During the Ansei era (1854-1860) he returned to Tsuyama; however, the Nakagawa house was ultimately succeeded by his youngest brother Katsutaka, and Issho returned to in Man'en 1 (1860). Two years later, in Bunkyu 2 (1862), he changed "Ikkatsu" to "Issho." Traditionally counted among Ichijo's celebrated "Five Tigers" (Goko), he died in Meiji 9 (1876) at the age of forty-eight.
