USE NOW · FIRST DECISION
Do not rebuild the whole day in the rain
Choose the station you are already near. Keep one indoor anchor, one meal and one optional stop inside the same district. If a weather warning or transport disruption is active, use the official safety information before this itinerary.
- Check the current JMA warning and rain radar.
- Choose Tokyo, Shinjuku or Ueno—do not cross the city merely for a “rainy-day spot”.
- Reserve or verify the indoor anchor before leaving the station.
- Keep the return station and a stop time visible.
DECIDE BEFORE YOU ADD
Three starts, three different rainy days
Set the decision axes before adding more to the day. The cards also work as a quick on-site check.
Architecture, food and a short city story
Use the station’s underground and connected buildings as the spine. Choose the Marunouchi or Yaesu side before following an individual exit; not every final crossing is covered.
One building cluster, not every side of the station
Decide east or west before the gate. Department stores, museums and observation spaces can support a day, but moving between operators and exits can still expose you to rain.
A museum day with one exposed section
Ueno has a strong museum cluster, but the park is outdoors. Pick one museum first, check its admission and walk from the correct station exit without trying to “collect” every museum.
OPEN YOUR SITUATION
Build only the version you need
Only the first situation is open. Use the part that matches you instead of reading a long article from the beginning.
01From Tokyo Station: a low-exposure first dayThis works when you have luggage, jet lag or an afternoon arrival and want to understand central Tokyo without a long transfer.
- Store or deliver luggage before planning anything else.
- Choose Marunouchi for the historic station façade and west-side buildings, or Yaesu for the east-side underground and transport cluster.
- Book one indoor cultural or architectural stop and leave a generous meal window.
- Return through the same named side; do not improvise a different station during heavy rain.
02From Shinjuku Station: stay on one sideShinjuku becomes tiring when a rainy plan repeatedly crosses the railway. East and west are separate day plans.
- Match your arrival operator and floor before choosing an exit.
- Select east for dense shopping and entertainment, or west for the civic and office side; keep the day on that side.
- Check the named facility’s current opening and the covered route it actually provides.
- If the weather worsens, finish at the station rather than adding a distant night view.
03From Ueno Station: let one museum be enoughUeno is best when the rain is ordinary, not when a warning makes park movement unsafe.
- Choose a museum from its own official site, including timed admission and closing day.
- Use the JR station map to leave from the park side.
- Treat the outdoor walk as a real weather section; protect documents and mobility aids.
- Add a second museum only after the first, not before the day begins.
PLAN BEFORE · EASY TO MISS
What a rainy plan often forgets
Admission can become the real bottleneck
An indoor building is not automatically available. Museums can close on a weekday, timed tickets can sell out and observation spaces can restrict entry in poor weather. Open the named facility’s own page before crossing the station. Keep a meal or public building in the same district as a fallback, and never treat a shopping mall as an emergency shelter outside its published hours.
Wet luggage changes every transfer
Umbrellas, coats and suitcase wheels add width and slow a group. Put wet items in a cover before entering a crowd, use staffed luggage services when practical and choose lifts for the complete load—not only for a stroller or wheelchair. A compact day is also considerate: it keeps dripping luggage out of more trains, shops and narrow passages.
UNDERSTAND JAPAN
Why “underground Tokyo” is useful—and misleading
Tokyo’s major stations grew with railways, department stores and office districts, so indoor passages often connect transport with daily life. A rainy day can therefore reveal how the city works: food halls, small shops and public passages are not merely shelter but part of the urban system.
Yet an underground name is not a promise of a continuous roof. Different operators, paid areas, building hours, stairs and a final road crossing can break the route. Use a named station side and building as anchors, then verify the current map instead of following a compass underground.
IF THE PLAN BREAKS
Do not rush to recover; make the route smaller.
- If you are wet and disoriented, enter a staffed public facility or station area before opening another map.
- If your chosen facility is closed or full, replace it with a meal or rest in the same district—not another cross-city journey.
- If warnings, flooding or transport suspensions appear, return to accommodation or follow local instructions.
