>>9794Only partially true. Sumo in Japan has a religious/ceremonial aspect which excludes women once they reach a certain age. There are, however, female Sumo wrestlers in Japan. They compete at international competitions like the olympics, but are usually forced to retire once they reach that certain age.
There's a Netflix documentary about it here in the UK called 'Little Miss Sumo' or something like that. I actually met the guy who made it.
