Ogenki desu ka? This is an old issue. Japanese like Chinese are not so able to adopt to the rest of the world in terms of language and lifestyle, but the Japanese Way is slicker whereas the Chinese often bend over backwards towards the filthy gaijin without even knowing it wwwwwww.
Part of the problem lies in their xenophobia, and part of their claims that foreigners are rowdy and unable to understand Japanese customs is also true. The saying that 'in Rome, do as the Romans do' has been lost on them.
And on a side note drifter-kun, it is funny that a Filipino prostitute bar there would only admit Japanese and not even Filipino Residents and visitors to the country?
