Enoki Shuzō Brewery, founded in 1899, is in the tiny port town of Ondo-cho, Kure City, Hiroshima Prefecture. The region, Setouchi, is known for its moderate climate, with a stable year-round temperature and relatively low rainfall levels. In 1974, the brewery introduced the first Kijōshu, a sake recipe created by the National Research Institute of Brewing based on ancient sake brewing techniques. Kijōshu is currently made by fewer than 30 breweries in Japan. Kijōshu is brewed using sake instead of water in the last step (tomezoe) of a three-part brewing process.
