The Tokugawa Gosanke (徳川御三家, "the Three Houses of the Tokugawa"), also called simply Gosanke (御三家, "the Noble Three Houses"), or even Sanke (三家, "the three houses"), were the most noble three branches of the Tokugawa clan of Japan: Owari House of Tokugawa, Kii House of Tokugawa, and Mito House of Tokugawa, 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.[1] 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.


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).[1] From this allocation of fiefs came the names of the houses they founded, officially called Owari House of Tokugawa (尾張徳川家, Owari Tokugawa-ke), Kii House of Tokugawa (紀伊徳川家, Kii Tokugawa-ke), and Mito House of Tokugawa (水戸徳川家, Mito Tokugawa-ke)). 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.[2] 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 House

The senior one was the Owari branch. The first of this line was Tokugawa Yoshinao, 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),[3] 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.[2]

Kii House

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.[3] 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 House

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.[3] Eleven men headed the house, including Tokugawa (Mito) Mitsukuni. The Mito House was not allowed to provide a shōgun, but only his vice.[3] 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.

Other uses of the term

In modern Japanese, the word "gosanke" is used to refer to "the strongest three" or "the most famous three" in various contexts. For example, the Imperial Hotel, Hotel Okura, and Hotel New Otani Tokyo are often referred to as one of the three great hotels (御三家, gosanke) of Tokyo. The Otani Hotel was built in the Kioi district of Tokyo, where the Tokyo residence of the Kii House was located.
