Frenz Frenzy calls itself a 'rainbow haven' and it means that literally: the whole place is awash in colour (including the front door, thankfully, because otherwise it would be impossible to find). Run by long-time expat Sari-chan, this is a welcoming first port of call for gay and lesbian travellers. There's no cover and drinks start at ¥500.
It's on the ground floor of a building with other bars, set back from the road.
