According to the Book of the Later Han, in 57 CE, Emperor Guangwu of Han granted Nakoku an imperial seal, patterned after the Chinese jade seals, but made of gold: the king of Na gold seal. In return, that same year, Na sent envoys to the Chinese capital, offering tribute and formal New Year's greetings. This seal was discovered over 1500 years later, by an Edo period farmer on Shikanoshima Island, thus helping to verify the existence of Nakoku, which was otherwise known only from the ancient chronicles. Engraved upon it are the Chinese characters (Kan no Wa no Na-no-Koku-ō, "King of the Na state of the Wa (vassal) of Han".
