Background and Context
On the evening of 3 November 2016 in Nakano, Tokyo, Jiang Ge, a 24-year-old Chinese graduate student, was stabbed to death outside her apartment building. The case became widely known as the “Mr. Big’ murder because the accused, Chen Shifeng, had borrowed money from a lending company associated with that nickname. This verified explainer outlines established facts, court rulings, and the lasting social impact, drawing on court documents, media reports from major outlets, and expert analysis.
Key Events on the Night of 3 November 2016
Jiang Ge had gone to a nearby convenience store to wait for her friend, Liu Xin, who had been involved in an earlier conflict with Chen Shifeng. When Jiang returned to the apartment building with Liu, Chen confronted them and attacked Jiang with a knife. Liu survived the assault and cooperated with police. Emergency responders arrived, but Jiang was pronounced dead at the scene. The motive was linked to the prior dispute and the defendant’s attempt to avoid accountability for the earlier conflict.
Legal Proceedings in Japan
Chen Shifeng, a Chinese national residing in Japan, was arrested and charged with murder and obstruction of justice. The Tokyo District Court held a public trial, during which evidence including messages, prior threats, and the sequence of events was presented. In 2017, the court sentenced Chen to 20 years in prison. Both the prosecution and the defense filed appeals. In 2018, the Tokyo High Court dismissed the appeals and upheld the 20-year sentence, a decision widely reported as final within the Japanese judicial process.
