Moody’s downgraded Japan, from double A2, to double A3.  Moody’s cited continuing government budget problems, huge government debt, and government incompetence.

One of the signs of government incompetence is what has become a revolving door of government agencies and leaders.  The latest change is that Prime Minister Naoto Kan has resigned, effective by the beginning of September.

Japan is the second largest foreign holder of U.S. government debt.
