ONE PIECE ST-37 & ST-38 Baroque Works Start Decks: Dec 19, ¥1,320

You saw the Alabasta and Baroque Works start decks on the Japanese site and want to know what is in them and whether it is worth importing one. ST-37 and ST-38 both release in Japan on December 19, 2026 at ¥1,320 each, and both contain a fixed 51-card deck, 10 DON!! cards, one bonus pack and a play sheet. An English edition of both is already listed on the official English site, which changes the import math for anyone who only wants to play.

When do ST-37 and ST-38 come out, and what do they cost?

Saturday, December 19, 2026 in Japan, at a suggested retail price of ¥1,320 each, tax included. The two decks have identical contents and rarity breakdowns. Only the characters and colors differ. All figures below come from the official Japanese product pages, checked October 21, 2026.

The official pitch lines are short. ST-37 is described as a red/blue deck that attacks with a high number of moves, fought alongside Luffy. ST-38 is a blue/black deck that swaps cards in your hand and KOs the opponent’s characters, aimed squarely at Baroque Works fans. Neither Japanese product page names the Leader card, so we are not guessing which character it is. For the bigger December picture, the release calendar lists both decks next to the rest of Japan’s schedule.

What’s actually inside each deck

Each box is a complete deck plus what you need for a first game: 51 cards, 10 DON!!, one bonus pack and a paper play sheet. The Japanese page notes that, by the nature of the product, the deck contains several copies of the same card. That is why 51 cards come from only 17 kinds.

The bonus pack is the one detail that differs by language. The Japanese pages say one pack drawn from 17 kinds and do not state how many cards each Japanese pack holds. The English pages list “Bonus Pack x 1 (3 cards)”. We are not assuming the Japanese pack matches. The official card list for these decks was not readable in a quick check, so card names, including the two Super Rares, are not covered here until Bandai publishes them.

Start deck vs booster: why there’s no pull risk

A start deck is a fixed product. You pay ¥1,320 and get the exact list on the box. A booster is random: the OP-18 booster covered in our OP-18 The Dominance of God guide sells at ¥240 for 6 cards, and what you open is luck.

For an overseas buyer, that predictability is the whole appeal. You can decide from the product page alone whether the deck is worth importing, without pricing in bad luck.

Is there an English version of ST-37 and ST-38?

Yes. The official English site lists both decks with a release date of December 18, 2026 and an MSRP of USD $16.99 each. The English contents match the Japanese structure: one 51-card constructed deck, 10 DON!! cards, a play sheet and the same 1 Leader / 2 Super Rare / 14 Common split, with a 3-card bonus pack.

Two details from the English pages are worth knowing:

1. Date check. Both English product pages say December 18, 2026. On the English products listing, checked the same day, ST-38 showed December 19, 2026. Treat the product page as the reference and confirm with your store.
2. Tournament legality. The English pages state that the cards become tournament legal 7 days after the release date in your region, and are legal from the pre-release date at your local game store.

So the question for most readers is simple. If you want to play in English-language events, the English edition is the obvious buy. Import the Japanese version only if you specifically want Japanese-language cards or the Japanese box.

The honest math on one ¥1,320 deck from overseas

Shipped alone, one ¥1,320 deck lands at several times its shelf price, because the proxy fee and postage are fixed costs that do not shrink with the item. The figures below are taken from our own fee and shipping guides; we did not weigh a deck, because the official pages do not give a weight.

The per-deck cost roughly halves once both decks share one order and one parcel. Europe is cheaper on postage (¥2,500 for the same Air Packet tier in the shipping guide), but the shape of the math is the same. The fee lines change with your proxy, your shop and how the shop charges domestic delivery, so read the fee pages before you order.

How to preorder or buy the Japanese decks from overseas

Japanese shops sell to Japanese addresses, so the route is a proxy that buys from the shop for you, then ships everything together. The official product pages link a store list (取り扱い店舗) but do not list a preorder window or purchase limit, and we have not checked individual shop stock for this article.

After release, sealed copies also turn up on eBay (paid link). Compare any listing against ¥1,320 plus the fee and postage lines above before deciding which route is cheaper for you.

If you are building a broader Japanese ONE PIECE haul, our buying guide for ONE PIECE cards from Japan covers the routes for boosters and singles, and the same consolidation logic applies: the cheaper the item, the more it pays to ship it with something else.
