What's PSJ

PSJ Mission

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.


The Pharmaceutical Society, founded in 1880, is one of the most distinguished academic societies in Japan. The first president of the society was Dr. Nagayoshi Nagai, Professor of Chemistry at Tokyo University, who won world acclaim for his discovery of ephedrine. Dr. Nagai said "Invent medicines, which can be easily absorbed by the body, through research on natural medicine and chemical synthesis. Then let's introduce Japanese pharmaceutical sciences to world." By following this approach, pharmaceutical sciences in Japan made a rapid progress and international contribution. Over the last 50 years, people have greatly benefited from not only improvements in diet and sanitation but also the dramatic progress in medicines. A number of medical agents have been developed in Japan and achieved worldwide recognition. Members of the Pharmaceutical Society of Japan are making major contributions in this area of pharmaceutical sciences.
