Obama Domain
During the Bakumatsu period, Obama Domain initially supported the Tokugawa shogunate. In 1865, the domain executed Mito rebellion leader Takeda Kōunsai and 353 of his followers and nominally participated in the Battle of Toba–Fushimi of the Boshin War. However, seeing that the shogunate was doomed, Sakai Tadaaki came out of retirement to seize control of the domain from his adopted son and defected to the imperial cause. Consequently, he was appointed imperial governor of Wakasa by the new Meiji government until the abolition of the han system in 1871.
