Check the forecast before leaving, react by condition instead of guessing, and do not commit to a route until weather and operator status both look stable.
Fast decision card
Use this before reading the full guide.
Do first
Check JMA forecast and warning pages before leaving on rain, snow, wind, or heat-risk days.
Screenshot your hotel name, address, and one safe fallback route before you move. If trains stop, pause before entering the station and confirm whether bus, taxi, or waiting is the smarter move.
Avoid
Walking into a station during a suspension before checking operator status.
Treating typhoon, heatstroke risk, or heavy snow like a normal sightseeing day. Assuming a pass matters if the entire line is suspended.
