Rarity symbols — the bottom right corner
Every Japanese card has a rarity symbol in the bottom-right corner of the card face. From most common to rarest: ● (common), ◆ (uncommon), ★ (rare), ★★ / H (double rare / holo rare), then the chase rarities.
For flippers the relevant rarities are: AR (Art Rare — full-art but still the base illustration style), SR (Super Rare — full-art, usually a Pokemon ex or Trainer), SAR (Special Art Rare — alternate illustration, Japanese equivalent of an EN alt-art), UR (Ultra Rare — gold/rainbow treatment), and IR (Illustration Rare — full-art regular Pokemon with no ex designation).
SAR is where the EN-JP arbitrage lives most consistently. Memorise that symbol.
Set codes — the bottom left corner
Japanese sets are identified by a short alphanumeric code: s1, sv1, sv4a, sv8a, and so on. “s” indicates Sword and Shield era; “sv” indicates Scarlet and Violet era. The number is the chronological release order within that era.
Sub-sets and sub-expansions get letter suffixes: sv4 is Ancient Roar / Future Flash, sv4a is Shiny Treasure ex. Knowing the set code lets you match the Japanese card to its English equivalent (when one exists) and price it correctly.
Card numbers — x/y format
The card number looks like 033/108 (card 33 of 108 in the base set). If the numerator exceeds the denominator (e.g., 181/108), the card is a “secret rare” beyond the standard set count.
Secret rares are always either UR, SAR, or SR — they are the chase cards of the set and command the highest premiums.
Regulation mark — the small letter
Next to the card number, you see a small letter (D, E, F, G, H). This is the format legality mark. H is current-standard as of 2026; F and G are legal in extended formats. The mark has no impact on collector value, but shop listings use it heavily for sorting.
Spotting Japanese vs Korean vs Chinese cards
Japanese Pokemon cards have Japanese text, a “Pokemon Card Game” or “ポケモンカードゲーム” wordmark on the back, and set codes starting with s or sv. Korean and Chinese cards look superficially identical — careless Western listings sometimes mix them up.
The back design is the giveaway. Japanese card backs use the iconic “Pokemon Card Game” logo in English script. Korean and Chinese backs use localised scripts. When in doubt, ask for a back photo before buying.
Condition terminology on listings
ノンプレイ (non-play) = never played, pack fresh; 美品 (beautiful) = near mint; 目立った傷なし (no noticeable damage) = lightly played; 傷あり (has damage) = moderately played or worse.
For grading submissions, only ノンプレイ or top-grade 美品 are worth sourcing. Anything less and the grading math breaks.
Glance at bottom-right (rarity), bottom-left (set code), and the number (standard or secret). Three glances and you know what you are looking at. Any Pokemon card you cannot parse in 10 seconds, skip — the listing is probably unreliable.
