clubs in tokyo or osaka

i was just wondering if their are an good metal clubs in tokyo or osaka? or if there are many pub/clubs that have metal bands playing live.
thanks for any help

i reckon you'll have more luck finding live metal gigs than metal clubs. Tokyo has hundreds of live venues.
I would reckon best bet is hitting the small record stores in shibuya and hunting down flyers or do a web search for a site called (i think) tokyo gig guide.
