Sea Forest

The Sea Forest (海の森) is a place in the north-east section of Fishman Island known as the Ship Graveyard.

It has a lot coral growing around it, more so than normal due to the light emitted by the Sunlight Tree Eve. It is populated by all kinds of sea fauna, including schools of fish and large whales. There are also several shipwrecks there because sunken ships are dragged there by the ocean currents, thus the epithet "Ship Graveyard". The Thousand Sunny was swept here when the Straw Hats entered Fishman Island. According to Robin, there is a possibility that a Poneglyph is hidden there. She is currently searching for it in a coral forest.

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 and a cross on the top of it. Jinbe meets Luffy here for the first time in two years. It is also Shirahoshi's dream to pay a visit there since for ten years she was unable to leave Ryugu Palace. Shirahoshi has arrived there with Luffy, Sanji, Chopper, Hatchan, and Megalo and she is now sitting in front of her mother's grave.

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.
