Furumiya Castle (Kai)

History

Furumiyajō was built in the Muromachi period by the Tsugane Clan as their fortified residence. It is said that the Tusgane Clan was formed by settlers from the Satake Clan of Saku County in Shinano. Indeed, Furumiyajō is situated along an important route between Kai Province and Saku. In the Sengoku period the Tsugane served the Takeda Clan of Kai, forming the Tsuganeshū, a group of warriors dedicated to protecting the Kai-Shinano border. After the fall of the Takeda and Oda hegemons, the Tsugane joined the Tenshō Jingo rebellion and then fought on the side of Tokugawa Ieyasu as he tried and succeeded in wresting Kai from Hōjō Ujinao.

Visit Notes

Furumiyajō is a fortification site in the Tsugane area of Sudama Township in Hokuto Municipality, Yamanashi Prefecture. The most prominent feature of the ruins of this earthworks fort site is the long segment of karabori (dry moat) to the northwest of Tsugane’s Suwa Shrine. It appears that this was a double moat structure, though now a lane runs through the outer moat segment, obscuring it. The inner moat and dorui (earthen ramparts) are fairly well preserved, though a bit overgrown. The site of Furumiyajō is now that of a preserved school. The old school houses are open to the public, and there is a souvenir shop-bakery-restaurant which serves school meals! I bought a packet of ‘school lunch curry’ and dried persimmons.
