Japan Quality

Onagawa's "Delicious" to the world.

Senrei is located in Onagawa Town, Miyagi Prefecture of the Tohoku region (southern tip of the Sanriku coast on the Pacific Coast).

Senrei is located in Onagawa Town, Miyagi Prefecture of the Tohoku region (southern tip of the Sanriku coast on the Pacific Coast).

The Sanriku coast is known as an excellent fishing ground with a high catch due to the collision of “Oyashio” (cold current) and “Kuroshio” (warm current); it is called one of the world’s three biggest fishing grounds. The local Onagawa fishing port is one of Japan’s leading fishing ports with many fish landings throughout the year.

The “ria coast” of Sanriku, which spreads out similar to the shape of a saw, has many scattered islands. Many minerals constantly flow into the ocean from the forest spreading in the mountains, creating a large quantity of plankton. For this reason aquaculture is actively conducted in the nutrient-rich sea in the area.

Senrei selects high-quality items from abundant fishery resources unique to Sanriku based on a relationship of trust with fishermen and reliable selection capabilities that have cultivated over many years, and processes products to create the highest possible quality products with advanced equipment and skills of craftsmen. Its quality has been highly acclaimed not only in Japan, but also throughout Asia.


Products of Senrei

Combining advanced technology and craftsmanship, the product lineup of Senrei is built on the rich blessings of the ocean of Onagawa.
We aim to continually develop products that are fresh, delicious, safe, reliable, and easy to use.


Promoting Sanriku Onagawa’s rich ocean blessings to the world through advanced freezing processing technology.

Senrei has introduced CAS (cells alive systems) technology for frozen storage of fish and shellfish. CAS technology vibrates water molecules in a special way and prevents cell tissue from being destroyed during freezing. Using conventional refrigeration technology, ingredients such as umami drip out as the meat is thawed, but by using CAS technology, which does not damage cell membranes, frozen storage of ingredients in which freshness and umami are maintained is possible.

“Senrei CAS FRESH” is a product series recognized as “CAS FRESH,” indicating the highest quality in terms of safety and taste, among the food products frozen by CAS technology. Products of “SASHIMI GRADE” that can be stored frozen while maintaining the highest quality possible contribute to ensuring stable ingredients in many hotels and restaurants, expanding the possibilities of the menu items.

At the Senrei headquarters factory, we installed CAS technology equipment in the tunnel freezer for the first time in the world. Mass production of “CAS FRESH” products is made possible as the food material is frozen while traveling on a belt conveyor that is 16m in length, and the environment for stable supply of high quality goods has been established. Furthermore, we utilize various advanced facilities in the factory and promote product development in packages and shapes that are easy for customers to use.

Senrei Scallop Ligaments

In Sanriku, the unique characteristics of the Ria coast are utilized, and in the ocean where a large amount of plankton as food is generated, shells are hung on buoys to slowly grow scallops. Sanriku scallops, grown in a nutrient-rich sea, have a large ligament that is thick and full of flavor. We have a strong confidence in that regard.

We are proud to provide “Senrei Scallop Ligaments” as shelled scallops of the Sanriku area with “CAS FRESH” quality through freeze processing. In surveys that analyzed the taste, it was reported that the taste of CAS frozen processed scallop ligaments is stronger than that of ordinary frozen scallops.

Following thawing, it can be served raw for dishes such as sashimi. In addition, various rich flavors can be utilized to create various menu items.

Moreover, original packages developed independently can be easily used simply by peeling off the stickers and can be used for preservation as they are. Because the container is transparent, the remaining quantity can be confirmed at a glance. It is an easy-to-use 1kg, double pack divided as two is also popular.
