Some judge is going to make a list a assets (very small relatively, and probably includes cash accounts unless this dude was simply spending the cash), and a lits of liabilities (huge).  Liabilities will be represented by debt holders who will form a line (usually following bankruptcy law -Japan I guess) and the assets will quickly get paid out (sometimes fractionally) to the folks at the head of the line.  You will be at the back of the line, rest assured - probably simply because you are not local and not Japanese.
