One Piece Day dates back to 2017, when the Japan Anniversary Association designated July 22 as the official date honoring the manga’s 1997 debut in Weekly Shonen Jump. The celebration has grown from a single press conference into a multi-day global broadcast. This year’s calendar also includes a separate One Piece Fest in Los Angeles for the first time, scheduled on August 25-26, reflecting Toei’s plan to expand its overseas footprint.
