Second what MMM said

and as far as being an engineer is concern, I think it will be easier if you obtain your engineering degree in Japan, or if you further your study in Japan and eventually move into a research role.

It is very difficult for foreign graduuate of any engineering discipline to build a career in japan, not even with the required language skills.

Note I said difficult, I didn't say impossible, but it will be a very very challenging task
