Graveyard
On a hill there is a graveyard with several standard graves, but the largest grave marker seen so far is the grave of the former queen of the Ryugu Kingdom, Otohime. It is an enclosed crypt with a small wall around it. On top of it is a stone vase-like sculpture with curved handles with a cross on the top of it. Jinbe is currently waiting for Luffy there. It is also Shirahoshi's dream to pay visit there since for ten years was unable to go out from Ryugu Palace. She and Luffy are currently trying to go there.

 * The inspiration for the Sea Forest graveyard might stem from the Japanese forest Aokigahara, also known as the Sea of Trees and often referred to as the forest of death. The place is not only a popular tourist destination, but also became infamous for being a prominent place to commit suicide.
