Minamoto no Nakamasa

Minamoto no Nakamasa (born c. 1050), also called Baba no Nakamasa, was a late-Heian warrior and poet, the second son of Settsu Genji leader Minamoto no Yoritsuna. In 1095 he and his elder brother were named chamberlains to Emperor Horikawa through Shirakawa's favor, and he later served the Shirakawa and Toba courts as kebiishi.

Around 1118–1124 he captured an impostor claiming to be Minamoto no Yoshichika. Fifteen of his poems entered imperial anthologies, and between 1135 and 1142 he passed the family headship to his son Yorimasa.
