Shimazu Hisayasu was the eldest son of Shimazu Yoshihiro. Since his uncle, Shimazu Yoshihisa, had no heir, he adopted Hisayasu to be his heir. After the Shimazu clan submitted to the authority of Toyotomi Hideyoshi in 1587, Hideyoshi granted Morokata district in Hyûga province to Hisayasu as his fief, but then also took Hisayasu to Kyoto as a hostage. There, he was married to Yoshihisa's daughter Shimazu Kameju.

Hisayasu then led Shimazu forces in the Odawara Campaign of 1590. He accompanied his father in Hideyoshi's first invasion of Korea but fell ill and died in 1593 in Geoje.
