Shinjuku City

Shinjuku City occupies 18.22 square kilometres near the centre of Tokyo's special wards. Its territory includes Yotsuya, Ushigome and Okubo, extending beyond the neighbourhood around Shinjuku Station. Plateaus and lowlands divide these districts. The ward's name comes from Naito-Shinjuku, an Edo-period stopping place on the road towards Kofu. Kabukicho houses its city office. [Shinjuku City's outline](https://www.foreign.city.shinjuku.lg.jp/en/introduction/) describes these boundaries and origins.

The municipal authority provides resident registration, health, welfare and education services. It also administers local lodging rules alongside national law. Japan's private-lodging system allows special wards to handle notifications, supervise operators and impose local restrictions through ordinances. Those powers make the ward government a direct point of contact for hosts and residents with lodging complaints. [Japan Tourism Agency guidance](https://www.mlit.go.jp/kankocho/minpaku/overview/minpaku/law1_en.html) explains the division of responsibility.
