History

The area of present-day Nishikan-ku was part of ancient Echigo Province. The town of Sone and the village of Iwamuro were established on April 1, 1889 within Nakakanbara District, Niigata with the establishment of the municipalities system. The town of Maki was created on April 10, 1891 by the merger of 14 hamlets, and expanded on January 1, 1955 by annexing five neighbouring villages. The town of Nishikawa was founded on January 1, 1955 by the merger of Sone with the village of Masugata. The city of Niigata annexed the towns of Maki and Masugata and the villages of Iwamuro, Katahigashi and Nakanokuchi on March 21, 2005. Niigata became a government-designated city on April 1, 2007 and was divided into wards, with the new Nishikan Ward consisting of these areas.

Education
