Founded in 1830 in Asahi, Nagaoka City, Niigata Prefecture, a region of rice paddies and satoyama. For more than 180 years since then, we have continued to brew sake with sincerity, focusing on Niigata-grown sake, using soft water from the clear underground water vein that runs through the area where the company was founded, high-quality sake rice cultivated through repeated research with local farmers, and technological innovation based on the wisdom and basic research inherited from the Koshiji Toji clan.
