KUMAMOTO, Japan - A panel exhibition opened Saturday in front of Kumamoto Castle to mark 10 years since a pair of major earthquakes hit the southwestern Japanese prefecture of Kumamoto, highlighting the efforts of craftsmen and city workers to repair damage to the structure.

The event, held in a plaza in front of the castle's main keep in the city of Kumamoto, explains surveys of damage to the stone walls and traditional wood-joinery repairs. Restoration is expected to finish in fiscal 2052.
