OP-15 Booster Box (Japanese) — Adventure on KAMI’s Island

The One Piece Card Game OP-15 "Adventure on KAMI's Island" Japanese Booster Box (set code: OP-15) was released in Japan on February 28, 2026, with the English global edition following on April 3, 2026. This is the Japanese-language version, available approximately five weeks ahead of the English release. OP-15 is the 15th main booster expansion in the One Piece Card Game and is built entirely around the Skypiea Arc — the legendary Sky Island adventure centred on the clash between Monkey D. Luffy and "God" Enel, widely regarded as one of the most beloved arcs in the One Piece manga and anime.

OP-15 introduces six new Leader cards: Enel (Purple), Monkey D. Luffy (Sky Island variant), Krieg (from the Baratie Arc), Lucy/Sabo (Red/Blue, Dressrosa), Brook (Green/Black), and Rebecca (Blue/Black). Brook's Leader card introduces a unique game rule modification — you do not lose immediately for having zero cards in your deck, instead losing at the end of the turn your deck hits zero, enabling a distinctive mill-and-finish strategy. This is the first time a Straw Hat Crew member has debuted as a Leader card, making OP-15 historically significant for the game.

The set also incorporates the second half of Extra Booster 04: Egghead Crisis cards — specifically the Red, Black, and Yellow EB-04 cards — as part of Bandai's strategy to align Japanese and global release schedules. The first half of EB-04 was included in OP-14. Each Japanese booster box also includes one Box Topper card from multiple available variants.

The undisputed top chase card is the God Enel Manga Rare (Secret Rare SP), featuring monochromatic manga panel artwork of Enel as the ruler of Skypiea — described as one of the most visually striking Manga Rare cards ever released in the One Piece Card Game. The second most valuable chase card is the Koby Manga Rare from the EB-04 cards, making its debut in this set. The Enel Super Alt-Art and the Enel and Luffy Secret Rares round out the top chase tier. The set also includes alternate art versions of two Event cards — Lightning Dragon and Gum-Gum Golden Rifle.

The complete Japanese set contains 125 + 1 card types across the following rarities: 6 Leaders, 45 Commons, 30 Uncommons, 26 Rares, 10 Super Rares, 2 Secret Rares, 6 Special Cards, and 1 DON!! card.

Box contents: 24 booster packs per box. 6 cards per pack. 144 total cards per box. 1 Box Topper card. Language: Japanese. All card text is in Japanese. Manufacturer: Bandai. Condition: Factory sealed.

Ideal for collectors chasing the Enel Manga Rare and Koby Manga Rare, competitive players building Purple Enel or Brook mill decks, and One Piece fans of the Skypiea Arc who want the Japanese version ahead of the English release. Cards are randomised and specific pulls are not guaranteed.
