Typhoon Roke has struck disaster-ravaged Japan and is on course to hit Fukushima, where engineers are still struggling to bring a nuclear plant under control after the March tsunami.
There are concerns that rain could force radioactive water into the sea.
Across Japan more than a million people were urged to evacuate their homes; an advisory was later lifted in one area but 330,000 people remain at risk.
