the quality of Japanese food depends solely on the quality of the ingredients more than the skill of the chef. The latter is still taken into account to a certain degree of course, but the former takes priority. I think that's why it doesn't quite reach the level of the other two.
Case in point, I was out for dinner the other night in Kobe and we ordered a tomato dish. It was, simply, a sliced tomato on a plate. No salt, no dressing, no garnish, nothing.
It was the best tomato I have ever eaten.
