Shigemasa was a retainer of Tsutsui Sadatsugu. He fought at Sekigahara (1600) and was given the Shimabara area of Hizen province in 1615 (60,000 koku). He reputedly contemplated an invasion of the Philippines that found tacit support with shôgun Tokugawa Iemitsu but died before any attempt could be made. His son Katsuie would be in large measure responsible for the Shimabara Rebellion of 1637.
