Japanese Edition vs English Edition

The two prints aren't interchangeable. The Japanese print carries Lucky.Roux (OP17-033) as its Treasure Rare, while the English print puts Edward.Newgate (OP17-040) in that slot. The Japanese set also released a week earlier than English, on 22 August 2026 versus 28 August 2026.

FAQ

Is this the Japanese or English edition? This listing is the Japanese-language print. Card text, the Treasure Rare, and the release date differ from the English version described above.

Is the box sealed? Yes, each box is a factory-sealed display of 24 booster packs, straight from Bandai.

Collectors chasing the Lucky.Roux Treasure Rare or the Rocks Pirates debut, and players importing ahead of the English print, both want this box. Buy the One Piece OP-17 Booster Box (Japanese) online at GB Toys with fast Australia-wide shipping.
