Byakko (白虎 or びゃっこ, Byakko) is a creature from Japanese folklore.
Byakko is a celestial white tiger. His home is in the western sky. He spans seven of the twenty-eight Chinese constellations, taking up one quarter of the entire sky. The constellation which makes up the rear of the tiger is located in Andromeda and Pisces. The constellations which makes up the middle of the tiger are located in Ares and Taurus. The constellations which makes up his front legs and head are located in Orion.
Byakko is one of the shijin, or Four Symbols, which are important mythological figures in Taoism. Byakko is the guardian of the west. He is associated with the Chinese element of metal, the season of autumn, the planet Venus, and the color white. He represents the virtue of righteousness. He controls the wind.
Byakko and the other shijin were brought to Japan from China in the 7th century CE. They are strongly associated with Taoism, feng shui, astrology, the five element theory, and other forms of Chinese mysticism. Japan’s ancient capitals were built in correspondence to these beliefs, with each of the quadrants of the city dedicated to one of the Four Symbols. Excavations of ancient burial mounds in Nara has revealed paintings of Byakko and the other shijin on the tomb walls.
In later centuries, belief in astrology waned, and worship of the Four Symbols was gradually supplanted by worship of the Four Heavenly Kings of Buddhism. Their use as symbols, however, continued.
