Salvelinus leucomaenis, the whitespotted char, is an East Asian trout in the genus Salvelinus, called iwana in Japanese. Both landlocked and ocean run forms occur. The landlocked form grows up to 14 inches, and prefers low-temperature streams. The seagoing fish can grow over two feet long. The oldest reported specimen was nine years old.
Iwana is widely fished in Japan. Apart from Hokkaido in Japan, the species is found in northeast Korea and in Russia in Sakhalin, Kuril Islands and Kamchatka.
The kirikuchi char (Salvelinus leucomaenis japonicus or Salvelinus japonicus) is usually considered a subspecies of S. leucomaenis. Two other subspecies are also listed, S. l. imbrius and S. l. pluvius.
