Japanese cards catch English-speaking collectors out in two opposite ways. Real ones look “wrong” if you’re used to English cards, so people worry about cards that are perfectly fine. And because most of us can’t read the text, a fake is harder to spot. The light test is a good example of the first problem:
The light test isn’t really accurate and doesn’t work on Japanese cards since they are thinner than English cards. I just tested it on multiple of my Japanese cards and they all had the light shine through it

Real Japanese cards can let more light through than English ones, so a glow isn’t the red flag it would be on an English card. This page covers what else is normal on a Japanese card, the tells that do point to a fake, and how to check Chinese cards, which are now printed officially too.
What’s normal on a real Japanese card
Since July 2001, cards printed in Japan have had their own back, with more gold and yellow and a busier design than the English one, and no other language uses it. The core layer is bluish-grey rather than the black or dark grey of English cards.
The front has its own conventions too. Since the Black & White era (2010), Japanese cards have printed rarity as letters (C, U, R, RR, AR, SR, SAR, UR and others) instead of symbols. There’s a text set code next to the card number, like SV2a or S12a, and Japanese cards carried regulation marks from the Sun & Moon era on, a full series before English ones did. Numbering differs from the English sets as well. Japanese 151 runs to 210 cards and English 151 to 207, so the same card often has a different number in each language.
The back
Japanese cards have had two backs. The old “Pocket Monsters” back, used from 1996 to July 2001, reads ポケットモンスターカードゲーム (“Pocket Monsters Card Game”), with “POCKET MONSTERS” arched across the top and a copyright notice at the bottom. You’ll see it on vintage cards from the original Expansion Pack through the Neo era. The modern Japanese back arrived with the Pokémon VS set in July 2001 and is still in use.
That history gives you three quick checks. A Japanese front on an English back isn’t an official card, and nor is the reverse, with the one exception of World Championships deck cards, which have their own backs. An old back with a 1st Edition stamp doesn’t add up, because Japanese 1st Edition stamps started with Pokémon VS, the same set that brought in the new back. And on a real modern back, the blue near the top right of the Poké Ball blends several shades, where fakes tend to show one flat, lighter blue.
Tells on the front
The bottom-left strip
On modern Japanese cards the regulation mark, set code, card number and rarity letters sit together at the bottom left, and this strip is the best place to catch a fake without reading any Japanese. The rarity should fit the number: a card numbered above the set size, like 201/165, is a secret rare and should carry AR, SR, SAR or UR, not C or R. The number should be the Japanese one, not the English one, which you can confirm on the official Japanese card database. English rarity names are a warning sign too. The gold chase cards English collectors call hyper rares are marked UR on Japanese Scarlet & Violet cards. And a Japanese card from Sun & Moon onward should have a regulation mark.
Text you can compare without reading it
You don’t need to read Japanese to compare letter shapes. Pull up a scan of the real card and look at the characters side by side. Fakes tend to have fuzzy or pixelated characters, ink bleeding and uneven stroke weight, and the small print (the set code and copyright line) is often unreadable. The line work inside the energy symbols is another place cheap fakes drift.
Texture and holo
Special art rares (SAR) and art rares (AR) have a texture you can feel. Run a fingernail across a real one and you’ll feel fine ridges, while most fakes are flat and smooth. Real holo moves smoothly as you tilt it, where fakes look static, cloudy or like an oil slick. On Japanese 151, the common, uncommon and rare mirror cards have a Poké Ball pattern, or rarely a Master Ball pattern, so compare it with reference photos.
Stock and size
Japanese cards are the same size as English ones, 63 × 88 mm. Guides quote exact thicknesses and disagree with each other, so compare with a real card from the same set rather than trusting a number. Real cards are slightly glossy and firm. Fakes are often too matte, flimsy or plasticky.
Which Japanese cards get faked
Fakes follow the money: special art rares and alt arts of the big names (Charizard, Pikachu, Umbreon, Mewtwo) from high-value sets like Pokémon Card 151 and Shiny Treasure ex, plus vintage cards and promos. PSA’s 2025 data puts the 1996 Japanese Base Set Charizard and several Japanese Pikachu promos among its most-altered cards (see the Charizard and Pikachu guides). For a specific card, the Ungraded fake card database logs real and fake examples from every Japanese era.
Vintage Japanese Gold Star cards are a special case. The real ones were never sold in packs, only through the Japanese Players Club points program. Fakes show muddy color, blurry text and a printed-on sparkle instead of real foil.
Sealed Japanese boxes and packs
Factory shrink wrap on a Japanese box is tight and glossy, usually with a white Pokémon logo printed on the film and small air holes. Resealers using a heat gun rarely leave air holes, and their film tends to be stiffer and to crinkle loudly. Seams should be neat and centered, and a second, overlapping seam is a warning sign. Not every Japanese product has logo wrap, so compare with photos of the exact box. Since September 2022, Japanese booster boxes open by tearing a perforated strip along the top, so a torn or creased strip means the box has been opened. Some Japanese shops remove the shrink wrap when they sell a box. An unwrapped box isn’t necessarily fake, but there’s no telling what’s been done to it.
The barcode on the box should match the set, and several “sealed” boxes with identical lot numbers suggest repackaging. Know the pack size too: Japanese 151 packs hold 7 cards and Shiny Treasure ex high-class packs hold 10. The fake packs guide has more.
Without a real box beside you, even careful buyers struggle. This collector had two Mega Dream boxes from the same seller:
I also thought at first that #1 was fake and #2 might be real, but the printing on #2 is actually blurrier. I’m confident both are fake/repackaged since they’re from the same seller

Chinese Pokémon cards: official or fake?
“Chinese fakes” is collector slang for counterfeits made in China. It doesn’t mean every card printed in Chinese is fake. Traditional Chinese cards (for Taiwan, Hong Kong and Macau) had short runs in 2000 and 2006 and have been released regularly since October 2019. Simplified Chinese cards for mainland China have been official since 28 October 2022, starting with Storming Emergence. Pokémon cards were never officially printed in Simplified Chinese before that, so an earlier Simplified Chinese card isn’t official.
An official Simplified Chinese rare has a small Pokémon logo in a bottom corner, textured on holos, and a card that’s missing it, or has it flat or printed, is very suspect. The set code ends in “C”, like CSV1C, and the card uses the official name 宝可梦 (寶可夢 in Traditional Chinese). Older Chinese names for Pokémon never appeared on official modern cards, so a modern-looking card with an old name is a bootleg. Chinese cards use the international back, the same as English cards, not the Japanese one.
Korean, Thai and Indonesian cards are official too. An unfamiliar script isn’t a fake tell on its own. Check the logo, the set code and the print quality as you would on any card.
Buying Japanese cards
In listings, I’d be wary of stock photos, front-only shots of an expensive card, photos cropped to hide the edges, and sellers who won’t send more pictures. Prices well below Japanese market rates are a warning, and sealed product that’s “unopened yet too cheap” is the classic one.
Buying from Japan, Mercari Japan offers an authentication service (Anshin Kantei) for singles and slabs, and proxy services like Buyee let you pay for extra photos before your parcel ships. Raise any problem while the parcel is still in Japan. For graded cards, a real cert number isn’t proof on its own, since fake labels reuse real numbers. How to spot a fake PSA slab explains what to compare. For the checks that work on every card, see the main guide.
Japanese and Chinese card FAQ
Do Japanese Pokémon cards have a different back?
Yes. Since July 2001, cards printed in Japan have their own back, with more gold and yellow than the English one. Cards from 1996 to 2001 have the older “Pocket Monsters Card Game” back.
Is a Japanese card with an English back fake?
Yes. Only Japanese-printed cards use the Japanese back, so a Japanese front on an English-style back doesn’t match any official card. World Championships deck cards are the one exception.
What do the letters on Japanese cards mean?
They’re rarity codes, such as C (common), U (uncommon), R (rare), RR (double rare), AR (art rare), SR (super rare), SAR (special art rare) and UR (ultra rare). You’ll find them at the bottom left, beside the set code and number.
Does the light test work on Japanese cards?
Only roughly. Japanese cards have a bluish-grey core, and real ones can let a fair amount of light through, so compare with a real Japanese card rather than an English one.
Are Chinese Pokémon cards fake?
Not necessarily. Traditional Chinese cards have been officially released since 2019 and Simplified Chinese since October 2022. “Chinese fakes” usually means counterfeits made in China, not official Chinese-language cards.
Can an old-back Japanese card be 1st Edition?
No. Japanese 1st Edition stamps began with Pokémon VS in July 2001, the same set that introduced the new back, so an old-back card with a 1st Edition stamp doesn’t add up.
