A standard Japanese booster box holds 30 packs of 5 cards, which comes to 150 cards. An English booster box holds 36 packs of 10 cards for 360 in total. Japanese sets are also released first, usually around two months ahead of the English version, which often combines two Japanese sets into one bigger English set. The artwork is shared between the languages while the rarity names are different, which catches a lot of people out.
How many packs are in a Japanese booster box?
Most Japanese expansion boxes hold 30 packs with 5 cards in each pack. Special sets use their own formats. High class sets such as Mega Dream ex, Terastal Festival and Shiny Treasure ex come as 10 packs of 10 cards, while Black Bolt and White Flare boxes hold 20 packs of 7 cards each.
| Box | Packs | Cards per pack | Cards per box |
|---|---|---|---|
| Japanese expansion box | 30 | 5 | 150 |
| Japanese high class box | 10 | 10 | 100 |
| Black Bolt or White Flare box | 20 | 7 | 140 |
| 30th Celebration box | 20 | 6 | 120 |
| English booster box | 36 | 10 | 360 |
Every box on this site lists what's inside it on its own page, while the Japanese set list puts all of them in one table.
Why are Japanese packs smaller?
Japanese packs hold fewer cards and are priced to match, so the fair comparison is box against box or card against card. English packs also come with a basic Energy card and a code card for the Pokémon TCG Live app.
Which comes out first?
Japanese sets are normally released first. The English version usually follows two to three months later, often with two Japanese sets merged into a single English one. Mega Symphonia and Mega Brave came out on the same day in Japan and became one English set called Mega Evolution, in the same way Ancient Roar and Future Flash became Paradox Rift.
| Japanese set | Out in Japan | English set | Out in English |
|---|---|---|---|
| Mega Symphonia and Mega Brave | 1 August 2025 | Mega Evolution | 26 September 2025 |
| Mega Dream ex | 28 November 2025 | Ascended Heroes | 30 January 2026 |
| Abyss Eye | 22 May 2026 | Pitch Black | 17 July 2026 |
| Storm Emeralda | 31 July 2026 | Delta Reign | Due 6 November 2026 |
Some of the smaller Japanese sets never get an English release under their own name, with their cards folded into the English sets around them instead. For a collector that makes the Japanese box the only way to open those sets as they were designed.
Do Japanese and English cards use the same rarity names?
They use different labels for the same kinds of card. Japanese cards print a short letter code, so a card might be marked AR or SAR, where the English version has a name like Illustration Rare.
| Japanese code | Short for | English name |
|---|---|---|
| RR | Double Rare | Double Rare |
| AR | Art Rare | Illustration Rare |
| SR | Super Rare | Ultra Rare |
| SAR | Special Art Rare | Special Illustration Rare |
| UR | Ultra Rare | Hyper Rare |
| MUR | Mega Ultra Rare | Mega Hyper Rare |
Two of these trip people up because the words swap places. A Japanese UR is the gold card that English calls a Hyper Rare, while the English Ultra Rare is the full art card Japan marks SR. The rarity guide covers every code, the older Sword & Shield ones included.
Are Japanese cards better quality?
This part is my own view as a collector and the reason WOOPR only sells Japanese product. To me the Japanese print is a step above, which plenty of collectors would agree with. The boxes are more accessible on price as well. Japanese cards are printed on slightly thinner card stock so they feel a little lighter in the hand. They are exactly the same size as English cards at 63 by 88 millimetres, so the same sleeves, toploaders and binders fit both.
Can you play with Japanese cards?
The game itself works the same way in both languages, so Japanese cards are fine for playing at home or with friends who know the cards. Official Play! Pokémon tournaments have their own rules on card language, so check the current tournament rules before you build a deck for one out of Japanese cards.
Which should you buy?
For collecting, chasing particular artwork or opening packs for the fun of it, Japanese boxes get you the cards first and cost less to open, which is exactly why they're all we stock. If official tournament play is your main focus you'll want English cards in your deck. Plenty of people end up with both.
