Radiation Monitoring in the Fukushima Restricted Zone
The difficult-to-return zone is the part of Fukushima Prefecture where evacuation orders remain in effect after the accident at the Fukushima Daiichi Nuclear Power Station.
The map combines current radiation-monitoring stations with a vector outline based on the official Fukushima Prefecture evacuation-zone map dated 31 March 2025 and checked against the METI status map dated 1 April 2026. The outline is provided for public information and is not a legal or cadastral boundary.
Why Is Verification Necessary?
Map readings are indicative data from their respective providers. If a value appears unusual, check whether the change persists and consult the provider.
For emergency decisions, rely on official information from the relevant authorities.

Fukushima restricted zone: the web geometry is a high-resolution vector derived from the official Fukushima Prefecture evacuation-zone concept map (31 March 2025) and georeferenced through the JGD2011 ArcGIS evacuation-zone raster; narrow map-rendering seams between adjacent sections were closed and detached non-zone artifacts removed while mapped release exclusions were preserved; the latest status is checked against the METI evacuation-zone concept map (1 April 2026).
