we are heading to hukuba at the end of the year and i just wanted to make sure it was going to be ok. have there been any recent high readings from here. and what about the food and water supply
Nagano prefecture was unaffected by the earthquake, tsunami or radiation leak from the failed Fukushima plants. There have been no elevated levels of background radiation as far as I can find.
This blogger ( independent of government) confirms this here http://hakuba.wordpress.com/2011/08/02/radiation-levels-in-japan-2/
I don't think there's any reason to be concerned. Habuka is a long way from Fukushima and you ahve the entire japanese Alps in between for protection. over 6 years ago
