ONE PIECE DAY’26 ran on August 22–23, 2026 at Makuhari Messe in Chiba, and the timing lined up with something card game collectors could not ignore: booster pack 「世界最強の戦士」【OP-17】 released the same day as the event’s Premiere Eve Festival. A dedicated ONE PIECE CARD GAME SPECIAL stage was also on the program, billed by organizers as delivering new card game information.
Venue tickets were sold by lottery, but viewers outside Japan who didn’t get one were not locked out of any of it: every stage segment streamed free on YouTube, X, and LINE, no ticket required, and the card game slot converts to any time zone from the JST schedule.
ONE PIECE DAY’26 at Makuhari Messe streamed free on YouTube, X, and LINE, with X and LINE carrying the stream for the first time. The ONE PIECE CARD GAME SPECIAL stage ran inside that free stream.

ONE PIECE DAY’26 Schedule: What Mattered for Card Collectors
ONE PIECE DAY’26 was split across two days at Makuhari Messe’s International Exhibition Hall, Halls 4–6, in Chiba, Japan — the event returned to Makuhari after the previous edition at Tokyo Big Sight. The program opened with 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, followed by the main event, running 9:00–18:30.
On-site tickets were ¥1,980 per day (tax included), allocated through a two-round lottery that closed on July 20 with results issued July 27. That is exactly why the free livestream mattered for overseas collectors: it was the confirmed way to follow the event in real time without a ticket.
The headline programming on both days centered on the finale of the 2nd ONE PIECE Character World Popularity Poll, “WORLD TOP 100” — ranks 100 through 31 were revealed at the Premiere Eve Festival, with the top 30 counted down at the main event. It was the event’s main draw for the broader fanbase, and it was also the backdrop the card game segment sat inside.
For collectors tracking the ONE PIECE Card Game side of the show, the segment that mattered was the ONE PIECE CARD GAME SPECIAL stage.
The ONE PIECE CARD GAME SPECIAL Stage
Tucked into the main-event programming was a dedicated 「ONE PIECE CARD GAME SPECIAL ステージ」, a 45-minute window inside the wider main-event stream block. Organizers billed the stage as delivering “world’s fastest” (世界最速) new ONE PIECE Card Game information.
For the set that released on the same weekend as ONE PIECE DAY’26, our OP-17 release date and card list guide covers the cards themselves.
How to Watch the Free Livestream from Abroad
All ONE PIECE DAY’26 stage programming streamed free on the official ONE PIECE YouTube channel, plus X and LINE — both added as live-stream platforms for the first time in 2026, alongside YouTube, which had carried the stream in past editions. No ticket, account tier, or region unlock was mentioned in the official scheduling — just the stream link when it went live.
The two streaming windows were the Premiere Eve stage segment and the main-event block, 10:30–18:30 JST. The card game stage sat inside that second window, and converted to other time zones as follows:
| Time Zone | ONE PIECE CARD GAME SPECIAL Stage (local time) |
|---|---|
| JST (Japan) | 12:40–13:25 |
| UTC | 03:40–04:25 (same day as JST) |
| US Eastern (EDT, UTC−4) | 23:40–00:25 (from the previous evening) |
| US Pacific (PDT, UTC−7) | 20:40–21:25 (previous evening) |
In other words, the stage fell right around midnight for US East Coast viewers and at about 8:40–9:25 pm for West Coast viewers. For any other region, working from the UTC line and adjusting for your own offset gives the slot, since JST doesn’t observe daylight saving and stays fixed at UTC+9 year-round.
The broader main-event window (01:30–09:30 UTC) carried the poll countdown and the other stage segments on the same three platforms.
Organizers also ran a stream-specific incentive: following @Eiichiro_Staff on X and posting with the hashtag #ONEPIECEDAY during the main-event stream entered viewers into a draw for 30 winners of event goods sets. Eligibility and prize-shipping terms for overseas entrants weren’t specified in the official materials.
The OP-17 Launch Weekend Overlap
Booster pack 「世界最強の戦士」【OP-17】 marked the ONE PIECE Card Game’s 4th anniversary.
That weekend had three things happening in parallel for card game fans: OP-17 reached shelves and official-shop events, ONE PIECE DAY’26 ran its two-day program at Makuhari Messe, and the card game stage capped things off. OP-17’s release and the stage were not tied together — the release was set independently of what aired — but the timing gave anyone following the OP-17 launch a reason to also have the main-event 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 the set’s chase cards 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. Our Japanese One Piece booster box lineup ships from Tokyo.
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-」 went on lottery sale through Premium Bandai starting August 22, and organizers specifically noted it was 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 included 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 had 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. Sourcing requests for past ONE PIECE DAY promos or other Japanese One Piece singles go through Quick Order.
The ONE PIECE DAY’25 Precedent
The useful comparison is what happened at the previous edition. ONE PIECE DAY’25 ran August 9–10, 2025, and its card game programming is where the teaser video for booster 「受け継がれる意志」【OP-13】 was world-premiered — roughly two weeks before OP-13 itself released on August 23, 2025. The ONE PIECE DAY’26 card game segment sat inside the free stream window, so overseas collectors could watch it live rather than rely on secondhand recaps.
Where to Follow Along
For the stream itself, the official ONE PIECE YouTube channel, X, and LINE were the three confirmed platforms. On X, @Eiichiro_Staff ran the official stream and #ONEPIECEDAY campaign, while @ONEPIECE_tcg was the account for 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.
The OP-17 The World’s Strongest Warriors booster box is currently listed at ¥11,191 (~$73), and the One Piece card box collection shows the wider Japanese sealed lineup. USD figures convert at ¥154/USD, approximate.
