Aizu
Aizu (Japanese: 会津) is the old name of part of the modern-day Japanese prefecture of Fukushima, formerly a part of Mutsu province.
The eponymous Aizu clan (会津藩; -han), daimyo of the region, with their seat at Aizu Wakamatsu Castle. They had traditionally acted as the bodyguards of the shogun in the feudal Japan of the Edo period. During the Boshin War, Aizu continued to resist even after Shogun Tokugawa Yoshinobu's surrender. The Byakkotai ("White Tiger Company") was a group of young samurai who fought to the death. They were finally defeated in September 1868.
The Aizu clan also had close ties to the Shinsengumi.
