Gosanke

The , also called simply , or even , were the most noble three branches of the Tokugawa clan of Japan: Owari, Kii, and Mito, all of which were descended from clan founder Tokugawa Ieyasu's three youngest sons, Yoshinao, Yorinobu, and Yorifusa, and were allowed to provide a shōgun in case of need.Iwanami Nihonshi Jiten, ''Tokugawa Gosanke'', ''Tokugawa Owari-ke'', ''Tokugawa Kii-ke'', and ''Tokugawa Mito-ke'' In the Edo period the term ''gosanke'' could also refer to various other combinations of Tokugawa houses, including (1) the shogunal, Owari and Kii houses and (2) the Owari, Kii, and Suruga houses (all with the court position of ''dainagon'').

Later, ''Gosanke'' were deprived of their role to provide a ''shōgun'' by three other branches that are closer to the shogunal house: the ''Gosankyō''.

Even after the fall of the Tokugawa shogunate and the abolition of the Edo-period system of administrative domains (''han'') the three houses continued to exist in some form, as they do into the 21st century.

History

After he established his shogunate, Ieyasu proceeded to put members of his family in key positions. Ninth son Yoshinao was nominated ''daimyō'' of Nagoya (Owari Province), tenth son Yorinobu ''daimyō'' of Wakayama (Kii Province) and eleventh son Yorifusa ''daimyō'' of Mito (Hitachi Province). From this allocation of fiefs came the names of the houses they founded, officially called , , and ). Ieyasu gave them the right to supply a shōgun in order to ensure the presence of successors to the Tokugawa shogunate in case the main line should become extinct. This occurred twice during the Edo period: when the seventh shōgun died heirless in 1716, and when the thirteenth shōgun died heirless in 1858.

The three houses had the highest rank among the '' shinpan'', the ''daimyōs'' who were relatives of the shōgun. After the Meiji Restoration, under the ''kazoku'' system, the heads of the three houses became marquesses. In 1929 the head of the Mito House was elevated from marquess to duke.

Owari branch

The senior one was the Owari branch, ninth son of Ieyasu. He and his heirs were ''daimyōs'' of the Owari Domain (''Owari Han''), with its headquarters at Nagoya Castle. The fief had a rating of 619,500 ''koku'', a ''koku'' being the quantity of rice necessary to feed one person for a year (about 180 liters),Iwanami Kōjien Japanese Dictionary and was the largest of the three. Before the abolition of the shogunate and of the ''han'' system, the house was headed successively by 17 men. Its seniority notwithstanding, the Owari were the only one not to provide a shōgun.

Kii branch

Second in seniority was Kii or Kishū House. The founder was Tokugawa Yorinobu, the tenth son of Ieyasu. Yorinobu was ''daimyō'' of the Kishū Han with its castle at Wakayama and a rating of 555,000 ''koku''. He entered Wakayama in 1619 when the previous ''daimyō'' was transferred. Fourteen members of the Tokugawa clan headed the fief during the Edo Period. It was the only family to directly produce successors to the shōgun, once in 1716 with Tokugawa Yoshimune and again in 1858 with Tokugawa Iemochi.

The fifth Tokugawa ''daimyō'' of Kii was Yoshimune, who later became shōgun and appointed a relative to head the Kii ''Han''. Yoshimune established three new houses, the ''gosankyō'', installing two sons and a grandson as their heads. The ''gosanke'' provided the model for the ''gosankyō.'' However, while Yoshimune granted lands to the ''gosankyō'', the lands were not consolidated into coherent ''han'', but instead were scattered in various places; the total holdings were also smaller than those of the ''gosanke.'' Eventually, one of the ''gosankyō'' houses, the Hitotsubashi house, produced two shoguns, once in 1787 (Tokugawa Ienari) and again in 1866 (Tokugawa Yoshinobu).

Mito branch

Third in seniority among the ''Gosanke'' was the Mito branch. Its founder was Tokugawa Yorifusa, the eleventh son of Ieyasu. Their fief was the Mito Han in Hitachi Province, with its castle in Mito and lands rated initially at 250,000 ''koku'', and later (1710) at 350,000. Eleven men headed the house, including Tokugawa (Mito) Mitsukuni. The Mito House was not allowed to provide a shōgun, but only his vice. It did manage however to produce one when one of its sons, Tokugawa Yoshinobu, was adopted by the Hitotsubashi (one of the Kii House's three ''Gosankyō'') in 1848 and became the last shōgun as a member of that house.
