Shimazu clan
In 1185, Shimazu Tadahisa (died August 1, 1227) was the founder of the Shimazu clan. As a close retainer of Minamoto no Yoritomo, the founder of the Kamakura shogunate, he was appointed as "jitō" (land steward) of Shimazu Estate in 1185, from which he took the clan name. The Shimazu clan occupied the positions of "shugo" (military governor) of Satsuma, Ōsumi and Hyūga Provinces.
