I'd agree that him doing even further research is good, but that article doesn't address the "thing" he appears to be talking about. He's asking whether it's safe to go to Japan at all, not whether the crisis is still real. Of course it's still a thing. The question is whether it's safe for someone to visit anywhere in the entire country of Japan, and the clear answer is yes. For a short-term visitor that isn't going anywhere near Fukushima, there is little to no threat. It is safe to visit Japan.
