–3 inches (51–76 mm) thick and the conning tower was protected by six inches of armor. Satsuma , named for Satsuma Province , was laid down at Yokosuka Naval Arsenal on 15 May 1905. She

2415-484: The centralization, peace among the daimyos was maintained; unlike in the Sengoku period , daimyos no longer worried about conflicts with one another. In addition, hereditary succession was guaranteed as internal usurpations within domains were not recognized by the shogunate. The Tokugawa clan further ensured loyalty by maintaining a dogmatic insistence on loyalty to the shōgun . Daimyos were classified into three main categories: The tozama daimyos who fought against

2484-466: The country was still nominally organized as imperial provinces . Under the Tokugawa shogunate, Japan experienced rapid economic growth and urbanization, which led to the rise of the merchant class and Ukiyo culture. The Tokugawa shogunate declined during the Bakumatsu period from 1853 and was overthrown by supporters of the Imperial Court in the Meiji Restoration in 1868. The Empire of Japan

2553-408: The country, particularly smaller regions, daimyō, and samurai were more or less identical, since daimyō might be trained as samurai, and samurai might act as local rulers. The largely inflexible nature of this social stratification system unleashed disruptive forces over time. Taxes on the peasantry were set at fixed amounts that did not account for inflation or other changes in monetary value. As

Other bugyō (commissioners) in charge of finances, monasteries and shrines also reported to

2691-417: The eastern city of Edo ( Tokyo ) along with the daimyō lords of the samurai class. The Tokugawa shogunate organized Japanese society under the strict Tokugawa class system and banned most foreigners under the isolationist policies of Sakoku to promote political stability. The Tokugawa shoguns governed Japan in a feudal system, with each daimyō administering a han (feudal domain), although

2760-696: The first of the naval districts responsible for the defense of the Japanese home islands , and the Yokosuka Shipyards was renamed the Yokosuka Naval Arsenal in 1903. Japan had purchased five submarines from the American Electric Boat Company during the Russo-Japanese War of 1904–1905. These Holland Type VII submarines were built by Arthur Leopold Busch as he traveled to Japan during this time. Busch

2829-583: The main vector of trade exchanges, followed by the addition of Dutch, English, and sometimes Spanish ships. From 1603 onward, Japan started to participate actively in foreign trade. In 1615, an embassy and trade mission under Hasekura Tsunenaga was sent across the Pacific to Nueva España (New Spain) on the Japanese-built galleon San Juan Bautista . Until 1635, the Shogun issued numerous permits for

2898-407: The military aristocracy was losing its power against the rich merchants and landowners. Society in the Tokugawa period , unlike in previous shogunates, was supposedly based on the strict class hierarchy originally established by Toyotomi Hideyoshi . The daimyō (lords) were at the top, followed by the warrior-caste of samurai, with the farmers, artisans, and traders ranking below. In some parts of

2967-482: The most powerful han , the hereditary fief of the House of Tokugawa, which also included many gold and silver mines. Towards the end of the shogunate, the Tokugawa clan held around 7 million koku of land (天領 tenryō), including 2.6–2.7 million koku held by direct vassals, out of 30 million in the country. The other 23 million koku were held by other daimyos. The number of han (roughly 270) fluctuated throughout

3036-640: The nearby Yokosuka Naval Air Technical Arsenal . During the Pacific War , the Yokosuka Naval Arsenal was attacked by one bomber during the Doolittle Raid on 18 April 1942 and by a large force of carrier aircraft during the Attack on Yokosuka on 18 July 1945. The facilities were seized by Allied forces at the end of World War II, and on 15 October 1945 the Yokosuka Naval Arsenal was officially abolished. The facilities were used after World War II by

3105-406: The office, and alternated by month. Three Edo machi bugyō have become famous through jidaigeki (period films): Ōoka Tadasuke and Tōyama Kagemoto (Kinshirō) as heroes, and Torii Yōzō ( ja:鳥居耀蔵 ) as a villain. The san-bugyō together sat on a council called the hyōjōsho (評定所). In this capacity, they were responsible for administering the tenryō (the shogun's estates), supervising

3174-456: The offices close to the shōgun , such as soba yōnin  [ ja ] (側用人), Kyoto Shoshidai , and Osaka jōdai . Irregularly, the shōguns appointed a rōjū to the position of tairō (great elder). The office was limited to members of the Ii , Sakai , Doi , and Hotta clans , but Yanagisawa Yoshiyasu was given the status of tairō as well. Among the most famous was Ii Naosuke , who

3243-631: The operation of such craft. Arthur Busch was also the man responsible for building the United States Navy 's first submarine some five or so years before this time for the Holland Torpedo Boat Company . This particular craft was named the USS ; Holland  (SS-1) and was America's first commissioned craft of this type. Two additional Holland-designed submarines were built for Japan by 1906 "under contract" and

3312-532: The pro-imperialist Ishin Shishi ( nationalist patriots ) and the shogunate forces; aside from the dominant two groups, other factions attempted to use the chaos of the Bakumatsu era to seize personal power. An alliance of daimyos and the emperor, succeeded in overthrowing the shogunate, which came to an official end in 1868 with the resignation of the 15th Tokugawa shogun , Tokugawa Yoshinobu , leading to

3381-491: The rōjū. The roju conferred on especially important matters. In the administrative reforms of 1867 ( Keiō Reforms ), the office was eliminated in favor of a bureaucratic system with ministers for the interior, finance, foreign relations, army, and navy. In principle, the requirements for appointment to the office of rōjū were to be a fudai daimyō and to have a fief assessed at 50 000 koku or more. However, there were exceptions to both criteria. Many appointees came from

3450-566: The shogun issued certain laws, such as the buke shohatto on the daimyōs and the rest of the samurai class, each han administered its autonomous system of laws and taxation . The shōgun did not interfere in a han 's governance unless major incompetence (such as large rebellions) was shown, nor were central taxes issued. Instead, each han provided feudal duties, such as maintaining roads and official courier stations, building canals and harbors, providing troops, and relieving famines. Daimyōs were strategically placed to check each other, and

3519-647: The shogun's lands were returned to the emperor. In addition to the territory that Ieyasu held prior to the Battle of Sekigahara, this included lands he gained in that battle and lands gained as a result of the Summer and Winter Sieges of Osaka . Major cities as Nagasaki and Osaka, and mines , including the Sado gold mine , also fell into this category. The gaikoku bugyō were administrators appointed between 1858 and 1868. They were charged with overseeing trade and diplomatic relations with foreign countries, and were based in

3588-468: The shogunate in Edo and the daimyōs with domains throughout Japan. The shōgun and lords were all daimyōs : feudal lords with their own bureaucracies, policies, and territories. Provinces had a degree of sovereignty and were allowed an independent administration of the han in exchange for loyalty to the shōgun , who was responsible for foreign relations, national security, coinage, weights, measures, and transportation. The shōgun also administered

3657-576: The shogunate, yielding a huge profit. Foreign trade was also permitted to the Satsuma and the Tsushima domains . Rice was the main trading product of Japan during this time. Isolationism was the foreign policy of Japan and trade was strictly controlled. Merchants were outsiders to the social hierarchy of Japan and were thought to be greedy. The visits of the Nanban ships from Portugal were at first

3726-467: The shogunate. The han were the domains headed by daimyō . Beginning from Ieyasu's appointment as shogun in 1603, but especially after the Tokugawa victory in Osaka in 1615, various policies were implemented to assert the shogunate's control, which severely curtailed the daimyos' independence. The number of daimyos varied but stabilized at around 270. The bakuhan system split feudal power between

3795-496: The sister of Emperor Kōmei (r. 1846–1867), in 1862, the Imperial Court in Kyoto began to enjoy increased political influence. The Emperor would occasionally be consulted on various policies and the shogun even made a visit to Kyoto to visit the Emperor. Government administration would be formally returned from the shogun to the Emperor during the Meiji Restoration in 1868. Foreign affairs and trade were monopolized by

3864-677: The so-called " red seal ships " destined for the Asian trade. After 1635 and the introduction of seclusion laws ( sakoku ), inbound ships were only allowed from China , Korea , and the Netherlands . The primary source of the shogunate's income was the tax (around 40%) levied on harvests in the Tokugawa clan's personal domains (tenryō). No taxes were levied on domains of daimyos, who instead provided military duty, public works and corvee . The shogunate obtained loans from merchants, which were sometimes seen as forced donations, although commerce

3933-427: The superstructure. Her heavy intermediate armament is why the ship is considered a semi-dreadnought. Satsuma was equipped with a dozen 40-caliber quick-firing (QF) 4.7-inch (120 mm) 41st Year Type guns , mounted in casemates in the sides of the hull. The ship was also equipped with four 40-caliber QF 12-pounder (3-inch (76 mm)) 12-cwt guns and four 28-caliber QF 12-pounder guns . In addition, she

4002-506: The title of the world's most populous city, housing over one million people. Followers of Catholic christians first began appearing in Japan during the 16th century. Oda Nobunaga embraced Christianity and the Western technology that was imported with it, such as the musket. He also saw it as a tool he could use to suppress Buddhist forces. Though Christianity was allowed to grow until the 1610s, Tokugawa Ieyasu soon began to see it as

4071-477: Was launched on 15 November 1906 with Emperor Meiji , the Navy Minister , and other high officials on hand for the ceremony, and completed on 25 March 1910. At the time of her launching, Satsuma had the largest displacement of any battleship in the world. On 5 August 1911, the ship suffered an explosion in one of her 12-inch guns when it failed to fire during gunnery practice. After some time passed,

4140-627: Was a naval architect and shipbuilder who represented the newly organized company Electric Boat Company , now located at the Quincy, Massachusetts shipyard known as the Fore River Ship and Engine Company . These first five submarines became Japan's (IJN) initial entry into the theater of underwater warfare that began nearly the same time as the outbreak of the war. Another representative of Electric Boat, Frank Cable , an electrician working for Isaac L. Rice's company, trained two Japanese crews in

4209-494: Was an exception, though he later became a daimyō . The kanjō-bugyō were next in status. The four holders of this office reported to the rōjū . They were responsible for the finances of the shogunate. The machi-bugyō were the chief city administrators of Edo and other cities. Their roles included mayor, chief of the police (and, later, also of the fire department), and judge in criminal and civil matters not involving samurai. Two (briefly, three) men, normally hatamoto, held

An outgrowth of the early six-man rokuninshū (六人衆, 1633–1649), the office took its name and final form in 1662. Their primary responsibility was management of the affairs of the hatamoto and gokenin , the direct vassals of

4347-408: Was committed to retaining the daimyos and the han (domains) as components under his new shogunate. Daimyos who sided with Ieyasu were rewarded, and some of Ieyasu's former vassals were made daimyos and were located strategically throughout the country. The sankin-kotai policy, in an effort to constrain rebellions by the daimyos, mandated the housing of wives and children of the daimyos in
