Nabeshima Naomasa

was the 10th and final daimyō of Saga Domain in Hizen Province, Kyūshū, Japan. His honorary title was Hizen-no-Kami, and he was occasionally referred to as “Prince Hizen” in western accounts during the Bakumatsu period. Biography Naomasa was born the 17th son of Nabeshima Narinao, the 9th daimyō of Saga Domain. His mother was a daughter of Ikeda Harumichi. His wife was the 18th daughter of shōgun Tokugawa Ienari, and one of his concubines was the 19th daughter of Tokugawa Narimasa. On the retirement of his father in 1830, Naomasa was appointed 10th daimyō of Saga at the age of 17. In celebration of his new role and to reinforce the close relations between Saga domain and the shogunate, his father-in-law Shōgun Tokugawa Ienari allowed him the use of one character from his name. Thus, "Narimasa" was written (斉正) until the end of the Edo period.
