On March 1, 2025, the JR East Yamanote Line experienced significant service disruptions due to smoke emanation from the tracks at Yoyogi Station. At approximately 3:10 PM, train operations were halted for both the inner and outer loops as fire services engaged with extinguishing measures and safety checks to assess the situation.
Passengers were abruptly impacted by the shutdown, as many were mid-journey when the delay was announced. Initial estimates suggested the resumption of services around 4:10 PM, but safety assessments required additional time, leading to updated estimates of around 4:40 PM for the resumption of regular operations.
Reports from JR East indicated the swift action taken by firefighting teams to manage the situation efficiently. They deployed effectively to address the source of the smoke, emphasizing the importance of passenger safety.

By approximately 4:30 PM, operations on both tracks were confirmed to have resumed, with trains gradually returning to their regular schedules.

The incident briefly highlighted underlying issues with service reliability, as several passengers expressed concerns about how such occurrences could impact their daily travels. Observers noted, "The Yamanote Line is known for its punctuality and frequency.
