Japan is a country deeply influenced by China, whether it is the japanese common script, or the Japanese culture in the tea ceremony, etiquette, clothing are strong with Chinese elements, so in the international Japan is also circulated "Little China" a name, but the Japanese never admit that they have too much to do with China.
Japan's earliest contact with China was in the Sui and Tang dynasties, in 607 AD, Japan sent emissaries to meet the Sui Emperor, but Japan wrote in the national book: The sunrise of the heavenly son to the book day is not where the heavenly son is unharmed, Japan calls itself the sunrise heavenly son, the Sui Emperor is the sunset, which makes the Sui Emperor how happy, this diplomacy has also failed.
However, before the Sui and Tang Dynasties, there were few records of Japan, and the origin of the Japanese has always been a mystery, the earliest chinese record of the Japanese is in the "Classic of Mountains and Seas", and the "North Classic of Hai Nei" of the Zhou Dynasty records: Gai Guo is in the south of Juyan, the north of Wu. It belongs to the Yan, and some of the rest of the literature also records that Chinese migrated to the Islands of the East China Sea in large numbers.
At present, there are more than 25,000 Ainu people living in Hokkaido, and they belong to the East Asian type of Mongolian race, is this Mongol race the origin of the Japanese? This is difficult to know, but the Japan Institute of Genetics conducted a genetic study of the Ainu people and Okinawans in Hokkaido.
They examined a genetic comparison between Jomon women and modern humans from 3800 years ago, and the results of the genetic test were mainly that the Jomon and Yayoi people were more mixed, while the Hokkaido and Okinawa regions retained more genetic traits, that is, the Japanese were mixed with Jomon and Yayoi.
What is a Jomon? Some experts believe that the Jomons are the most primitive Mongol race, belonging to the eastern ethnic group of Siberia, the Urchi and the Nevkh in North Asia, a Russian ethnic group, currently located in the lower reaches of the Heilongjiang River, and the Yayoi people carry the Yayoi culture.
Yayoi culture is about the Yayoi pottery unearthed in Japan and named, at this time China coincided with the Qin and Han Dynasties, in the Yayoi culture sites, there are also a large number of copper swords, copper copper, copper duo and so on. The forging bronze technology of the Qin and Han dynasties was relatively developed.
Some scholars believe that copper appeared in Japan, the Qin and Han dynasties Chinese a large number of Dongdu, of which Xu Fu is a representative figure, the Japanese literature Xu Fu biography, there are also Japanese national heavy weapons three: Yue sword, Yue mirror, Yue seal, all Qin system also, Xu Fu although disappeared in history, but undoubtedly caused an impact on Japanese culture.
During the Han Dynasty, Emperor Wu of the Han Dynasty established four counties in Korea in 109 BC to rule northern Korea, and the Han people began to move to Korea, but in 313 AD, The Joseon Dynasty overthrew the Han Dynasty ruling institutions, and some of the Han people who stayed there returned to the Han Dynasty and some moved south.
In the "Nihon Shoki", there are also: Ying Shen fourteen years, is the age, Bow Moon Jun led one hundred and twenty prefectures from Baekje to Japan, the Japanese also call this part of the Han people "naturalized people" or "Watanabe people", although it is a little unpleasant to say, but most of the Japanese are mixed races, although Japan has repeatedly emphasized its own single ethnicity, but it is impossible to ignore the evidence.
