Could you build this?
Partial The planner UI is buildable, but adapting to live rail delays, weather and earthquake alerts plus spoken two-way translation requires real-time transit data feeds and speech pipelines that are harder to assemble and keep reliable.
What it would actually take: Use a mobile app with an itinerary engine, maps and booking integrations, plus feeds from JR operators, JMA earthquake alerts and weather APIs, and speech-to-text and translation services. The hard parts are obtaining timely, licensed Shinkansen status data, handling disruptions with a robust re-planning algorithm, and low-latency bidirectional speech translation in noisy settings.
