We were told that in some parts of Gunma, radiation levels rose as high as 3.2 µSv/h.  A Tokyo-based international school reported that Minakami has deemed not safe to conduct this year's adventure fieldtrip.  In response, they arranged for a more westerly location.

While we agree that those levels are elevated, they are in no way health concerning.  Though rest assured, we're happy to announce that according to our own readings, the Mt. Haruna base hasn't seen any elevated levels yet.  Readings are unchanged at around 0.2 µSv/h since March 11.

We'll however restart our regular tests up at Mt. Haruna just to be on the safe side.  Below a screenshot of independent readings taken from the region.  The official ground radiation data can be accessed here.
