The Tokyo metropolitan government will install security cameras on all cars of its Toei Subway and Nippori-Toneri Liner trains by the end of fiscal 2024 to prevent groping, terrorism and other threats.

The government’s Bureau of Transportation, which operates the lines, said it has procured enough cameras for the project.

“We will commit ourselves to a swift implementation framework with an eye toward completing camera installation by the end of fiscal 2024,” the bureau’s chief, Hideo Kuga, said at a Tokyo metropolitan assembly session on Dec. 12.

Three to four crime-prevention cameras will be installed on each of the 1,208 cars of the 150 Toei Subway trains, and two each on the 100 cars of the 20 Nippori-Toneri Liner trains.

Some security cameras were recently put into service as part of the metropolitan government’s train update.

As of the end of fiscal 2022, cameras were operating on 76 trains of the Asakusa Line and other Toei Subway sections, along with eight on the Nippori-Toneri Liner.

After 17 passengers were injured in a stabbing attack on a Keio Line train in October 2021, Tokyo decided to install cameras on all trains, including older ones.

By April last year, the metropolitan government secured the additional 1,938 cameras at a cost of 356 million yen ($2.4 million).
