paper used in pre-bout rituals
In sumo, a piece of paper used by wrestlers in pre-bout purification rituals, such as wiping the hands or mouth.
The wrestler purifies his mouth with chikara-gami before stepping onto the ring.
Compound of 力 (chikara, 'power') and 紙 (kami, 'paper'). The exact origin of the term is uncertain; it may refer to the paper's role in focusing a wrestler's spirit before a bout.
