Japanese social system in World War II

Constitutional monarchy is incomplete.

The military has a high degree of autonomy. Because the shogunate is in power. This is an ancient tradition. Meiji Restoration failed to destroy it.

During World War II, the emperor was no longer in power.

This is also the time when World War II broke out. Why does the Japanese military department have so much power? And the role of the emperor is very close to that of the king of England.

So the constitutional monarchy is very close.

All countries have different social systems. So don't compare the British social system with Japan and say that Japan's constitutional monarchy is incomplete! Just as China's social system is different from that of the Soviet Union, China's social system is also incomplete.

Hope to adopt with pure hands-Xie (I don't know what to ask, I have to answer)
