Distribution

Asia: central Hokkaido, Japan. A hybrid specimen with the introduced masu salmon Onchorhynchus masou masou was collected in the inlet stream, Yamada Creek, of the Lake; mtDNA suggests that the mating occurred between a femalel Miyabe charr and a male masu salmon; hybridization may cause deleterious effects on Miyabe charr (Ref. 56618).
