Tokugawa Tsunayoshi (徳川 綱吉, February 23, 1646 – February 19, 1709) was the fifth shōgun of the Tokugawa dynasty of Japan. He was the younger brother of Tokugawa Ietsuna, thus making him the son of Tokugawa Iemitsu, the grandson of Tokugawa Hidetada, and the great-grandson of Tokugawa Ieyasu. Tsunayoshi is known for instituting animal protection laws, particularly for dogs. This earned him the nickname of "the dog shōgun". He had a dog named Takemaru.
