Two specialist brands. One shared foundation.
KIWAMI CARDS is an online gallery for rare Japanese trading cards. KIWAMI MATCHA is a specialist brand built around choosing matcha by its taste and the ways it can be enjoyed. Both are designed to make the differences between products clear. Japan Dopamine Center’s role is to support them with shared sourcing, inspection, commerce, inventory, fulfillment and customer care.
Each brand is responsible for customer understanding, product selection and the details that explain a product. Japan Dopamine Center’s shared remit covers commerce systems, inspection, inventory, fulfillment, customer communication and data practices. The model respects the differences between cards and matcha while carrying operating knowledge and improvements across both brands.

JAPANESE COLLECTIBLES
KIWAMI CARDS
An online gallery for rare Japanese trading cards, chosen one piece at a time. Detailed product information and video introductions will share each card’s condition, story and place within a collection—a shop for exploring your collecting interests and finding a piece to treasure.
JAPANESE MATCHA
KIWAMI MATCHA
An online specialist in fine Japanese matcha, selected through flavour and aroma. Tastings and preparation videos will help you discover your cup. From a single purchase to regular orders of a favourite, the shop will bring matcha into your daily rhythm.
A card’s edition and condition, a matcha’s taste and aroma. Define the details that matter for each brand, and make clear what has been checked and what we can explain.
Language, payment, delivery and import conditions can complicate a purchase across borders. Clear information and guidance belong in the design, before and after a purchase.
Treat preparation, storage and collection care as part of the experience. Practical information and a way to learn from customer questions belong in the design.
