Shimazu Yoshihisa

Shimazu Yoshihisa (島津義久^?, February 9, 1533 – March 5, 1611) was a daimyō of Satsuma Province and the eldest son of Shimazu Takahisa. His mother was a daughter of Iriki'in Shigesato (入来院重聡), Sesshō (雪窓). Shimazu Yoshihiro and Shimazu Toshihisa are his brothers.

His childhood name was Torajumaru (虎寿丸) but went by the name of Matasaburō (又三郎). On his genpuku, he took the name of Tadayoshi(忠良) but after receiving a kanji from the shogun Ashikaga Yoshiteru, changed to Yoshitatsu (義辰). He later changed his name to Yoshihisa. He married his own aunt and after her death, married his relative, a daughter of Tanegashima Tokitaka.

In 1566, he succeeded as the head of Shimazu clan after his father to become the sixteenth leader. Working together with his brother Yoshihiro, Toshihisa, and Shimazu Iehisa, he launched a campaign to unify Kyūshū. Starting in 1572 with the win against Itō clan at the battle of Kizaki, Yoshihisa would win victories after victories. In 1578, he defeated the Ōtomo clan at the battle of Mimigawa, in 1583 against Ryūzōji clan, and on 1584 against the Aso clan. By the middle of the 1580s, the Shimazu clan controlled most of Kyūshū with the exception of Ōtomo's domain and a unification was not far into the future.
