Happening bars are basically what swinger clubs are called in Tokyo. There are a lot of them. They are all different but they share some features. In some bars they can get busy in the bar itself too.
It all depends. The swinger clubs are surprising in that a lot of them are more open to the idea. In some they only take people who can speak at least a little Japanese. Others take people even if they speak no Japanese at all as long as everything else is in order. Not only that but a lot of the happening bar swinger clubs in Tokyo actually accept single guys. In Tokyo some places will let single guys in any day of the week. The bad thing about the single guy acceptance policy is that some happening bars can look like sausage factories.
It might not even be normally true. They were usually empty or balanced pretty well between ladies and guys. Bliss Out is one of the most famous happening bars in Tokyo. They accept single guys and foreigners. Anyway, Bliss Out is in Kabukicho. You have to be a member to get into Bliss Out, but becoming a member is as easy as pie. Membership costs Yen for a single guy. Inside Bliss Out has a bar with a lounge. Downstairs is a huge blacked out basement with a big play room and a smaller play room.
There are peeping booths all around the playrooms so people can see in to check out the action. Bliss Out gets pretty busy some nights. You see Japanese and foreign chicks. There are more foreign guys than chicks though.
People are cool and easy to talk to. Other nights you go and it looks pretty dead. Olive 21 is another happening bar in Tokyo. It gets at least as busy as Bliss Out. It can be a real party atmosphere though. Some of the chicks are really into non-Japanese dudes and some of the Japanese guys who bring their girls seem to get off on seeing a foreigner pound them out.
