Japanese vs English Pokémon Sets: How Japanese Sets Become English

Collector's Edge

Almost every English Pokémon set starts life in Japan. The Pokémon Company releases a set in Japanese first, then roughly two months later the English version arrives, usually with the same cards, new card numbers and sometimes extra cards folded in from other Japanese products. Here's how that works, using the current Mega Evolution sets as examples, and why plenty of collectors buy the Japanese version too.

01 · The process

How a Japanese set becomes an English one

Japan gets each set first. The English release that follows is put together from it, and there are three common patterns.

1One Japanese set becomes one English setThe most common pattern lately. Perfect Order is nearly identical to Nihil Zero, Chaos Rising to Ninja Spinner and Pitch Black to Abyss Eye.
2Two or more Japanese products combineMega Evolution merged Japan's twin sets Mega Brave and Mega Symphonia. Phantasmal Flames added the Mega Gengar ex and Mega Diancie ex decks to Inferno X. Ascended Heroes took MEGA Dream ex plus Start Deck 100 Battle Collection.
3A worldwide set30th Celebration launched on 16 September 2026 in both Japan and English, the same day. That's rare.

Along the way a few cards usually move. A Japanese illustration rare often becomes the promo in the English Elite Trainer Box, and Gym or deck promos from Japan can be added into the English set list.

02 · Example

Worked example: Storm Emeralda becomes Delta Reign

Japan's Storm Emeralda (set code M6) came out on 31 July 2026, led by Mega Rayquaza ex, with the new two-part Legendary Stadiums. The English version is Delta Reign, out on 6 November 2026. Same headline, same artwork, but look at the numbers:

Storm Emeralda's main set is numbered to 076; Delta Reign's to 103. The extra room is for cards from elsewhere. On the same day as Storm Emeralda, Japan released three MEGA Starter Set ex decks, built around Eevee ex, Zoroark ex and Meowscarada ex, and Delta Reign is expected to take in the 30 unique cards from those decks.

04 · Differences

What changes between Japanese and English sets

Japanese English
Release First Usually 7 to 10 weeks later
Set size Smaller: Storm Emeralda's main set is numbered to 076 Often bigger: Delta Reign's is numbered to 103
Booster pack 5 cards Its own pack contents
Rarity on the card Printed as letters, such as RR Printed as star symbols
Set code M6 for Storm Emeralda DLR for Delta Reign
Extras Sold as separate decks and promos Some folded into the main set; some cards cut to become product promos

Storm Emeralda's packs also don't include any Basic Energy cards.

!Buying singlesJapanese and English are different printings with different numbers. If you're buying singles, check the set code and number match the version you want: 058/076 and 084/103 are the same Mega Rayquaza ex in two languages, not two cards.

05 · Why Japanese

Why collectors buy Japanese sets

  • You get the cards first. Two months or more ahead of English, and 14 weeks for Storm Emeralda.
  • Smaller sets are easier to finish. A main set numbered to 076 is a shorter checklist than one numbered to 103.
  • Different products. Japan sells things English doesn't get in the same form, like the separate MEGA Starter Set ex decks.
  • Five-card packs. Smaller packs, and opening a Japanese box is its own kind of fun.

The trade-off is the language: the card text is in Japanese, which matters if you want to play with them. For most people Japanese cards are for collecting, and English cards are for playing.

06 · Our take

Japanese or English: which should you buy?

Our take

If you play, buy English. The text is readable, the cards line up with the English set lists, and it's what you'll be using at a League or a prerelease.

If you collect a set, Japanese is worth a look. You get it months earlier, the checklist is shorter, and the box opening is half the fun.

Plenty of collectors do both: Japanese for the early look and the full set, English singles for the cards they want to play.

07 · FAQ
