Live feed of every active rail disruption across the Japanese (JP) network in one call — delays and suspensions with bilingual summaries, refreshed continuously from ODPT. Built for MONITORING agents: poll on an interval (e.g. every 5 minutes) to maintain a nationwide incident watchlist without querying stations one by one.

Current service disruptions on a specific Japanese (JP) train line: status, estimated delay, cause, and last-updated time, with a bilingual summary. Sourced live from ODPT. Use to monitor one line for delays or suspensions.

Directory of Japanese (JP) rail operators and their lines, with canonical ids and Japanese/English names. Use to discover valid line and operator identifiers for the other endpoints.

Plan a route between two Japanese (JP) train stations — timetable-based, with transfers, duration, and fare. Standard planning without delay adjustment (cheaper). Use for ordinary trip planning.

Real-time delay and operational status for a Japanese (JP) train station — per-line status (normal / delayed / suspended), estimated delay minutes, and cause — plus a one-line summary in English and Japanese. Sourced live from ODPT. Use to answer 'is my train delayed' for a station.

Fuzzy-search Japanese (JP) train stations by name — accepts kanji, kana, or romaji and tolerates the 駅/station suffix. Returns matching stations with their operators and lines. Use to resolve a station name to a canonical record.
