Hello forum goers. I have a question about job availability.
I am currently studying software development in University and I understand that as long as you have a degree you can get a job in Japan as an english teacher. However I want to know a few things.

A) Are there any IT Jobs for foreigners in Japan?
My Japanese as of now is pretty mediocre (I only use it for reading and playing import games) but if I improve it how much of a difference will it make?
C) If I go to Japan after I get my degree is there some place or way I can study a masters while there?

Thank you.
