Japan - specially Tokyo, has one the most thrilling night life in the world. Every fetish in your imagination is present (even some out of your imagination). Thousands of night clubs are available; it is just a question of finding the one with your favorite show.
Of course, female fight is a popular fetish in Japan as you might already have noticed due to the huge number of outlets offering women combat videos. The one below is typical: it is announced as an "amateur" night (the girls are masked) who will fight on a oil mat. There is fight on the stage but it happens only for a fraction of the time. The main target is to display oiled genitalia (not censored for a change) pretty close to the club guests.
