— sumo wrestling:
Sumo is the ritualized ancient sport of Japanese wrestling in which two opponents face off across an elevated ring and try to down or oust the other. The first wrestler to either touch the ground with anything other than the bottoms of his feet or leave the ring loses. There are six main sumo tournaments a year, each lasting fifteen days, with the best wrestlers being declared a yokozuna, a grand champion. There are no weight restrictions in sumo wrestling–any wrestler may face any other–the highly trained sumo athletes put on as much weight as possible, hoping to gain a force advantage in the ring.
