The Pharmaceutical Society of Japan aims to serve as a leading platform for pharmaceutical research in Asia and is actively promoting internationalization. This International Symposium on the 146th annual meeting of the Pharmaceutical Society of Japan has been organized with a stronger global perspective, inviting symposium speakers not only from Thailand and Taiwan but also from Germany and Canada. The symposium will focus on pharmacognosy, natural product chemistry, pharmacology, and pharmacotherapy. Each session will feature five distinguished speakers—one each from Thailand, Germany, Canada, Taiwan, and Japan—sharing their expertise to foster the exchange of international knowledge.
