Kokune Ltd. President Yasushi Kogune is not sure his 55-worker die-casting company will be able to survive until the slump brought on by the March 11 earthquake ends.

"The amount of work has continued to drop," lamented Kogune, 49, adding that he has no idea what will happen to the Hekinan, Aichi Prefecture-based business.

More than three months after the twin disasters, big name manufacturers, including hard-hit carmakers, are showing signs of recovery.
