Marquis Hachisuka Mochiaki was the 14th and final daimyo of Tokushima Domain, Awa Province, and the 2nd President of the House of Peers in Meiji period Japan.
Hachisuka was born at the Hachisuka domain residence in Edo, as the eldest son of the 13th daimyo Hachisuka Narihiro . Hachisuka Narihiro was the 22nd child of Shogun Tokugawa Ienari, and was adopted into the Hachisuka clan as the 12th daimyo, Hachisuka Narimasa was childless. Thus, Mochiaki was the grandson of Tokugawa Ienari. However, when his father suddenly died in 1868 and he became heir, Japan was already in the midst of the Boshin War leading to the Meiji Restoration. Quick to see the direction in which the wind was blowing, he pledged loyalty to the Imperial forces, and led his troops against Tokugawa partisans in Mutsu Province. His forces were armed with western rifles and accompanied by British military advisors, giving him a much greater strength than their small numbers might have indicated.
