薩長同盟
The Boshin War of the Meiji Restoration, Nabeshima Naotora, the 11th and final "daimyō", supported the Satchō Alliance was called upon to lead Ogi's forces against the Tokugawa remnants at Akita in northern Japan. For his loyalty to Emperor Meiji and efforts in the war, the revenues of Ogi Domain were raised by an additional 5,000 "koku" in August 1869. However, this reward was only nominal, as with the abolition of the han system less than two years later in 1871 Ogi Domain became part of the new Saga Prefecture.
