Sea Forest

The Sea Forest (海の森) is a graveyard somewhere in the Ryugu Kingdom. Jinbe is currently waiting for Luffy here. It is also Shirahoshi's dream to see it and she and Luffy are currently trying to go there. It has a lot coral growing around it. There are several shipwrecks here. On a hill there are several standard graves. The largest gravemarker 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.

Trivia
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.
