The ancient name of Japan-Japan

"Anti-Japanese Map" (Part) In the Korean drama "Dae Jang Geum", the Japanese are called enemies, and people familiar with history know that they were also called in the Ming Dynasty. This name is related to ancient Japanese names. The ancients called Japan a Japanese country, also known as a slave country, while "Kou" was a general term for bandits or invading troops.

Calling the Japanese "Japanese" or "Japanese" is a general term for Japan in ancient China. This statement was first seen in Shan Hai Jing, followed by Han Shu. According to the geographical records: "There are Japanese in the Sea of Le Lang, divided into 100 countries", which may refer to many small tribal countries with Kitakyushu as the center. Japan and China established diplomatic relations long ago. As early as the second year of Jianwu in the Han Dynasty (57 years), the Japanese slave countries sent envoys to the Han Dynasty to pay tribute, and Guangwu also gave them a seal. This gold seal was unearthed in Shiga Island, Fukuoka City, Japan on 1784. It is engraved with the words "Slave of King Han Wei", which confirms the records in the history books. However, it is generally believed that the "slave country" is only Nuo County near Hakata, Kitakyushu. Later, in order to call Japan "Japan" for convenience, it was called "Great Japan" after the great transformation in 646.
