History

In 1634, during the Edo period, as the outer moat of the Edo Castle was built, a number of temples and shrines moved to the Yotsuya area on the western edge of Shinjuku. In 1698, Naitō Shinjuku had developed as a new (shin) station (shuku or juku) on the Kōshū Kaidō, one of the major highways of that era. Naitō was a daimyo whose mansion stood in the area; his land is now a public park, the Shinjuku Gyoen.
