A collection worth pursuing. A cup worth making your own. Through KIWAMI CARDS and KIWAMI MATCHA, we build Japanese specialist brands for a global audience.
Our BrandsSERVICES
Two specialist brands dedicated to Japanese trading cards and matcha. Thoughtfully selected products will meet visual storytelling that shares their context and ways to enjoy them. Across borders, we bring the discovery of a new passion and the time to deepen it.
JAPANESE COLLECTIBLES
KIWAMI CARDS
An online gallery for collectors of rare Japanese trading cards. We aim to bring each card’s condition and story into focus through thoughtful descriptions and video, helping collectors choose with understanding. The pleasure extends beyond finding a piece to collecting, admiring and caring for it.

JAPANESE MATCHA
KIWAMI MATCHA
A specialist in fine Japanese matcha, chosen through taste, aroma and the ways you enjoy it. Through tastings and videos on preparation, we aim to help you find your cup, with a future experience that connects individual purchases to regular orders of a matcha you love.
Brand imagery.
Dopamine is a neurotransmitter involved in reward prediction, learning and motivation. To us, the word also represents a human ambition: to imagine a possibility that does not yet exist, and act to bring it closer.
The more we learn, the more there is to ask. Studying a card or exploring a cup of matcha can open up an entire world. We build brands worthy of that lasting pursuit—experiences that give an interest room to grow.
Our StoryAssessing a card’s condition and describing a matcha’s flavor call for different expertise. Each KIWAMI brand develops its own knowledge, selection criteria and way of explaining what makes a product worth choosing.
JPDC connects sourcing, inspection, cross-border commerce, fulfillment and customer care. This shared operational foundation turns specialist knowledge into a brand that can serve people around the world.
Our BrandsBuild trusted global brands from Japan’s specialist expertise.
A world where there is always something worth looking forward to.
The science behind dopamine and the intention behind our name are distinct. Understanding that distinction helps explain how we choose to build brands.
Provenance, specifications, condition and the limits of what has been checked. Trust depends on useful evidence, not a reassuring adjective.
