Is it safe to go Japan this Summer?

Question:

My family planned to go Japan for this spring, but after the radiation problems, we postponed our trips to japan for summer. Is it safe to go Japan in summer than spring of this year?

Answer:

It depends.
On what will happen in Fukushima in the next few months. Because that's how long it will at least take until they know if they get it under control.
And it depends on where you are going.
Remember that the area 30km around tchernobyl is still officially not inhabitable and will be for the next few hundred years.
And be aware that whole cities were swept into the sea and more than 10000 people died. It will be a long time for Japan to recover, if ever.
