BBC One HD

The earthquake and tsunami which hit Japan on 11 March left 21,000 people dead in a matter of minutes.

Six months on, Panorama's Paul Kenyon travelled to Okawa to meet survivors and to hear how the tsunami swept away the local school, killing 74 of the 108 children.

Naomi Hiraska explains her decision to continue the search for the body of her 12-year-old daughter, Koharu.
