If you only remember one date from this article, make it August 28, 2026 — that’s when OP-17 “The World’s Strongest Warriors” hits shelves worldwide, and it’s the first time Bandai has coordinated a true simultaneous global street date for a mainline One Piece Card Game booster set. After that, EB-05 “Heroines Edition vol.2” lands October 30, and a still-unconfirmed OP-18 is rumored for late November. Here’s the full calendar, what’s actually solid vs. still a rumor, and what’s worth preordering right now instead of chasing hype.

One Piece Card Game has earned this kind of release-calendar attention lately — per TCGplayer’s Q2 2026 GMV numbers, it has now outsold at least one “Big Three” TCG competitor for three straight quarters, so the constant drumbeat of new sets isn’t a niche hobby thing anymore, it’s a genuinely mainstream release cadence collectors need to track.

Where things stand right now (as of August 12, 2026)

The most recent mainline set on shelves is OP-16 “The Time of Battle”, which released in Japan on May 30, 2026 and in the US/English market on June 12, 2026. We already did a full pull breakdown of that set — see our OP-16 Time of Battle set review if you’re still hunting Manga Rares from it. Right behind it, the six-color ST-31 through ST-36 starter decks dropped July 11 (JP) / July 31 (US) as a low-cost way to try each new archetype before OP-17 arrives.

That means as of this writing, OP-17 hasn’t released yet — it’s still two weeks out. Anything claiming to sell you “OP-17 boxes in stock” right now is either a preorder (fine, if it’s a reputable seller) or a red flag.

OP-17 “The World’s Strongest Warriors” — August 22 (JP) / August 28 (Global)

This is the game’s 4th anniversary set, and it’s built around it: the set spotlights the Four Emperors — Edward Newgate (Whitebeard), Shanks, Kaido, and Charlotte Linlin (Big Mom) — plus Elbaf Arc characters. Per BANDAI’s official English site, packs are priced at $4.99 with 24 packs per box, matching the standard OP booster format.

What’s confirmed:
– Japan release: August 22, 2026
– Global (US/English) release: August 28, 2026 — and per multiple retailer trackers, this is being treated as Bandai’s first true day-and-date worldwide launch rather than the usual weeks-long gap between JP and EN print runs.
– Releasing alongside it: DP-12 (Double Pack Set Vol.12) and new Official Card Sleeves, both also dated August 28.
– Premium Bandai is also dropping two collector exclusives that same month: a Premium Card Collection -Best Selection Vol.6- ($25) and an “English Version 3rd Anniversary Set” ($120).

The caveat: early “chase card” price projections you’ll see floating around right now (Japanese secondary-market outlets have already posted six-figure-yen estimates on parallel Leader cards) are pre-release speculation based on character popularity, not actual settled market data. Those numbers reliably come down — sometimes by 50% or more — within a few weeks of a set actually hitting the secondary market in volume, once early FOMO buyers finish overpaying. Treat day-one price lists as a vibe check, not a price guide.

Will OP-17 really launch worldwide on the same day?

Not quite — there’s still a six-day gap between the Japanese release (Aug 22) and the English/global release (Aug 28), which is actually the tightest window Bandai has run for a mainline set. It’s a meaningful step toward simultaneous global releases, not a literal same-day launch. If you’re ordering real Japanese product through an import retailer, expect to see it listed before your local game store has English copies.

What’s officially confirmed after OP-17

Bandai’s English site has already listed these products with dates, so treat this tier as solid:

• SD-01 “Set Sail Deck Set” — September 18, 2026. Two ready-to-play decks, aimed at new players rather than the competitive scene.
• ONE PIECE Heroines Special Set — September 2026, $70 (Premium Bandai exclusive).
• EB-05 “ONE PIECE Heroines Edition vol.2” — October 30, 2026, $4.99/pack, 24-pack boxes. This is the sequel to EB-03’s Heroines Edition, again spotlighting characters like Nico Robin, Nami, and Boa Hancock. Per early rarity breakdowns it runs 1 Leader / 29 Common / 21 Rare / 9 Super Rare / 1 Secret Rare / 8 Special cards — a small, single-Leader pool.
• TS-03 “Mini Case Set Vol.3” — October 30, 2026, six tin variations.
• DP-13 (Double Pack Set Vol.13) and a Live Action Edition vol.2 Premium Card Collection (Straw Hat Crew and Baroque Works versions, $20 each) — November 2026.

The caveat here is a real one: Extra Boosters like EB-05 are collector-focused. With only one new Leader and a heavy skew toward Special/parallel cards, EB sets historically add very little to the competitive Leader pool compared to a mainline OP release — great for binder pages and cosplay-adjacent cards, weak for deckbuilding unless you’re already running a Heroines-color Leader.

OP-18 — what we think we know (and why you shouldn’t preorder off it yet)

Unofficial product-tracking accounts (not Bandai) are circulating early info suggesting OP-18 lands around November 20, 2026 and will give a long-requested character their first-ever Leader card, alongside a leaked rarity spread (6 Leader / 45 Common / 30 Uncommon / 26 Rare / 10 Super Rare / 2 Secret / 6 Special / 1 Treasure / 1 DON!!). As of this writing in August 2026, none of that — the date, the character, or the rarity count — has been confirmed by Bandai. Early-info leak accounts themselves flag this as subject to change or outright cancellation.

The caveat: this is the part of the calendar where speculative preordering gets risky. Retailers sometimes open “OP-18 booster box preorder” listings off leaked info before Bandai’s own announcement, and if the set shifts (wrong month, different theme, a delayed date), you can end up with a canceled order or a refund headache. Wait for Bandai’s own product page before putting money down on OP-18 specifically.

2027 and beyond

Bandai hasn’t announced anything concrete for 2027 yet. Based on the cadence since 2022 (roughly one mainline OP set every 10-12 weeks, with an Extra Booster or premium product filling most of the gaps), a reasonable expectation is OP-19 landing sometime in Q1 2027 — but that’s an inference from pattern, not a confirmed date, so don’t build a preorder budget around it yet.

Full 2026 release calendar

Prices vary by retailer and region; treat all “~” dates as unofficial until Bandai’s own product page confirms them. Not financial advice — card and sealed-product prices move fast, and speculative preordering on unconfirmed sets carries real cancellation/refund risk.

What to actually buy right now

If you want to be genuinely ready for OP-17 without gambling on leaks, the moves that make sense today are: (1) lock in an OP-17 preorder from a retailer with a clear cancellation policy, and (2) use the next two weeks to fill gaps in already-released sets while pricing is settled instead of speculative. A few real, currently available options through Discovery Japan Mall (which ships genuine Japanese product worldwide):

• BANDAI ONE PIECE Card Game: The Seven Heroes of the Blue Sea (OP-14) Booster Box — the most recent mainline booster this mall currently stocks; a solid pickup if you’re still filling out an OP-14-era pool before OP-17 shakes up the format.
  
• BANDAI ONE PIECE Card Game Extra Booster ONE PIECE Heroines Edition (EB-03) Booster Box — the predecessor to EB-05, worth grabbing now if you like the Heroines theme, since vol.2 is still two-plus months out.
  
• BANDAI ONE PIECE Card Game Premium Booster ONE PIECE CARD THE BEST Vol.2 (PRB-02) — a reprint-heavy 10-pack box that’s a cheaper way to backfill staple cards while you wait for OP-17 pricing to settle.
  
• Starter Deck Purple/Black Monkey D. Luffy (ST-26) or Starter Deck Green/Yellow Yamato (ST-28) — cheap, complete 51-card decks if you just want to be playing something this week instead of waiting on a preorder.
  
  

One honest caveat on buying import product for a brand-new set: JP-export retailers like this one typically restock a few weeks after a set’s Japan release, once the initial domestic allocation settles — so don’t expect OP-17 boxes to show up on import marketplaces on August 22. For day-one OP-17 pulls, your best bet is a Western LGS or major online retailer’s official preorder; use import mall stock for catching up on sets that already released, like OP-14 and EB-03 above.

FAQ

When does OP-17 release in the US?
August 28, 2026, six days after the Japanese release on August 22. Bandai’s English site lists packs at $4.99 with 24 packs per booster box.

Is it safe to preorder OP-18 already?
Not from unofficial listings. As of August 2026, Bandai hasn’t officially announced OP-18’s date, theme, or Leader lineup — everything circulating is from leak-tracking accounts, which explicitly flag their info as subject to change. Wait for Bandai’s own product page before committing money.

Should I buy OP-16 product now or wait for OP-17?
Both, for different reasons. OP-16 is the current competitive format and its prices have already settled, so it’s a safer buy if you want to know exactly what you’re getting. OP-17 is worth preordering if you want day-one access to new archetypes, but expect chase-card prices to swing for the first few weeks after release.

Where can I safely buy real Japanese One Piece Card Game product from outside Japan?
Stick to retailers that show clear stock/inventory (not just a preorder page with no cancellation terms) and that explicitly sell sealed, unopened product — that’s the safest way to avoid the counterfeit-card risk that follows loose singles bought from unverified sellers online. Import marketplaces that ship genuine Bandai product, like Discovery Japan Mall, are a reasonable option for sets that have already released; for day-one new-set pulls, a Western LGS preorder is usually faster.

Do older sets like OP-06 or OP-12 still work in tournaments?
Yes, both of those are still Standard-legal — but “every set works forever” stopped being true this year. One Piece Card Game’s first rotation took effect on April 1, 2026: Block 1 (OP-01 through OP-04 and the earliest Starter Decks) left Standard, while OP-05 onward — including OP-06 and OP-12 — remains tournament-legal. Rotated cards are still playable in the separate Extra Regulation format. Beyond legality, the competitive meta also shifts every time a new set adds Leaders with better rush/counter tech, so an OP-06-era Leader that was strong in 2023 may simply be outclassed today rather than banned or rotated.

Bottom line: OP-17 on August 28 is the release that actually matters for preordering right now — everything past that (EB-05 in October, a rumored OP-18 in November) is either confirmed-but-distant or still unofficial. Lock in OP-17 through a retailer you trust, use import stock to fill gaps in already-released sets like OP-14 and EB-03, and hold off on spending real money against OP-18 leaks until Bandai actually says something.
