Japanese people face the urgent issue of an ageing society. But it's not only people who suffer. The problem extends to the abandonment of pets. More animals are left behind as owners become too old to care for them, or pass away.

Families across Japan are still struggling with the pain and sorrow caused by one of the world's worst plane crashes. When a Japan Airlines jumbo jet crashed into a mountain ridge northwest of Tokyo in 1985, 520 people lost their lives. Thirty years on, some of the victims' loved ones are only just starting to talk publicly.
