Japan originated there.

As for the origin of the Japanese nation, or the origin of the Japanese, academic circles are still controversial. From the physical structure, various opinions can be roughly divided into three categories: (1) "the theory of ethnic replacement", which holds that there has been one or even two ethnic replacement in the Japanese archipelago. For example, in the 1980s of 19, the cutting scientist Yoshinori Ogi believed that the aborigines living in the Japanese archipelago in the rope-grain era were Ainujin people, who were driven to the north by other ethnic groups in the mainland after the rope-grain era. (2) The "half-blood theory" holds that the "original Japanese" (Japanese in Paleolithic Age) mixed with other nationalities who migrated from the mainland or Nanyang Islands after the rope-grain age, and gradually formed the modern Japanese. Kenji Kiyono, a medical scientist, first put forward the "half-blood theory", which remained the mainstream of academic circles until the 1930s. (3) The "evolution theory" (or "continuum theory") holds that the Japanese in the rope-grain era gradually evolved into people in the Yayoi era, people in the ancient grave era and even modern Japanese due to changes in their lifestyles. It pays more attention to the inheritance of race, neither agrees with the theory of "race replacement" nor pays much attention to the influence of mixed blood on the composition of Japanese nation. After World War II, Ren Yan of Hasebe and Professor Suzuki of the Anthropology Research Office of the University of Tokyo held this view, which still has an influence on the academic circles.

There is also a saying that Xu Fu went out to sea in the Qin Dynasty to ask for an elixir. There is the following statement:

Emperor Jimmu, the first emperor in Japanese history, came to Japan. In archaeological research, combined with the doubt of "the history of the eight dynasties", this statement seems reasonable until the existence of these nine emperors is proved. There is Xu Fuzhi's tomb in Japan, but it was built quite late, which was built by the annex when the legend of Fulai Xu Tian was introduced to Japan (Note: [2]). Moreover, there are too many tombs of Xu Fu, such as the tomb of Yang Guifei, with dozens of back and forth, which can only increase doubts.

Become the ancestors of the Japanese. No matter from the point of view of history or archaeology, the era of this theory is very different. Japan was inhabited long before Xu Fu arrived and had its own culture. Chui fook with the arrival of virgins, at best, just intermarry with local people to reproduce.

According to "A Brief History of Japan", in seventy-two years of Xiaoling, Fu Laixu was born in Qin. (Or cloud, Xu Fu led three thousand men and women, and hired three tombs and five classics. If you can't ask for medicine, stay and don't come back. Or clouds, stop at Mount Fuji. Or cloud, bear wild mountain, there is Xu Fu Temple. ) "said chui fook with boys and girls to Japan to repair, pay tribute to the three tombs and five codes, and ask for fairy medicine, but he couldn't get it, just waiting to settle down. In the Fuji Document, it is mentioned that Fu Laixu went to Japan to assist local farmers in farming and brought some new technologies. However, Fuji Document is generally regarded as a fake book by academic circles.

After arriving in Japan, Xu Fu never returned home, and he didn't get the elixir. Worried that Qin Shihuang would kill him, he asked his men and women to change their surnames to Qin, Dian, Futian, Haneda, Futai and Fukuyama. Coincidentally, Lianyungang also has Yuntai Mountain range, and all surnames have a strange origin with mountains. At present, there are Japanese surnamed Qin in Shinto Palace in Wakayama Prefecture, Japan, and the word "Qin" is engraved on the upstairs of some houses.

Go to Ryukyu Islands or an island in Bohai Bay and then go to Jeju Island. Lost in the storm at sea. Interestingly, from the Emperor Uto to the Emperor Kameyama, the emperor's main sacrifice was more than 80 times, and it didn't stop until the Meiji Restoration.
