Who We Are
CC Group was founded with one clear objective: to give Teikoku Seiyaku a trusted, on-the-ground presence in the Americas — focused entirely on sourcing with purpose, efficiency, and integrity.
We’re not generalists. Our work is highly specialized, tailored to the unique needs of a single pharmaceutical innovator whose standards are among the highest in the industry. Every relationship we form, every material we source, and every shipment we move is part of a larger mission: to support the consistent, compliant, and high-quality production of Teikoku’s transdermal and traditional medicines.
We operate at the intersection of pharmaceutical-grade sourcing, international logistics, and supplier oversight. Our team works closely with vetted manufacturers and material producers throughout the Western Hemisphere to ensure not just availability, but trust — the kind of trust that makes global production scalable and sustainable.
Over time, we aim to strengthen this bridge between regions — streamlining complex processes, building long-term vendor partnerships, and helping Teikoku continue to deliver world-class therapies with foundations they can count on.
