Railway electrification in Japan

This is a list of Railway Electrification Systems in Japan: Overhead line power supply, unless otherwise noted. The rail system consists of the following (As of 2005):[1]

20,264 km (12,591 mi) of 1,067 mm (3 ft 6 in), of which 13,280 kilometres (8,250 mi) is electrified;
3,204 km (1,991 mi) of 1,435 mm (4 ft 8 ¹⁄₂ in) standard gauge, all electrified;
117 km (73 mi) of 1,372 mm (4 ft 6 in) Scotch gauge, all electrified;
11 km (6.8 mi) of 762 mm (2 ft 6 in) narrow gauge, all electrified.

Japan's conventional mainline railway network schematic map showing electrification systems with voltages and frequencies as of 2017. Third-sector railways are included. Shinkansen exclusive-use trackage is not included. Municipal subways and other rapid transit networks are not included. Private railways are not included.

Electrification systems used by the Japan Railways Group, Japan's formerly state-owned operators, are 1,500 V DC and 20 kV AC for conventional lines and mini Shinkansen and 25 kV AC for Shinkansen. Electrification at 600 V DC and 750 V DC are also seen in private lines and non-rail based transit systems. The frequency of the AC power supply is 50 Hz in Eastern Japan and 60 Hz in Western Japan.
