is the term for a championship in Japanese. This article focuses on championships in the sport of professional sumo. It is awarded in each of the six annual honbasho or official tournaments, to the wrestler who wins the most bouts. Yūshō are awarded in all six professional sumo divisions. The prize money for a top makuuchi division championship is currently 10 million yen, while for the lowest jonokuchi division the prize is 100,000 yen. A runner-up is referred to as a jun-yūshō. Perhaps surprisingly, considering that most of the interest in tournaments today revolves around who will win the yūshō, the concept of a prize for a wrestler's individual performance is a relatively recent one. Legendary wrestlers such as Tanikaze and Raiden are credited today with winning many championships, but they are all unofficial and are really nothing more than a "best tournament record." The individual yūshō idea evolved gradually, from wrestlers simply picking up cash thrown into the ring by spectators after winning exciting matches (common in the Edo period), to wrestlers being given trophies and prizes from private sponsors for performances over an entire tournament (beginning in the Meiji period). Trophies were at first given only for undefeated records, but since draws, no decisions and absences were all possible outcomes, several wrestlers could be eligible and it did not necessarily go to the man with the most wins. In January 1900, the system recognised today began to take shape when the Osaka Mainichi Shinbun newspaper announced it would give a prize of a keshō-mawashi decorative apron for either an undefeated record or for the fewest losses, and in the event of a tie, the wrestler who had defeated the most high-ranking opponents would win the prize. Thus the principle of an individual champion was established. Takamiyama Torinosuke's victory in June 1909 was the first to be declared a yūshō, and the system was formally recognised by the Japan Sumo Association in 1926 when the Tokyo and Osaka organisations merged. From June 1909 to October 1931 and from January 1940 to July 1947, there was also a group competition called . The wrestlers were divided into two teams, East and West, and it was the team with the better overall score that was awarded a prize. Though as noted, all six divisions award a championship, the top division championship receives by far the most attention. Consequently, in addition to
