Such scholarships are incredibly interesting to me, but my plans for the future involve my staying in the US for quite some time. However, though life is short, there' plenty of time to make a visit or two to where ever I should like, so perhaps Japan will be one of those places!
It's funny you should mention formerly studying to be a nurse, because that is what I am currently doing. I have one more year to go, then I get to test for my license.
I wish you the best of luck with your future and with your pursuit of that scholarship!
