thumb|Sessho-seki in 2016 The , or "Killing Stone", is a stone in the volcanic mountains of Nasu, an area of Tochigi Prefecture, Japan, that is famous for sulphurous hot springs. In Japanese mythology, the stone is said to kill anyone who comes into contact with it. In Japan, rocks and large stones in areas where volcanic toxic gases are generated are often named Sessho-seki (殺生石), meaning Killing Stone, and the representative of such stones is this one associated with the legend of Tamamo-no-Mae and the nine-tailed fox.

==Legend== The stone is believed to be the transformed corpse of Tamamo-no-Mae, a beautiful woman who was exposed as a nine-tailed fox working for an evil daimyō plotting to kill Emperor Konoe and take his throne. According to the otogi-zōshi, when the nine-tailed fox was killed by the famous warrior named Miura-no-suke, her body became the Sessho-seki. Later, a Buddhist priest called Genno stopped for a rest near the stone and was threatened by the spirit of Tamamo-no-Mae. Genno performed exorcism rituals and begged the spirit to consider her salvation. Tamamo-no-Mae relented and swore never to haunt the stone again.
