ABOUT
About Sanjo City
The present Sanjo City was created in 2005, when the former Sanjo City merged with Sakae Town and Shitada Village. Known as a town of metalworking craftsmanship that began with the making of Japanese nails in the Edo period, it forms the Kenou (central Niigata) area together with Tsubame City. The Sanjo Building of the city office is in Asahimachi.
