Are the Japanese descendants of Mongolia?

The Japanese were migrated by the Malays thousands of years ago. The Malays and Japan's indigenous Ezo people fought a thousand-year war. In the end, the Ezo people were defeated and forced to retreat to Hokkaido. , there are only more than 20,000 people left today. After the Malays arrived in Japan, they had a small amount of integration with the local Ezo people, gradually forming today's Japanese tribe. These are prehistoric things, so the formation of the Japanese nation is far away. Earlier than Xu Fu's eastward journey, Xuzhou's eastward journey could be said to have played only a minimal role in changing the Japanese ancestry. It mainly played a role in cultural dissemination and other aspects. It is said that Xu Fu founded the first country in Japanese history in Japan.
