Company profile
researched Aug 2026Morus Inc. is a Japanese company working on silkworm-derived nutritional materials, developed through joint research with Shinshu University, which it describes as a leading center of silkworm research. Its core material, MorSilk Powder, is a functional ingredient made entirely from silkworms, characterized as low in fat and containing essential amino acids, 1-deoxynojirimycin (DNJ) and silk proteins, with an aroma and color said to resemble matcha. The company positions the material as addressing health and protein-supply challenges linked to disease, aging, population growth and climate change.
The business spans five activities: raw material development (MorSilk Powder); product development and sales through its own functional food brand KAIKO, oriented toward drinkable formats targeting immunity and circulation; joint research with companies and research institutions on nutritional functions, silkworm ecology and breeding, and mass-production technology and facilities; OEM manufacturing using silkworm-derived materials, with support from raw material supply through to commercialization; and corporate nutrition workshops. The company frames its work as a revival of Japan's sericulture tradition, an industry it describes as over 5,000 years old and in decline.
Business model
Morus develops a proprietary silkworm-derived ingredient and monetizes it through several channels: sale of MorSilk Powder as a raw material, direct sales of finished functional food products under the KAIKO brand, OEM manufacturing for other companies, joint research collaborations with corporate and academic partners, and paid nutrition seminars for corporate clients.
Latest developments
In July 2026 the company announced the appointment of Keisuke Muroi, was covered in Japanese media on the theme of silkworms and startups, and was featured in an article by the Singapore-based publication The Longevity Project.
