Question:

What is the current state of radiation in Japan, Is it safe for a 1 month holiday in Tokyo?

Its hard to get current information of the current state of the radiation threat. Would going
to Toyko and sourrounding areas snowfields for a period of 1 - 2 months have any lasting lasting effect on ones health in the long term, AT ALL?

Answer:

There is now, and never has been a radiation problem in Tokyo. The only off limits area is within a 20km radius of the Fukushima nuke plant(s). Tokyo is over 150 miles south of them.
