The September Sumo Tournament, officially known as the Aki Basho or Autumn Grand Sumo Tournament, is one of Japan’s six major professional sumo events held each year. It takes place over 15 days in September at Ryogoku Kokugikan, Tokyo’s renowned indoor sumo stadium. Unlike team sports, sumo features individual wrestlers representing professional training stables, called heya, and competing for wins and ranking advancement. The tournament brings together athletes from the top makuuchi division and the sport’s lower divisions, with each wrestler aiming to finish with more victories than defeats. Fans can watch celebrated champions, including yokozuna and ozeki, face rising contenders in bouts decided when a wrestler is forced out of the ring or touches the ground with a body part other than the soles of the feet. The Aki Basho is a key event in the professional sumo calendar, attracting spectators to Ryogoku Kokugikan and viewers around the world. Tournament dates and participating wrestlers vary from year to year, while the 15-day format and traditional rules remain central to this major Japanese sporting event.
