Did the Japanese immigrate from Chinese mainland at the end of the Eastern Han Dynasty?

Not all of them. Generally speaking, there are Polynesians and Tunguses, Han people and Koreans. Even in Japan, the so-called Japanese nation is a nation in the process of formation!

Except the Ainu people living in Hokkaido, other Japanese devils are descendants of immigrants, whether they admit it or not. Ha. There is a theory with a large number of fans in Japan that the Japanese gradually evolved from the ancient ice age humans who occupied the island of Japan 20 thousand BC. Another theory widely circulated in Japan holds that the Japanese are descendants of a nomadic people who conquered Japan by crossing the Korean peninsula in the 4th century-but who are those riders? There is no doubt that they are by no means Koreans. There is a theory that is very popular with western archaeologists and Koreans, but it is very unpleasant in some circles in Japan, that is, the Japanese are descendants of Korean immigrants who arrived in Japan with rice farming technology in 400 BC. Finally, the fourth theory points out that it may be the ethnic integration mentioned in the first three theories that formed the contemporary Japanese nation.

"China Rural Society and Japanese Mainland Immigrants Organization" further cuts into the relationship between war and population movement, pointing out that every great turmoil in Qin, Han, Wei, Jin, Southern and Northern Dynasties caused the population of Liaodong to flow from north to south, some of which were absorbed by the three Koreas and some fled to Japan. "Wu State, Wu People and Wu Culture" absorbed the research results of Japanese archaeologists on triangular prism animal mirrors unearthed in Japan, and compared them with the records in China history books one by one, and determined the "Wu State" in Japanese history books, Jiangnan, China. In 473 BC, in the battle of wuyue in southern Jiangsu, Fu Cha, the king of Wu, died, and the country was ruined, which triggered the migration of Wu adherents "south to Guangdong". Some of Wu's subjects and descendants of the royal family went into exile and lived in today's Liang Shu, China and other countries, becoming the ancestors of Jiangsu in the ancient history records of, such as The Book of Jin, The History of the North and Yuan Gui. Japan's newly written surname records also record the history of descendants of the King of Wu and adherents of the State of Wu who traveled to Japan: "Matsuno, after the King of Wu Fu Cha, Wu people came to me today." According to the Japanese Minister, the oldest history book in Japan, in the third century BC, three brothers from Wudi traveled to Japan to teach local people sericulture techniques. According to Wu Kao, "When Wu died in the early Warring States, a large number of descendants of Wu moved to Vietnam." At the same time, "the younger brother of He Lv, the king of Wu, fled to Chu because of the failure of the coup, and later changed his surname to Fu in Wu, which is a branch of Wu. Some members of Fuxi's family migrated to the Korean peninsula to develop their inheritance, and the population was extremely prosperous. Later, it developed into a famous Korean family-Baekje Royal Family. "

From the 3rd century to the 6th century, Soochow, Eastern Jin Dynasty, Song Dynasty, Qi Dynasty, Liang Dynasty and Chen Dynasty successively established their capitals in Nanjing (called Jianye and Jiankang), making Jiangsu a political, economic, cultural and foreign exchange center in southern China. The Dongwu ship sailed overseas and had frequent trade and diplomatic exchanges with Korea, Japan, Minnan (now Cambodia) and Lin Yi (now central Vietnam). As an important commodity of the Maritime Silk Road, Wudi Silk is exported to Japan, Rome and other countries. At that time, Nanjing had a group of craftsmen with textile and mirror-making skills, ranging from stone gold to overseas living in Japan, Korea, southern Fujian and other countries. At the same time, there are also immigrants who have emigrated overseas through official communication channels between China and foreign countries. Liang Shu (Biography 48) recorded that in the fifth year of Wu Dong's Huangwu reign (AD 226), Jia Renqin's theory of Roman Empire came to an end. Watanabe satrap Wu Miao, sent Sun Quan. Ask about the local customs and say. When Zhuge Ke begged Danyang, he won a short man. View: Daqin wants to see this person. There are ten men and ten women on the right, and the officials must record Liu Xian's essays. Salty is better than the way things are. After returning home. "According to the Japanese history book" The History of Japan ",in the thirty-seventh year (Wu Dong Jiahe six years, AD 237), Japan" sent envoys from Dujia to Wu via North Korea. Be a sewing worker. After the prince of Wu and Yuan, Wu Zhi and Xue Zhi returned to their four daughters "; In the year of Emperor (Yongjia five years in the Western Jin Dynasty, AD 3 1 1), "I went to Wu and asked for a weaver girl"; In the eighth year of Xionglue (the sixth year of Daming in the Southern Song Dynasty, AD 464), I sent Bode to Wu ... In the fourteenth year, I was ordered to send him to Wu, because I could darn four people. "Since the Six Dynasties, due to a large number of craftsmen and other expatriates who went to Japan from Wudi to engage in textile, sewing, pottery making and other skills, Japanese folks often called China Wu Ren, China Wu Yin and China Wu Yuan.

Take Tang as an example for the specific sailing time.

After leaving Nanpu Port, the Tang envoy fleet sailed along the Japanese coast and finally began to cross the sea in the northern part of Jiuzhou. The early route was to go north near the Korean Peninsula and land in northern Shandong Province, China via Bohai Sea. Later, I crossed the East China Sea directly and landed in Yangzhou and Mingzhou (now Ningbo) in Chinese mainland. It takes a long time, usually one or two months. In the fourth year of Zhenguan in Tang Dynasty (630), the son of Emperor Pingcheng really came to China by Zhang Zhixin of Tang Dynasty. In the second year of Huichang (842), Tang Bo of Li Churen set sail from Akasaka Island (now Wudao Islands) and crossed the East China Sea in six days to reach Lecheng County, Wenzhou. In the second year of Dazhong (847), Zhang Zhixin, a clean Tang Bo, set sail from Wanghai Town, Zimingzhou (now Ningbo), crossed Dong Jiao and reached Jiao Jia. It only took three days, which was the shortest voyage and time record at that time.
