Ogasawara Nagafusa

Ogasawara Nagafusa (1213–1276) was a mid-Kamakura warrior and gokenin, ancestor of the Awa Ogasawara line. The second son of Ogasawara Nagatsune, he took over as shugo of Awa Province after the Jōkyū War of 1221, when his elder brother Nagatada, appointed to the post, chose to return to Shinano.

In 1267, on the shogunate's orders, he destroyed Taira no Moritaka and was rewarded with over twenty-six thousand chō of land in the Mima and Miyoshi districts. He ruled Awa from Iwakura Castle, and his descendants held the Awa shugo post until the fall of Kamakura.
