Black kokanee (Oncorhynchus kawamurae), or kunimasu (国鳟; "[Japanese] national trout") in Japanese, is a species of landlocked Pacific trout in Japan that was thought to be extinct for 70 years before being rediscovered in 2010. The species was originally endemic to Lake Tazawa, Akita Prefecture, but was translocated to Lake Saiko in an attempt to save the species. These efforts were only discovered to have been successful in 2010 when nine specimens were captured by a team of researchers including a celebrity biologist, 'Sakana-kun'.
