Almost every day around a dozen students seek out nurse Akemi Idogawa at their temporary junior high school in Minamisoma, Fukushima Prefecture, hoping she will help ease their trauma.

Many at the prefabricated school, in the city's Odaka district, also live in temporary housing, after they and their families were forced three years ago to flee their homes because of the meltdowns at the Fukushima No. 1 power plant.

Some of the kids tell Idogawa about their aches and pains. But when she offers them a bed to nap on, they usually prefer to sit and just talk.
