okay look i want to go japan for my birthday super super bad. So,i just want to know if it's safe to tarvel there. Is it?
lily, it depends on where you want to go, if it's within 20 kms of the Fukushima nuclear plant, then NO. But if you're talking about Osaka then YES. If it's Tokyo then its significantly and mostly yes, with some doubts about what affects there'll be from long term residence (and the evidence while divided seems to be that there is low level contamination).
Have a look at this other Ask A Nomad post on the issue.
