What this map shows

Zoom in to see each fatal accident as a point. Tap a point to see the year, the time of day and the type of accident.

Tap “Show accidents near me” to move the map to where you are. Choose a prefecture to count only the accidents there.

Use the year and time-of-day sliders to narrow the period. Choose “Night only” or “Pedestrians” to see where accidents on dark roads or while crossing are most common.

Turn on “Also show injury-accident hotspots” to see the junctions and roads where accidents, including those with injuries, happen most. Use it to check school routes and the roads you use every day.

Questions and answers

What counts as a fatal accident?

An accident in which someone died within 24 hours (the National Police Agency's definition). Statistics that count deaths within 30 days give different numbers.

Why is there no date or exact time?

So that the people who died cannot be identified, the map shows only the year and a four-hour time band, and locations are blurred to about 100 m.

When is it updated?

Once a year, after the National Police Agency publishes the previous year's accident data.

Pages by prefecture

Back to the map of all Japan

A "fatal accident" is one in which someone died within 24 hours (the National Police Agency's definition). Counts differ from statistics that count deaths within 30 days.

Locations are the accident sites recorded by the police. So that no one who died can be identified, each location is blurred to about 100 m (still fine enough to see which intersections are dangerous). For the same reason the map shows only the year and a 4-hour time band (e.g. 20:00-24:00), never the month, day, exact time, age or sex (age is used only for the national totals).

"Injury-accident hotspots" count every accident with casualties, including injuries only, in squares of about 50 m. When an intersection sits on the edge of a square, its count can be split between two squares.
