The name is derived from "Jurakudai," the residence built by Toyotomi Hideyoshi, the former regent. The brewery's location (Kamigyo-ku, Kyoto City) is situated on the site of Jurakudai, and this area, as evidenced by the place name "Izumi" (meaning "water"), is blessed with abundant, high-quality groundwater. Historically, industries related to water, such as sake brewing and tea ceremony, flourished here.

We still use groundwater drawn from the same aquifer as "Ginmeisui," the water said to have been used by Sen no Rikyu for his tea ceremonies. The phrase "Rakuchu Densho" (meaning "tradition of Kyoto") embodies the spirit of our brewery, which has upheld the tradition of sake brewing in Kyoto since its founding.
