Safenity Japan is a map for comparing public safety across Japanese prefectures and municipalities.
What you can do
• Compare up to three areas by reported crime counts, rates per 100,000 residents, resident population, source year, and source
• Switch between crime and earthquake views
• Search by prefecture, municipality, Japanese name, kana, or Latin name
• Save favorites and reopen up to 12 recently viewed areas
• Share a comparison card as a PNG image and text using the native share sheet
Data notes
Crime data uses the latest available public prefectural or police statistics for each area, including 2025, 2024, or 2023 sources. Rates generally use 2020 resident population. Futaba Town alone uses Fukushima Prefecture’s resident-register population of 5,294 as of January 1, 2025, with its population year and source shown. The adjusted map score is a separate indicator from the resident rate in comparison cards.
Earthquake view shows a separate maximum sampled value from J-SHIS 2024 data: the maximum sampled probability within 30 years of JMA intensity 6 lower or higher. It is not a flood, tsunami, typhoon, all-hazard forecast, or alert service.
Statistics are bundled in the app, so search and comparison work offline. Internet access is required for online map tiles. The optional location button moves the map near your current location. There is no account, advertising, behavioral analytics SDK operated by us, or real-time alert service. When map tiles are displayed, GSI receives your IP address and visible map area, retains logs, and analyzes them internally. See the privacy policy.
Figures are reference information from public statistics and do not guarantee safety. Tokyo town-level data is a reference layer and is not exhaustive.
The UI is available in Japanese, English, Korean, Simplified Chinese, and Traditional Chinese. Place names remain Japanese with Romanized labels where available; they are not fully translated into every UI language.
Sources and status: Crime statistics come from prefectural police and municipal publications; each area detail can open its source URL. Tokyo town-level example: Metropolitan Police CSV (https://www.keishicho.metro.tokyo.lg.jp/about_mpd/jokyo_tokei/jokyo/ninchikensu.files/R6.csv). Earthquake data: J-SHIS API (https://www.j-shis.bosai.go.jp/api-pshm-meshinfo). Map tiles: GSI (https://maps.gsi.go.jp/development/ichiran.html#blank). The earthquake maximum is the maximum among sampled points, not a probability for the whole municipality. Safenity Japan does not represent a government agency or political organization.
