The same One Piece booster box can cost very different amounts depending on the set: on our store the OP-08 Box is listed at ¥10,719 (~$70) and the OP-05 Box at ¥59,854 (~$389). Knowing which box is which is the point of this guide.
A One Piece booster box can differ by language, set, pack format and card treatment. Japanese OP-16 and OP-17 packs hold 6 cards; check the exact product page and packaging for the box you plan to buy. OP-17 released in Japan on August 22, 2026, and the next main set, OP-18, releases in Japan on November 21, 2026.
This guide compares six boxes with the lowest SNKRDUNK asks seen on October 8, 2026 and our store listings at the time of this update, compares Japanese and English formats, and tells you which box fits which goal. We ship Japanese sealed One Piece product from Tokyo.

Japanese vs English Boxes: Formats and Card Prints
The two products share a set name and little else.
| Japanese box | English box | |
|---|---|---|
| Packs × cards | 6 cards per pack; the pack count is printed on the box | Check the exact English release and box packaging |
| Pack price | ¥220 (OP-16) to ¥240 (OP-17), official | Compare a dated listing for the exact English box |
| Release timing | First (OP-17: Aug 22) | Days to months later (OP-17: Aug 28) |
| Chase-card checklist | Check the Japanese set and exact print | Check the English set and exact print |
| Special pack configurations | Set-specific; no published pull rates | Check the specific release; do not assume identical contents |
| Tournament use | Check the event’s language and legality rules | Check the event’s language and legality rules |
Manga artwork is one reason collectors seek specific parallel prints. Compare the actual card number, language and artwork in a listing rather than assuming that every version of a set has identical contents. Bandai does not publish pull rates, so no frequency for a particular chase card is quoted here.
For a binder or display collection, the preferred artwork and language can guide the choice. For play, check the rules of the event you plan to enter. Then compare the exact box, its condition and the total purchase cost; a language label alone does not determine which product suits you.
Six Boxes Worth Buying in 2026
Store prices are the listings at the time of this update; asks are the lowest SNKRDUNK asking prices seen on October 8, 2026 (an ask is an asking price, not a sale). USD figures convert at ¥154/USD, approximate.
1. OP-17 — The World’s Strongest Warriors (newest main set)
The newest main set, released in Japan on August 22, 2026 at ¥240 per pack with 6 cards per pack (official). The OP-17 box is sold out at the time of this update; the lowest SNKRDUNK ask on October 8, 2026 was ¥11,799 (single listing, weak). The official card database lists Loki (OP17-119) as a Secret Rare and Monkey D. Luffy (OP17-079) as a Leader with two parallel prints. Full details in our OP-17 release & card list guide.
2. OP-16 — The Moment of Battle (previous main set)
Released in Japan on May 30, 2026 at ¥220 per pack (official). The OP-16 box is sold out at the time of this update — restock requests go through Quick Order. The lowest SNKRDUNK ask on October 8, 2026 was ¥9,000 (single listing, weak).
3. OP-13 — Carrying On His Will (earlier set)
For OP-13, compare the exact Japanese printing and box condition. For dated history: a launch around ¥6,000 and a market around ¥27,000 in June 2026; the lowest SNKRDUNK ask on October 8, 2026 was ¥17,999 (single listing, weak). Asks move in both directions, and a figure for one set says nothing about any other set.
4. OP-11 — A Fist of Divine Speed (listed)
The OP-11 Box option is listed at ¥35,956 (~$233) at the time of this update. The lowest SNKRDUNK ask on October 8, 2026 was ¥30,490 (single listing, weak).
5. EB-03 — Heroines Edition (the collector niche)
The extra booster built entirely around the series’ heroines. The EB-03 Box option is listed at ¥15,737 (~$102); the lowest SNKRDUNK ask on October 8, 2026 was ¥14,100 (single listing, weak). Its follow-up, ONE PIECE Heroines Edition vol.2 (EB-05), releases in Japan on October 31, 2026 at ¥240 per pack, 6 cards per pack (official).
6. OP-01 — Romance Dawn (the origin box)
The first Japanese booster set. The OP-01 Box option is listed at ¥38,901 (~$253); the lowest SNKRDUNK ask on October 8, 2026 was ¥38,000 (single listing, weak). Collectors seeking the beginning of the game can compare this set’s Japanese packaging and cards. Check the selected listing’s condition and included packaging before choosing a sealed box.
The Price Landscape Across All Sets
The table below compares store prices and availability checked on October 15, 2026 with historical lowest SNKRDUNK asks recorded on October 8, 2026. The store column names the Box option for variable products.

|---|---|---|
| OP-17 | sold out | ¥11,799 (single listing, weak) |
| OP-16 | sold out | ¥9,000 (single listing, weak) |
| OP-15 | Sourcing requests via Quick Order | no ask seen October 8, 2026 |

Three patterns worth taking from the table:
- Age alone doesn’t price a box. The OP-05 Box is listed at ¥59,854 and the OP-08 Box at ¥10,719.
- Extra boosters can list above main sets. The EB-02 Box is listed at ¥33,359 and the EB-03 Box at ¥15,737, against ¥10,719 for OP-08.
- Check the exact option before buying. The OP-08 Box option is listed at ¥10,719 (~$70). The OP-17 box is sold out, and both PRB-02 Box and Carton options are sold out at the time of this update.
Official pack prices, once for the record: OP-16 ¥220, OP-17 ¥240, and ¥240 for both OP-18 and EB-05. Per-box prices are not printed on the official pages, and packs per box are printed on the box, not on the official page.
OP-17: The Newest Box
OP-17 released in Japan on August 22, 2026 at ¥240 per pack, with 6 cards per pack (official). The OP-17 box is sold out at the time of this update; restock requests go through Quick Order.
Where things stand:
- The Japanese box is the one to open if you want the JP print and its chase tiers, which arrive before the English release.
- The English print: check the official English release information, product packaging and current event rules before choosing it for play.
- The next main set, OP-18, releases in Japan on November 21, 2026 at ¥240 per pack, 6 cards per pack (official). EB-05 (ONE PIECE Heroines Edition vol.2) releases earlier, on October 31, 2026.
Buying from Japan: Singles, Boxes, Cases
Three practical notes from the shipping side:
- Check the selected listing’s condition. Confirm the described packaging and any outer-box damage before ordering. Use the product page for the condition and terms of the exact option you select.
- Cartons are whole cases. A carton (case) is one sealed shipping case of booster boxes — sold and shipped as the whole case, not as individual boxes. Boxes per carton vary by set and are shown on each product page, and Quick Order has a CARTONS tab.
- Review the shipping options. The product page and checkout show the options and costs for the selected items and destination.
Frequently Asked Questions
How much is a One Piece booster box?
Prices vary by set. On October 15, 2026, our Box options are listed at ¥10,719 (~$70) for OP-08, ¥15,737 (~$102) for EB-03, and ¥35,956 (~$233) for OP-11. The OP-17 box is sold out. The official Japanese pack price for OP-17 is ¥240; a pack MSRP is separate from a store’s box listing.
Are Japanese One Piece boxes worth it over English?
It depends on your goal. Japanese boxes suit collectors who want Japanese-language cards and packaging; English boxes suit collectors who prefer English-language prints. For tournament play, check the event’s language and legality rules. Compare exact set contents and total cost, because Bandai does not publish pull rates.
How many packs are in a One Piece booster box?
The pack count is printed on the box, not on the official product page. What the official pages print is the pack format: Japanese packs hold 6 cards (OP-16 ¥220, OP-17 ¥240 per pack); check the exact English release and box packaging for its pack and carton configuration.
What is a God Pack?
Collectors use “God Pack” for a special pack containing multiple high-rarity cards. The contents depend on the product. Bandai does not publish pull rates, so this guide quotes no God Pack frequency.
When did OP-17 release?
OP-17 The World’s Strongest Warriors released in Japan on August 22, 2026 at ¥240 per pack, 6 cards per pack (official). The next main set, OP-18, releases in Japan on November 21, 2026, also at ¥240 per pack.
Store prices and availability were checked on October 15, 2026; asks are the lowest SNKRDUNK asking prices seen on October 8, 2026. Bandai does not publish pull rates; Manga Rare and God Pack frequencies you see elsewhere are community estimates.
