Japan interactive railway map. Mainline, regional and freight rail network — filterable by speed, electrification, track gauge and line usage.
Japan rail network drawn from data mapped by OpenStreetMap contributors, covering mainline railways, regional lines, commuter rail and freight corridors. Lines are colour-coded by rail type and filterable by maximum permitted speed, electrification system, track gauge and line usage. The map reveals the layered structure of the network: high-speed intercity spines, slower regional connectors, freight-only branches serving ports and industrial zones, and heritage lines preserved for tourism. Switch between filter modes to view the same railway infrastructure through a different lens — the same line that appears as a passenger main line in usage mode will show its permitted speed and electrification system in the other views.
Japan has 136,660 mapped railway segments including 1,206 tram lines, 3,644 metro segments, 1,124 light rail segments and 1,015 narrow gauge segments. — one of the world's most extensive rail networks.
