For generations we have mostly lived by farming the waters off Sanriku. We issue this leaflet in the hope that more people will savor our seafood products, into which we, fishermen of these cold waters, have poured our heart and soul.
The sea off Sanriku is fertile and clean, almost incomparably so in the world. Freshness is everything for marine products. It is our greatest pleasure as fishermen to provide customers with seafood taken from the sea in the early morning, with nothing added and nothing taken away.
Since our founding days we have been committed to making foodstuffs that we can proudly offer as true marine products to our valued customers. We will continue to work hard so that more people can savor the seafood from the waters off the Sanriku coast. We hope that you will continue to enjoy our products.
