The family with surname is still the highest family in Japan, but it is actually a descendant of China.

The Emperor is the highest-ranking Japanese family, but it is not the descendants of China who are still in a fog.

However, if Japan's nobler families are descendants of the Han people. There is a fact:

1. In ancient Japan, only the nobility and samurai class had surnames, while the common people and the emperor did not have surnames (the emperor is a special one)

2. When Han Chinese immigrated to Japan, they all had surnames, that is to say, they almost belonged to that class, but not only Han Chinese immigrants but also immigrants from the Korean Peninsula had surnames.

3. There are quite a few prominent ones, such as Qin clan (who was born in our department and Hattori clan), Wei clan (Shimadzu clan came from Wei clan), Harada clan (Harada clan, Qiuyue clan, Gao Qiao clan, Sakamoto clan, etc.), and so on.
