More than a year ago, an earthquake and tsunami in Japan caused one of the worst nuclear disasters in history.

Now the Japanese government says radiation levels are sufficiently low in the danger zone near the Fukushima nuclear facility, and some people have begun returning home.

But in the city on Minami Soma, 18km from Fukushima, there is still no electricity or running water, and high levels of radiation have seeped into the fields surrounding the town.
