Denka Seiken's mission is prevention, diagnosis, and hygiene management to support human health. We contribute to society in a variety of fields, from medicine to food and the environment.

Denka Seiken started out as a manufacturer of vaccines for human use. Later, we became involved with diagnostic reagents and expanded the scope of our business activities to meet the needs of our diverse customer base, offering our product lines, service, and in-depth knowledge to hospitals and clinics. Today, Denka Seiken has established itself as a manufacturer of vaccines and diagnostic reagents, making us unique among our many competitors in the pharmaceutical field.
Denka Seiken is engaged in diligent research and development in such fields as bacteriology and virology, immunochemistry, clinical chemistry and food-related diagnostic reagents, in addition to vaccines against influenza, DPT, and various other illnesses.
With the advent of the 21st century, we face the dawn of new challenges, such as continued health care for the elderly in a society where the average life expectancy is increasing, and the emergence of new infectious diseases, along with other environmental changes. Health-issue awareness has increased as never before. Today, our products play a diverse and crucial role in prevention, diagnosis, and hygiene management.
