Satomi Yoshitoshi

Satomi Yoshitoshi, also called Nitta Yoshitoshi, was a late Heian warrior and the eldest son, born of a concubine, of Nitta Yoshishige, first head of the Nitta clan. He yielded the succession to his legitimate half-brother Yoshikane and founded a branch house, receiving Chikuringō in Nitta-no-shō.

Around 1154 to 1155 he moved to Usui Castle near Satomigō and took the name Satomi. He died before his father and was buried at Kōmyōji.
