# Sumo World Championships

The Sumo World Championships is an amateur sumo competition organized by the International Sumo Federation. The men's competition started in 1992 and the women's competition started in 2001, with both competitions having been held together. The competitions are generally held every year, although the 2009 and 2011 events were cancelled due to the 2009 flu pandemic and political unrest over the Arab Spring respectively. The 24th edition, originally scheduled to take place in Russia in 2022, was rescheduled to be held in Tokyo in late 2023.
