This report is preserved as the day-one price baseline for Storm Emeralda. One week on, boxes and most secret rares have repriced — lowest box asks around ¥20,800, Mega Rayquaza ex SAR asks roughly halved to ¥65,000–88,000, while the MUR holds at ¥300,000–350,000. For the continuously updated market picture, see the Storm Emeralda buying guide (Week One Market Report).
¥298,000 for a single card — hours after the first shrink wrap came off.
Storm Emeralda (M6) hit Japanese shelves today, July 31, 2026, and the market moved fast. The Mega Rayquaza ex MUR opened at ¥348,000 on Japanese marketplaces this morning, the SAR climbed 17% before lunch, and sealed boxes are trading at roughly four times MSRP.

Storm Emeralda launched at ¥23,000–25,000 per box (~$141–$153) — about double any previous MEGA-series set — after correcting roughly 30% from its pre-release speculative peak. The Mega Rayquaza ex MUR leads singles at ¥298,000, while the SAR Mega Rayquaza and Raikou ex SAR actually rose during release day. All prices are July 31, 2026 snapshots at ¥163/USD and will move fast.
Release Day Snapshot: Storm Emeralda by the Numbers
Here’s the state of the market on launch day, at a glance:
| Metric | Release-day figure (July 31, 2026) |
|---|---|
| Box MSRP | ¥6,000 (~$37) — 30 packs × 5 cards |
| Box market price | ¥23,000–25,000 (~$141–$153) |
| Top card (Mega Rayquaza ex MUR) | ¥298,000 (~$1,830) |
| Top SAR (Mega Rayquaza ex) | ¥138,000 (~$850), up from ¥118,000 at open |
| Set size | 76-card base set + 37 secret rares = 113 cards |
| English release (Delta Reign) | November 6, 2026 — 3+ months away |
Two things stand out. First, this is the most expensive MEGA-series launch to date: previous M-series sets opened around the ¥11,000 mark, and Storm Emeralda launched at roughly double that. Second, the action is concentrated at the very top — one card, the Mega Rayquaza ex MUR, is carrying a price that would buy you twelve sealed boxes.
The rest of this report breaks down how those numbers came about, and where they might head next.
What Is Storm Emeralda? (60-Second Recap)
Storm Emeralda is the sixth expansion in the MEGA era of the Japanese Pokemon TCG, built around Mega Rayquaza ex and a Fire + Lightning energy strategy. The set introduces a new mechanic — two-part Stadium cards, led by “Legendary Summit,” which you play as a left and right pair — and features four Mega ex Pokemon: Rayquaza, Golisopod, Golurk, and Malamar.
The base set runs 76 cards, with 37 secret rares on top: 12 Art Rares, 18 Super Rares (including six Goods and special energy SRs), 6 Special Art Rares, and a single Mega Ultra Rare — Mega Rayquaza ex, card 113/076.

Box Prices on Release Day: From Pre-Release Peak to Launch
The short version: boxes are trading at ¥23,000–25,000 (~$141–$153) today, well above list price but meaningfully below the pre-release peak.
| Date | Japanese market price (sealed box) | Note |
|---|---|---|
| Early July 2026 | ~¥36,000 | Pre-release trading peak |
| July 21 | ~¥32,000 | Cooling as supply confirmed |
| July 29 | ~¥23,950 | Lowest pre-release listings (SNKRDUNK) |
| July 31 (today) | ¥23,000–25,000 | Release-day market price |

Storm Emeralda did something unusual: it was one of the most heavily pre-traded Japanese sets in recent memory. Speculators pushed sealed boxes to around ¥36,000 weeks before anyone had opened a pack — driven almost entirely by Mega Rayquaza hype. As release day approached and allocations were confirmed, that pre-release premium corrected by roughly 30%, settling into the ¥23,000–25,000 range where boxes trade now.
Even after the correction, Storm Emeralda is about twice as expensive on day 1 as previous MEGA-series sets, which opened around ¥11,000. The market is pricing this as the flagship set of the MEGA era.
Here’s the thing: a correction from a speculative peak is normal — and from a buyer’s perspective, launching below the pre-release high is a healthier entry than launching above it. What that means for timing, we cover in the outlook section below. First, the cards driving all of this.
Chase Card Values on Day 1: MUR, SAR, and AR Prices
One card dominates this set’s value, but the movement today happened across every rarity tier.
Mega Rayquaza ex MUR — 113/076
The Mega Ultra Rare Mega Rayquaza ex opened this morning around ¥348,000 (~$2,135) on Japanese marketplaces and is listing at ¥298,000 (~$1,830) as of this evening. Even after the intraday cooldown, this is among the strongest MUR debuts of the MEGA era.
First-day prices for a card this scarce are set by a handful of transactions. Expect every number on this page to swing hard in both directions over the next week — treat them as snapshots, not quotes.
Special Art Rares — the day’s biggest movers
| Card | Rarity | Opening price | Evening price (Jul 31) | USD approx. |
|---|---|---|---|---|
| Mega Rayquaza ex (110/076) | SAR | ¥118,000 | ¥138,000 ▲ | ~$850 |
| Raikou ex (108/076) | SAR | ¥11,800 | ¥16,800 ▲ | ~$103 |
| Zinnia’s Trust (112/076) | SAR | ¥10,800 | ¥9,980 | ~$61 |
| Mega Golisopod ex (107/076) | SAR | — | ¥4,480 | ~$27 |
| Mega Golurk ex (109/076) | SAR | — | ¥2,980 | ~$18 |
Prices as of July 31, 2026, Japanese shop and marketplace listings. ▲ = rose during release day.
The SAR Mega Rayquaza moving from ¥118,000 to ¥138,000 within the day is the notable story here — while the MUR cooled off its opening spike, the SAR strengthened. Collectors who missed the six-figure MUR appear to be settling on the SAR as the realistic grail of the set.
Raikou ex SAR was the sleeper of the day, up over 40% from its opening listings. Its texture-heavy artwork has been circulating on Japanese social media all afternoon, and shield-battle players want the card too, so it’s getting demand from two directions at once.
Art Rares — the legendary duo leads
| Card | Rarity | Opening price | Evening price (Jul 31) | USD approx. |
|---|---|---|---|---|
| Kyogre (080/076) | AR | ¥1,980 | ¥2,780 ▲ | ~$17 |
| Groudon (084/076) | AR | ¥1,980 | ¥2,780 ▲ | ~$17 |
| Mega Rayquaza ex (095/076) | SR | ¥6,980 | ¥7,980 ▲ | ~$49 |
Kyogre and Groudon AR climbing together is exactly what you’d expect from a Rayquaza-led set — the Hoenn weather trio sells as a themed trio, and Japanese buyers were pairing all three within hours of opening. Both ARs rose about 40% from open. For bulk-oriented buyers, ARs at this level are worth watching: the floor on legendary-Pokemon ARs in MEGA sets has held up better than generic ARs historically.
From Leaks to Launch: How Storm Emeralda Was Revealed
Today’s prices didn’t appear out of nowhere — they were built over a six-week hype cycle. Here’s how it unfolded, if you’re catching up:
| Date | Event |
|---|---|
| Mid-June 2026 | Official reveal: set name, Mega Rayquaza ex, and the two-part “Legendary Summit” Stadium mechanic announced |
| Late June–July | Card reveals roll out; leak accounts circulate early pack and card images; pre-release box trading heats up toward ¥36,000 |
| July 24 | Official full card list published — all secret rares confirmed, including the MUR |
| July 30 | Final pre-release trading day; boxes at ¥23,950 |
| July 31 | Release day — singles market goes live |
The July 24 full-list reveal was the turning point. Until then, speculation about which cards would get SAR treatment kept box prices inflated; once the list confirmed 6 SARs and a single MUR (a fairly standard secret-rare loadout), box prices compressed toward their release-day level, and attention shifted to the singles you see priced above.
One note on leak images: everything shown in this article is an official card image. During the hype cycle, unofficial early images circulated widely — they were largely accurate this time, but official confirmations are the only reveal source we treat as reliable for purchasing decisions.
Pull Rates & What a Box Actually Contains
Official pull rates are never published, so the honest answer is: estimates only. Based on opening data from the recent MEGA-series sets (Mega Symphonia, Abyss Eye), here’s what a 30-pack Storm Emeralda box is expected to yield:
| Rarity | Estimated rate |
|---|---|
| AR | ~4–5 per box |
| RR | ~6 per box |
| SR | ~2–3 per box |
| SAR | ~1 per 2–3 boxes |
| MUR | ~1 per 50–100 boxes |
Estimated from community opening data of recent MEGA sets. Not officially confirmed — treat as directional.
At a ¥23,000–25,000 box price, the value structure works like this: your guaranteed ARs and SRs provide the base return, a SAR hit (roughly one in every 2–3 boxes) is what pushes a box meaningfully into the black, and the MUR is a lottery ticket on top rather than something to price in. That’s the standard structure for modern Japanese sets — the appeal of ripping a box on release week is the shot at a ¥138,000 SAR or the ¥298,000 MUR while those prices are at their most explosive, plus sealed product from the set’s scarcest print window.
If you’re buying to hold rather than to open, the calculus is different — which brings us to what history says happens next.
What Usually Happens After Launch Day
We track every MEGA-series launch, and the pattern so far has been consistent: peak excitement in week 1, then a settling period.
- Mega Symphonia and Abyss Eye both hit their highest sealed-box prices around launch, then stabilized in the ¥9,100–14,000 range once reprint supply worked through the market.
- Storm Emeralda opened at roughly double those sets, so the market is already treating it as a different tier — but the direction of the pattern (launch heat → gradual settling as reprints land) has applied to every MEGA set so far.
- The long-term Rayquaza factor: Rayquaza-fronted products have some of the strongest aging curves in the hobby — Shining Legends boxes went from around ¥8,100 in 2021 to roughly ¥440,000 by 2026. That’s an exceptional case over five years, not a projection for this set, but it’s why collectors treat Rayquaza flagship sets differently from ordinary expansions.
So how do you play it? Three reasonable approaches, depending on what you want:
- Opening for the experience: release week is the moment — singles prices are at maximum, so hits are worth the most right now, and the community moment only happens once.
- Collecting specific cards: day-1 singles prices on mid-tier SARs and ARs often ease once opening volume floods supply in weeks 2–4. Watching the specific card you want and buying on a dip is the patient route. The exceptions today are the cards already rising against the flow — SAR Rayquaza and Raikou — where waiting has historically been the riskier side of the trade.
- Sealed holders: the question is whether Storm Emeralda follows the standard MEGA settling pattern or holds its premium the way Rayquaza-halo products historically have. Nobody knows — which is exactly why deciding your entry price in advance, rather than chasing, matters most on a set this hyped.
Whichever route you take, set your target price before you shop. Release-week markets reward buyers who decided their number in advance — and punish the ones who chase candles.

Frequently Asked Questions
How much does a Storm Emeralda booster box cost on release day?
As of July 31, 2026 (release day in Japan), sealed boxes trade at ¥23,000–25,000 (~$141–$153) on the Japanese secondary market — roughly four times list price, which is standard for a flagship Japanese set. Market price is the real price for Japanese sealed product.
What is the most valuable card in Storm Emeralda?
The Mega Rayquaza ex MUR (113/076), listing around ¥298,000 (~$1,830) on release day after opening near ¥348,000. The SAR Mega Rayquaza ex (110/076) is second at about ¥138,000 — and unlike the MUR, it rose during release day.
What are the odds of pulling the Mega Rayquaza ex MUR?
Community estimates based on recent MEGA-series sets put it around 1 in 50–100 boxes. There is no official pull-rate data, so treat all rates as estimates.
When does the English version of Storm Emeralda release?
The international version, Delta Reign, is scheduled for November 6, 2026 — more than three months after the Japanese release. Historically, Japanese-language chase cards have traded at a 15–40% premium over their English counterparts, alongside the early-access window.
Will Storm Emeralda prices drop after release day?
Previous MEGA sets peaked around launch and settled over the following weeks as supply normalized. Storm Emeralda opened at double the usual MEGA-series level, so the market is treating it as a special case — we’ll be updating this report as post-launch data comes in.
