You will struggle with the Japanese. Basically they can earn more on the game in Japan than they could in the UK. Also the punters are less demanding than their Western colleagues. For example, OW is meant to be the norm. In Bangkok around Nana, Soi Cowboy etc they have special 'J' bars were the western man is not welcome. Thais like to work the J bars because of the 'three fours': 4 inch, 4 minute, 4,000 baht.
