Mimasaka Tomochika (美作朝親)

Tomochika MIMASAKA (date of birth and death unknown) was a samurai (warrior) and gokenin (shogunal retainer) in the early Kamakura period. It is said that he followed Murakami-Genji (Minamoto clan) lineage, and there is a theory stating that he belonged to Seiwa-Genji (Minamoto clan) lineage. His go (pen name) was Mimasaka Kurodo and Mimasaka Sakon Daifu. His child was Ariyasu HONGO.

In the twelfth month of 1209, an incident occured in which he had a dispute with TACHIBANA no Kiminari, a gokenin (shogunal retainer) who was staying at an lodging directly opposite his own, over his wife; this dispute threatened to escalate into a duel, but the issue was resolved with the help of a mediator, Tokifusa HOJO who was sent by order of the Seii taishogun (literally, the "great general who subdues the barbarians") MINAMOTO no Sanetomo. He visited Tsurugaoka Hachiman-gu Shrine as an escort for Sanetomo in 1212, and his name appeared as one of number 2 in the guard of Gakumonjo established in February 1213.

He was assigned to Jito (manager and lord of manor) in Hongo, Oi-gun, Wakasa Province after the Jokyu war. His descendents were named the Hongo clan and continued as gokenin (shogunal retainers) in Kyoto in the Kamakura period.
