There is something about the ocean that has always drawn people in. It could be the mystery of what lies beneath the surface of the vastness that can be seen stretching out as far as the eye can see.

Whatever it may be, there is no doubt that tales set at sea have always been popular. Anime is no exception, with many anime taking place either partially or entirely on boats sailing across the ocean.

What is an ocean anime?

An ocean anime is an anime that is set, at least in part, on the ocean. This can mean that the story takes place entirely on a boat, such as in Blue Submarine No. 6, or that there are episodes that take place on the ocean and land, like in One Piece.

Some ocean anime focus on the creatures that live in the sea, such as mermaids in Mermaid Melody Pichi Pichi Pitch. Whatever the focus may be, all of these anime have one thing in common: they are set against the backdrop of the ocean.
