Thermae-Yu Shinjuku
テルマー湯 新宿店
Does Thermae-Yu Shinjuku allow tattoos? Yes, covered
Tattoos are allowed, but the rule depends on your sex and where you live. Japanese men and long-term residents are refused.
The facility's own rules page sets it out. Overseas visitors show a passport or air ticket (arrival within 90 days) and bathe wearing one facility-issued seal, ¥330. Women of any nationality may enter with fashion tattoos, with a purchased seal for anything over 30 cm × 30 cm (11.8 × 11.8 in). Japanese men and long-term residents are refused regardless of size, and a seal doesn't help.
The bath
A day spa in Kabukicho, open 24 hours, with one real spring: the open-air bath, Kamiyo no Yu, filled with water trucked from the Kamiyo spring in Izu, heated, diluted and circulated. Around it are a carbonated bath at 38 to 39°C, a silk-bubble bath, a lying jet bath, a 17°C cold plunge and two saunas a side, with a mist sauna for men and a mud-pack and salt sauna for women. The baths close for cleaning 3 to 6 a.m. The entry fee buys up to 18 hours between 6 a.m. and midnight with the bath tax, room wear and towels; midnight to 6 a.m. in the building adds a late-night charge, with no going out and coming back. No rooms: people sleep in the lounges.

- Read the tattoo rule before you go. It turns on sex and residency, not size.

Best for: visiting tourists staying in Shinjuku who read the policy carefully first
Listed because it does admit many tattooed visitors, but the terms are unusual enough that it's worth reading the official page before you go.
