Please help me analyze the characteristics of ancient Japanese politics. thank you

The political feature of ancient Japan was aristocratic politics, which was very similar to that of Europe. Because of this, Japan succeeded in reform and China failed.

The greatest advantage of Japanese aristocratic politics is the balance of power, and the supreme ruler cannot be unscrupulous. For example, how did Japan come from during the Warring States Period? If the general doesn't give him strength, he will rebel underground, which is not negotiable. China was an absolute monarchy in ancient times, but Japan did not, or did not reach the level of China.

The nobles in China disappeared after the Tang Dynasty, and Huang Chao almost killed all the nobles in Chang 'an. Some nobles in the Tang Dynasty even lost their genealogy, and then the aristocratic system was not established. Since the Song Dynasty, scholars and scholars have come to power. Many of them come from humble origins, and they have been trying to enter the upper class all their lives. Without the support of their families, they did not dare to challenge the imperial power, so the absolute monarchy in China became more and more serious.
