A video—purportedly showing an incident involving a Japanese woman on a Tokyo subway platform—has been circulating on overseas websites, drawing significant attention due to its shocking nature. Although labeled as “recent,” I vaguely recall seeing it before, so the information is likely inaccurate. The post featured three videos.

A gap of 100% for the Toei Subway versus 34.8% for JR
The video currently circulating—purportedly showing a person being struck by a train at a Tokyo subway station—cannot be verified in terms of when it was filmed or whether it is authentic. However, the installation of platform screen doors—a key measure for preventing such accidents—varies significantly across different railway lines in the Tokyo metropolitan area.
The Toei Subway network has achieved a 100% installation rate across all its stations, and the number of incidents involving falls from platforms has dropped sharply, from 86 in fiscal year 2009 to just 2 in fiscal year 2022. In contrast, the installation rate at JR East stations within Tokyo stood at 34.8% as of the end of fiscal year 2023, while the figure for all JR and private railway lines combined remains at only 38.9%. In fact, the JR Chuo Rapid Line saw 17 such incidents in 2024, and the Sobu Local Line saw 12—numbers that have remained persistently high in recent years. With a target date of 2031 set for the completion of platform screen door installations across 36 railway lines in the Tokyo area, it is possible that the disparity in progress between the well-equipped subway lines and the lagging JR lines is contributing to a difference in the likelihood of accidents occurring.
