About Us
Source Cards is a trusted Japanese TCG supplier based in Tokyo, Japan. We specialize in authentic Pokémon, One Piece, and other trading card products, supplying collectors, retailers, and distributors worldwide. With genuine, factory-sealed products sourced directly from Japan, we’re committed to quality, reliability, and exceptional service.
Why we started Source Cards TCG
It began the way most collections do — a handful of boosters bought for fun that turned into a full binder, then a full shelf. Along the way we kept running into the same problem: it was hard to know whether a listing online was actually authentic, and harder still to find English, Japanese, and One Piece TCG product from one trustworthy source.
So we built the shop we wished existed. Every product that comes through our door is checked before it's listed, and every order is packed the way we'd want our own cards to arrive.
