The kirikuchi char, Salvelinus leucomaenis japonicus, is a freshwater fish in the Salmonidae family. It is endemic to the Kii Peninsula of central Honshu in Japan. It is the southernmost population of the char genus Salvelinus and is considered a relict in its region. Other fish of the same genus have, however, been introduced in the area, and the kirikuchi char is hybridizing with them extensively.[2] Kirikuchi char remain in two separate headwater streams of the Totsu River system, and they retain little genetic variation.[2]
