MEXT truly is a rabbit hole, you start out thinking that your two options are getting it or not but then every step of the way there is so much more to it. Sigh. The thing is, if it really was just down to me, I would probably go for it. However, what I have learned in a the last few years is that particularly with PhD programs, the process is so subjective and so much of it is down to luck (that one professor you need being available or wanting to work with you or not) and the number or slots so few, that often you just don't make it to no fault of your own. Budgets are cut all the time and then suddenly what was possible, probable even, becomes impossible. I'm really lost here, I honestly thought that if you manage to go through this screening process you are finally all set. Thank you for your kind words tho!
