Can you speak fluent Japanese?

If not, then why would they choose someone who can't speak Japanese, when there are perfectly capable people living in Japan already?

If you want to be part of the English marketing team for games, that would be a good idea, but you would need to speak some Japanese too.

If not, design games where you are now. America and the UK are doing well for gaming at the moment, so that would be your best bet.

For any game design job, you need an outstanding portfolio, a degree, and work experience. Any design or media based job is very competative with many people all wanting the same job. You have to be better than everyone else.
