Delta Reign Japanese Version: Storm Emeralda and the 22+ Card Gap

You saw Mega Evolution series Delta Reign on the English schedule for November 6, 2026, and you want to know whether Japan already has it. Japan has had the core of it since July 31: Storm Emeralda (ストームエメラルダ), the set with the same four Mega ex. But Delta Reign is at least 22 cards bigger, and nobody official has said where those come from. Here is what lines up, what doesn’t, and what the Japanese version costs today.

What is the Japanese version of Delta Reign?

Storm Emeralda (set code m6) is the closest Japanese match, by the official pages of both sets. It is not a confirmed one-to-one copy, because Delta Reign is larger.

Pokemon.com’s Delta Reign page, checked October 24, 2026, leads with Mega Rayquaza ex and adds Mega Golurk ex, Mega Malamar ex and Mega Golisopod ex. Storm Emeralda introduced exactly those four Mega ex in Japan. The page also says “over 135 cards”. Storm Emeralda has 113 numbered cards. Neither the set page nor TPCi’s press schedule names a Japanese source set.

English sets are usually built from two or more Japanese releases (the pattern and past examples are in our JP-to-EN mapping). The four shared Mega ex make Storm Emeralda a near-certain core. The card count says it cannot be the whole set.

Where could the other 22+ cards come from?

We don’t know, and TPCi hasn’t said. The arithmetic only tells you that something else is in there.

135 minus 113 is 22, and “over 135” means at least that many cards with no Storm Emeralda number. English sets have historically drawn on a second Japanese expansion, on starter-deck cards, or both. Japan released three MEGA Starter Set ex decks on the same July 31 date as Storm Emeralda, but no official page links them to Delta Reign, so treat that as a possibility, not a finding.

Several English-language fan and shop sites describe Delta Reign as the English version of Storm Emeralda. We could not open the original reports they cite on October 24, 2026, so we are not repeating their details here.

The special-illustration line is less helpful than it looks. If TPCi means illustration rares only, Storm Emeralda supplies 18 (12 AR plus 6 SAR) against “more than 35”. If it counts every secret rare, Storm Emeralda supplies 37. The phrase on pokemon.com doesn’t say which, so we don’t draw a conclusion from it.

Mega Malamar ex (メガカラマネロex, pictured at the top of this page) is a good example of why the match matters to buyers. In Storm Emeralda it comes as the RR 048/076 and the SR 094/076, and there is no SAR Mega Malamar ex in the Japanese set (the six SARs are Mega Golisopod ex, Raikou ex, Mega Golurk ex, Mega Rayquaza ex and two Trainers). If an English Delta Reign card of it turns up with art you don’t recognize, that print may not exist in Japanese at all.

How much does Storm Emeralda cost in Japan right now?

Most singles are cheap, a handful are not, and a sealed box costs roughly twice its official price on the open market. Singles below are from our daily snapshot of yuyu-tei (遊々亭) on October 23, 2026; the box figures are from Yahoo! Shopping on October 24.

yuyu-tei listed 112 of the set’s cards that day, with a median ask of ¥80. One copy of every listed card added up to ¥125,600, and more than half of that is the two Mega Rayquaza ex at the top. The top card is the one you cannot simply buy: 113/076 was sold out, and the shop’s ¥49,000 buyback is what it pays with its own money.

For sealed, the official set page gives only the pack: ¥200 for 5 cards. The 30-pack box is ¥6,000 at Pokémon Center Online, but only through a lottery for Japanese addresses (the box price breakdown has the details). On the open market, the first Yahoo! Shopping results page on October 24, 2026 showed 19 sealed-box listings from ¥11,500 to ¥34,980, with a median of ¥19,800. The four cheapest, ¥11,500 to ¥11,760, were all labeled shrink-on. Medians on that page move with whichever listings show up (our set guide read ¥16,604 across 23 listings two days earlier), so the floor is the steadier number.

Is the Japanese version cheaper than Delta Reign?

For a specific card, Japanese is the only option until November 6, and most Storm Emeralda singles cost under ¥500. For sealed, nobody can say yet, because pokemon.com publishes no Delta Reign prices.

The pack arithmetic you can do today is on the Japanese side only. A ¥11,500 box is about ¥383 a pack, against ¥200 at the official price. Pull rates are not published for either language, so a box price is never the price of a card. If you want one named card, buy that card.

If you want to see how the overseas market prices the Japanese box, an eBay search for a Storm Emeralda Japanese booster box (paid link) shows live listings to set against the ¥11,500 floor plus your shipping. Once English preorders settle, an eBay search for a Delta Reign booster box (paid link) gives you the other side of the comparison. Compare like with like: a 30-pack Japanese box and an English box are different products with different pack counts.

Should you buy Storm Emeralda now or wait for Delta Reign?

Buy Japanese now if you want a specific Mega ex print and are happy with Japanese text. Wait if you need English cards, or if you want to see the extra 22+ cards before choosing.

Japanese singles have had almost three months to settle. The SAR Mega Rayquaza ex was ¥39,800 on September 16 in our snapshot and ¥29,800 on October 23. That is a description of where one shop has priced it, not a forecast, and we are not suggesting anyone buy cards to resell.
