Our Two Core Businesses and Products
Otsuka-people creating new products
for better health worldwide
Helping to cure disease and protect everyday health.
Otsuka Pharmaceutical is a holistic healthcare company dedicated to the entire body.
Otsuka Pharmaceutical contributes to people's health worldwide through our two core businesses: our pharmaceutical business, focused on creating breakthrough treatments for disease, and our nutraceutical business, providing innovative products to help everyone maintain or improve their health. We recognize that good health is a universal wish, and will continue to create innovative products to help people realize that.
Providing breakthrough treatments for patients around the world
Otsuka Pharmaceutical's first drug discovery research institute opened in 1971. By choosing to tackle unaddressed medical needs, we put ourselves on the path to creating new therapeutic approaches and unprecedented drugs.
Helping healthy people
become even healthier
Starting from a solid scientific basis incorporating the expertise accumulated in our pharmaceutical business, we have developed a range of unique consumer products for the maintenance and improvement of health, and in doing so, have created entirely new markets.
We will continue to create innovative products
supporting better health for people around the world
