Sankei Shimbun
Due to issues of criminal insanity, the mass media had not initially revealed Nishizawa's name when reporting on the case. However, on July 27, the Sankei Shimbun published his name and photograph, with the claim that the incident was a "serious crime". Following this case, the practice of publishing suspects' names in similar circumstances increased in Japanese tabloids and news weeklies, and eventually, national newspapers and news agencies.
