What is the origin and history of Japanese names?

The origin of Japanese names: Ancient Japanese worshipped the sun god, so they took the sun as their totem. According to legend, at the beginning of the 7th century, Shoto Kutaishi of Japan wrote in a letter to Emperor Yang Di: "The prince comes from Japan to the sunset prince", which is the embryonic form of Japanese country name. It was not until the second half of the 7th century that Japan sent Tang Shi to change the country name to "Japan", which means "the place where the sun rises", that it became the official country name of Japan.

The history of Japanese names:

During the Eastern Han Dynasty, Japanese islands had contacts with China. According to the Records of the Later Han Dynasty, about 100 small countries were established on the island of Japan in 57 AD, and one of them sent envoys to pay tribute to China. Because the emissary was short, thin and small at that time, Liu Xiu, Emperor Guangwu of the Eastern Han Dynasty, awarded the title of Japan, a dependent country of China at that time, to his emperor and the title of King of Japan to him.

And awarded it to the king of the slave country. 1954, the Japanese government designated this gold seal as a first-class national treasure. During the Three Kingdoms, the Jin Dynasty and the Southern and Northern Dynasties, we always called Japan a "slave country" and called the Japanese "Japanese".

Note: According to the Records of the Later Han Dynasty, Emperor Guangwu of Han Dynasty gave the king of the slave country a golden seal and declared Japan a slave country. At this point, Japan has a name and become one of Dahan's more than 50 vassal countries.

With the Japanese understanding of Chinese characters in China, they feel the Japanese meaning, that is, dwarves, in order to eliminate this discrimination. Using the word "He" with the same pronunciation as Japanese, plus the word "Da", the national title of Japan is "Dahe".

In 607, Sister Xiao Ye, the Japanese ambassador, looked like an official document of the Sui Dynasty, expecting China to change its name to Japan. But at the beginning of the book, where the sun rises, the son of heaven makes the book day safe. This made Emperor Yang Di feel very wronged. He thought he was the only son of heaven in the world and ignored Japanese demands.

According to the Book of Song Dynasty, after the death of the first Japanese king Zan, four heirs, Zhen, Ji, Xing and Wu, moved to worship the history and asked the China government to change the title given to Japan. It was not until the stage of Wu Zetian in the Tang Dynasty that she was finally willing to give Japan the name of the country.
