Radiation Levels in Tokyo

The Tokyo Metropolitan Government has an English website dedicated to radiation-related information. It provides hourly radiation levels monitored at eight locations in Tokyo, including Shinjuku, Ota and Adachi wards, as well as the results of fallout, tap water and food sampling tests conducted by the metro government. The website also provides all of the past radiation readings Tokyo has monitored since 2011.
