Hundred Years of Know-how and Passion for Eel

The port town of Isshiki in Nishio, Aichi, draws on a centuries-old tradition and hard work to produce its delicious eels. Famous throughout Japan, Isshiki Unagi is produced according to the strictest food safety standards.
Nishio Unagi

  • Consistent Production from Fry to Adult Fish

    To ensure food safety, Isshiki eels are closely monitored as they mature from small fry, called shirasu, to adult fish.

  • Thorough Quality and Safety Inspections

    For safe production, chemicals are used in aquaculture. All fish are thoroughly tested for drug residue. We ship only certified clean and safe eels.

  • Clear Water from the Yahagi River

    All the farming ponds in Isshiki use only fresh, clear water from the Yahagi River. Because our eels grow up in a natural environment, they enjoy healthy growth.

  • Soft Skin and rich Flavor guaranteed

    In addition to the natural ingredients, Isshiki eels are bred under optimum water temperature and with quality feed. Cultivation of eels requires conditions as close to nature as possible. With ponds neither too big nor too small, our Isshiki eels are famous nationwide for their soft skin and rich, fatty flavor.

Unagi's history

Eels have been raised in the warm waters of Mikawa Bay since the Meiji Era. Isshiki began exploring aquaculture in 1904 and rapidly expanded it in the wake of the Isewan Typhoon in 1959, when many flooded farms were converted into eel ponds. Glass-house based warm-water aquaculture has also been spreading since the 1940s.

Shipment of Unagi

Isshiki eel shipped to the whole country

Summer is the peak season for eel shipments. Shipments of eels called “sukui” will begin in the water until about a month before the day of summer use. The live eel is packed in a basket called “Douman” and collected. They are then stored in groundwater for a few days to spit mud and tighten the fish and transported to wholesale stores and restaurants throughout the country.

Shirasu eel fry depend on natural resources. If they thrive, the season’s eel production goes up as well. Of the 4.081 tons of eel produced in Aichi prefecture, 3.350 tons, about 80%, were produced in Nishio. Indeed, one in five eels eaten in all of Japan are from Isshiki.

  • From Birth to Shipping
  • Shirasu fishing
    After breeding in the sea, eels start swimming upstream at the end of the year and continue to do so until spring. Shirasu small fry are then caught and bred in aquaculture.
  • Aquaculture
    They are fed twice a day, once in the morning, once in the evening, until the fish reaches a weight of about 100 grams.

  • Pond raising
    Adult fish of about 200 to 300 gram are then harvested by the pond owner and sold on to a wholesaler.
  • Separation
    Eels are sold in five kilo batches of the same size and quality. They are then kept in sweet water for a few days, to improve the taste.
  • shipment
    For shipping, eels are placed in ten kilo ice or oxygen bags and packaged in 20 kilo cardboard boxes.
    Labelled shusui, Isshiki eels are shipped all around Japan.
