Otsuka (pronounced Oh-tsu-ka) means ‘major milestone’. Our logo is comprised of two shapes that are a symbolic representation of the company’s corporate philosophy. The large blue shape, which comes from the first letter of Otsuka, represents the sky. The blue gradation signifies openness, freedom, intelligence and the future. The small ‘O’ in red is intended to represent the focused energy of Otsuka.

During this time, we have discovered and developed treatments for central nervous system disorders, cardiovascular and digestive diseases, cancer, respiratory and dermatology conditions.
