Japs are pretty heavily controlled by the American elite. There is actually a fairly big underground movement in Japan to throw them off and stop stuff like this from happening. Japanese banks and politicians though have been paying tribute to America for a long time.
It's a tough thing to reference. But I've read from many Japanese authors about the kind of reverence that Japan holds for America even today. It's almost a religious kind of awe, and so when American powerbrokers visit Japan there is a kind of unsaid understanding that the Japanese aristocrats will make concessions and "pay tribute". After WW2 all the current Mitsubishi Group banks very much became an international operation. And it holds tremendous power, and yet is extremely - almost inexplicably - conciliatory to America.
Some Japanese people are unhappy with this vassal kind of relationship between their most powerful institutions (which, let's face it, are the political Kingmakers of Japan just like the corporatocracy in America) and the Western Elite.
