Lol I thought he was going to be some sort of pedo the way she is writing the post at first
I'm not sure about Japan probably depends on your looks if your are bringing nothing to the table other than that. I assume it would be easier to do this in Thailand because women in the society are expected to work and MANY thai guys here do exactly this but just sit and smoke cigarettes and drink and hang out with their boys in the rural areas. Not sure about other SEA countires and also I'll add Japan has a pretty militaristic work culture so seriously doubt this will work there. Also forget about blowjobs if you plan on doing this say bye bye to that
