Tokyo One Piece Tower: Tongari Shima no Dai Hihou

This film is part of a temporary event at Tokyo One Piece Tower, linked to a real-life treasure hunt collaboration with Takarush Corp. called Treasure Hunting: Tongari Shima no Daibouken. Visitors work through clues from ancient documents discovered by Luffy, Usopp, and Chopper to locate the hideout of an enigmatic creature named Tongari Ton. The movie plays after completing the treasure hunt, showing the Straw Hat Crew mistakenly opening a chest in a cave, believing it to contain the island's treasure.
