In the post–Meiji Restoration cadastral reform of July 22, 1878, the area became part of Kitatama District in Kanagawa Prefecture. Haiji, Nakagami, and Sotoyatsu villages were created on April 1, 1889, with the establishment of the modern municipalities system. The entire district was transferred to the control of Tokyo Metropolis on April 1, 1893. The latter two villages merged on January 1, 1928, to form Shōwa Village.
