Why is "Hundred man killing contest" trending?

Wikipedia Overview

The hundred-man killing contest was a sensationalized story published first in prominent Japanese newspapers including the Tokyo Nichi Nichi Shimbun and Osaka Mainichi Shimbun in late 1937 during the Japanese invasion of China. The articles described two Japanese Army officers, Toshiaki Mukai and Tsuyoshi Noda, competing to see who could kill 100 people with a sword first while advancing toward Nanjing. Reporters covered the "contest" as if it was a sporting event, complete with running tallies and competitive banter. Later, other Japanese newspapers had picked up and reprinted the stories. However modern historians widely regard these newspaper accounts as Japanese wartime propaganda or exaggeration. The original accounts printed in the newspaper described the killings as hand-to-hand combat; however, historians have suggested that they were most likely a part of Japanese mass killings of Chinese prisoners of war.
