Yotsuya

Yotsuya (四谷, 四ツ谷) is an area in Shinjuku, Tokyo, that previously was a ward (四谷区 Yotsuya-ku) in the now-defunct Tokyo City. In 1947, when the 35 wards of Tokyo were reorganized into 23, it was merged with Ushigome ward of Tokyo City and Yodobashi suburban ward of Tokyo-fu to form the modern Shinjuku ward.
