Key facts: what is the OP-15 Japanese booster box?

It is the Japanese original edition of the 15th ONE PIECE CARD GAME booster set, sold by us as the OP-15 Island of God Japanese One Piece Booster Box. The table below gives the exact names and numbers, each taken from the official OP-15 page or from our product page.

The theme is the sky-island story. Our product page describes a set that features Enel, the Shandians and the Straw Hats in their sky-island journey, and the official page confirms Enel and Monkey.D.Luffy as the Secret Rare characters.

What is inside an OP15 booster box?

An OP15 booster box contains 24 sealed booster packs, each with 6 cards, so 144 cards in total. Those cards are drawn from the 125+1 card types listed on the official page for the set, and the packing is random, so the product page states that individual card pulls are not guaranteed.

The 125+1 figure is the number of different cards in the set, not the number in your box. The table below splits it by rarity, using the breakdown printed on the official OP-15 page.

Two practical points follow from this table. First, the Common, Uncommon and Rare rows hold 101 of the 125 types, so the bulk of the set by type count sits in those rarities. Second, the official page notes that multiples of one card may appear and that completing a full set may be difficult. Plan on duplicates if you open a box.

The official card list for OP-15 shows 152 results, which is a larger number than 125+1. Its rarity codes are L (Leader), SR, R, UC, C and SEC. Use 125+1 when you want to know how many card types the booster set has, and use the card list when you want to look up a specific number or an alternate version.

Our own product page text lists 8 Leader Cards, while the official page lists 6 Leader Cards, which matches the six new Leaders named on the official page. Go with the official figure of 6.

Which cards headline the OP-15 set?

The headline cards of OP-15 are its six new Leaders, the two Secret Rares OP15-118 Enel and OP15-119 Monkey.D.Luffy, and the Super Rares highlighted on the official product page. The official page names the Leaders and the Secret Rares directly, so you can learn the set without a third-party list.

The six new Leaders are shown in the table below, from the official OP-15 card list.

Beyond the Leaders, the Super Rare list on the official card list reads: OP15-007 Gin, OP15-008 Krieg, OP15-032 Brook, OP15-046 Sabo, OP15-053 Rebecca, OP15-060 Enel, OP15-078 Mamaragan, OP15-086 Nami, OP15-113 Roronoa Zoro and OP15-114 Wyper. That is the 10 Super Rares in the breakdown above. The product page also highlights OP15-042 Kyros, OP15-056 Would You Let Me Eat the Flame-Flame Fruit? and OP15-092 Monkey.D.Luffy.

The Secret Rares

The two Secret Rares are OP15-118 Enel and OP15-119 Monkey.D.Luffy. OP15-118 Enel is also the set’s super alternate-art card, as stated on the official page. The page lists two alternate-art Event cards as well: OP15-077 Lightning Dragon and OP15-116 Gum-Gum Golden Rifle.

If you want to read about one character in depth, our guides cover Enel in OP15 (OP15-058, 060 and 118), Luffy in OP15 (OP15-051, 092, 098 and 119) and Gin (OP15-007).

Which OP-15 cards had the illustration error?

Six cards were affected: OP15-005 Cabaji, OP15-013 Pincers, OP15-015 Higuma, OP15-017 Morgan, OP15-018 Mohji and OP15-104 Conis. An apology notice on the official site, dated February 27, 2026, explains that a production oversight caused two versions of each, the incorrect and the correct illustration, to be packaged.

The official notice lists what differed on each card, and the table repeats it.

The notice states there are no replacements for the error cards, and that future production and announcements use the correct illustrations. If you collect by illustration, compare your card with the differences in the table above.

Our longer write-up on this topic is the OP-15 Adventure on Kami’s Island guide to Secret Rares, box contents and error cards.

Which OP15 booster box listings do we carry?

We list three OP-15 items you can buy from Tokyo: the regular sealed booster box, a discounted damaged box, and a PSA 10 graded Monkey.D.Luffy L-P card. All three are in stock on our site.

The regular box

The regular box is the one to pick if you want a sealed product with an undamaged outer box. Our page describes it as brand new and sealed, shipped from our warehouse in Tokyo by FedEx, and it repeats the key point that the contents are randomized at the factory. The Japanese release date on the page is February 28, 2026, the same date as the official page.

The damaged box

The damaged box is the same OP-15 product with cosmetic damage to the outer box, such as dents or scratches, and our page says the cards inside are unaffected. The photos on that page are samples: the first image shows the regular product so you can identify the set, and the later condition photos show the typical level of damage from the same stock. The box you receive may differ from the photos.

The page is firm about the terms. The item is sold as-is, we do not respond to inquiries about it, and returns and refunds are not accepted. Read that before you add it to your cart.

The PSA 10 Luffy

The PSA 10 listing is a graded single, the OP-15-098 Monkey.D.Luffy in its L-P version, graded PSA 10 (Gem Mint). The listing warns that the PSA case may have minor scratches or marks on its surface. It is the choice for a buyer who wants one specific card in a slab instead of a random box.

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

Should I buy the regular OP15 box or the damaged box?

Buy the regular box if the outer box matters to you or you plan to display or gift it. Choose the damaged box if you only care about the packs inside and accept that the outer box has dents, creases or scuffs.

The decision comes down to four checks, based on what the two product pages say.

A simple rule works for most collectors. If you are buying for sealed collecting or a gift, go with the regular box. If you are buying to open the packs and play or sort cards, the damaged box page says the cards inside are unaffected, so only the outer box differs.

Open the damaged box listing and read the sample condition photos and the as-is terms in full before ordering, because the item cannot be returned.

How does the Japanese OP-15 box differ from the OP15-EB04 pack?

The Japanese OP-15 box is the original Japanese edition released on February 28, 2026, while OP15-EB04 is a separate booster pack page on the English official site, with the same Adventure on KAMI’s Island title, listed as available April 3, 2026. They share the Secret Rares, but their card counts differ.

That page, BOOSTER PACK -ADVENTURE ON KAMI’S ISLAND- [OP15-EB04], states a release of April 3, 2026, a price of USD $4.99 per pack (MSRP) and 159+1 types in total, including a Treasure Rare. The Japanese page lists 125+1 types and no Treasure Rare.

The OP15-EB04 page adds a rules note: cards become tournament legal 7 days after the release date in your region, and are legal from the pre-release date at a local game store. If you play, check that rule for the version you hold.

Choose the Japanese box if you want the Japanese original edition that we ship. OP15-EB04 is a different product and is not part of our OP-15 listings.

How do shipping and payment work for an OP15 booster box order?

We ship from Tokyo by FedEx with a tracking number, and most orders are processed and shipped within 5 business days after PayPal or Wise payment has cleared. Shipping cost is calculated automatically at checkout from your delivery address.

Two service levels are offered, both described on our shipping policy page.

Those transit times are estimates only. They do not include our handling time, weekends, Japanese national holidays, customs processing, carrier congestion, weather or destination-country conditions. There is no minimum order amount or quantity, so a single box is a valid order.

Address and customs points

FedEx cannot deliver to P.O. Boxes, so give a physical address at checkout. While an order is paid and its shipment is not yet scheduled, you can update the shipping address yourself in My Account, but the destination country cannot be changed. Once a shipment has been handed to FedEx, customs inspections, import procedures and other carrier events are outside our control and do not by themselves create a right to cancel or refund after dispatch.

Payment

All payments are made in Japanese yen (JPY), and the payment methods page lists the options. Wise bank transfer carries no payment processing fee, and PayPal and card payments carry a 5% payment processing fee. Cards go through PayPal’s window and the accepted brands are Visa, Mastercard, American Express and JCB, with the offer depending on your country and card.

For a Wise payment, enter the reference SST-{order number} exactly as issued. For SWIFT transfers, a receiving fee of JPY 611 is deducted before the funds reach us, and the page asks you to add that amount to your total.

Should I open an OP15 booster box or buy singles?

Open the box if you enjoy the randomness and want packs; buy a graded card if you want one named card. A booster box is a sealed, randomized product, so the contents cannot be chosen.

The set structure tells you how to think about this. A box gives you 144 cards from 125+1 types, the official page warns that multiples of one card may appear, and the set has just 2 Secret Rares. If a single card such as OP15-119 Monkey.D.Luffy or OP15-118 Enel is the goal, a box is a poor route to one specific card because the product page promises no individual pulls.

Use this short checklist before ordering:

• Want packs to open or a sealed collectible: the regular box.
• Want packs and accept outer-box wear: the damaged box, knowing it is as-is with no returns.
• Want a specific Leader in a slab: the PSA 10 OP15-098 Monkey.D.Luffy listing.
• Want the OP15-EB04 pack: it is a different product from our Japanese box, which is the Japanese edition.

We do not give pull-rate numbers or value forecasts, because neither the official pages nor our product pages state them.

A quick buying routine

First, decide between a random box and a named card. Second, if you want the box, decide on regular or damaged using the table above. Third, check the shipping service and payment method that suit you: Wise avoids the 5% processing fee, and Expedited shipping gives the shorter estimated transit window. Fourth, confirm your address is a physical one, because FedEx cannot deliver to P.O. Boxes.

Stock for sealed Japanese trading card products changes often, and the shipping policy says dispatch can take longer in some cases, for example when supplier allocation changes or a unit reserved for your order fails quality inspection. If dispatch is delayed, we contact you by email with a revised estimate.
