Overview
- Tokyo Metro reported smoke from under a Ginza Line train near Asakusa, prompting an emergency stop and a call to the fire department.
- Inspections found damage to a cable in tunnel equipment near Asakusa, and the operator said the visible smoke has subsided.
- Service is halted between Asakusa and Mitsukoshimae, and trains are turning back on the Mitsukoshimae–Shibuya section with no injuries reported.
- The company cited fire-department checks and repair work in progress, with one report pointing to a midday target and another to evening for restoring full operations.
- The Ginza Line is a major commuter route through central Tokyo, so the partial shutdown is likely to cause delays and crowding even with turnback service in place.
