Are the Japanese descendants of the people Zheng He brought with him when he went to the West?

There is no conclusion about the national origin of the Japanese. Most scholars believe that it is a cross between people from different sources. The Japanese are the only hybrids at present. As early as the late Paleolithic period, when the Japanese archipelago was still connected with the Asian continent, primitive people lived here, and their descendants are the Ainu people today. About 654.38 million years ago, the Japanese archipelago began to separate from the Asian continent, and many immigrants moved in from the sea one after another, which became the foundation of the Yamato nation. They mainly include Tungusic people from Siberia and northeastern China, Malays from Nanyang Islands, Indosinians from Indian zhina Peninsula, Wuyue people from the lower reaches of the Yangtze River, and Han Chinese and Koreans who moved in around A.D. Because of the different time and place of settlement of each group of immigrants, although they have formed a unified nation after thousands of years of mixed living, there are still many local differences in traditional culture, lifestyle and physical characteristics. Thousands of years before BC, the inhabitants of Japanese islands lived by fishing, hunting, gathering or slash-and-burn agriculture, which historically belonged to the rope culture era. From the 3rd century BC to the 2nd century AD, Chinese mainland's metal tools, kiln-fired pottery and rice cultivation techniques were introduced into Kyushu, Japan through the Korean Peninsula, which was the Yayoi cultural era. In the 3rd ~ 4th century, the Yamato State was established with Nara as the center, which unified all the tribes in Japan. Since then, it has been called Yamato Nation. In the 7th-8th century, Japan absorbed the culture of agriculture, handicrafts, architecture, Buddhism, etc. in China's prosperous Tang Dynasty, and at the same time absorbed the culture of Korea and India, and its social economy developed rapidly. After the Meiji Restoration, a large number of European and American cultures were absorbed, forming a great fusion of eastern and western cultures.
