The Pharmaceutical Society of Japan (PSJ) aims to promote the development of pharmaceutical sciences among its more than 20,000 members. Pharmaceutical sciences are based on physics, chemistry, biology, and a wide range of life science fields. These all contribute to the health and welfare of human beings through the creation, production, supply, and prescription of medicines. The Japanese have the longest life expectancy in the world. The 21st century will be the "life science era" in Japanese society. In response to the great public need, recognition, and expectations, the PSJ encourages its active members to make the greatest possible contributions to all the pharmaceutical sciences.
