Since the premiere of the anime adaptation of the manga series One Piece by Eiichiro Oda in 1999, Toei Animation has produced 15 feature films based on the franchise traditionally released during the Japanese school spring break since 2000. Four of the films were originally shown as double features alongside other Toei film productions and thus have a running time below feature length. The first three films were shown at the Toei Anime Fair and the eleventh was released as part of Jump Heroes Film. The films generally use original storylines, but some adapt story arcs from the manga directly. With the release of films ten, twelve, thirteen, and fourteen, tie-in story arcs of the TV series were aired concurrently.
