An Aug. 16 episode of Tokyo MX's variety show "Hirukyun!" found comedian Ken Horiuchi (better known as Horiken) joining the hosts in the studio. Over the course of his stay, he launched the other TV talent and stage hands into a wall of cardboard boxes, before throwing some at people too (including staff who presumably had nothing to do with the bit). Later, Horiuchi picked up Minami Tanaka and Ahn Mika to perform "cleaning," which involved swinging them by the legs so that their hair worked like a broom or a mop.

This slipped by for a bit, until a user on Twitter expressed their disgust at the segment and shared the offending clips. The topic lit up online, with many condemning the footage as examples of sexual harassment and violence against women. Some registered complaints with Tokyo MX, while one of the prevailing sentiments that emerged on social media was, "Why is this being aired in 2018?"
