# Railway electrification in Japan

This is a list of railway electrification systems in Japan.
All lines use an overhead line power supply unless otherwise noted. As of 2005, the rail system consists of the following:
* 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.
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.
