8 Oct 2023 update: Bliss Out has suddenly closed. A successor might open, but not announced yet.
Most English-friendly Happening Bar in Tokyo, and as such: high ratio of foreigners (expats/tourists).
Manager is very friendly and well-established in the local kink community.
The former location was closed in 2022 and it has reopened at a new location (also in Shinjuku) at the beginning of 2023: much smaller than the previous location (only one floor, one play area) and serve-yourself drink area.
