XD I felt the same than you at the begining but now I realize how it would be difficult to live there because japanese are very shy and many japanese don't accept foreighns, even if you speak japanese perfectly, some of them will always treat you as a stranger. But lucklily, young japanese often love French people so my dream isn't completly over xD if one day you live there, you have to speak perfectly and to have a very good job because life is very expensive in Japan ^^
