Thanks mdchachi.
Deathmatch in hell sounds good and the kind of place I would like to go to.
As to Kabukichō, I had likened it to the tourist strips in southern European holiday resort. I never go anywhere near them when I had went to holiday in Europe simply because it is likely to have trouble in them. As garish as Kabukichō looks from what I saw, I like the Blade Runner/neon-noir vibe to it and I think it would be cool to sit in a few bars in that area to soak up the atmosphere.
Anyway, if I do go to Japan, I am not going to spend much time in the bars and clubs there. It's going to take a lot to organise the trip and given the travel time, I want to actually remember being over there and doing things rather than the sore heads in the morning
