TOKYO (Kyodo) — Major Japanese home furnishings retailer Nitori Holdings Co. on Monday said up to 37.62 million customer records may have leaked due to unauthorized access, becoming the latest domestic company to announce a possible data breach.

The information includes email and home addresses of both members of Nitori group and those who have purchased goods online, although login passwords and credit card information were not compromised.

Nitori said it confirmed the access on Friday. A third-party investigation discovered the breach had occurred between mid- to late October.

The company warned of phishing attempts and suspicious phone calls, while noting it would contact affected customers via mail or email.

Sega Corp. also announced the same day that about 2.2 million customer email addresses had been leaked after a contractor the gaming giant uses to send out email newsletters was compromised. Names, phone numbers, credit card information and login passwords were not included.

Sega said it has not confirmed any fraudulent use of the information, which was leaked due to unauthorized access to Arara Inc.’s system, but it warned customers of phishing attempts.
