- Residents comparing traffic accidents by municipality
- Worth noticing
- Per-capita rates use January 1, 2026 population; the dataset covers injury and fatal crashes, not property-damage incidents.
Field notes
The prefecture table can be sorted by accident count, year-over-year change, fatalities, population-adjusted rates, pedestrian involvement, and nighttime share. Selecting a prefecture leads to municipality listings and a map; a municipality-name search is also shown. The methodology notes that population rates use January 1, 2026 resident-register figures, with ward-level population used for designated cities. The site cautions readers not to treat raw counts alone as a measure of road danger.
