One Piece Card Game OP-17 The World's Strongest Warriors Is Confirmed for August 26, the First Global Simultaneous Set
Bandai has dated the 4th Anniversary booster: OP-17 lands August 26, 2026. Starting with this set, the Japan-first window is gone and the game goes fully global on day one, with the Treasure Rare back as the top chase.
One Piece TCG Ends the Japan-First Era for Good
Bandai has confirmed the headline number One Piece players have been waiting on: OP-17 "The World's Strongest Warriors" arrives August 26, 2026. The set was officially dated by the @ONEPIECE_tcg_EN account on June 13, and it carries a milestone that matters far beyond a single release date.
Starting with OP-17, the One Piece Card Game moves to a global simultaneous launch. The familiar Japan-first window, where English-language players waited weeks or months for product the rest of the world already had, is gone.
Why "The World's Strongest Warriors" Is a Big Deal
This is the 4th Anniversary booster, which Bandai has historically used to swing for the fences. Expect a deep, power-forward checklist aimed squarely at competitive players, plus the premium chase structure the game has leaned into over the past year.
- Release date: August 26, 2026, worldwide and simultaneous.
- The hook: the 4th Anniversary set and the first true global drop.
- The chase: the new Treasure Rare rarity returns, sitting above Secret Rare with roughly one per set.
What the Simultaneous Release Changes for Collectors
The old release gap created a strange secondary market. English singles often launched into prices already shaped by months of Japanese results, and import sellers built entire businesses on the delay. With that gap closed, price discovery should happen everywhere at once.
When the whole world opens the same boxes on the same day, the early-pull arbitrage that import sellers relied on largely disappears. That is good news for the average collector.
How to Play This One
Pre-orders are already live at retail partners across the US, Europe, and Asia. Anniversary sets tend to sell through quickly, and the Treasure Rare is the kind of single that anchors a box's entire value. If you plan to buy sealed, lock in a pre-order at MSRP rather than chasing a marked-up box in September. If you only want specific singles, waiting a week or two after launch is usually the smarter financial move once supply settles.
