Surrender of Nanbu Clan

Date: October 29, 1868 • Location: Tatsuno, Japan

The Nanbu clan of Honshu surrendered to Japanese imperial forces during the Boshin War.

The Nanbu clan was a Japanese samurai clan who ruled most of northeastern Honshū in the Tōhoku region of Japan for over 700 years, from the Kamakura period through the Meiji Restoration of 1868. The Nanbu claimed descent from the Seiwa Genji of Kai Province and were thus related to the Takeda clan. The clan moved its seat from Kai to Mutsu Province in the early Muromachi period, and were confirmed as daimyō of Morioka Domain under the Edo-period Tokugawa shogunate. The domain was in constant conflict with neighboring Hirosaki Domain, whose ruling Tsugaru clan were once Nanbu retainers.
