Japan originally had no name. In ancient Japanese mythology, the Japanese called themselves "eight continents" or "eight islands".

According to the Records of the Later Han Dynasty, Japan was called "Japan" or "Japan" in ancient China. After the unification of Japan in the 5th century, it was named "Yamato".

In the second half of the 7th century, the Japanese envoy to the Tang Dynasty changed the name of the country to "Japan" according to the title in the letter of the Emperor China, meaning "the place where the sun rises", which has been in use ever since. The Japanese have always regarded the sun as a totem.

After the Sui and Tang Dynasties, Japan began to accept Chinese culture on a large scale. With more and more understanding of China culture, Japan became increasingly dissatisfied with the title of "Japan". According to "Biography of New Tang Dynasty in Japan", in the first year of Xianheng (67), Japan sent an envoy to the Tang Dynasty. At this time, Japan had "learned Xia Yan a little, hated its name and changed its name to Japan". The messenger spoke for himself, because he came out recently and thought it was a name. " Therefore, the name of China was given by the Emperor of Sui Dynasty unintentionally.

China's shadow can be seen everywhere in the Japanese cultural pedigree. Japanese, medicine, tea ceremony, diet, archery, costumes, etiquette and the "Yayoi culture" which has a far-reaching influence on Japan are all influenced by China. Especially, the Book of Rites written by China in ancient times was introduced into Japan, and it developed into the so-called "Yamato Civilization".

Origin of Japanese culture: Since 1996, archaeology and anthropology in China and Japan have repeatedly confirmed that the Japanese nation is mainly composed of Tunguska people in Siberia, Han people in ancient China, coastal people in southern China in ancient times, a small number of Wuyue people in the lower reaches of the Yangtze River, a small number of Malays in Nanyang Islands and Indochina people in Indochina Peninsula.

Japanese cultural integration: Japan used to have no characters, so China's Chinese characters have been used all the time. About 8% of Japanese language accents are Chinese inflections. Japanese language and pronunciation mainly come from the integration of China dialect accents and Indo-China accents from Shang and Zhou Dynasties to Qing Dynasty, so Japanese culture has been deeply influenced by China. Japanese absorption of China culture is a multi-faceted, long-term historical process of thousands of years.
