I won't presume to give advice since I'm not in your shoes, but I will say that I tend to agree with Vanessa and Dameon; my first instinct absent other considerations would be to leave Japan as soon as I could. But I know that life is rarely as simple as we might wish it to be, and individual considerations are usually more complex than they appear to others. But know that I am wishing you nothing but good luck with the entire process.
