  • Multi-billion dollar, top-tier pharmaceutical company with dual head offices in Tokyo and Osaka, Japan
  • ~7,000 employees worldwide
  • Diverse commercial portfolio of pharmaceutical, animal health and food and specialty products
  • Strong research and development presence in the areas of CNS, inflammation/allergy, diabetes and cardiovascular disease
  • Sumitomo Dainippon Pharma's dedication to development. With a company history stretching back 100 years, the top-ten Tokyo-listed Sumitomo Dainippon Pharma Co., Ltd., established its foothold in the United States in 2006 as Dainippon Sumitomo Pharma America, Inc. (DSPA) and acquired Sepracor in 2009.

    Now the two organizations have become one in Sunovion.

    Like Sepracor, Sumitomo Dainippon Pharma has had a pragmatic approach to research, accelerating the process by tapping into a global network of partners and subsidiaries to find the most efficient and successful ways to develop and market new drugs.

    Sunovion inheritance. Sunovion now brings together the scientific focus, pragmatism, and dedication to research of both Sepracor and DSPA. Our new company combines entrepreneurial energy, with the willingness to take on any challenge, and always keeping the longer view in sight.

    We'll continue to develop therapies in two distinct treatment areas—central nervous system disorders and respiratory diseases, as well as explore other therapeutic areas. We will be working more and more closely with national and international partners and resources to keep a constant stream of worthwhile new drugs flowing into the pipeline. And, just as important, to keep a steady flow of effective treatments flowing out to our patients. Because we at Sunovion put our patients front and center, determined day by day to fulfill the promise of “Innovation today, healthier tomorrows.”

    • A new name for a new company, Sunovion brings together two timeless forces: the sun's life-sustaining power and the human power of innovation. Together they represent the life-affirming energy that drives our vision and inspires our people, who strive to realize that vision every day.
    • Our company symbol, the green prism, created by Sumitomo Dainippon Pharma, has long been a source of corporate pride among our colleagues in Japan. From its inception, this symbol has embodied the energy of the sun, the joy of good health, and the hope of the future.
