Japanese One Piece Card Game OP17 The World’s Strongest Warriors Booster Box

Japanese One Piece Card Game OP17 The World’s Strongest Warriors Booster Box

This is the Japanese-language edition of OP17 The World’s Strongest Warriors, the One Piece Card Game’s 4th Anniversary booster, which released in Japan on 22 August 2026. The set is themed on Elbaph, the land of the giants, and on the Four Emperors – and it brings the Rocks Pirates onto One Piece Card Game cards for the very first time.

What’s in the Box

• 24 Japanese booster packs per booster box (a full sealed display)
• 6 cards per Japanese booster pack
• 131 + 4 card types in the set (Bandai official)
• Four DON!! card designs

Set Highlights

• Rocks Pirates debut – Rocks.D.Xebec (OP17-039) is the first Rocks Pirates Leader ever printed, arriving with Whitebeard, Big Mom, Kaido, Shiki, Wang Zhi and the rest of the crew.
• Secret Rares – Rocks.D.Xebec (OP17-118) and Loki (OP17-119), the cursed prince of Elbaph.
• New premium rarities – the Super Leader Parallel (a manga-art Luffy Leader, OP17-079) and the new Pirate Crew Super Parallel cycle introduced for the 4th anniversary.
• Manga-art parallels on the four Emperors, plus a Kaido parallel newly drawn by Keisuke Itagaki, creator of Baki.
• 10 Special Cards – anniversary reprints drawn from earlier sets.

Japanese Edition vs English Edition

The two prints are not 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, on 22 August 2026, versus 28 August 2026 for English. Looking for English cards? See the English OP17 booster box.
