Also known as the Red-crowned crane or Manchurian Crane, the crane represented luck, longevity and fidelity in East Asia. In Japan, this crane, known as tancho(丹頂, origins in China), is said to live 1000 years. A pair of Red-crowned Cranes were used in the design for the Series D 1000 yen note. In the Ainu language, the Red-crowned Crane is known as sarurun kamui or marsh kamui.
