The Tokyo Metropolitan Government has been working with other railway operators to install platform doors at Toei Subway stations. The aim is to have them installed at all 106 stations by the end of this fiscal year.
Up to now, installation has been completed on the Mita Line, Shinjuku Line, and Oedo Line, but on the 20th, installation was completed at Oshiage Station on the Asakusa Line in Sumida Ward. Visually Impaired People's Group: ``It's a very big thing that guarantees safety.''
