Company.

A group built around specialist knowledge.

Japan Dopamine Center is the company behind KIWAMI CARDS and KIWAMI MATCHA. We bring the specialist knowledge of trading cards and matcha into brand development and customer experience, with a shared remit spanning sourcing, inspection, commerce, fulfillment and customer care.

Distinct expertise.
A shared operating platform.

Recognizing a card edition requires different knowledge from explaining how matcha is made. Decisions about products and customers belong with the expertise of each field.

Commerce systems, inventory, inspection, international fulfillment and customer care offer work that can be shared by both brands. The company takes responsibility for these functions, bringing procedures, data and operating lessons together.

Product specialists focus on the category and the customer. Operations specialists organize the work required to deliver. Connecting those judgments allows each brand to retain its character while benefiting from the practical capabilities of the group.

How we work.

  1. Begin with the product and customer.

    Use category knowledge in sourcing, assortment and product descriptions. Understand who needs to know what when making a decision.

  2. Make shared work repeatable.

    Organize procedures for commerce, inspection, inventory, fulfillment and customer care. Make the points that need checking clear across roles and brands.

  3. Learn from the record.

    Record decisions and their reasons, questions and operating problems, then use them to improve the work. Individual experience should become knowledge the organization can retain and use.
