While professional sumo wrestling in Japan maintains its 1,500-year-old tradition of excluding women from the sacred ring, a growing movement of more than 600 female amateur wrestlers is challenging gender barriers and pushing for the sport’s inclusion in the Olympics.

Some key facts:



• Women remain barred from the traditional sumo ring (dohyō) in professional sumo, despite the sport’s 1,500-year history in Japan.

• More than 600 female amateur wrestlers (rikishi) are currently practicing sumo in Japan, representing a small but growing movement.

• Airi Hisano, considered Japan’s strongest female rikishi, weighs 115 kilograms and stands 1.72 meters tall (about 250 pounds, 5-feet-7) while working a day job at Tachihi Holdings.

• Rio Hasegawa became the first female to join the Keio University Sumo Club since its founding in 1919 and is the 2024 middleweight world champion.

• Female wrestlers compete wearing spandex shirts and bodysuits under their mawashi, unlike male wrestlers who compete bare-chested.
