JR East suspended all services on the Tokaido and Keihin-Tohoku lines today following a person-injury accident between Shinagawa and Kawasaki stations [1, 2].
These lines serve as critical arteries for commuters in the Greater Tokyo Area. A total suspension of service on both the Tokaido Line and the Keihin-Tohoku Line creates significant transit bottlenecks for thousands of passengers traveling between Tokyo and Kanagawa prefectures.
The accident occurred between Shinagawa Station and Kawasaki Station [1, 2]. Due to the incident, JR East halted operations across the entire Tokaido Line from Tokyo to Atami, and the Keihin-Tohoku Line from Omiya to Ofuna [1, 2].
Reports regarding the timing of the incident differ between sources. One report said the accident occurred around 4:31 p.m. [2], while another indicated it happened around 6:30 p.m. [1].
Similarly, the projected time for the resumption of services varied. One source said that trains would begin running again around 5:50 p.m. [2]. However, a later report suggested that service would not resume until around 8:00 p.m. [1].
JR East said that the suspension was a direct result of the person-injury accident [1, 2]. The company has not released further details regarding the condition of the individual involved.

The disruption of these two specific lines simultaneously indicates a major failure in the transit corridor between Tokyo and Kawasaki. Because the Tokaido and Keihin-Tohoku lines often serve as redundancies for one another, a simultaneous shutdown forces passengers onto alternative private railways or buses, typically resulting in severe overcrowding across the regional network.
