Apology and Notice Regarding Personal Information Leakage Due to Unauthorized Access to Our Contractor’s Email Distribution Service (Second Report)

Overview and Current Status

Published as the second report on November 4, 2026, we disclose the investigation results and responses concerning personal information leakage due to unauthorized access to a contractor's email distribution server. The affected period was from October 10, 2026 to October 31, 2026, and it has been confirmed that the only information leaked was email addresses. Individual notifications were sent to the 305 affected customers on November 5. We have suspended the affected email distributions and are migrating to a secure separate platform, and we will continue to strengthen our information security framework. Although the incident occurred after the second quarter of the fiscal year ending March 2027, there is no impact on the results for that period and no incorporation into the full-year forecast at this time.

Impact and Future Measures

We take this matter seriously and will monitor and re-evaluate our information security framework, including that of contractors. We will strengthen the framework including contractors as a recurrence prevention measure and will appropriately report to the Information Protection Committee. Restoring customer and market trust is our top priority, and we will promptly disclose the status of our responses going forward.
