Where does this exist? And how do you get there?

While European women, especially those familiar with combat sports, felt no qualms about giving sumo a go, Japanese women had more to contend with than just the bigger Europeans. Their biggest hurdle came from a stigma that can be traced to the 18th century, when, as entertainment for men, topless women sumo-wrestled blind men. Though this lewd variety eventually faded away in the mid-20th century after being banned repeatedly, a ceremonial form has continued in regional festivals so far out on the fringe of society that it remains virtually unknown.
