I think it all goes to every other foreign countries. You must adapt to its language (unless it's English) and adapt to its culture. It's an SOP if you want to migrate or work into any other country, not just Japan. People like to live in Japan for many other reason as it is one of becoming one of the most livable city and you can almost leave your bike outside your house without getting stolen. And I almost forgot, there's pikachu and mario almost everywhere, how'd you like that?
