Kokkuri (こっくり, 狐狗狸) or Kokkuri-san (こっくりさん) is a Japanese game popular during the Meiji period that is also a form of divination, based partially on Western table-turning. The name kokkuri is an onomatopoeia meaning "to nod up and down", and refers to the movement of the actual kokkuri mechanism. The kanji used to write the word is an ateji, although its characters reflect the popular belief that the movement of the mechanism is caused by supernatural agents (ko 狐, foxes; ku 狗, tengu; ri 狸, tanuki).
The word kokkuri refers to the game, the actual physical apparatus, and the spirit(s) believed to possess the apparatus in order to communicate with humans. The physical mechanism is composed of three bamboo rods arranged to make a tripod, upon which is placed a small pot, which is covered by a cloth. Three or more people will place their hands upon the kokkuri and ask the spirits a question, which that spirit will in theory answer by moving the pot or remaining still.
Japanese folklorist Inoue Enryō wrote about the kokkuri phenomenon, denouncing it as mere superstition, yet his efforts did not succeed in depopularizing the game. Some scientific figures of the age attempted to explain the phenomena with the more scientific sounding yet ultimately equally mysterious term "human electricity".
