Shiga Yoshisato (å¿Âè³ è½é·) was a Japanese samurai lord of the Kamakura period. He was the founder of the Shiga clan, a branch of the à Âtomo clan. He was also known as Buzen Hachirà Â.
Shiga Yoshisato was born as the eighth son of à Âtomo Yoshinao and Shinmyà Â. Yoshinao was a gokenin of shogun Minamoto no Yoritomo and the founder of the à Âtomo clan, and served as Governor of Buzen and Bungo Provinces, Defense Commissioner of the West and Lieutenant of the Left Division of Inner Palace Guards (Sakon no shà Âgen) under the Kamakura shogunate. Shimyà  was the daughter of Hatakeyama Shigeyoshi, lord of Hatakeyama Manor.
In 1223, his father Yoshinao died at the age of 51 and handed him over the position of governor (jità Â), and the territory, of Kachigazuru, Buzen Province.
In 1240, Yoshisato founded the Shiga clan after Shimyà  handed him over the position of jità  of Shiga, à Âno Manor, Bungo Province.
At the time of his Buddhist refuge, he received the Buddhist name Shinjyaku.
After Shiga Yoshisato, the Shiga clan, along with the à Âtomo clan, returned to Bungo Province during the Mongol invasion in 1274, and both expanded their power in Kyushu. The à Âtomo clan became an influential Shugo Daimyo family in northern Kyushu, further becoming Sengoku Daimyo during the Sengoku period. At its zenith, the à Âtomo clan ruled Buzen, Bungo, Chikugo, Hizen, Higo, and Chikuzen Provinces, as well as half of Hyà «ga and Iyo Provinces.
