The Edo River ( 江戸川 , Edo-gawa ) is a river in the Kantō region of Japan . It splits from the Tone River at the northernmost tip of Noda City in the Sekiyado district, crosses through Nagareyama and Matsudo , and empties into Tokyo Bay at Ichikawa , Chiba Prefecture. The Edo forms the borders between Tokyo , Chiba , and Saitama prefectures. The Edo River is 59.5 kilometres (37.0 mi) long.

64-693: The course of the Edo River was originally the lower course of the Tone River. The Tone was diverted in 1654 by the Tokugawa shogunate to protect the city of Edo from flooding. The Edo was used to connect the north and east of the Kantō region to the capital at Edo, specifically to transport large amounts of cargo from Chōshi and other cities on the Pacific Ocean coast inland to the capital. Before

Provinces are classified into Kinai (in or near the capital, then Kyoto) and seven or eight dō (routes, or circuits ), collectively known as the Gokishichidō . However, dō in this context should not be confused with modern traffic lines such as the Tōkaidō from Tokyo to Kyoto or Kobe . Also, Hokkaidō in this context should not be confused with Hokkaidō Prefecture , although these two overlap geographically. No order has ever been issued explicitly abolishing

192-461: 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 )

256-561: 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

320-523: 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

Simplified names of provinces ( -shū ) are also used, such as Shinshū soba and Kishū dog . Some of the province names are used to indicate distinct parts of the current prefectures along with their cultural and geographical characteristics. In many cases these names are also in use with directional characters, e.g. Hoku-Setsu ( 北摂 ) meaning Northern ( 北 ) Settsu ( 摂津 ) area. The districts are still considered prefectural subdivisions, but following mergers or divisions of

The Provinces of Japan were replaced with the current prefecture system in the Fuhanken sanchisei during the Meiji Restoration from 1868 to 1871, except for Hokkaido , which was divided into provinces from 1869 to 1882. No order has ever been issued explicitly abolishing

704-641: 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

768-768: 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

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

896-528: 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

960-528: 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

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

1152-427: 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

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

Provinces were established in Japan in the late 7th century under the Ritsuryō law system that formed

1344-644: 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

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

1536-417: 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

1600-495: 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

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

1728-459: 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

1792-414: 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

1856-606: 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

1920-484: 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

1984-466: 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

2048-408: 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

2176-417: 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

2240-537: The first central government . Each province was divided into districts ( 郡 , gun ) and grouped into one of the geographic regions or circuits known as the Gokishichidō (Five Home Provinces and Seven Circuits). Provincial borders often changed until the end of the Nara period (710 to 794), but remained unchanged from the Heian period (794 to 1185) until the Edo period (1603 to 1868). The provinces coexisted with

Inland transportation ended in the early 20th century due to the development of an extensive rail cargo network in the Kantō region, but the Edo River remains an important source of water for industrial production as well as drainage for the densely populated areas of metropolitan Tokyo. Tokyo Disneyland

2368-453: The late Muromachi period , however, they were gradually supplanted by the domains of the sengoku daimyō . Under the rule of Toyotomi Hideyoshi during Azuchi–Momoyama period, the provinces were supplemented as primary local administrative units. The local daimyōs ' fiefs were developed. In the Edo period , the fiefs became known as han . Imperial provinces and shogunal domains made up complementary systems. For example, when

2432-583: 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

2496-407: 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

2560-482: 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

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

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

2816-532: The provinces they may be shared among several prefectures (such as the original Adachi District of Musashi , which is now divided between Adachi Ward in Tokyo and Kita-Adachi District in Saitama ). Many of these old provincial districts have been dissolved as their chief towns have been merged into larger cities or towns. See individual prefecture pages for mergers and abolitions of districts. The following list

2880-408: The provinces, but they are considered obsolete as administrative units. The provinces are still used in general conversation, especially in navigation and transportation, and referenced in products and geographical features of the prefectures covering their former territories. The provinces were originally established by the Ritsuryō reforms as both administrative units and geographic regions. From

2944-625: The provinces, but they are considered obsolete. Nevertheless, their names are still widely used in names of natural features, company names, and brands. These province names are considered to be mainly of historical interest. They are also used for the names of items, including family names , most of which were popularized in or after the Edo period . Examples include sanuki udon , iyokan , tosa ken , Chikuzenni , and awa odori . Japan Rail and other railway stations also use them in names to distinguish themselves from similarly named stations in other prefectures, such as Musashi-Kosugi Station . The same

3008-491: 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

3072-566: 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

3136-647: 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

3200-468: 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

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

3328-467: 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

3392-493: The shōgun ordered a daimyō to make a census or to make maps, the work was organized in terms of the boundaries of the provincial kuni . At the Meiji Restoration , the han were legitimized as administrative units by the reform known as the Fuhanken Sanchisei , but they were gradually replaced by prefectures between 1868 and 1871 (urban prefectures were called fu and rural prefectures ken ). Provinces as part of

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

3520-677: 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

3584-459: The system of addresses were not abolished but, on the contrary, augmented. As of 1871, the number of prefectures was 304, while the number of provinces was 68, not including Hokkaidō or the Ryūkyū Islands . The boundaries between the many prefectures were not only very complicated, but also did not match those of the provinces. Prefectures were gradually merged to reduce the number to 37 by 1881;

3648-506: 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

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

3776-484: Was assassinated in 1860 outside the Sakuradamon Gate of Edo Castle ( Sakuradamon incident ). Three to five men titled the wakadoshiyori (若年寄) were next in status below the rōjū. 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

3840-408: 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

3904-870: Was established under the Meiji government , and Tokugawa loyalists continued to fight in the Boshin War until the defeat of the Republic of Ezo at the Battle of Hakodate in June 1869. Following the Sengoku period ("Warring States period"), the central government had been largely re-established by Oda Nobunaga during the Azuchi–Momoyama period . After the Battle of Sekigahara in 1600, central authority fell to Tokugawa Ieyasu. While many daimyos who fought against him were extinguished or had their holdings reduced, Ieyasu

During the earliest years of the Tokugawa shogunate institution, when Tokugawa Hidetada coronated as the second shogun and Ieyasu retired, they formed a dual governments, where Hidetada controlled the official court with the government central located in Edo city, Ieyasu, who now became the Ōgosho (retired shogun), also control his own informal shadow government which called "Sunpu government" with its center at Sunpu Castle . The membership of

These four states are called the Four Western Clans, or Satchotohi for short. Regardless of the political title of the Emperor, the shōguns of the Tokugawa family controlled Japan. The shogunate secured a nominal grant of administration ( 体制 , taisei ) by

4096-481: Was the period between 1853 and 1867, during which Japan ended its isolationist foreign policy called sakoku and modernized from a feudal shogunate to the Meiji government . The 1850s saw growing resentment by the tozama daimyōs and anti-Western sentiment following the arrival of a U.S. Navy fleet under the command of Matthew C. Perry (which led to the forced opening of Japan). The major ideological and political factions during this period were divided into
