​Established in 1844 (Kōka 1), the company was founded by the first-generation Ōmi merchant, Morimoto Senuemon, who began brewing sake at a timber yard along the Iwata River in the castle town of Iyo (now part of Tsu City) under the Tōdō clan's domain. The company brews sake with the wish for longevity and prosperity for those who drink 'Kuromatsu Okina,' aiming to nourish the hearts and delight the souls of sake enthusiasts. They express gratitude for nature's blessings, such as the soft, round, and pure water from the Suzuka Mountains and the carefully cultivated rice from local farmers, and strive to contribute to creating a brighter world through their sake brewing.
