In the "History of Great Japan", it is recorded that Achi was the great-grandson of the Han Ling Emperor.
Why is it that in the history books of Japan, there are great-grandsons of emperor HanLing? Moreover, at the annual Liu clan meeting, there are often some Japanese people who come to participate, and they are still VIPs. What is even more surprising is that these people actually claim to be descendants of Liu Bang, the ancestor of Han Gao, although none of them is surnamed Liu!

Japanese people with some surnames, claiming to be of Chinese descent, experts: don't want to admit it but really. The beginning and end of the story will be explained in detail below.
These Japanese are all related to the "Achi" mentioned above. According to historical records, after Cao Pi usurped Han, the descendants of Emperor Xian of Han were not killed by him. However, in the last years of the Western Jin Dynasty, due to the turmoil in the world, so in May 289, Liu Azhi, a descendant of Emperor Xian of Han, believed that the situation in the country was not very optimistic, so in order to avoid war and save the family, he led the clan and the population of the seven surnames and seventeen counties to the east to the area of present-day Japan.
According to the "Secretary of Japan", Liu Azhi gathered the people and informed them: "Today there will be chaos, and if I stay here for a long time, I am afraid that there will be disasters of destruction, and I have heard that there is a holy son of heaven in the eastern country of Japan, which can be avoided." ”
Although the distance between Japan and China is not far away, in terms of the navigation conditions at that time, Liu Azhi's decision can be regarded as a completely adventurous activity. After several years of preparation, Liu Azhi took his people and his followers, a total of 2,040 people, out of Mainland China and headed for Japan.
In 299, on September 5, the twenty-ninth year of Emperor Yingshen of Japan, Liu Azhi and his party officially arrived in Japan, and their words on this trip were to visit Japan as chinese emissaries.
And the Japanese emperor also knew that on the other side of the sea, there was a powerful empire. And now that this empire has allowed so many people to come to Japan, he naturally does not dare to despise it. So he arranged for Liu Azhi and his followers to settle in Hinomae Village, Ōwa Kokugashi County, and gave him the title of Envoy of the Eastern Han Dynasty.
After settling in Japan, Liu Azhi's ethnic group was known as the "Watanabes" by the locals. Because they brought a group of craftsmen and literati with them when they crossed the east, they brought advanced scientific and technological and cultural knowledge to Japan, as well as agriculture, craftsmanship and technology, which promoted the development of Japanese civilization, so the local residents respected them very much.
It was soon welcomed by the Emperor of Japan. Liu Azhi was appointed as a Tibetan official and given a large number of food estates. Later, the Liu Achi family and its followers began to spread out in Japan, and were distributed in Settsu, Omi, Harima, Mikawa, and Awa.
According to the "New Family Name Record", Liu Azhi's son Liu Duhe was given the surname "Zhi", also known as "Eastern Han". Since then, the Liu Azhi family has branched out and scattered, and has continuously derived many clans.
After several generations of integration, the part of the people brought by Liu Azhi at that time were also fully integrated into Japanese society, and their surnames were all changed to Japanese surnames.
According to incomplete statistics, there are as many as 47 surnames with Liu Azhi as the ancestor, including: the Ōzo clan, the Sakaue clan, the Harada clan, the Takahashi clan, the Tanbashi clan, the Potae clan and so on.
Moreover, the surnames with Liu Azhi as the ancestor were not just created in Japan, and a considerable part of these surnames developed very well in later times.
Take the Harada family, for example. The Harada clan is one of the oldest nobles in Japan today, and in its genealogy, Liu Bang, the ancestor of Han Gao, is their common ancestor.
In Japan, the Harada clan is also one of the more famous surnames in Japan, and as a newly created surname by a descendant of China, it is quite remarkable that it can develop to this point in Japan. It is said that it has now reached the 93rd generation of Liu Bang, who also established the Han Taigong Temple in Fukuoka City, Kyushu, and made regular sacrifices. In addition, he often goes to Xi'an and Jiangsu in China to worship his ancestors.
Another surname is the Ōzo clan, which has always been responsible for the finances of the imperial court, such as the Ministry of Finance in Japan, which was once named the Ministry of Finance. In addition, there is the Tanba family, which has been responsible for the medical treatment of the Japanese Imperial Family for thousands of years. The famous Han physician Danbo Yuanjian also claimed to be a descendant of Liu Xie, the Emperor of Han Xian, and he also had a Han name, called Liu Baoting.
The most noteworthy is the Takahashi family, which has a high social status in contemporary Japan and belongs to the hereditary nobility. As the third largest surname in Japan, its roots are actually in China.
Therefore, many Japanese people now insist that they are after Liu Bang, the ancestor of Han Gao, and some are more explicitly called after Emperor Xian of Han, in fact, they are the descendants of Liu Azhi when he crossed the east to Japan.
What do you think about that?
