Danse de grues du Japon / Dance of Japanese cranes. For the Japanese, the crane—or tsuru—is considered a national treasure, appearing in art, literature, and folklore. The Japanese regard the crane as a symbol of good fortune and longevity because of its fabled life span of a thousand years. It also represents fidelity, as Japanese cranes are known to mate for life.
The Red-crowned Crane (Grus japonensis), also called the Japanese Crane or Manchurian Crane (Chinese: 丹顶鹤 or 丹頂鶴; Hanyu Pinyin: Dāndǐng Hè; Japanese: 丹頂 or タンチョウ, tancho; the Chinese character '丹' means 'red', '頂/顶' means 'crown' and '鶴/鹤' means 'crane'), is a large east Asian crane and among the rarest cranes in the world. In some parts of its range, it is known as a symbol of luck, longevity and fidelity.
