Japan used to be a small country During the heyday of China's Tang and Song Dynasties, Japanese sent overseas students to study etiquette, culture and technology in the Tang Dynasty, that is, "sending envoys to the Tang Dynasty". From the perspective of ancient history, China and Japan are still very close. However, I think the relationship between Japan and China only exists in the relationship between dogs and their owners. When dogs find a better owner, they will leave their nests and run for a "great" future.

Language is still an isolated problem. For example, the northern dialect of China is gentle, and there are many exchanges between different regions, so the language and customs are relatively close. In the south, due to geographical and historical factors, there is little communication, so there are great differences in local dialects separated by several kilometers. More importantly, the isolation between Japan and Chinese mainland is much greater than the difference between the north and the south of China.

Whether each region and country can establish a country is related to the cultural, economic, political and historical conditions of each region, but cultural and historical conditions play a more important role.

For example, the ancient Yellow River valley in China had little contact with the south of China, and the territory of Xia Dynasty was limited to the Yellow River valley in China, while the differences among countries in the Spring and Autumn Period and the Warring States Period were as obvious as now. Language differences are also very obvious, just as northerners can't understand Minnan dialect at all now. The impression in your mind that every country is like a country in the Spring and Autumn Period and the Warring States Period is actually because China is now a unified region. Found that I digress, hehe.

To put it bluntly, why is Japan "independent" and not a province of China? Because China never really occupied it. Never assimilated Yamato from culture.
