What postgraduate course areas could I explore with a degree in Japanese?

I need to start thinking of my long time future, and have already decided I want to go for a Masters in Translation, but what other fields could this lead me into? If I took Japanese with another subject (either another language, International Relations or Development Studies, not sure yet) then this path will become wider… but any preliminary ideas?

I would suggest taking it with another subject, like you said – to widen your opportunities. But only if you feel comfortable in studying that other subject.

Base it on where your strengths and interests lie.
