What are the key facts about OP-15?

OP-15 is a Japanese-edition booster set that released on February 28, 2026, with 125+1 card types and a Skypiea Arc theme. The table below gives the details that identify the set, and each one links to the page it comes from.

This guide covers the set as a whole and its rare end: the Secret Rares, the Special Cards count, the alt-art Event cards, the leaders, the error cards and how to buy. It does not repeat a full card-by-card list, because our OP-15 card list with every rarity, parallel and chase card already does that.

What are the Secret Rares in OP-15?

The Secret Rares in OP-15 are Enel (OP15-118) and Monkey.D.Luffy (OP15-119). Bandai’s official OP-15 page lists the Secret Rare count as 2, and these are the two cards it names under that heading.

Our product page for the OP-15 box describes the set the same way, naming Enel (God), Gan Fall, Wyper and the Straw Hat crew in Skypiea outfits as the key cards, and it says the Secret Rares come with alternate-art parallels.

The same two numbers appear on the English edition list. The English OP15-EB04 page shows OP15-118 as Enel (Secret Rare, Super Alt-Art) and OP15-119 as Monkey.D.Luffy (Secret Rare). So the card numbers carry across the Japanese and English editions, which matters if you search by number.

How many Secret and Special cards does OP-15 have?

OP-15 has 2 Secret Rares and 6 Special Cards among its 125 card types, plus one DON!! Card that makes the total 125+1. Those counts come straight from the rarity breakdown on Bandai’s OP-15 page.

Adding the first seven rows gives 125, and the DON!! Card is the “+1”. That arithmetic matches the “125+1 types” figure on the official page, so the breakdown is internally consistent. Secret Rare has two entries against ten Super Rares and twenty-six Rares.

These are counts of card types, not of how often a card shows up. Bandai’s page notes that multiples of one card may appear in a pack and that completing a full set can be difficult. It gives no appearance rates, and this article does not either. For box hits, see our OP-15 pull rates article.

The six Special Cards are their own line in the official breakdown, separate from the Secret Rares. A Special Card is not a Secret Rare, and a Secret Rare is not a Special Card: Bandai counts them in different rows. If you are building a want list, treat the two as separate groups.

Which OP15 Secret Rare is the Enel super alternate art?

The Enel in OP15-118 is the OP15 Secret Rare that Bandai says has a super alternate art. The official page states this for OP15-118, and the English OP15-EB04 page labels the same card Secret Rare, Super Alt-Art.

Bandai’s page also marks the Event cards Lightning Dragon (OP15-077) and Gum-Gum Golden Rifle (OP15-116) as alt-art, so OP15-118 is the Secret Rare carrying the super alternate art, while the two Events carry ordinary alt-art labels.

Enel appears several times in OP-15, so the card number is the safe way to identify this one. Bandai lists Enel as the Leader OP15-058, as a regular card at OP15-060, and as the Secret Rare at OP15-118. The English OP15-EB04 page repeats the same three numbers. If a seller lists “Enel OP-15” without a number, you could be looking at any of the three, so check for OP15-118 before you pay.

The shop’s product page names Enel (God) first among the key cards. We do not give a price view or ranking for it here, because card prices move and a printed figure would go out of date.

What is the Monkey.D.Luffy Secret Rare in OP-15?

The Monkey.D.Luffy Secret Rare is OP15-119, the second of the two Secret Rares in the set. Bandai lists it under Secret Rares next to Enel (OP15-118), and the English edition lists it as a Secret Rare too.

The official list gives Monkey.D.Luffy as the Leader OP15-098 and as the Secret Rare OP15-119. The English OP15-EB04 page also lists an OP15-092 Monkey.D.Luffy. Three Luffy numbers in the list means a “Luffy OP-15” search needs a number attached, just like Enel.

Our shop carries a graded version of the Leader, not the Secret Rare: PSA10 Monkey.D.Luffy L-P [OP-15-098]. The listing says the card is graded PSA 10 (Gem Mint), which it describes as the highest grade Professional Sports Authenticator certifies, and it warns that the PSA case may have minor scratches or marks on its surface. It also says stock levels can change and an order may take a little longer to ship.

Our shipping policy adds a note for graded cards. PSA graded cards may also be sold through our other sales channels, so an item shown online may already be sold before our team locks the allocation for your order. Once your payment has cleared, the policy says we secure the PSA graded card matching your order, even if extra sourcing is needed, and dispatch may take longer in that case.

Which other OP-15 cards sit next to the Secret Rares?

The cards that sit next to the Secret Rares are the six Leaders, the two named alt-art Event cards and a set of named regular cards. Bandai’s page counts six Special Cards but does not print their names beside that count, so this list names only the cards Bandai names.

The other cards the official page names are Gin (OP15-007), Krieg (OP15-008), Kyros (OP15-042), Sabo (OP15-046), Rebecca (OP15-053), ‘Would You Let Me Eat the Flame-Flame Fruit?’ (OP15-056), Enel (OP15-060), Nami (OP15-086) and Wyper (OP15-114). These are named cards from the set, not a complete list of it.

The two alt-art Events are worth separating from the Secret Rares. Lightning Dragon (OP15-077) and Gum-Gum Golden Rifle (OP15-116) are Event cards, so they sit in a different card category from the Secret Rare characters, and Bandai flags both as alt-art. The English OP15-EB04 page marks them the same way, as OP15-077 Lightning Dragon (Alt-Art) and OP15-116 Gum-Gum Golden Rifle (Alt-Art). For a wider look at parallels, our OP-15 parallel and SP card list goes through them.

In the named list, OP15-001 and OP15-002 are Leaders, while OP15-118 and OP15-119 are the Secret Rares. Keep those two numbers, 118 and 119, in mind when you search for the Secret Rares.

Are there error cards in OP-15 that collectors should know about?

Yes. Bandai’s notice dated February 27, 2026 reports that a production oversight packaged two versions, one incorrect and one correct, of six OP-15 cards. None of the six is a Secret Rare, but collectors tracking the set should know the list.

The official notice is an apology about an illustration error in the booster pack released February 28. It states that no replacements will be offered for the error cards and that correct illustrations will be used in future production runs. So the two versions of each of those six cards were both packaged, and Bandai does not exchange them.

This does not touch OP15-118 or OP15-119. Neither Secret Rare is on the error list. The error cards are a separate collecting question from the rarity chase, and it is cleaner to treat them that way.

How does the English edition change the OP15 Secret Rare list?

The English edition keeps the same two Secret Rares, OP15-118 Enel and OP15-119 Monkey.D.Luffy, but it is a different product with a different size. It is called BOOSTER PACK -ADVENTURE ON KAMI’S ISLAND- [OP15-EB04], released April 3, 2026, at an MSRP of USD $4.99 per pack.

The English page lists 159+1 types in total against 125+1 in Japan. The higher count and the Treasure Rare line show that the English release carries a wider card pool than the Japanese set. The English page does not list cards per pack or packs per box, so do not carry the Japanese 6-card pack or 24-pack box over to it.

The English page also gives tournament timing: cards become tournament legal 7 days after release in your region, and are legal from the pre-release date at your local game store. It links to an errata notice for card effect text. If you are choosing between the two editions for play or for collecting, our OP-15 Japanese vs English comparison goes through that choice. The short version for this article’s topic: if you want the Japanese edition of the Secret Rares, look for the Japanese OP-15 products, and check that the listing says Japanese.

What does a Japanese OP-15 box contain, and can a box give me a Secret Rare?

A Japanese OP-15 booster box contains 24 booster packs of 6 cards each, which is 144 cards in total, and no box can promise a specific card. Our OP-15 Island of God booster box page (update: currently sold out — restock requests via Quick Order) says the product is a sealed, randomized one and that individual card pulls are not guaranteed.

Read the numbers together. The set has 125+1 card types, and a box holds 144 cards. Bandai’s note that multiples of one card may appear in a pack applies, so a box is not a one-of-each set, and nothing in the official or shop pages ties a Secret Rare to any particular pack or box. Anyone who needs OP15-118 or OP15-119 for a collection should treat the box as a chance and a single card as a sure way to own that card. A sealed box is for opening the set. A single card is for owning one specific card.

We also list a Damaged Box version, OP-15 Island of God Japanese One Piece Booster Box – Damaged Box. The page explains that the discount is for cosmetic damage to the outer box, such as dents or scratches, and that the cards inside are unaffected. The photos are samples: the first image shows the regular product so you can identify the set, and the condition photos that follow show the typical level of damage. The page says the actual item may differ from the photos.

The terms matter, so read them before ordering. The damaged-box item is sold as-is, and the page states that returns and refunds are not accepted and that inquiries about the item are not answered. The same page says our warehouse in Tokyo separates boxes that fail the condition standard from regular stock and offers them at a lower price than regular products.

Where can I buy OP-15 cards from Japan, and how do shipping and payment work?

You can buy OP-15 products from our online store, which ships by FedEx. Standard shipping is FedEx International Connect Plus with tracking, and expedited shipping is FedEx International Priority with tracking, as set out in our shipping policy.

Those transit times are estimates and they start after dispatch. Most orders are processed and shipped within 5 business days after PayPal or Wise payment has cleared, which the policy also calls an estimate. Business days exclude weekends and Japanese national holidays. Shipping cost is calculated at checkout from your delivery address, and there is no minimum order amount or quantity.

Once the parcel is with FedEx, timing is controlled by the carrier and destination-country authorities. The policy lists customs inspections, import procedures, remote-area handling, peak season congestion and weather as possible causes of delay. FedEx cannot deliver to P.O. Boxes, so give a physical address at checkout. Before the shipment is scheduled you can update the shipping address yourself under My Account, then Orders, then the order. The destination country cannot be changed.

Payment is in Japanese yen. Our payment methods page lists Wise bank transfer, PayPal, and credit or debit cards through PayPal (Visa, Mastercard, American Express and JCB, with the brands offered decided by PayPal). Wise is the only method without the 5% payment processing fee; PayPal and card payments carry it. For Wise, paying by SWIFT incurs a JPY 611 receiving fee, so add that to your order total. The page also describes PayPal Pay Later, which PayPal runs, and the options differ by country.

If you are weighing a single Secret Rare against a box, the practical split is simple. For OP15-118 or OP15-119, go for the single card, because a box cannot promise either. For the Japanese set as a sealed product, use the booster box page, or the Damaged Box page if you accept the as-is terms.
