Storm Emeralda Prices in Japan: Six Weeks On, Down 63%

We priced every card in Storm Emeralda (ストームエメラルダ) at a Tokyo shop three days after release, and we said at the time that every one of those figures needed re-reading in a month. We have now re-read them. One of every single in the set cost ¥474,430 on August 3, 2026 and ¥175,670 on September 16. Same 113 cards, same shop, 63% less money. Below is the current reading first, then the launch-week one it replaced, so you can see what six weeks did.

What do Storm Emeralda cards cost now, six weeks after release?

Packs are still ¥200 for 5 cards, unchanged. Singles at yuyu-tei ran ¥30 to ¥99,800 on September 16, 2026, and all 113 cards in the set were in stock. That last clause is the story. In August, twelve cards had none on the shelf, including seven of the ten most expensive. Today there are zero.

Read the last three rows against the first two and the set splits in half. The chase cards lost two thirds of their asking price. The cheap end did not move at all, and the shop went the other way on it: it now pays ¥500 for a Talonflame ex it offered ¥300 for, ¥150 for a Heat Rotom ex it offered ¥100 for, and double for the Masquerain. Its buyback list also got longer, from 39 of the 113 cards to 45.

The launch-week reading this replaced (August 3, 2026)

Everything below was read three days after release and is kept as the record of that moment. The dates matter more than usual here, because the comparison above is the point.

How much did Storm Emeralda cards cost three days in?

Packs are ¥200 each for 5 cards. Singles at yuyu-tei (遊々亭) on August 3, 2026 ran ¥30 for a common up to ¥298,000 for the MUR Mega Rayquaza ex — but the median card in the set is ¥80, and 93 of the 113 singles the shop lists are ¥500 or less.

The number that gives you the real picture isn’t the ask. It’s the ask next to what the same shop pays to buy the card back.

All figures read from yuyu-tei’s /sell/poc/s/m06 and /buy/poc/s/m06 pages on August 3, 2026, tax included. Two card names have no published English yet: ヒガナの信頼 is a Supporter for the character localized in English as Zinnia, and ギリー is a new character with no announced English name. Rarity codes are the shop’s; if MUR, SAR and AR mean nothing to you, we broke them down in Japanese rarities explained.

The two prices every Japanese shop publishes

English-language price sources show you one number: what someone is asking. Japanese shops publish two, on mirrored pages, for thousands of cards at once — 販売 (hanbai, the shop sells to you) and 買取 (kaitori, the shop buys from you). Nothing is hidden and no account is needed. The mechanics of using those pages for any card are in how to check what a Japanese card is worth; what follows is what they said about this set, three days in.

Read down that list and one thing stands out: the spread is not constant. Cards at 60 and 61 percent sit beside a pair at 45 and one at 24. A shop closing to within 60% of its own ask is telling you it wants that card and expects to move it; a 24% offer on a ¥420 SR is telling you it has plenty and isn’t fussed. Neither number predicts anything. Both describe what a professional appraiser was willing to commit to on August 3.

The buyback list also carries direction. yuyu-tei strikes through the previous figure when it raises an offer, and on the day we checked, 20 of the 39 Storm Emeralda cards on its buyback list carried that flag — the MUR Mega Rayquaza ex among them, revised up from ¥90,000 to ¥135,000. It also stops well short of the full set: only 39 of the 113 cards it sells have any published buyback price at all. The other 74 are bulk in the shop’s eyes.

Why the highest prices are the least real

Here’s the part that cost people money in August, and the part the September reading settled. On the sell page that day, 12 of 113 cards showed 在庫 : × (out of stock) and they were not randomly distributed. Seven of the ten most expensive singles in the set had none on hand, including every Mega Rayquaza ex print above ¥1,000.

A second shop makes the point concrete. Suruga-ya (駿河屋), checked the same day, had a physical MUR 113/076 in stock, graded B on its own condition scale, at ¥153,900 — roughly half yuyu-tei’s ask for a clean copy, and close to yuyu-tei’s ¥135,000 buyback. That is not two shops disagreeing about value; it’s one price for a card in hand in imperfect condition and one price for a card that isn’t there. Suruga-ya’s condition grades and yuyu-tei’s 傷無し / 傷有り split are two different systems, and both are decoded in Japanese card condition terms explained.

One shop we could not read at all: cardrush-pokemon.jp returned 403 to every request, as it has every time we’ve researched it, so nothing from Card Rush is in this article. We’d rather tell you a source is closed than guess what it would have said.

Sealed is the only fixed price in the set

The official product page publishes one number and it does not move: ¥200 including tax, 5 cards a pack, released Friday July 31, 2026. No Basic Energy is in the set, which the official page states outright, so every card in a pack is a set card. The official page does not publish how many packs are in a box — if you see a box count quoted as official, it came from a retailer’s listing, not from The Pokémon Company.

Singles have no such anchor, and three days after release the arithmetic was stark. Buying one of every card yuyu-tei listed would have cost ¥474,430 (it is ¥175,670 now). Two cards — the MUR and SAR Mega Rayquaza ex — are ¥426,000 of that, about 90%. Strip those two out and the remaining 111 singles come to ¥48,430 together, which is roughly what 242 packs would cost you.

For the chase cards the math isn’t close in either direction — a ¥298,000 ask and a ¥200 pack are not really competing products, and which side of that you land on is about how you want to spend an evening, not about value. For everything else in the set, the singles list is a menu with the prices written on it, and we listed the chase targets by collector number when the card list dropped.

The launch-week warning, scored six weeks later

This article originally said that three days after release is the noisiest possible moment to read a card price, because supply is still arriving, the buyback side is being revised in public, and the cards carrying the biggest numbers are the ones the shop cannot supply. Six weeks of the same shop’s own list says that was right, and understated it: the set as a whole came down 63%, and the single card with the largest, most-quoted number came down 66%. Anyone who took the ¥298,000 as the market price paid for a listing, not a card.

What held up across both readings: the ¥200 pack price, the shape of the set (a handful of chase cards carrying nearly all the value, a long tail at ¥30 to ¥500), and the habit of reading the ask against the buyback instead of either one alone. What did not hold up: every chase-card figure, by half or more. That is not a failure of the August reading, it is what the August reading was telling you to expect. We will read the same two pages again.
