thumb|Yotsuya Station thumb|right|The former 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.

==Geography== Yotsuya is located in the southeastern part of Shinjuku. Prior to 1943, when Tokyo was still a city, Yotsuya was one of its wards and had definite boundaries, but it is less clearly defined today. Yotsuya is generally defined as coinciding with the jurisdiction of the Shinjuku City Yotsuya Branch Office and the Yotsuya Police Station, which includes most of Shinjuku east of Meiji-dōri and south of Yasukuni-dōri. To the east lies the neighborhoods of Banchō in Chiyoda.
