Kaname-ishi
Mythological rock in Japan / From Wikipedia, the free encyclopedia
Kaname-ishi (要石, kaname-ishi, perhaps "foundation stone" but maybe more aptly "cap stone")[1][2] is a mythological rock that was believed to hold down the Japanese archipelago. It was believed that when it was jostled or disturbed, it caused earthquakes. It is located in Kashima, Ibaraki.[1]
Many earthquakes were believed to have been caused by the catfish Namazu which dwelt near it. The catfish was later restrained by Takemikazuchi, protecting against earthquakes.[1][2] When the Takemikazuchi lets his guard fall, Namazu thrashes about and agitates the stone, causing violent earthquakes[3]
In the namazu-e or catfish prints of the Edo period, Takemikazuchi/Kashima is depicted attempting to subdue the catfish, protect the stone, and prevent earthquakes.[4][5] The paintings are believed to give protection against earthquakes themselves, and had a massive increase in popularity.[6]
