在2008年6月8日當地時間的下午12時30分，在日本秋葉原發生一起震驚人心的無差別隨機殺人事件。行兇者加藤智大是日研總業的派遣員工，由於要被公司裁員，再加上長期缺乏朋友和女友的關愛，心情極度低落無處宣洩，又與網路上與酸民多次互相謾罵。

在6月5日找不到公司制服後，他認為已被解雇，終於徹底引爆其反社會人格，於是在隔天購買凶器。在6月7日，開始勘查地形和路況，在當天的網路上留言預告整個殺人計畫。在極短的時間內砍傷12人，最終導致7人死亡。

在被判死刑後，加藤不服上訴，並於2014年1月出版自傳《東拘永夜抄》。由於這起殺人事件，他的弟弟受到網友長期的霸凌，最終在不堪其擾下於2014年2月自殺身亡。而眾多日本網友並沒有任何同理心，反而開心慶祝。

2022年7月26日，加藤智大正式被執行死刑，之後也出現多起類似的模仿事件。在2024年1月3日，一名20多歲的女性從JR的上野抵達秋葉原站後，開始在電車上隨機砍人，造成4名男子輕傷。令人震驚的是，犯案的原因居然只是想單純的殺人。回顧2014年，臺灣的地鐵站也曾發生過23歲男子鄭捷的隨機殺人事件，造成4名乘客死亡和24人受傷的悲劇。

On June 8, 2008, at 12:30 PM local time in Akihabara, Japan, a shocking indiscriminate random murder incident occurred. The perpetrator, Tomohiro Kato, was a dispatched employee of Nihon Kogakuin, and due to impending company layoffs, combined with a prolonged lack of friends and romantic relationships, he was severely depressed and had nowhere to vent his emotions. Additionally, he had engaged in multiple online arguments with netizens.

Unable to find his company uniform on June 5, he believed he had been terminated and, as a result, completely unleashed his antisocial personality. He then purchased weapons the next day. On June 7, he began surveying the terrain and road conditions, leaving messages online that hinted at his entire murder plan. In an extremely short period, he attacked and injured 12 people, ultimately causing the death of 7 individuals.

After being sentenced to death, Kato did not appeal and published his autobiography, "Toho Eiyasho," in January 2014. Due to this murder incident, his younger brother suffered prolonged cyberbullying from netizens and tragically took his own life in February 2014, unable to withstand the harassment. Many Japanese netizens showed no empathy and, instead, celebrated the news.

On July 26, 2022, Tomohiro Kato was officially executed, leading to several similar imitation incidents. On January 3, 2024, a woman in her twenties arrived at Akihabara Station from JR Ueno and randomly attacked people on the train, causing minor injuries to four men. Shockingly, the motive behind the crime was simply a desire to kill. Looking back at 2014, Taiwan's subway station also experienced a random murder incident by a 23-year-old man named Cheng Chieh, resulting in the tragic death of four passengers and injuries to 24 others.
