At the west exit of Tokyo station, where real estate is among the most expensive anywhere, throngs of blue-suited business-men pour out every working morning, wearing company pins emblazoned with perhaps Japan's most recognisable company logo: three diamonds. This is Mitsubishi territory. The buildings on all sides house various manifestations of Japan's biggest zaibatsu (industrial grouping). And high above it all stands Mitsubishi Bank.
