Ōgo

The Ōgo were a warrior family based around Ōgo on the southern slopes of Mount Akagi in Kōzuke Province. In 1350 they fought for Ashikaga Takauji against his brother Tadayoshi's supporters at Kasakake, where they were defeated.

The family later lost its position at Ōgo, while one branch moved to Ushigome in Musashi and served the Later Hōjō. By 1559 an Ōgo family member held land at Ushigome; his descendants took the name Ushigome and later served the Tokugawa.
