Kuge Honten, founded in 1860 in Usuki, Oita Prefecture, brews its Ichinoideto label using ingredients drawn entirely from Oita Prefecture, a commitment achieved in full since fiscal year 2021. The brewery works in close partnership with local farmers to source rice from Usuki's own fields, and its coastal setting near Bungo Channel has shaped a focus on sake that complements the region's celebrated white fish and blowfish cuisine. Under the motto the region's engine, Kuge Honten promotes a community-based circular economy that links sake production to local agriculture and culture.
