Plan a public-transit (rail/subway) journey using a self-hosted OpenTripPlanner instance (self-hosted OTP (Kanto rail/subway)). 'from' and 'to' are each a station name (e.g. "新宿") or a "lat,lon" coordinate. Returns ranked itineraries with per-leg lines (line name, stations, minutes), departure/arrival times, and transfer count. Accurate within the covered area (Kanto); returns no route for places outside coverage.

Plan a rail/subway journey and render it as a Yahoo!乗換案内-style vertical timeline (an inline interactive view on claude.ai). The view shows stations, departure/arrival times, line names in their official colors, and transfer points stacked vertically; the same itinerary is also returned as text. 'from' and 'to' are each a station name (e.g. "新宿") or a "lat,lon" coordinate. By default shows the best (fastest) itinerary; use 'routeIndex' to pick another. Prefer this over plan_journey when a visual route is helpful.

Autocomplete station names against the self-hosted OpenTripPlanner instance (self-hosted OTP (Kanto rail/subway)). Returns matching stations with coordinates. Use to resolve or disambiguate a name before plan_journey.
