How many years is Japan's history?

Archaeological studies have found that primitive humans from northeast China entered the Korean peninsula hundreds of thousands of years ago and some migrated to Japan. Archaeology and anthropology hold that the Japanese nation is mainly composed of Tungusic people in Northeast Asia, ancient Zhongyuan people, a small number of Wuyue people in the lower reaches of the Yangtze River, a small number of Malays and Indosinians in Indochina Peninsula, and gradually migrated to Japan and evolved. Since 1996, the investigation team composed of Chinese and Japanese archaeologists, anthropologists and medical experts has repeatedly confirmed the above conclusions. There is also an immigration route from eastern China to Japan. There are no characters in Japan, so China's Chinese characters have been used all the time. The Japanese archipelago did not appear until the 4th century. Before that, there were only tribes. The Japanese archipelago was not originally called Japan. In ancient Japanese mythology, the Japanese called it "eight continents" and "eight island countries". In addition, in Chinese, "Fusang" and "Japan" are also nicknames of Japanese country names. According to the records in Hanshu and Houhanshu, China called Japan "Japan" or "Japan" in ancient times. In the middle of the 4th century, Japan began to become a unified country, called Yamato.
