Mini JapanRail (jr.suki.ing) is a Japan Train Live Map that visualizes real-time train positions across the whole country. It animates roughly 4,000 trains — Shinkansen, limited express, local lines, subways and trams — on a 3D globe projection covering 600+ railway lines and 8,900+ stations. Features: timetable replay at 0.5–32x speed, route search between any two stations, station lookup, train-type filters, and weekday/Saturday/holiday schedule switching. The UI is trilingual (Japanese, Chinese, English) and the app runs with zero external network requests at runtime. A free web application.
