APA Hotel Shinjuku-Kabukicho Tower is a business hotel in the middle of Kabukicho, about a 10-minute walk from Shinjuku Station. Rooms are on the small side, and guests can use the free large bath on the 28th floor and the rooftop open-air bath. Check-in is self-service, and luggage can be stored before and after arrival. Room windows do not open, and noise from the Kabukicho main stage and the Toyoko Plaza side can be heard at night, which is uncomfortable for light sleepers.
