Fukushima child's playtime starts with a fallout check
Ayaka and her family were forced to flee when their home was destroyed in the earthquake and tsunami which devastated parts of Japan in early 2011, killing about 16,000 people.
They live outside the 20km (12 mile) exclusion zone surrounding the failed nuclear plant at Fukushima Daiichi, but they still have to live with increased radiation levels which impact their lives.
Ayaka is one of several seven to 10-year-old survivors who talk about how their lives have changed forever in BBC Two's Japan - Children of the Tsunami on Thursday 1 March 2012 at 2000GMT - or watch later online (UK only) at the above link.
