A fuedal Japanese clan founded by Kuniuji Imagawa . After the death of Yoshimoto at the battle of Okehazama in 1560, many Imagawa officers defected to other clans. Within a decade the clan had lost all of its land holdings to the Tokugawa and Takeda clans. The Imagawa subsequently became the master of ceremonies for the Tokugawa.
