Kin'in park
Kin'in park is a park located in the southwest part of Shikanoshima, and is where the gold seal, "kin'in", was found in 1784. The gold seal was rediscovered during farm working, and was kept by the Kuroda clan, the head Fukuoka Domain, until it was donated to the city of Fukuoka in 1978. It was a part of the collection of Fukuoka Art museum from 1978 to 1990, and is now displayed at Fukuoka City Museum.
The King of Na gold seal, commonly known as "kin'in", is believed to be the gold seal that Emperor Guangwu, of Chinese Han dynasty, conferred bestowed on a diplomatic official visiting from the Na state of Japan. No other artifacts of this period, besides this gold seal, have been found at Shikanoshima, making the reason why the gold seal was found at this island a mystery. There are various theories about the exact location of the rediscovery.
There is a memorial and a replica of the gold seal displayed at the observation plaza, at the top of the park.
From the Kin'in park has a beautiful view of the island of Nokonoshima and the busy seaway of Hakata bay can be viewed. Also, it is a good place for seeing the sunset.
Kaen-zuka
Kaen-zuka is a place where Buddhist monks of Kōyasan prayed for the surrender of the Yuan dynasty of China, at the behest of retired emperor Kameyama, during the Mongol invasion in 1281. Since after the Mongolian army retreated, the monks left behind the kaen, the flaming halo put behind a statue of Fudo-Myō'ō, the place became to be called Kaen-zuka.
A small temple and some small shrines remain. It is located in the forest between Shikaumi shrine and Shiomi park.
Mōko-zuka
Mōko-zuka is a mound with a memorial tower built for memorial service for the soldiers of the Mongolian army, who died in the Mongol invasions in 1274 and 1281. Stone memorials such as one with an inscription written by Zhang Zuolin are placed around the tower.
In the first invasion in 1274, a Mongolian ship ran aground on the coast of Shikanoshima and the captured soldiers were executed. In the second invasion in 1281, Mongolian troops landed on Shikanoshima, making it a battle ground.
The Mōko-zuka used to be on the hill just west of the current location, but since it was destroyed in the 2005 Fukuoka earthquake, it was rebuilt in the current location. A statue of Buddhist priest Nichiren and Kubikire-kutsu have been built in the original location.
