One Piece – OP-17 “The World's Strongest Warriors” Japanese Booster Box

The One Piece Card Game OP-17 "The World's Strongest Warriors" (set code: OP-17) is Bandai's 4th Anniversary Booster Pack. 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, down from the months-long wait earlier sets required.

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.
