We procure eyed trout eggs with excellent growth performance and health characteristics from suppliers in Japan and the United States, ensuring a stable supply sustainably.
* Eyed eggs are eggs in the final stage before hatching, when the eyes of the fish are visible to the naked eye.

Our own hatcheries are located in Fukaura-cho and Imabetsu-cho, Aomori Prefecture. Here, the fish are raised from eggs to juveniles of about 5 g . Only the best quality eggs are hatched, carefully sorted by hand.

We have four intermediate freshwater farms, including two in Fukaura-cho and one in Imabetsu-cho in Aomori Prefecture, as well as one in Akita Prefecture. Juveniles weighing about 5 g are transferred to these farms and raised to about 600 g.
The Omine Intermediate Farm in Fukaura-cho uses water flowing from the Shirakami Mountains, a World Heritage site. The farm in Imabetsu-cho uses a semi-recirculating aquaculture system (RAS). Instead of river water, this farm uses well water.

Seawater acclimation is the process of acclimating intermediate fish raised in freshwater to saltwater. Fish will die if they are suddenly introduced to salty seawater from freshwater, so we acclimate them to seawater gradually over a period of about half a day.

Marine aquaculture is farmed at sea farms located offshore along the coast of Fukaura-cho, from in Imabetsu-cho, Sotogahama-cho, and the Wakinosawa area of Mutsu-city in Aomori Prefecture.These farms receive fish weighing approximately 600 g and grow them to a marketable size of 3 to 4 kg.

At the sea farm in Imabetsu-cho, fish are harvested using fish pump imported from overseas. This method minimizes damage to the fish compared with conventional net harvesting. Harvesting starts before dawn to ensure the produce can be shipped the same day.

Harvested trout are immediately transported to a factory in Aomori City, where primary processing begins early in the morning. This enables the fish to be shipped fresh on the same day.
