Shimazu Tadatsune (島津 忠恒, November 27, 1576 – April 7, 1638) was a tozama daimyō of Satsuma, the first to hold it as a formal fief (han) under the Tokugawa shogunate, and the first Japanese to rule over the Ryūkyū Kingdom.[1] As lord of Satsuma, he was among the most powerful lords in Japan at the time, and formally submitted to Tokugawa Ieyasu in 1602, to prove his loyalty, being rewarded as a result with the name Matsudaira Iehisa; Matsudaira being a branch family of the Tokugawa, and "Ie" of "Iehisa" being taken from "Ieyasu", this was a great honor. As of 1603, his holdings amounted to 605,000 koku.
