Rakuten Inc. confirmed Thursday another personal data leak involving consumers who shopped at an imported goods store in its Internet mall.

Japan's largest online shopping mall operator said the leaked data include credit card numbers, names, addresses and phone numbers relating to 161 people. The company asked credit card companies to monitor any illegal use of the cards, though there have been no such reports so far.

Combined with an earlier data leak pertaining to 123 shoppers who purchased goods from AMC, a shop selling imported merchandise operated by American Merchandise Concept Inc. in Tokyo, the total number of shoppers affected comes to 284. The number is expected to rise further as the store has taken 94,000 orders since it signed up with the Rakuten site in March 2002.
