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

The One Piece Card Game OP-17 "The World's Strongest Warriors" (set code: OP-17) is Bandai's 4th Anniversary Booster Pack. This listing is a full sealed case of the Japanese-language version — 12 factory-sealed booster boxes, now in stock. The Japanese edition released in Japan on August 22, 2026, with the English edition following just six days later on August 28, 2026 — the shortest Japanese-to-English gap in the game's history, so buying Japanese here is mainly about language and card art rather than the months-long early-access edge 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 is rolling out with the Japanese release, as is typical for anniversary sets, which have historically carried the game's most premium card treatments.

For players, OP-17 also narrows the usual Japanese-to-English tournament-legality gap to just six days — down from the months-long wait competitive players have faced with prior sets. 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.
