New information on the Writers Guild of America (WGA) website suggests that a fourth season of Netflix's live-action adaptation of One Piece could be released as early as 2027.
While Netflix has not officially confirmed a fourth season, the WGA website lists staff for One Piece season 4 with an associated date range of "2027-2028." This update follows earlier speculation based on a message from an organizer of The One Con convention, which indicated that cast members might begin filming a new season in December 2026. Filming for the third season officially concluded on June 30, 2026.
The live-action One Piece series debuted in 2023 to significant viewership, overcoming skepticism about adapting the beloved manga. Season two premiered in March 2026, with season three slated for release in 2027. The potential 2027-2028 release for season four indicates a continued rapid pace for the production.
Season two of One Piece saw the Straw Hat crew reach the Grand Line, encountering new adversaries and recruiting Tony Tony Chopper. The season also focused on Princess Vivi of the Alabasta kingdom and her struggle against Baroque Works. Season three is expected to depict the Straw Hats going to war to aid Vivi and her kingdom.
If season three adapts the entirety of the Alabasta Arc from the manga, season four could potentially follow the Straw Hats to Jaya and their journey to an island in the sky. The WGA listing, while not an official confirmation from Netflix, aligns with previous leaks and suggests a consistent production cycle for the series.
