Asanuma Corporation Teams Up With Asai Germanium Laboratory

Asanuma Corporation, a prominent ODM/OEM cosmetics manufacturer located in Nakano, Tokyo, announced a strategic partnership with Asai Germanium Laboratory, based in Kawasaki, Kanagawa. This collaboration involves the exclusive rights to sell a unique ingredient developed by Asai Germanium Laboratory, known as Repagermanium (complete ingredient label: Repagermanium). Asanuma will serve as the sole distributor of this innovative ingredient within the fields of cosmetics and quasi-drugs, strengthening its ODM/OEM operations and expanding its presence in the B2B market.

The Background of the Collaboration

Repagermanium is sourced from organic germanium, a compound extensively researched by Dr. Kazuhiko Asai, the founder of Asai Germanium Laboratory. Since the late 1950s, Dr. Asai has dedicated his efforts to exploring high-purity products suitable for food applications. Currently, organic germanium is primarily utilized in the health food sector.

Asai Germanium Laboratory is renowned for its advanced expertise and technology in the production of organic germanium. The cosmetic ingredient Repagermanium, synthesized using their proprietary techniques, promises to be a high-safety, next-generation raw material, capitalizing on the trend of incorporating components that originated from the medical field into cosmetics. Its notable anti-inflammatory and cell-activating properties are poised to attract significant attention in the industry.

Future Prospects

Under this partnership, Asanuma Corporation aims to enhance its product development, manufacturing, and supply chain capabilities utilizing Repagermanium. By merging its decades of ODM/OEM experience with a well-established customer network, Asanuma is committed to creating new value and expanding its business in the cosmetics and quasi-drugs market. The company also intends to engage in the B2B sales of Repagermanium itself, striving to boost its visibility and market penetration.
