Safety & Emergency
Tokyo consistently ranks among the safer major cities for visitors, but “safe” doesn't mean “nothing to prepare for” — mainly around natural hazards rather than crime.
Earthquakes
Japan is seismically active and buildings are built to a high standard for it. If a quake hits, move away from windows and falling objects rather than immediately running outside.
Emergency numbers
110 police, 119 fire/ambulance, both with English-language support available on request.
Typhoon season
Roughly August through October — trains and flights can be suspended ahead of a storm; build slack into your itinerary during these months.
Lost property
Tokyo has an unusually high rate of lost items being returned — report losses to station staff or a local koban (police box) promptly.
Koban (police boxes)
Small neighbourhood police posts found throughout the city, useful for directions as much as emergencies — staff are used to helping lost visitors.
