By 2026, the One Piece Card Game has reached a decisive phase.
What began as a fast-growing competitive TCG has evolved into a structured collector market, where historical releases, premium products, and anniversary items start to define long-term value.

For collectors focused on Japanese releases, the opportunity in 2026 is clear:
combine core booster sets, market-defining expansions, and premium boxed products that were once easy to ignore — but rarely stay that way.

This article highlights the most relevant Japanese One Piece TCG products to buy in 2026, including booster sets, premium anniversary collections, and official binders.

🥇 OP-01 Romance Dawn — The Absolute Foundation

Release: 2022

OP-01 Romance Dawn remains the unquestionable cornerstone of the One Piece Card Game.

Why OP-01 is non-negotiable:

• First booster set in OPCG history

• Introduction of the game’s identity, leaders, and mechanics

• Early print runs compared to current global demand

• Permanent historical reference

As with all origin sets, sealed OP-01 will always be relevant, regardless of future releases.

💎 OP-05 Awakening of the New Era — The Manga Rare Revolution

Release: 2023

OP-05 represents the moment when One Piece TCG became a true collector’s game.

Why OP-05 changed everything:

• Introduction of Manga Rare chase cards

• Shift toward grading, display, and sealed investing

• Global collector crossover from Pokémon and Yu-Gi-Oh!

Any serious long-term collection needs exposure to OP-05, whether sealed or via key cards.

⚡ OP-09 — The Modern Stabilizer Set

Release: 2024

OP-09 represents a key stabilization point in the One Piece Card Game’s evolution.
It arrives at a moment where the player base is large, the collector base is established, and the market is no longer purely speculative.

Why OP-09 matters on its own:

• Strong balance between competitive relevance and collector appeal

• Mature rarity structure with consistent demand

• High-quality artwork across the set

• Still reasonably priced in 2026 relative to its position in the game’s lifecycle

OP-09 is not a “flash” set — it is a reliable accumulation set, the kind collectors quietly buy in quantity before scarcity takes effect.

Collector profile:
✔ Low volatility
✔ Strong fundamentals
✔ Ideal long-term accumulation

🔥 OP-13 — The Quiet Heavyweight

Release: 2025

OP-13 is fundamentally different from OP-09 in behavior and perception.
While OP-09 benefits from stability, OP-13 benefits from being underestimated.

Why OP-13 deserves its own spotlight:

• Deep and diverse character pool

• Strong overlap between playability and collectibility

• Consistent, high-level artwork

• Less initial hype, which historically favors long-term growth

These are the exact characteristics shared by many sets that later surprise the market once sealed supply dries up.

OP-13 is a patience play — and patience is often rewarded in TCG collecting.

Collector profile:
✔ Undervalued relative to content
✔ Strong long-term upside
✔ Ideal for collectors with a multi-year horizon

🎁 PRB-01 — Premium Rarity Box with Low Exposure

Release: 2024

PRB-01 is a non-standard premium product that many casual collectors skipped.

Why PRB-01 is important:

• Unique structure outside main booster lines

• Lower visibility, lower supply

• Strong sealed collector appeal

Products like this often become difficult to source years later.

📦 EB-03 & EB-04 — Expansion Boxes as Silent Performers

Expansion Boxes rarely generate hype — and that’s exactly why they deserve attention.

Why EB products age well:

• Focused card lists

• Often contain exclusive or semi-exclusive cards

• Lower print pressure compared to mainline sets

EB-03 and EB-04 fit perfectly into a long-term sealed strategy.

👑 Four Emperors Collection — Prestige Packaging, Prestige Theme

The Four Emperors (Yonko) represent one of the most iconic concepts in One Piece.

Why this box matters:

• Strong narrative symbolism

• Premium presentation

• Collector-first product design

Historically, themed prestige boxes tied to core lore age extremely well.

🎉 Anniversary Collections — 1st, 2nd & 3rd Anniversary

Anniversary products behave differently from standard releases.

Why Anniversary Collections matter:

• Limited celebratory print runs

• Exclusive promo cards

• Strong emotional and historical value

• Clear “time marker” within the game’s lifecycle

The 1st Anniversary already holds historical weight.
The 2nd and 3rd Anniversary collections continue building that legacy.

These boxes are classic long-term holds, especially sealed.

📘 Official One Piece TCG Binders — The Sleeper Category

Binders are often overlooked — until they aren’t.

Why Japanese binders deserve attention:

• Often include exclusive promo cards

• Limited reprints over time

• Appeal to display-focused collectors

• Frequently discarded or damaged, reducing long-term supply

Well-preserved sealed binders are surprisingly scarce years later.

🚀 OP-15 — The Next Unavoidable Release

Release: 2026

OP-15 is already positioned as the next essential mainline release, with:

• Strong narrative focus (Sky Island era)

• New leaders and mechanics

• Release at a mature stage of the TCG

Early sealed acquisition of OP-15 will likely be crucial for collectors looking ahead 5–10 years.
