A Japan Post employee's bag containing personal information on 290,000 customers was stolen last month from a parked car in Soka, Saitama Prefecture, according to Japan Post.
On the night of Jan. 31, a bag belonging to a man who works at the Postal Savings Business Center in Saitama, was stolen from his car. The bag contained a USB flash memory data storage device that was found and recovered on Wednesday in Noda, Chiba Prefecture.
However, the memory device contained about 290,000 postal transfer account holders' names, addresses, account numbers and account opening dates as well as the names and account numbers of 31 postal savings account holders.
According to Japan Post, the data contained on the memory device would not allow a third party to withdraw cash because registered personal seals are required to make cash withdrawals.
