Tokyo rainy-day decisions with kids: choose the next hour
When rain changes a Tokyo family day, decide only the next useful hour: confirm the weather and transport situation, choose one indoor anchor with its own live visitor guidance, and leave the later plan optional.
Quick answer
Do not rebuild the entire day at breakfast. Check official weather and transport information, pick one indoor venue that currently accepts visitors, and delay the second decision until the family reaches that anchor.
Use official live information for decisions that can change. The Japan Meteorological Agency publishes warning information, and Tokyo Metro provides route and station information. A venue’s own page is the final source for its opening, tickets and event conditions.
Choose the indoor anchor by the journey you can still make, not by a long list of rainy-day ideas. If one option requires a fixed ticket, confirm it before travelling.
Make the next hour easy: travel, arrive, use the venue’s current entry guidance, then reassess. A food break or earlier return can be a valid alternative if the journey has already used the family’s energy.
For severe weather or a transport disruption, follow the operator and public-agency information rather than trying to preserve an itinerary.
