Shika Island
Two farmers found the golden seal on a hill overlooking Hakata Bay in 1784. The area was made into a park called Kin-in Park to celebrate the discovery. The seal is known as the Golden Seal of the King of Na and is a national treasure. Chinese records state that about 2,000 years ago, Emperor Guangwu of the Han dynasty gave a golden seal to a Japanese envoy to present to their king. The seal had the characters 「漢委奴国王」"(Han wa na koku-ō"), which means "[From the King of] Han, presented to the King of Nakoku". The seal is now kept at the Fukuoka City Museum.
