As a pharmaceutical company dedicated to research and development which challenges the unknown based on the fundamental ideals of "creativity and safety", Nippon Zoki Pharmaceutical Co., Ltd. has actively developed original drugs since its founding in 1939.

The Institute of Bio-Active Science and the Technology Research Laboratory, in particular, have an integral function in basic research on the relationship between bioactivity and pathophysiology. Through research on endogenous bio-active substances which play a vital role in protecting the homeostasis of the body and the effects pertaining to their regulatory mechanisms and cell repair function, researchers are successfully tackling the task of developing therapeutic drugs for intractable diseases.

To ensure the uniformity and high quality of our pharmaceutical products, Ono Ryokuen Factory is equipped with state-of-the-art equipment and an exhaustive quality control program is enforced. Furthermore, using know-how derived from our extensive experience in the development and manufacture of pharmaceutical drugs, we are also developing a precision machinery plant. These accomplishments are a result of our company's spirit of "honesty, creativity, and courage", our emphasis on employee-initiated self-study, and our commitment to serve society through a purposeful life - values which have been carefully nourished since the founding of Nippon Zoki Pharmaceutical Co., Ltd. With renewed determination, we will continue to advance toward the "health industry of tomorrow".
