Women's sumo

Women's sumo (女相撲) is a form of sumo played by women.

Professional sumo traditionally forbids women from competition and ceremonies. Women are not allowed to enter or touch the sumo wrestling ring (dohyō). Despite this, women sumo wrestlers have existed through history and exist in the present day on an amateur level.

History
The first recorded instance of women performing sumo, according to the Nihon Shoki, is when Emperor Yuryaku (418–479) summoned two courtesans and ordered them to wear loincloths and to sumo wrestle.

Women's sumo would not become common until the 18th century in the middle of Edo (1603–1868), when a form of onna sumo was performed in some areas of Japan. Various types of women's sumo existed, including touring professionals. These continued to exist after the Meiji Restoration, until women's sumo was cracked down upon by the Tokugawa shogunate and Meiji government, as they deemed the organizers of it to be corrupting public morals with these spectacles.

Women's sumo continued to exist despite a government ban in 1926. The practice would only die after the end of World War II, with the last group dissolving in 1963.

Modern times
Female sumo is not considered to be authentic by most Japanese and is now prohibited from taking place in professional settings, but exists on an amateur level.

The International Sumo Federation and its events (such as the Sumo World Championships and European Sumo Championships) allow female competitors. Women's Sumo is an event at the World Games and was also featured at the 2013 World Combat Games.

The first national championship for amateur women's sumo was held in 1997. The rules are identical to men's amateur sumo, with the exception that the wrestlers wear leotards under a mawashi, and the matches last a maximum of three minutes instead of five minutes like the ones in men's amateur sumo.
