I haven't been to O-furo here in Japan, but in Taipei, I've been to a San-wen-nuan (I guess it's borrowing from Sauna), and it's full of middle aged man in huge dragons and tigers tattoo. I was apprehensive about it, and went arond as if I didn't notice them. After O-furo, we were seated at nice sofa and we can order any time of drinks, I ordered a hot Kumquat juice and had a short exchange with my fellow Aniu. Soon a mama-chan came out an inquire us if we want 'special service'. Since I am not a fan of sex shopping, I give her a shake on the head and she went away. We never went back to San-wen-nuan eversince.
