Is Japan a nice place to go and study in? Or is it racist and unwelcoming?

Question:

Answer:

Being the most homogeneous country on earth, you'd think they're racist. But I do think their reserve and stoicism are what make some people think they are racist. For example, you board a train and sit next to a Japanese (of course), they seem to instinctively turn away from you. I've been to Japan only on short stays and I didn't notice any overt dislike for foreigners.

And yes, it is very expensive to live lthere. Tokyo is among the most expensive cities in the world.
