Japan Passes China

We all know that China holds a boat load of U.S. debt. And now it seems that someone else has surpassed them....Japan!

What could this mean? We know Japan is in tragic financial condition...if they unravel and can't make their payments...could they cash in their U.S. debt and demand payment from us? And if the U.S. can't refinance that debt...then what happens?
