Wakoku
Wakoku (倭國) was the name used by early imperial China and its neighbouring states to refer to the nation usually identified as Japan.
The Wajin appear in historical documents such as the Book of Han and the Geographical Survey of Japan from around the 2nd century BC.
In 57 AD, the chief of Na-no-Kuni of Wa, which is said to have been located in northern Kyushu (along the coast of Hakata Bay), received a gold seal (King of Na gold seal) from Emperor Guangwu of Han.In the 2nd year of the jianwu zhongyuan reign period [AD 57], the Na state of Wa sent an envoy with tribute.
[Emperor] Guangwu bestowed on him a seal with a tassel.It is believed that this was the result of the consolidation of Japanese polities in northern Kyushu, and that the Yamato State sent an envoy to the Eastern Han Dynasty as a representative of these groups.
A royal tomb dating back to the 1st century BC has been found at the San'unnamikoji site (Itoshima City), which is thought to have been the center of the ancient "Ito Province”.
About 50 years later, in the first year of Yongchu (107), the Japanese king Suishō sent an envoy to the Eastern Han Dynasty and presented 160 slaves.In the first year of the reign of Emperor An's Yongchu, the king of the Japanese kingdom, Suishō, and others presented a hundred and sixty people to the court.The oldest person in Japanese history to have his name recorded in annals, Suishō was also the first person to be named King of Japan in historical records.
In any case, from this time until the end of the 7th century, the political power representing/uniting the Yamato people continued to refer to itself externally as "Wakoku".
[3] When Baekje was destroyed in 660, the Japanese attempted to revive it, and the Battle of Baekgang broke out in 663 between the Tang dynasty and Silla, but they were defeated and forced to withdraw completely from the Korean peninsula.
In the Sangokushi, a history book of the Korean Peninsula, "Shilla honki", December of the 10th year of King Munmu (670), there is an article that reads, "Japan is renamed as the Japanese nation.
The article states, "Japan was renamed as 'Japan' in the 10th year of King Munmu's reign (670), and was named after its proximity to the rising sun.
In the Middle Ages Islamic world, the ninth-century Ibn Khordadbeh wrote "Book of Roads and Kingdoms (Arabic: كتاب المسالك والممالك, Kitāb al-Masālik w'al-Mamālik)" and the "Story of One Thousand and One Nights" (Arabic: ألف ليلة وليلة, Kitāb alf laylah wa-laylah), and as a country east of China and India, al-Wakwak (Arabic: الواق واق, al-Wāqwāq) is mentioned as a place name, which some believe to be a reference to Japan.
