ONE PIECE DAY’26 runs this weekend — August 22–23, 2026 — at Makuhari Messe in Chiba, and the timing lines up with something card game collectors can’t ignore: booster pack 「世界最強の戦士」【OP-17】 releases on August 22, the exact same day as the event’s Premiere Eve Festival, marking the game’s 4th anniversary. A dedicated ONE PIECE CARD GAME SPECIAL stage runs the next afternoon, and the official word from organizers is that it will deliver “world’s fastest” new card game information.
If you’re outside Japan and didn’t get a venue ticket — ticket lotteries closed back on July 20 — none of that locks you out. Every stage segment streams free on YouTube, X, and LINE, no ticket required. This guide covers exactly what to watch for, when to watch it in your own time zone, and how it overlaps with OP-17’s launch weekend.
ONE PIECE DAY’26 (Aug 22–23, Makuhari Messe Halls 4–6) streams free on YouTube, X, and LINE (no region restrictions are mentioned in the official materials). The ONE PIECE CARD GAME SPECIAL stage airs Aug 23, 12:40–13:25 JST (03:40–04:25 UTC), promising “world’s fastest” new card game information — the same slot format that world-premiered the OP-13 teaser at ONE PIECE DAY’25. OP-17 itself releases Aug 22, the same day as the event’s Premiere Eve Festival.
ONE PIECE DAY’26 Schedule: What Matters for Card Collectors
ONE PIECE DAY’26 is split across two days at Makuhari Messe’s International Exhibition Hall, Halls 4–6, in Chiba, Japan — the event returns to Makuhari after last year’s edition at Tokyo Big Sight. Saturday, August 22 is the “ONE PIECE DAY’26 プレミア前夜祭” (Premiere Eve Festival), running 13:00–18:00 with a stage segment from 18:15–19:45. Sunday, August 23 is the main event, running 9:00–18:30.
On-site tickets were ¥1,980 per day (tax included), sold through a two-round lottery that closed on July 20 with results issued July 27 — so if you don’t already have one, no general sale has been announced as of publication. That’s exactly why the free livestream matters for overseas collectors: it’s the confirmed way to follow the event in real time without a ticket.
The headline programming both days centers on the finale of the 2nd ONE PIECE Character World Popularity Poll, “WORLD TOP 100” — ranks 100 through 31 are revealed August 22, with the top 30 counted down August 23. It’s the event’s main draw for the broader fanbase, and it’s also the backdrop the card game segment sits inside on day two.
For collectors specifically tracking the ONE PIECE Card Game side of the show, the one segment to circle is the ONE PIECE CARD GAME SPECIAL stage on August 23 — covered in detail next.
The ONE PIECE CARD GAME SPECIAL Stage
Tucked into the Sunday programming is a dedicated 「ONE PIECE CARD GAME SPECIAL ステージ」, scheduled for 12:40–13:25 JST — a 45-minute window inside the wider Aug 23 stream block. The stage has been billed by organizers as delivering “world’s fastest” (世界最速) new ONE PIECE Card Game information, language that points to some form of new-set reveal or first-look content rather than a recap of what’s already public.
What exactly gets shown hasn’t been detailed anywhere we could confirm as of publication, and we’re not going to guess at a set name or number here. What we can point to is precedent: the same stage format at ONE PIECE DAY’25 was where the teaser video for booster 「受け継がれる意志」【OP-13】 was world-premiered, roughly two weeks ahead of that set’s actual release. That’s the closest comparable data point for what “world’s fastest new booster info” has meant in practice at this event before.
We’ll be covering the reveals as they land, and if a new set does get shown on stage, our OP-17 release date, card list, and pre-order guide is the hub we’ll keep updated first.
How to Watch the Free Livestream from Abroad
All ONE PIECE DAY’26 stage programming streams free on the official ONE PIECE YouTube channel, plus X and LINE — both added as live-stream platforms for the first time this year, alongside YouTube which has carried the stream in past editions. No ticket, account tier, or region unlock is mentioned in any of the official scheduling — just the stream link when it goes live.
The two streaming windows are August 22, 18:15–19:45 JST, and August 23, 10:30–18:30 JST. The card game stage sits inside that second window. Here’s the card game stage specifically, converted for planning purposes:
| Time Zone | ONE PIECE CARD GAME SPECIAL Stage |
|---|---|
| JST (Japan) | Sun, Aug 23 · 12:40–13:25 |
| UTC | Sun, Aug 23 · 03:40–04:25 |
| US Eastern (EDT, UTC−4) | Sat, Aug 22 · 23:40 – Sun, Aug 23 · 00:25 |
| US Pacific (PDT, UTC−7) | Sat, Aug 22 · 20:40–21:25 |
In other words, US East Coast viewers should tune in right around midnight Saturday into Sunday, and West Coast viewers around 8:40–9:25 pm Saturday evening. For any other region, working from the UTC line above and adjusting for your own offset is the safest approach, since JST doesn’t observe daylight saving and stays fixed at UTC+9 year-round.
If you want the full context of the poll countdown and other stage segments rather than just the card game slot, the broader Aug 23 window (10:30–18:30 JST, 01:30–09:30 UTC) covers the whole day’s programming on the same three platforms.
Organizers are also running a stream-specific incentive: following @Eiichiro_Staff on X and posting with the hashtag #ONEPIECEDAY during the August 23 stream enters you into a draw for 30 winners of event goods sets . Eligibility and prize-shipping terms for overseas entrants aren’t specified in the official materials.
The OP-17 Launch Weekend Overlap
Booster pack 「世界最強の戦士」【OP-17】 releases Saturday, August 22, 2026 — the same calendar day as the ONE PIECE DAY’26 Premiere Eve Festival, and the set also marks the ONE PIECE Card Game’s 4th anniversary. That’s not a coincidence of scheduling collectors should read too much into beyond what it is: two separately organized things landing on the same date, with release-commemoration events running at official shops nationwide starting that same day, separate from the ONE PIECE DAY venue itself.
Put together, the weekend of August 22–23 has three things happening in parallel for card game fans: OP-17 hits shelves and official-shop events on the 22nd, ONE PIECE DAY’26 runs its two-day program at Makuhari Messe, and the card game stage caps things off on the 23rd with whatever new information organizers have queued up. None of that is guaranteed to connect — OP-17 is confirmed to release that weekend regardless of what airs on stage — but the timing means anyone following OP-17’s launch has extra reason to also have the Aug 23 stream open.
For what’s actually in OP-17 itself, the set’s headline cards include a Kaido legend card illustrated by Baki creator Keisuke Itagaki, the card game debut of Rocks D. Xebec, and a new Crew Super Parallel rarity featuring Rocks D. Xebec and Monkey D. Luffy. We cover the full breakdown — including which cards are shaping up as chase pulls and pull rates for the set’s best cards — in our dedicated guides, and our booster box and case buying guide is there once you’re ready to plan a purchase. As of August 19, 2026, our own Japanese OP-17 booster box pre-order is live at ¥28,000, shipping from Tokyo on or after August 24. Our current Japanese One Piece booster box lineup also ships from Tokyo, and Quick Order remains the fastest route for mixed or bulk requests.
Venue Promos and Merchandise
ONE PIECE DAY’26 has its own commemorative card product, but it’s worth being precise about where it’s actually sold: the 「ONE PIECEカードゲーム プレミアムカードコレクション -ONE PIECE DAY’26-」 goes on lottery sale through Premium Bandai starting August 22, and organizers have specifically noted it is not sold at the ONE PIECE DAY’26 venue itself. The set reportedly contains one Monkey D. Luffy promo card (P-161) and one ONE PIECE DAY’26 DON!! promo card.
On the general merchandise side, confirmed visitor benefits tied to the ¥1,980 ticket include a WORLD TOP 100-themed leisure-sheet bag, a customizable “oshi card” attached to the admission pass, and a Chopper coloring activity added later in the run-up. Past editions have paired ONE PIECE DAY with their own card game promos — ONE PIECE DAY’25 distributed an Elbaf DON!! card as a venue benefit, and ONE PIECE DAY’24 handed out a new-artwork Luffy promo to exhibition-area visitors on both days. As of this writing, no equivalent venue-exclusive card game promo has been confirmed for ONE PIECE DAY’26; we’ll update this guide if that changes. If you’re chasing past ONE PIECE DAY promos or other Japanese One Piece singles, flag them via Quick Order and we’ll source them from Tokyo.
What “World’s Fastest New Booster Info” Might Mean
It’s worth separating what’s actually confirmed from what’s reasonable to expect. Confirmed: the ONE PIECE CARD GAME SPECIAL stage on August 23 is described as delivering “world’s fastest” new information about the card game. Not confirmed: which set, if any, that information covers. We haven’t seen a set name, number, or release window attached to that stage segment in any official source, so we’re deliberately not naming one here.
The useful comparison is what happened at the last edition. ONE PIECE DAY’25 ran August 9–10, 2025, and its card game programming is where the OP-13 teaser video was world-premiered — roughly two weeks before OP-13 itself released on August 23, 2025. If ONE PIECE DAY’26 follows a similar pattern, the stage would be the place a next-set teaser or first-look would logically surface, given OP-17 has already released the same weekend rather than being upcoming. But precedent isn’t a guarantee, and organizers haven’t spelled out the content beyond the “world’s fastest” framing.
Either way, the stage sits inside the free stream window, so overseas collectors don’t need to wait on secondhand recaps to see whatever does get shown. We’ll be watching along with everyone else and updating our OP-17 coverage the moment there’s something concrete to report.
Where to Follow Along
For the stream itself, the official ONE PIECE YouTube channel, X, and LINE are the three confirmed platforms. On X, @Eiichiro_Staff runs the official stream and #ONEPIECEDAY campaign, while @ONEPIECE_tcg is the account to watch for any ONE PIECE Card Game-specific product or promo announcements tied to the event. The official event site (onepiece-day.onepiece-base.com) exists as well, though content updates are typically posted via ONE PIECE.com news rather than the event site itself.
On our end, we’ll be tracking the card game stage in real time and folding anything confirmed into our OP-17 hub guide. If you’re building an OP-17 order around the launch weekend and want help sourcing specific cards or sealed product once it’s available, our Quick Order page is the fastest way to reach us directly, and the current One Piece card box collection is live for everything already in stock.
