Doi

The Doi were a Kōno branch at Minami-Doi in Iyo. In 1333 Doi Michimasu rose for Emperor Go-Daigo and took Fuchū Castle.

Michimasu and Tokunō Michitsuna followed Nitta Yoshisada for the Southern Court. In 1336 Michimasu headed toward Echizen, where Shiba Takatsune killed him in the snowy mountains. Michitsuna died at Kanegasaki in 1337. Elsewhere in Iyo, Doi Kiyoyoshi held Ōmori Castle in the sixteenth century; his lands were confirmed in 1587, and he later retired.
