On January 21, 2025, Marukai Corporation, operating as Tokyo Central, appeared on the leak site of the lynx ransomware group. The company, founded in 1965 as one of the first Japanese retailers in the United States, had internal files exfiltrated following a ransomware attack. While the exact number of people affected remains unknown, anyone who has shopped at its stores, joined its loyalty program, or provided contact details may have personal information now at risk.

What Public Reporting Shows
Public reporting indicates that lynx claims to have stolen internal files from Marukai. The data was posted on the group’s leak site at lynxblog.net. No specific volume of records has been disclosed, and the precise contents of the files have not been independently verified by third parties. Available reporting describes the incident as a classic ransomware operation involving both encryption of systems and subsequent data exfiltration.
Marukai Corporation has not yet issued a public statement confirming the breach or detailing what customer or employee information was contained in the stolen files. This lack of transparency leaves many ordinary customers uncertain about their exposure.
Why This Matters for You and Your Family
When a retailer like Tokyo Central suffers a breach, the information at stake is rarely limited to order history. Internal files often contain names, addresses, phone numbers, email addresses, and payment details tied to loyalty accounts or past transactions. If your family has ever filled out a membership form, entered a sweepstakes, or paid with a card at one of their locations, some of that data may now be in attackers’ hands.
