Personal information on some 250 people was accidentally made public on a Web site run by home builder Mitsui Bussan House-Techno Inc., company officials said Monday.
The information included names, addresses and other details relating to people who asked Mitsui Bussan House-Techno for brochures through its home page, the officials said, adding that the company had erased the data by Saturday morning.
Law enforcement authorities have recently urged companies to improve the management of their Web sites following a series of leaks of personal data, such as that on some 50,000 people released on a home page operated by Kommy Corp., a beauty-treatment service firm.
Mitsui Bussan House-Techno, a wholly owned subsidiary of trading house Mitsui & Co., said the information leak was caused by security problems relating to the management of its server and that it will review the way it accepts requests for brochures on its Web site.
