Railway electrification in Japan

This is a list of railway electrification systems in Japan.

As of 2005[update], the rail system consists of the following:[1] 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.

Part of Tateyama Kurobe Alpine Route suspended service since 2019 consist of JR Kobe Line, Wadamisaki Line and Sanyo Line Hiroshima the rest 1,435 mm gauge section (Hakone-Yumoto – Gōra) uses 750 V, dead section within Hakone-Yumoto the rest 1,435 mm gauge section (Hakone-Yumoto – Gōra) uses 750 V, dead section within Hakone-Yumoto Concurrent with Yamagata Shinkansen (Fukushima – Shinjō) and Akita Shinkansen (Ōmagari – Akita) formerly part of Esashi Line until 2016 part of Fukuhoku Yutaka Line on the electrified section Concurrent with Hokkaido Shinkansen between Shin-nakaoguni signal base – Yunosato-Shiriuchi signal base formerly part of Esashi Line until 2016
