My brother got on a scholarship to go to university in Japan, he was given a year an half language training and then had to apply to Japanese universities.
I suggested he study in Osaka as I'd visited there and knew some people he could hang about with but he was advised not to study too far away from Tokyo as people would look down on him if he gained a regional accent.
Is this actually the case? I appreciate that they might make fun of locals with a regional accent but is would this apply to foreigners too?
