Toei Animation is bringing ONE PIECE back to Seattle this spring with a second collaboration alongside the Seattle Mariners. ONE PIECE Night returns to T-Mobile Park on March 31, coming for the Mariners’ home game against the New York Yankees. Their previous collaboration was on April 8, 2025.
Following last year’s inaugural event, the 2026 edition again centers on Monkey D. Luffy and the Straw Hat Crew, combining the anime fandom with Major League Baseball’s opening-week atmosphere. Tickets for the themed night are available exclusively through the Mariners’ official site, and each theme ticket includes a commemorative ONE PIECE x Seattle Mariners baseball jersey.
The evening will also feature pre-game activities tied to the ONE PIECE Card Game, with demos and jersey pickup windows beginning in the afternoon at Victory Hall before gates open at T-Mobile Park. Jersey distribution continues into the early innings of the game, while the first pitch is scheduled for 6:40 PM local time.
ONE PIECE Night Schedule Highlights (as of February 4):
- 2:30 PM: ONE PIECE Card Game demos and early jersey pickup begin (Victory Hall)
- 5:10 PM: Stadium gates open; jersey pickup resumes outside Section 339
- 6:40 PM: Seattle Mariners vs. New York Yankees
The ONE PIECE anime, based on Eiichiro Oda’s manga, is set to resume weekly episodes this April with the start of the Elbaph arc. In addition, the plan from 2026 onward will be to have up to 26 episodes per year, with each episode adapting one manga chapter.
Given last year’s sellout, tickets for the March 31 event are expected to move quickly.
