Roger, how good is your Japanese ability? Do you expect to communicate with bosses and colleagues in Japanese, and read written material in Japanese? I think this information will help folks here provide you with a more accurate assessment, since it has a big effect on the job opportunities.
Hi omae, thanks for your response. I fully understand that almost all communication will be in Japanese.
At the moment I can speak up to a business level and I know all the kana, my kanji and reading ability are a bit lacking in comparison though but I can concentrate on that with a tutor in the next year or two.
I don't plan on moving there immediately though but if my language skills still aren't up to scratch then perhaps working in a western company would help at the start? I think they normally use English.
