I am a current PhD student, still a couple years off from graduation. I'm still keeping my options open, but I've started to idly consider interesting places to do a postdoc.
Fit with a mentor and relevance of research is of course the most important thing, but the postdoc period is also a chance to live in cool places for a few years at a time. Work-life balance is also pretty important to me, though, and I have heard some crazy stories about work-life balance in general in Japan.
How is it in Japanese academia as a postdoc from the west? Does it depend on who you work for/what university you are in, or where you're from?
For reference, I did a bachelors in the US and a masters and (currently) PhD in Finland, where home life is highly respected and you're basically not expected to work on weekends/evenings unless you want to.
Edit: If it's relevant, my field of study is genetics, but I mostly work on the computer and don't expect to have much to do with wet lab experiments in the future.
