Tanaka Domain
Nishio Tadateru was the eldest son of Nishio Tadanaga, daimyō of Tsuchiura Domain, but was born in Suruga Province. In 1620, at the age of seven, he became head of the Nishio clan and daimyō of Tsuchura on his father's death. In 1621, he attended to "Shōgun" Tokugawa Hidetada during his pilgrimage to the Nikkō Tōshō-gū, and were permitted to expand the size of his castle. On February 11, 1649, his holdings were increased in size by an additional 5,000 "koku" when he was transferred to Tanaka Domain in Suruga.
