The high school girl in Japan is as iconic an image of Japanese popular culture as the ninja, Mt Fuji and Hello Kitty.

For whatever pop psychology reason you want to imagine, the teenage girl in a uniform, particularly those that echo the naval uniforms of Europe in the 19th century, is a constant in Japan’s mainstream (and not so mainstream) culture. More interestingly, the fighting high school girl is a uniquely popular phenomenon in Japan – case in point, the iconic characters of Sukeban Deka and Sailor Moon.

In promotion of the 101st High School Sumo Kanazawa Tournament, to be held on Sunday, May 21, 2017, a video called “Sumo Girls Eighty Two Techniques” was released. The Japan pop culture site, SoraNews24, provides details on these 82 techniques.

Most people, however, are likely more interested in the visuals.
