Sumo (相撲) wrestling is the national sport of Japan, but it had religious beginnings as a ritual act in dedication to the gods to pray for a good harvest. Sumo today had influences from the various wrestling styles in the region, namely Mongolian Bökh, Chinese Shuai jiao, but Japanese Sumo remains unique with its colorful ritual and uncommon terms. The Grand Tournament takes place yearly at Tokyo (Jan, May, Sep), Osaka (Mar), Nagoya(Jul), and Fukuoka (Nov)., and each tournament last 15 days. Ryōgoku Kokugikan is the location in Tokyo, where one can queue for a economical day ticket, limited to 350 individuals per day only. The daily tournament starts with bouts from the most junior division Jonokuchi, proceeding to Jonidan, Sandanme, Makushita. Jūryō and Makuuchi are the top 2 tiers, they happen in the late afternoon and their bouts were preceded with Ring Entering Ceremony, call Dohyō-iri. Dohyō refers to the wrestling ring and these wrestlers (formally known as sekitori in contrast to rikishi from the lower divisions) wear a special apron call keshō-mawashi, whereby mawashi is the belt that wrestlers wear during practice and competition. Chrichozu refers to the pre-bout ritual, whereby wrestler meet, greet, asked for blessing by clapping, purify the ring with salt, stomp out demons with their feet, professed that they had no weapons, both fist on the ground and finally, start of a bout that is usually very short. A battle is lost when a wrestler touches the surface of the ring with any other part of his body besides his feet, or when a wrestler get thrown, pushed or lifted by his opponent to the outside the ring.
