Our thoughts behind our logo

Senrei is committed to using domestically produced raw materials to make available safe and reliable Japanese delicacies from Onagawa to the world.

The “S” logo, which expresses the freshness of Japanese ingredients and the sharpness of our skills, uses sharp lines in an origami (folding paper art) motif. This logo represents the aspiration of professionals from different cultures who connect and aim higher, and the sheer determination symbolic of Onagawa; in the color of the blue flame, which is hotter than the red flame.
