The Kōriki clan (高力氏 Kōriki-shi) was a fudai samurai clan which briefly came to prominence during the Sengoku and early Edo period Japan. Kōriki Kiyonaga (1530-1608) was a hereditary retainer of the Tokugawa clan, who served Tokugawa Ieyasu as bugyō of Sunpu and was made daimyō of Iwatsuki Domain (20,000 koku) in Musashi Province in 1590 after the Tokugawa were transferred to the Kantō region by Toyotomi Hideyoshi.
His son, Kōriki Tadafusa (1583-1655) distinguished himself in combat during the Battle of Sekigahara and the Siege of Osaka and was transferred to Hamamatsu Domain (35,000 koku) in Tōtōmi Province in 1619, and subsequently to Shimabara Domain (40,00 koku) in Hizen Province. However, his son Kōriki Takanaga (1604-1676) was dispossessed for bad administration and exiled to Sendai in Mutsu Province in 1668. The clan subsequently sunk into obscurity as a 3,000 koku hatamoto clan based initially in Dewa Province, and later in Shimōsa Province to the end of the Edo period.
