Nine-Tailed Fox
Kyubi no Kitsune
白面金毛の九尾狐
The Nine-Tailed Fox is a spirit-fox said to have lived so long and gathered so much power that its tail divided into nine. Yet the name does not simply mean a fox with many tails. In Japanese yokai imagery, the Nine-Tailed Fox is the largest and most complicated fox figure of all: it joins fox worship, Inari belief, fox possession, tales of beauties who unsettle royal power, and the narrative line that runs from Tamamo-no-Mae to the Sesshoseki killing stone. Its source lies in Chinese antiquity. In the Nanshan jing section of the Shan Hai Jing, Mount Qingqiu is home to a beast shaped like a fox, with nine tails, a cry like an infant, and a taste for human flesh. This fox is monstrous; yet in ancient China the nine-tailed fox could also be a propitious beast, an omen of peace. Later Chinese and Japanese texts layered the auspicious fox and the bewitching fox onto one another, turning the nine-tailed fox into both a sacred beast and a nation-ruining spirit. In Japan, fox lore spread in two directions. On one side stood the white fox, messenger of the Inari deity, guardian of fields, business, and household prosperity. According to Fushimi Inari Taisha, Inari descended on Mount Inari in 711, and the faith now extends to roughly thirty thousand shrines across Japan. On the other side stood the wild foxes and possessing spirits that deceive people, cling to households, or take hold of a region: yako, kuda-gitsune, osaki, izuna, and others. The Nine-Tailed Fox stands between these poles. It has the noble aura of a near-divine white fox, but also the danger of entering human society from within and shaking power itself. In Japan, the figure was fixed above all by the stories of Tamamo-no-Mae and the Sesshoseki. Tamamo-no-Mae is told as a peerless beauty loved by the retired Emperor Toba; exposed as a fox, she flees to Nasu, is slain, and becomes a poisonous stone. The three names are related, but they are not interchangeable. The Nine-Tailed Fox is the true form; Tamamo-no-Mae is the courtly incarnation; the Sesshoseki is what remains after death. Once those stages are joined, the fox is no longer just an animal that tricks humans. It becomes a great spirit-fox carrying beauty, intellect, politics, death, and pacification.
