Otsuka Pharmaceutical

Otsuka Pharmaceutical leverages the know-how it has cultivated in pharmaceutical business to develop products to support and maintain health in people’s daily lives. The company aims to contribute to the maintenance and improvement of health through the creation of new product categories by developing innovative products such as the electrolyte drink POCARI SWEAT, based on the concept of "a sweat replacement drink", and the balanced nutritional food Calorie Mate, which makes it easy to access the five major nutrients. In recent years, the company developed the soy bar SOYJOY, the carbonated soy beverage SOYSH and healthy soy snack SoyCarat based on the belief that soybeans, which are an integral part of Japanese food culture, could provide a solution to global health and environmental issues. Otsuka is giving the world new ways to enjoy soy, with all of its abundant nutrition. In 2014, the company launched the equol-containing food EQUELLE to promote women’s health.
