For you kids keeping score at home, you can slide Nintendo up to the number three spot on your wall chart of most valuable Japanese companies, right there behind Toyota and Mitsubishi UFJ Financial Group (that's Japan's largest bank, but you already knew that).

Make sure you're writing all this down for those internet flame wars you've been practicing for.
