The Yonekura clan, former retainers of the Takeda clan of Kai Province, pledged allegiance to Tokugawa Ieyasu after the Takeda were destroyed by Oda Nobunaga, and subsequently served as "hatamoto" in the Tokugawa shogunate after the Battle of Sekigahara in 1603. (1637–1699) was favored by "Shōgun" Tokugawa Tsunayoshi, rising rapidly through the ranks until he reached the post of "wakadoshiyori" in 1696.
