Hiroshi Kainuma thinks a lot about Fukushima. He's written a number of books and held hundreds of lectures on the crisis since 2012, but these days, he's concerned with the public's perception of his hometown.

Kainuma is a sociologist, born in Iwaki, Fukushima Prefecture, a city located about 30 km south of the crippled Fukushima No. 1 nuclear power plant.

During more than 200 lectures he's interacted with thousands of people, giving him an insight into what they think, and perhaps more telling, how they feel, about the prefecture and its people.
