Language is part of a card’s identity as a physical collectible. An English printing and a Japanese printing can share a card number while belonging to different releases or markets.
Search with language in mind
Check the language printed on the card and choose the matching catalog entry. Umi supports both English and Japanese catalog browsing.
Compare values carefully
A quote from one market is not automatically the value of a card from another. Condition, language, treatment, currency, and timing all affect the comparison. When the exact printing has no usable evidence, the app should say so.
