The bars I've been to haven't carded me at all. But the only club I went was pretty strict. What's more, guys age requirement was 23 and up. Girls is 20. My brother is 22 and was pretty upset about this. I just let him use my passport and I went in 5 mins after with my California ID
BTW, the club is Club Alife in Roppongi. The club itself was very nice, but the music was not the best in my opinion. Really hardcore techno and really old outdated hip hop tracks every once in a while.
Lots of people recommended me to go to Club Ageha (
[ ageHa ])
Supposed to be the biggest club in Japan. I tried to go but their popular events sell out pretty quick. Hopefully I get to experience this club before I leave.
One thing I didn't like about clubbing in Japan is that there's no hooking up in the club. Strictly prohibited... WHACK!
Everything else, was a lot of fun!
Hope this helped a little.
