I 'm planning to go to Tokyo next week. Is it safe to go there? my concern is radioactivity radiations.?

Question:

Answer:

Not a good idea to go there right now. There are still rolling blackouts. There are shortages of food items like milk and bread. Also things like frozen foods are in short supply.
There's more to be concerned about other than radioactivity.
EDIT : well over 150,000 people have left Japan since the earthquake !
