Itakura Sake Brewery, located in Izumo City, Shimane Prefecture, is the brewer of the sake "Tenon," and was founded in 1871. The name "Tenon" was given to the sake in 1916 by Sakamoto Gozen, the head priest of Yohoji Temple, the head temple of the Nichiren sect, which is the family's sect. Itakura Sake Brewery was named after the Buddhist phrase "Mukyo Tenon." Mukyo Tenon is a phrase that expresses the hope that if the heavens are calm, there will be no hardships (problems), and that the world and its future will be peaceful. In order to create a pure and gentle flavor like sacred sake, Tenon is brewed using the traditional Izumo brewer's technique of "San'in Ginjo sake."
