Tokugawa Tsunayoshi
was a Japanese "daimyō" of the mid-Edo period, who ruled the Sekiyado Domain. Starting from relatively humble origins, he first became the karō of the Tatebayashi Domain, before following his lord Tokugawa Tsunayoshi to Edo upon Tsunayoshi's selection to be 5th "shōgun". In the Tokugawa shogunate, he served as Tsunayoshi's personal aide.
