I was wondering if anyone had an experience applying to different university for Ph.D. after finishing Masters degree. I searched around this sub-redit as well as English MEXT pages (mext.go.jp), but can't find anything concrete. Even whether it's possible seems to be a grey area. People on campus say "we knew students who did that", but again, nothing concrete.
If any of you had hands on experience or know someone who had, please share.
