How did Japan get its name?

Japan's name is in the east of Asia and the northwest of the Pacific Ocean. It was called Bazhou State, Weiyuan China and Weiyuan Mizuho State in ancient times. In Emperor Jimmu's time (42 BC), the place where the country was founded was called Yamato, which means "harmony" or "Yamato". In Japanese, yamato is a mountain, and to means place. Yamato originally refers to a mountainous place, which is a country name named after the terrain. Later, Daiwa became the name of Japan for a long time. In ancient times, China and South Korea were called Japan and Great Japan. According to the Japanese pronunciation of Japanese characters, it is the same as Yamato. China's ancient book "History of Han Geography" said: "There are Japanese people in the Sea of Le Lang who come to see the clouds at the age of 100." 1784, a gold seal was unearthed on Shiga Island, Fukuoka Prefecture, Kyushu, engraved with "King of Han slaves", which was given to a king in Kyushu by Emperor Guangwu of the Eastern Han Dynasty in 57 AD. Accordingly, the Japanese name was introduced from China. It is also said that the name of Japan was introduced from North Korea. Ancient Koreans called Kyushu "yemato" and later called Japan. Later, I used the name Japan myself. One is from Japan, which evolved from this country. In Izumo State (now Shimane Prefecture) in ancient Kyushu, there is a river called He Fei, and the basin along the river is called Hefeifei. Japanese writing hinokuni(hi is fertilizer, no is it, kuni is place). Japanese, Chinese and Japanese (sun) are homonyms for fat, both of which are hi. Countries and places also use the word kuni together, so later they came from. In 645 AD (the first year of Dahua), Emperor Kotoku of Japan acceded to the throne, and through Dahua innovation, the whole territory of Japan was unified. In order to distinguish the previous Yamato regime, the official name of the country is Japan, which is a combination of Yamato and Hino, and the two sounds of Hino and mato are merged into Japanese books (Hino, in which mato is transliterated as moto). It means the country where Japan originated. In 607 AD, when Japan sent its envoys to the Sui Dynasty, it was said in the credentials that "the son of heaven came from Japan, and there was no son of heaven on the day of writing", and "Biography of Dongyi Japan in the New Tang Dynasty": "The emissary said it himself, and the country became famous recently" all explained the meaning of a Japanese name. There are two pronunciations of Japanese country names: Nippon and Nihon. The former is the Chinese pronunciation of a Japanese name, and the latter is said to be the name of ancient Koreans.
