In Japan, there are many documents about Xu Fu being the ancestor of the Japanese. Japanese folks also call Xu Fu Saturnalia, and some families find that their ancestors' surnames are not Japanese, but? Qin? Surnames are also written in the same way as China's Chinese characters. Even Japanese archaeologists discovered this kind of thing carved on the tombstones of some people's ancestral graves during their investigation? Qin? Word, so most scholars in the world generally believe that Xu Fu did not go back after landing on the main island of Japan, but stayed in the Kanto Plain of Japan, where he settled and multiplied with his own crop seeds and thousands of children and men, becoming the earliest ancestor of the Japanese. In ancient Japanese literature, they called Xu Fudi Emperor Jimmu.
Then why didn't Xu Fudong return to Qin after crossing Japan? The answer, we can follow the historical records to find the reason. According to relevant historical records, Xu Fu was the last disciple of a generation of strange man Guiguzi and an outstanding artist in the Qin Dynasty. Proficient in martial arts, monasticism and alchemy, he was highly valued by Qin Shihuang.
Therefore, Qin Shihuang later handed the task of finding three fairy mountains in the East China Sea to Xu Fu, hoping that Xu Fu would take 3,000 children, men and women and hundreds of craftsmen to find immortals and seeds of various crops on the fairy mountains and exchange them with elixirs. After Xu Fu bid farewell to Qin Shihuang, he finally landed on the island of Japan after many hardships. I didn't expect there were no immortals here, and there was no so-called elixir of life. Chui fook, who has lost hope, is very afraid. He is afraid that he will not be able to do anything when he returns to China. Qin Shihuang will put himself and his men to death, so he finally chose to stay on the island of Japan to establish his own country and become the ancestor of the Japanese.
