## History

Hisamitsu Pharmaceutical was founded in 1847 under the name Komatsuya. It was established in Tosu, which is now in Saga Prefecture, on the island of Kyushu. This region is well known in Japan for its tradition of herbal medicines.
The prototype of Hisamitsu's Salonpas patch was created in 1903 through the application of asahi mankinko, a poultice consisting of rubbing ointment pasted onto Japanese paper. The product line developed from this traditional remedy was introduced in 1934 and first exported to overseas markets in 1937.
A subsidiary branch was opened in Taiwan in 1960. In 1975 a joint company was established in Indonesia (PT Hisamitsu Pharma Indonesia). More subsidiaries followed in Brazil (Hisamitsu Farmaceutica do Brasil Ltda.) in 1986, in Singapore (Hisamitsu Pharmaceutical Singapore Pte. Ltd.) and in the United States (Hisamitsu America, Inc.) in 1987. Hisamitsu Vietnam Pharmaceutical Co., Ltd. was established in Vietnam in 1994. In 1998 Hisamitsu U.K. opened in London and a research laboratory was established in California.
In 1965 the company changed its name to Hisamitsu Pharmaceutical Co., Ltd., and in 1972 it was listed on the first section of the Tokyo Stock Exchange. The company began manufacturing and marketing prescription drugs during the 1970s. In 1988, it launched Mohrus, and in 1995, Mohrus-Tape, both prescription external anti-inflammatory drugs. Salonpas Pain Relief Patch and Salonpas Arthritis Pain were approved for over the counter sales in the United States in 2008. In 2009, Hisamitsu acquired Noven Pharmaceuticals, a specialty prescription drug transdermal pharmaceutical company based in Florida.
