Oncorhynchus kawamurae (Osteichthyes: Salmonidae) (common name "Kunimasu"), a species endemic to Lake Tazawa, Akita Prefecture, Japan, was believed to have been extinct since 1940. However, nine specimens were discovered in March and April 2010 in Lake Saiko, Yamanashi Prefecture, one of the lakes to which eyed eggs of the species were introduced in 1935. These were identified as O. kawamurae because of having 47-62 pyloric caeca, 37-43 gill-rakers, a black-colored body, and spawning at 30-40 m depth in early spring, which are unique characteristics within Oncorhynchus. Furthermore, the distinctiveness of Kunimasu from sympatric kokanee (O. nerka) was supported by microsatellite DNA data.
