While there are many gay and lesbian establishments in Tokyo (concentrated mostly in Shinjuku's Ni-chome district), the gay community in Japan is not a vocal one, and in any case, information in English is hard to come by. A useful website for gay club listings is www.utopia-asia.com/tokyobars.htm. Otherwise, the best bet for getting up to speed on the current Tokyo gay and lesbian scene is to head to Ni-chome and stop by one of the establishments.
