Network data representing the nationwide railway network
- This data represents the network structure of railway lines using "railway links" which represent information about railway lines and "railway nodes" which represent information about railway stations. It also includes color codes for each railway line and station numbers that conform to station numbering.
- It covers all railway lines, including JR, private railways, monorails, cable cars, and trams, and stores them as network data.
- We also provide point data for station names and line names, enabling a wide variety of map representations.
