Located in Omori-machi, Oda-shi, Shimane Prefecture, the Iwami-Ginzan Silver Mine was registered as an industrial heritage site and World Heritage site in 2007. A reddish-brown mineral soil found there at the beginning of the 17th century was donated to the Shogunate as a medicinal stone called MUMYOUI. The main component of the soil was believed to be ferric oxide, but it has been elucidated that the main component is manganese dioxide. It is similar to a mineral mined in China and described in HonzoKoumoku. While the minerals are listed as having the same name, MUMYOUI, they have different properties. The reason why the two minerals were confused by being referred to with similar notations at that time is unclear. Iwami-Ginzan halted presentation of MUMYOUI to the Shogunate once in the mid-18th century and began selling it to the general public shortly afterwards. In this thesis, I
introduce the appearance of MUMYOUI from Iwami-Ginzan in functional books where it was treated as a noble medicine by the public, and used and transmitted until the end of the Tokugawa Period. In addition, it was found that the medicinal products produced in the region were developed and sold by a chief administrator, resembling processes like a modern pharmaceutical company and introduced as if the business was a community-raising project.
