Japanese 30th Celebration (M6a): launch prices and chase cards

The short version

MEGA Expansion 30th Celebration, set code M6a, is the Japanese edition of the anniversary set that launched worldwide on September 16, 2026. This guide is dated three days later, so every figure in it is a launch week price. As of mid-September 2026 only 55 of the 171 cards on the set page have a US market price. A loose booster pack is about $13.99, and the site has no price yet for the 20 pack booster box.

The early leaders are Lugia (142/103) at about $171 and Charizard (137/103) at about $164, both Classic Collection reprints. The English 30th Celebration shares many of these cards, but the mapping is partial, so this guide compares only cards it can match by name and role. Pullnomics has no Japanese pull-rate data and computes no expected value for Japanese products, so this guide covers what things cost today, not what a box returns.

What MEGA Expansion 30th Celebration is

The official product page names it Pokémon Card Game MEGA Expansion Pack "30th CELEBRATION", dates it September 16, 2026, and calls the launch a worldwide simultaneous release. TCGplayer lists the same date. A pack costs 360 yen including tax and holds 6 cards, all foil. Two slots are fixed: one of 30 Pikachu cards and one Basic Energy with artwork by YOSHIROTTEN. The page also introduces a new rarity, FUR or Futuristic Rare, carried by Mew ex and Mewtwo ex.

The product page gives no box size. The official Pokémon Center Online listing does: 7,200 yen for a box of 20 packs, 120 cards, sold by lottery with a limit of one per person.

Card numbers are printed out of 103, and anything above that is a secret card. One retailer's card list, published at release, puts 20 Art Rares at 104 to 123, 10 Special Art Rares at 124 to 133, 2 Futuristic Rares at 134 and 135, and 30 Classic Collection reprints at 136 to 165. That is not an official count, but it fits the data here: the five reprints among the top cards are numbered 137, 141, 142, 150 and 165.

Bulbapedia's set page explains the English side. The international set includes cards released in the Japanese expansion and in a separate Japanese product, the 30th Celebration Premium Deck Set Espeon & Umbreon, and it is numbered out of 128. On this site the English Classic Collection has its own page, where each reprint keeps its original card number, such as Charizard #4 and Magikarp #203, while the Japanese reprints are numbered inside M6a. The two checklists overlap without being identical.

The numbers

These are the live figures from the set page. Each is a US TCGplayer market price for the Japanese printing, not a price in Japan.

In this launch week snapshot, 55 of 171 listings have a market price and 116 do not. The median priced card is about $15, which is not comparable with the English set's median of about 46 cents, where 158 of 161 cards are priced. The Japanese prices that exist sit at the top: 44 of the 55 are $10 or more and 8 are $50 or more. One copy of every priced card comes to about $1,537, and those eight make up about $834 of it, roughly 54 percent.

The rarity rows are incomplete too. The site's data has no rarity yet for 123 of the 171 listings, the group that holds the Classic reprints. Among labelled cards, 16 of the 18 Art Rares listed so far are priced, averaging about $20, and 5 of the 7 Special Art Rares, averaging about $67. Ten listings are labelled Futuristic Rare and 3 RGB Rare, a second new rarity, and none of those 13 has a price yet. The official page names only two FUR cards, so that label is wider here than in the official description.

Chase cards

These are the eight most valuable priced cards in the set right now.

Lugia (142/103) leads at about $171, then Charizard (137/103) at about $164, the Special Art Rare Pikachu ex #127 at about $139 and Magikarp #165 at about $104. Gengar (150/103) is about $79, the Sylveon ex and Jirachi ex Special Art Rares about $66 and $62, and Shining Celebi about $50. Five of the eight are Classic Collection reprints.

The table also has gaps. Outside its Classic Collection, the English set's most valuable cards are Mew ex #152 at about $203, the Futuristic Rare Mew ex #158 at about $156 and Gengar ex #154 at about $149. No Mew ex, Mewtwo ex or Gengar ex art card is among the 15 most valuable priced Japanese cards. The table shows what has sold often enough in the US to earn a market price in three days, not a finished ranking.

Japanese versus English prices

All prices are as of mid-September 2026, in the first days of both markets.

The Classic Collection reprints match by name and by their place in the reprint block. Lugia (142/103) is about $171 in Japanese, and the English Lugia #149 about $251. Charizard (137/103) is about $164 against $179 for English #4, Magikarp #165 about $104 against $138 for #203, and Gengar (150/103) about $79 against $97 for #94. Shining Celebi runs the other way: about $50 for Japanese #141 against about $45 for English #106.

Four Special Art Rares have exactly one English Special Illustration Rare of the same name. Sylveon ex is about $66 in Japanese (#130) against about $91 in English (#153), Jirachi ex about $62 (#132) against $90 (#155), Greninja ex about $45 (#125) against $47 (#148), and Salamence ex about $25 (#133) against $27 (#156).

Pikachu ex is not treated as a matched pair. English has two Special Illustration Rares, #149 at about $93 and #150 at about $131, and the Japanese Pikachu ex #127 is about $139. The four Japanese cards above each sit 23 numbers below their English twin, which would pair #127 with English #150, but that is read from the numbering, not from comparing the artwork.

Eight of the nine matched pairs are cheaper in Japanese, by anything from about $2 to about $80. No Art Rare is compared, because none could be matched with certainty. None of this makes either language the better buy. They are separate markets, and Japanese versus English cards explains why the same artwork carries two prices.

Sealed product

The booster pack is about $13.99 on the US market, a TCGplayer figure and not a price in Japan, against an official price of 360 yen. The site has no market price for the sealed box yet.

English 30th Celebration has no booster box on this site: its packs come in Elite Trainer Boxes, booster bundles, tins and collections. A loose English pack is about $17.35, and Bulbapedia describes it as 5 cards plus a Basic Energy.

The other sealed listing is the 30th CELEBRATION FUTURISTIC BOX at about $478. Its official page gives a price of 27,500 yen and this contents list: two Pikachu ex promo cards in the FUR style, 2 coins, 12 metal damage counter dice, metal Poison and Burn markers, 64 deck sleeves, a flip deck case, a display frame, a rubber playmat, a damage counter case and a playmat case. No booster packs appear in that list. It is an accessory set with two promo cards, not a way to open packs.

What a booster box guarantees, going by the official sources: 20 packs of 6 foil cards, each with one Pikachu card and one Basic Energy. Neither official page promises any Art Rare, Special Art Rare, Futuristic Rare or Classic reprint per box, and we found no official pull rates. The sealed EV board covers English products only, and its pull rates describe English packs.

Do not judge a box by its wrap. Our resealed product guide has the background: Screen Rant reported in March 2025 that Pokémon Center stores in Japan remove the shrink wrap at sale, so a bare Japanese box is not proof of tampering. Importers' rule of thumb is that many Japanese boxes open through a cardboard tear strip that cannot be put back, so ask for a photo of it.

How to buy it

Every Japanese card and product page shows the US market price, its price history, the price that counts as 12 percent below market, and two eBay buttons. Both open eBay filtered to Buy It Now listings from US sellers whose titles say Japanese, JPN or JP, with proxies, lots and other languages excluded, sorted by price plus shipping. The first is capped at 12 percent under market on the item price and the second has no cap. Both are affiliate links. The block below opens the capped searches for this set's booster box and booster pack. Today only the pack has a market price, so only the pack appears.

The cap is on the item price, so add shipping yourself. A listing counts as below market only when the landed price is at least 12 percent under market: about $12.31 delivered for a pack. If the capped search is empty, nothing is listed below market at that moment. Use the second button to see every current price, then eBay's "Save this search" so eBay emails you new matches.

The buttons are limited to US sellers, so those listings have no import step. From sellers in Japan, a shipment of any value can now pick up import charges, so find that line at checkout before you pay.

For singles, site prices are raw Near Mint. Under the methodology, a Lightly Played copy is measured against 85 percent of market. A Near Mint Lugia (142/103) has to land near $151 to count as below market, and a Lightly Played one near $128. eBay's Authenticity Guarantee covers trading cards sold for $200 or more in the US, a line even the top card here sits under, and it never covers boxes or packs. Confirm the language from photos, front and back, and read how to spot fake cards first.

Who it suits

• Collectors who want the Classic Collection reprints numbered inside one set. English lists each under its original card number.
• People who want to open a box, which English lacks. It is 20 packs of 6 with nothing promised beyond a Pikachu and an Energy per pack.
• Anyone after one card can start from the single. No box guarantees any of the eight cards at $50 or more.
• Players should look elsewhere. Japanese cards are not legal at US Championship Series events.
• Anyone who wants settled prices will not find them yet: 116 of 171 listings have none.

Bottom line

Japanese 30th Celebration is three days old. Official sources give 6 foil cards a pack at 360 yen and 20 packs a box at 7,200 yen, and promise no rarity per box. On the US market a loose pack is about $13.99, the box has no price here yet, and only 55 of 171 cards are priced, led by Lugia (142/103) at about $171. Most matched cards are cheaper in Japanese today, but the mapping is partial and both markets are new. No expected value exists for any Japanese product. For a specific card, start from the set page or the Japanese index, use the eBay buttons there, and compare landed prices with the Japanese market price only.
