When professional boxer and model Tomomi Takano heard that children in Fukushima Prefecture were becoming unfit and overweight because the 2011 nuclear crisis limited the time they could play outside, she decided to use her skills to help.

Last month, the glamorous 27-year-old taught some 200 junior high school students in the village of Otama an indoor workout based on boxing moves.

"They really concentrated on the boxing and tried hard," she said at a recent U.N. conference hosted in Sendai about disaster risks. The boxer hopes to run more sessions in Fukushima to improve children's agility and provide an outlet for their emotions.
