After Shiga Yoshisato, the Shiga clan, along with the Ōtomo clan, returned to Bungo Province during the Mongol invasion in 1274, and both expanded their power in Kyushu. The Ōtomo clan became an influential Shugo Daimyo family in northern Kyushu, further becoming Sengoku Daimyo during the Sengoku period. At its zenith, the Ōtomo clan ruled Buzen, Bungo, Chikugo, Hizen, Higo, and Chikuzen Provinces, as well as half of Hyūga and Iyo Provinces.
