Maybe a little bit "cliche" question but that's my question.

I want to be a Concept Artist and work in the Videogames industry I want to study in Japan. I would love Tokyo or Kyoto, maybe Osaka.
Some good schools?

And well, something a little silly but I'm pretty new to this, what do I need to study to be a Concept Artist?
I mean, what do I have to look for in the studies program from colleges?

And for those who live in Japan, how much would be the costs of living and studying there?
And the last question, what kind of level in Japanese should I have to study in Japan?

Sorry if my english is weird.
