One Piece – OP-17 “The World's Strongest Warriors” Japanese Booster Box Case (12 Boxes)

This is a preorder. It will be shipped as soon as it arrives from Japan — last week of August or first week of September.

The One Piece Card Game OP-17 "The World's Strongest Warriors" (set code: OP-17) is Bandai's 4th Anniversary Booster Pack, releasing worldwide on August 28, 2026. This listing is a full sealed case of the Japanese-language version — 12 factory-sealed booster boxes. OP-17 is notable as Bandai's first Global Simultaneous Release for the game: the Japanese and English versions launch on the very same day, so buying Japanese here is about the language and card art, not the early-access edge that Japanese boxes usually offer over earlier sets.

Themed around the road toward the Four Emperors and the new island of Elbaf, OP-17 spotlights legendary fighters and powerhouse warriors from across the One Piece story as part of the game's 4th anniversary celebrations. Bandai has confirmed 131 new cards plus 4 additional card types in the set — the full rarity and Leader breakdown will be confirmed closer to release, as is typical for anniversary sets, which have historically carried the game's most premium card treatments.

For players, OP-17 also marks the moment the competitive format shifts to same-day worldwide legality — no more waiting for cards already active in Japan. A full case gives shops, group breaks, and serious collectors guaranteed unopened supply of one of the most anticipated sets in the game's four-year history.
