Ōida

The Ōida were a branch of the Satomi based at Ōida in Echigo Province. In 1333 Ōida Tsunetaka and his son Ujitsune joined Nitta Yoshisada in the attack on Kamakura.

After Yoshisada's death, Ujitsune protected his son Yoshimune and fought in Shinano and the Hokuriku region. The family later served the Uesugi, but in 1590 Ōida Kagekuni was ordered to commit suicide; a relative continued the family name as a retainer of Yonezawa.
