Committed to Better Health Worldwide

At Otsuka, our people are passionate about developing and delivering original products as part of a global holistic commitment to better health and well-being. We have two core businesses dedicated to achieving our goals: a pharmaceutical business and a nutraceutical business. The pharmaceutical business develops and markets products for the diagnosis and treatment of disease in the following areas: central nervous system, oncology, gastroenterology, ophthalmology and cardiovascular. The nutraceutical business is dedicated to maintaining and improving health through the use of foods and beverages that provide extra health benefits in addition to their basic nutritional value.

We are One Otsuka.

One vision, 
One common goal.
Since the beginning, nearly 100 years ago, the Otsuka family sought to develop products that stood out from the crowd, by traveling down the paths of discovery where others were less likely to tread.

Big Venture

We believe our culture and our people are the differentiators that empower us to produce breakthrough results. This is what makes us a big venture company that takes risks and focuses on unmet medical needs in order to develop new and better therapeutic compounds. We harness the extraordinary creative and innovative abilities of our people to solve problems differently, and to persevere until they find answers. We are in this for the long-haul. Otsuka is a highly ethical company. We adhere to the highest standards in how we develop and deliver our products, and in how we treat our most valuable assets: Otsuka-people. We encourage them to follow their dreams, as turning dreams into reality is at the core of everything we do. It paves the way ahead to achieve our shared purpose: impacting on human health to help people live better lives. 
"As a total healthcare company, Otsuka Pharmaceutical will continue to focus on unfulfilled needs of patients and consumers on a global scale, creating creative, innovative products and new market categories in our efforts to contribute to the health and well-being of people everywhere."
