One Piece Trading Card Game Explained: Sets, Products, How to Buy

Product Types: Booster Boxes, Starter Decks, Extra Boosters & Promos

Bandai’s own product listings group everything into three categories: Boosters, Decks, and Other (accessories and promo items). In practice, that breaks down into product lines you’ll see repeated across the set list:

• Booster boxes — the main numbered series, OP-01 through OP-17. Each box contains sealed packs.
• Starter decks (ST) — pre-built, ready-to-play decks aimed at new players. Bandai’s ST-31 through ST-36 wave released on 11 July 2026. See our starter decks guide for that pre-built route.
• Extra Boosters (EB) — a side series numbered separately from the main OP line (EB-01 through EB-04 as of August 27, 2026), typically built around a theme or anniversary rather than continuing the main story arc.
• Premium Boosters (PRB) — curated “best of” releases (PRB-01, PRB-02) that reprint chase cards from across multiple earlier sets in one box, aimed at collectors who don’t want to chase individual older sets.
• Promo cards — cards distributed through events, tournaments, magazines or retail campaigns rather than sold in booster boxes. These sit outside the numbered set structure entirely.

Japanese vs English Editions

The core difference that matters for buyers is timing. Japanese sets consistently release ahead of their English counterparts — OP-01 reached English shelves about four and a half months after its Japanese launch. OP-17 followed the same pattern: 22 August 2026 in Japan, 28 August 2026 in English, though the gap between recent sets has generally been narrowing compared to the game’s early years.

That timing gap is the entire reason importing sealed Japanese product makes sense for collectors and competitive players outside Japan — it lets you open a set before the English print run exists at all.

Physical card size is not published in Bandai’s own rules documentation as of August 27, 2026. Several third-party sleeve and accessory retailers report a 63×88mm footprint, the same size as Magic: The Gathering and Pokemon TCG standard cards; that is a third-party figure, not a confirmed Bandai spec.

A Starter Path: Where to Begin

If you’re new to the game, the simplest path is to learn the rules first. Our how to play the One Piece Card Game guide covers Leaders, DON!!, Life, and the basic turn structure in beginner terms — read that first if the rules are new to you.

From there, a booster box is the way to open packs of the set you want to play; the OP-17 main list includes Characters such as Haruta (OP17-009).

Once you know which characters and colours you gravitate toward, our rarest One Piece cards guide and the full OP-17 card list are useful next stops for chasing specific pulls rather than buying blind.
