In different cultural traditions, myths and legends are often closely related to human development, Chinese call themselves the descendants of Yanhuang, when the Xia Dynasty was established, Chinese had already settled in the Yellow River, and in the origin of Japanese mythology, the Japanese islands and gods were born of the combination of Izanagi and Izanami.

One of these gods is the god Amaterasu, that is, the ancestor recognized by the current emperor, in the "Ancient Chronicles", the first generation is Emperor Shenmu, who founded the country before 660 BC, but the first generation of Japanese emperors to the 13th generation of emperors, only recorded in the "Ancient Chronicles", can not find any records in the rest of the literature, these 13 emperors should be fictional characters for the transition from gods to human beings, so the origin of the Japanese is still uncertain.
Nowadays, the most said is Xu Fu Dongdu, Xu Fu Dongdu was first seen in Sima Qian's "Records of History", Xu Fu was known as "Qi people" and "fangshi" proficient in navigation, in 219 BC, Qin Shi Huang sealed Zen carved stones in Mount Tai, and after the end, he rushed all the way to the Bohai Sea, arrived at Zhifu Island, Qin Shi Huang saw some looming mountains and rivers.
Xu Fu wrote that there are three immortal mountains in the sea, Penglai, Abbot, and Yingzhou, and there are immortals living there, and they can seek the elixir of immortality, and in the "Book of History and Zen", it is said: "The world is famous eight, and the three are in the barbarians, and the five are in China", "three" refers to the Three Sacred Mountains, and China at this time has the meaning of central plains and middle earth.
Xu Fu's first trip to the sea was blocked, the second time he went to sea not only with three thousand boys and girls, the "History of Huainan Hengshan Lie" also has: the immortals asked for "a hundred work things" and "the five grains of the five grains and all kinds of work to go", this time Xu Fu took away the grains, craftsmen, ancient books, Chinese herbs and so on.
But Xu Fu is gone, and it is now generally believed in historians that Xu Fu did indeed have the possibility of crossing east to Japan, before the Yayoi period (Qin and Han Dynasties) in Japan, there was no writing, mainly pottery culture, but a large number of copper swords, copper bronzes, and copper doves were unearthed in the Yayoi sites found in Japan.
When Qin Shi Huang sent many alchemists into the sea to go to Penglai Immortal Mountain in order to obtain the elixir, Xu Fu volunteered to tell the Qin Emperor: "There are three sacred mountains in the sea, named Penglai, Abbot, and Yingzhou, and the immortals live in it. ”。
Qin Shi Huang believed Xu Fu's words, and in 210 BC, he recruited three thousand boys, girls, and girls, and went with Xu Fu to Penglai Xianshan to ask for the elixir. This is the reason for Xu Fu's east crossing, and it is also the most widely spread domestic statement that Xu Fu is the ancestor of the Japanese.
In modern times, in Japan, the temple of Xu Fujian is built, and Xu Fu has been worshipped by Japan for thousands of years. From 213 BC to 212 BC, when Xu Fu returned to the Qin state again, he happened to encounter Qin Shi Huang to burn books and pit Confucianism, not accustomed to Qin Shi Huang's tyranny and in order to protect himself, he told Qin Shi Huang that there was an elixir, but because there were sharks in the sea, it was not easy to pass, hoping that Qin Shi Huang could get rid of the shark to get the elixir.
Xu Fu, who had not returned for several years, actually made Qin Shi Huang believe in the words, so he sent troops to annihilate the so-called fish, in fact, it was a few innocent whales, after killing the whales, Xu Fu embarked on the journey of Dongdu again, but this time he went, and never came back. It also left a mysterious package for posterity, but in fact, if you think about it carefully, you can figure it out.
Xu Fu brought various technologies to Japan at that time, such as the cultivation of grain seeds, how to make and use agricultural tools, medicines and production techniques, and medical techniques, and with these technologies, Japan's social productivity increased by leaps and bounds, and the Japanese at that time admired Xu Fu. It is rumored that In addition to these techniques, Xu Fu also carried the Chinese characters of the time, and widely disseminated them, and the current Japanese characters are evolved from Chinese characters, and the authenticity of this statement has yet to be examined.
A large number of bronze artifacts appear in the Yayoi site in Japan, and they are relics from the Qin Dynasty, but according to the genetics detected by historians and scientists and experts combined with historical data, Xu Fu is only the second batch of immigrants to be ushered in by the Japanese archipelago, including the Watanabe yayoi and Ainu.
At the same time, the People who brought agriculture and metal smelting technology to Japan were the Watanabe Yayoi people who immigrated to Japan, and Xu Fu was one of the yayoi people of the Watanabe family. Xu Fu actually came to Japan in order to escape tyranny, not an ancestor, at best, it is to bring some Han people to marry and continue to live with Japanese descendants, tracing back to the roots, Japan with a history of two thousand years, in fact, as early as Xu Fu went to Japan, there were Japanese people, as for the original origin of the Japanese is even more promising.
And it also triggered a large wave of netizens to think about the debate. In the long river of history, what we can know is that the East and Japan have always been closely linked, and there are monks who go to Japan to recite the scriptures and preach, that is, high monks to learn the truth, and the cultural meaning brought to Japan is even more profound.
