It's not anti-japanese to suggest that Japans OTL 1940s leaders weren't exactly rational and moderate people. Which is why conflict with the US is all but inevitable. And Japan has no way to resolve that conflict outside of a) backing down or b) going to war.
The timing should be taken into account. The peak of ultra-nationalist feelings in Japan has happened in 1936. After Imperial Way Faction was purged after failed coup d'etat 26 February 1936, the gradual trend has begun for pacification of Japanese policy. The war in China of 1937 was the last pure conquest. By 1941, the Japanese were thinking mostly about survival in hostile political environment rather than about exploiting an expansion possibilities. Therefore, the Pearl Harbour 7 December 1941 was in fact an unusually far-planned DEFENSIVE ATTACK operation. A harbinger for the "Strategic Defense Initiative" concept (which is also oxymoron). Reading history, the Yamamoto`s force waited with attack until it was confirmed what the Japanese diplomats have failed to make a reasonable terms with US.
So, keep military situation relatively "cold" up to 1974 and Japan may become rational enough to back down in China. May be. The trends are unreliable, because it take so long to allow hard-liners to die out. Japan can be defeated a half dozen times meanwhile.
