"Sendai miso," with a history and tradition of over 400 years,
      is a pride of Miyagi prefecture. 
      As a representative of "Aka miso," it continues to be widely loved and is striving 
      for further evolution in the future.
 
  
            "Sendai miso" developed as a portable ration of the Date family during 
            the Sengoku period. In 1601, Date Masamune, who built Sendai Castle, 
            formed the "KABUNAKAMA" guild and developed the local industry 
            through his colleagues. The predecessor of the Miyagi Miso Shoyu Manufactures Cooperative, the "Miso and Soy
            Sauce Nakama,
" formed the "Ichinomiya Gozenkou" at the Shiogama 
            Shrine, the greatest shrine in Oshu, and designated May 11th as the day 
            of offering. Over the course of about 400 years, the flame of tradition 
            has continued to burn brightly and persistently, fueled by the spirit 
            of those who have carried it forward to the present day.

        since 1952 to promote the inheritance and improvement of traditional "Sendai miso" and Shoyu techniques among members.Striving to study and hone the skills of our members.
