以下，リポートからの引用： PREVENTING SUICIDES
According to the MLIT report, major rail interruptions of 30 minutes or longer were significantly less common, occurring less than one work day a month across 35 lines. Nevertheless, suicides account for 43.6% of long-term delays, highlighting a disturbing trend still prevalent on the railways.

According to Japan’s National Police Agency, the number of suicides in the country last year was 21,140. This the lowest figure for Japan in more than 20 years, but still one of the highest for a developed nation worldwide. Unfortunately, stories of passengers jumping in front of trains still hit the headlines.

Japanese rail operators began initiatives to curb incidences of train suicides in the late 1990s, which tie in with moves to enhance safety. Platform screen doors – barriers that stretch along the edge of platforms and open and close for passengers – are being installed at more stations in the capital.

“In recent years, we have been committed to installation of platform doors,” says Yamaguchi. “Completion of installation on the entire network is planned for 2025. As of 31 March 2017, installation has been completed on 55% [of the network].”

Visual systems have also been introduced at Tokyo stations to help deter train jumpers. LEDs emitting a calming blue light have been installed at stations along the Yamanote line, which has reportedly reduced suicide incidents since the 2009 peak. Meanwhile, Shin-Koiwa station has installed signs with suicide hotline numbers.
