Kyushu Railway Co. said Wednesday it will install security cameras on its shinkansen bullet trains running in the southwestern main island of Kyushu from November to enhance security ahead of the 2020 Tokyo Olympics and Paralympics.

The railway operator will introduce the cameras in passenger cabins and the decks of the 800 Series Shinkansen connecting Hakata in Fukuoka Prefecture, the biggest railway station in Kyushu, and Kagoshima-Chuo Station on the southern tip of the island.

By 2020, the operator aims to complete installation of the cameras on all of its 19 shinkansen bullet trains, including adding more on the N700 Series that connects to the Sanyo Shinkansen Line running in western Japan, it said.

Currently, on the N700 Series, cameras are only installed on the decks. They will be installed on the passenger cabins from fiscal 2018, the company said.

The railway operator hopes the introduction of the cameras, with continuous recording, will help prevent crimes such as molestation, officials said.

To be considerate of passengers' privacy, it will allow a limited number of employees to access the video data.
