Someone of you knows something about the phd in Japan?

No problems, this is ok.
Maybe he will ask you when you can come over there.

good answer...thank you

Yes, sure: looking for a job is strange activity because if you have a phd then you are too qualified, but if you don't have it, you have not specialized enough.

It is strange, because it seems that you need the phd for "that specific job", but, it has been a waste of time when you got it...

Almost all jobs need the repetition of the same things at infintive.
A good job for me is when you can continue to learn many things, you can become an expert in a subject, you can realize an idea.

is a phd important to find a good job after?
