The Black Tortoise (Chinese: 玄武; pinyin: Xuánwǔ) is one of the Four Symbols of the Chinese constellations. Despite its English name, it is usually depicted as a tortoise entwined together with a snake. The name 玄武 used in East Asian languages does not mention either animal; the alternative name "Black Warrior ~ Dark Warrior ~ Mysterious Warrior" is a more faithful translation.
It represents the north and the winter season, thus it is sometimes called Xuanwu (Black Tortoise, lit. Black Warrior) of the North (Chinese: 北方玄武; pinyin: Běifāng Xuánwǔ).
In Japan, it is named Genbu. It is said to protect Kyoto on the north side, being one of the four guardian spirits that protect the city. It is represented by the Kenkun Shrine, which is located on top of Mt Funaoka in Kyoto.
The creature's name is identical to that of the important Taoist god Xuanwu, who is sometimes (as in Journey to the West) portrayed in the company of a turtle and a snake.
