Anyone know any good livehouses with open mics?

Anyone know any livehouses with Open Mics that let rock bands play for a couple songs in Japan?

If you know any in Tokyo or Fukuoka, that would be especially great.
If the livehouses have a mostly local Japanese clientele, that would be awesome. (Me and my friends are going on a trip to Japan, so we kinda wanna play somewhere where it wouldn't like back home)

Thanks!
