Fussa (24 Kaikan Shinjuku)

24 Kaikan is a chain of men's saunas (manga/capsule hybrid facilities) in Japan with locations that are widely understood to be frequented by gay men, particularly the Shinjuku branch. The Shinjuku location has appeared in gay travel resources for Tokyo as a known cruising-oriented sauna. Facilities typically include private rooms, communal baths, and rest areas. Editors should verify the specific Shinjuku branch is still operating under this name, as the 24 Kaikan chain has restructured some locations.
