January — EB-04 EGGHEAD CRISIS
The year opened on January 31 with EB-04 EGGHEAD CRISIS: ¥220 a pack, 6 cards a pack, 67 card types plus 1, built around the Egghead arc with a new Jewelry Bonney leader.[4] It is the priciest 2026 box on resale: tape-sealed boxes ask ¥17,500 and up.

EB-05 released on October 31 at ¥240 a pack, alongside the ONE PIECE HEROINES PRECIOUS BOX at ¥8,470.[1][3] Card list, chase cards and what the Precious Box contains are in our EB-05 Heroines Edition vol.2 and Precious Box guide. “1BOX分” Mercari listings are loose packs, not a taped box.
November — OP-18 The Dominance of God
OP-18 (神の支配) is the next main set: November 21, 2026, ¥240 a pack, themed on Water Seven and the God Knights (神の騎士団).[1] Pre-order boxes on Rakuten were listed from ¥15,380 on 2026-11-02. Full details: OP-18 The Dominance of God box price and release guide.
December — ST-37 and ST-38
The year closes on December 19 with two ¥1,430 start decks, ST-37 Desert Princess and the Pirates and ST-38 Baroque Works — an Alabasta pairing. Each has a 51-card deck (17 card types: 1 leader, 2 super rares, 14 commons), 10 DON!! cards, a bonus pack and a play sheet.[8] Some Rakuten pre-order listings bundle both decks, so check the quantity before comparing prices.
What About 2027? OP-19 and the Next Set
As of 2026-11-02, Bandai’s Japanese product list shows nothing dated after December 19, 2026, and no OP-19 or EB-06 page exists yet.[1] The 2026 main sets landed about three months apart (late February, late May, late August, late November), so an early-2027 booster would fit the pattern — but that is a pattern, not an announcement.
Other 2026 Collector Products
Beyond packs and decks, the “other products” list on the Japanese site adds collector sets such as the Premium Card Collection Kumamoto Special (Feb 22, ¥2,200) and Mera Mera no Mi Edition (Oct 3, ¥660).[3] Some sell through Premium Bandai or BASE SHOP with lottery or per-account rules; those sales cannot be bought for you, so look for resale listings after release.

Asks seen on 2026-11-02, with multi-box lots, loose packs and singles filtered out. The cheapest boxes in Japan today are the older 2026 sets: OP-15 and OP-16 ask about 1.4× list at the low end on Mercari, OP-17 about 1.5×. The extra boosters run higher (EB-04 near 3× list), and OP-18 pre-orders price in launch demand. For singles, our guide to cheap One Piece cards from Japan compares Mercari and shop prices.
How to Buy Japanese One Piece Boxes From the 2026 Calendar
- Step 1 — Search in Japanese: 神の支配 BOX (OP-18), 世界最強の戦士 BOX テープ付き (OP-17), 決戦の刻 BOX (OP-16), EB-05 BOX テープ付き, スタートデッキ バロックワークス.
- Step 2 — Check the seal: pick テープ付き 未開封 boxes; skip テープなし, テープカット and “1BOX分” loose packs if you want a sealed box.
- Step 3 — Order: pay the item price plus the ¥300-per-item service fee on Mercari, Rakuten and Amazon Japan. An OP-16 box at ¥8,500 comes to ¥8,800 at the first payment.
- Step 4 — Time pre-orders: OP-18 ships from shops around November 21 and the December decks around December 19; order early, and the box waits at our Tokyo warehouse.
- Step 5 — Inspect: add unboxing photos (¥500 / ¥700) or a wrong/missing-item check (¥200) to confirm the tape and corners before it ships.
- Step 6 — Consolidate and ship: combine OP-18 with the ST-37/ST-38 decks or older boxes; the first six orders consolidate free. Pay international shipping plus any Japanese domestic shipping at the second payment.
OneMall buys from Japanese marketplaces such as Mercari, Yahoo Auctions, Rakuten, Amazon Japan and Suruga-ya, and from other Japanese online stores through LinkBuy (any Japanese shop URL). Items that need a lottery entry, an invitation, a purchase limit tied to an account, Japanese identity verification or a merchant account cannot be purchased. International shipping is charged on the greater of actual weight and volumetric weight (length × width × height ÷ 5,000) of the box the warehouse uses.
Timing (estimated average): once a seller ships, items reach our Tokyo warehouse in about 3–5 business days, and parcels leave 1–3 business days after you pay for international shipping. Pre-orders ship from the Japanese shop on or just before the release date, so plan around that date rather than the day you order.
Service fees are ¥300 per item on most marketplaces; from ¥200 per item on Yahoo Auctions and LinkBuy. The first six orders consolidate free; each additional order costs ¥100. Storage is free for 90 days after arrival (30 days after consolidation). Payment is by Visa, Mastercard or PayPal, settled in USD.
US buyers: since August 29, 2025, US-bound parcels of any value go through customs and pay applicable duties, taxes and fees — the $800 de minimis exemption no longer applies. OneMall currently ships to the United States by ECMS, DHL and Japan Post EMS (DDP — declared value up to USD 2,500, duties prepaid with the shipping fee); the live quote at checkout shows which lines accept your parcel.
