Salonpas® brand patches were first introduced in 1934 and their efficacy propelled our company to the global market leader position that we currently hold today. Salonpas® was developed through the application of Asahi Mankinko, the prototype thera...peutic patch we introduced back in 1903. The original product gained quick acceptance and was considered cutting edge technology in its day. Thanks to sustained research and input from everyday users, our products continue to evolve. Hisamitsu continues to develop and refine therapeutic patches that are safe and easy to use.
