Department store chain Takashimaya Co. said Monday that employees at its store in Nihonbashi, Tokyo, have lost a customer list containing information on 14 people, making it the 10th case of customer data loss since last year.
Takashimaya officials said they will improve the handling of customer data, noting the latest case has not yet led to the leak of data to a third party.
According to Takashimaya, the customer list apparently disappeared between March 18 and last Friday in the store's women's clothing section.
On the list were 14 customers' names, addresses and the amounts they purchased, the officials said, adding the list was supposed to be used for direct-mail marketing.
On Friday, Takashimaya announced another case of data loss involving 32 customers at the maternity section of its outlet in Osaka's Nanba district.
The Nihonbashi case surfaced after Takashimaya instructed all outlets to check the management of customer data following the Osaka leak.
