In Fujinomiya City, where the spring water from Mount Fuji is abundant, rainbow trout farming is thriving, and the city boasts the highest production volume in Japan. In 2009, rainbow trout was designated as the “city fish,” becoming an important resource for Fujinomiya City. Among the diverse and high-quality agricultural, forestry, and fishery products of Shizuoka Prefecture, the “Premium Rainbow Trout Akafuji” rainbow trout, which has been certified under the “Shizuoka Food Selection” standards that recognize products with value and features worthy of pride both nationally and internationally, is produced as a large brand-name trout by the Fuji Trout Fisheries Cooperative Association. These fish are grown over two to three years without spawning until they reach a body weight of over 2 kg, resulting in a superior taste that has earned high acclaim.
