The Myth
The Sky Fox is an exceptionally powerful celestial fox spirit that emerges after a fox has cultivated its supernatural abilities for a thousand years and developed nine tails. Upon reaching this stage, its fur turns golden, and it ascends to the heavens, becoming a divine beast of extraordinary power. Its celestial transformation grants it the ability to see a thousand li into the distance, allowing it to perceive events far beyond the reach of ordinary creatures. The Sky Fox represents the highest stage of a fox spirit’s cultivation, possessing wisdom, magical abilities, and a place among the celestial beings.
Fox spirits develop their powers through several paths. Some gain wisdom by accidentally swallowing treasures from heaven and earth, while others cultivate their spiritual virtues in places rich in yin energy, drawing upon the essence of the moon. Some learn directly from Taoist monks and masters. Every hundred years, a fox faces a supernatural catastrophe; if it survives, it develops another tail. Many foxes perish or abandon their cultivation before reaching the later stages, making the nine-tailed Sky Fox exceptionally rare. Upon completing a thousand years of cultivation, the fox receives recognition from the Heavenly Court and attains immortal rank.
Despite their divine status, Sky Foxes do not always behave benevolently toward humans. Some descend into the mortal world and cause chaos, requiring Taoist priests to subdue them. Because of their celestial nature, they are generally spared execution and instead punished through beatings or exile. One such Sky Fox, Liu Cheng, was banished to the ancient Korean kingdom of Silla after causing disorder in China. The people of Silla eventually came to revere him as a deity. Another legend describes a Sky Fox possessing a heavenly book containing powerful magical techniques. Humans who attempt to steal this treasure often suffer disastrous consequences, although the Korean hero Jeon Woo-chi succeeds in taking the book and mastering its secrets.
The Sky Fox is also associated with Japanese and Korean traditions. In Japan, the celestial fox is linked to the highest ranks of kitsune, above other supernatural foxes such as kūko, kiko, and yako. Some traditions connect the celestial fox with the tengu, while others describe fox spirits as divine messengers of Inari Ōkami rather than the deity itself. In Korea, the nine-tailed fox known as the kumiho shares several characteristics with the Sky Fox, including golden fur, nine tails, and a heavenly book. These traditions portray the Sky Fox as a rare and formidable being whose supernatural cultivation allows it to cross the boundary between the mortal world and the heavens.
