Just heard on the news (excerpted from the news story):
"More than 5,700 safes that washed ashore along the coastline have also been hauled to police stations by volunteers and rescue crews.
Inside the safes officials found about $30million in cash. In one safe alone, there was the equivalent of $1,000,000.
Other contained gold bars, antiques and other valuables.
Japan’s National Police Agency said nearly all the money found in the areas worst hit by the tsunami has been returned to its owners."
