Norio Kimura, who lived 3 km south of the plant, had to choose between staying behind to search for his father, wife and younger daughter Yuna, or taking his mother and elder daughter away from spreading radiation.

"I was torn by having to abandon my search and leave them behind... By the time I came back, the situation had become quite grim when it comes to finding them alive," Kimura, 50, said.

The accident still hampers Kimura's effort to find Yuna, the last family member missing, as entry into half of his hometown, Okuma, is restricted due to high radiation levels.
