I booked a flight to Osaka and Tokyo for mid-April next month, will it be safe to go to both places?

Question:

I would really like to go without cancelling my ticket or planning a later trip. Or should I just go to Osaka not Tokyo. I'm also scared that the radiation might land in Tokyo.

Answer:

I'm near Osaka, it's fine. Kansai has been unaffected by the triple disaster. Currently advice says non-essential trips to Tokyo and Tohoku should be avoided, mostly due to transport problems, but this may change before April.
