[Update - Important] Notice of Possible Personal Information Leak Due to Unauthorized Access to Our Third Party Reservation Management System, and Request for Caution

Thank you for your continued patronage of MARUFUKURO.

We have recently been informed that unauthorized access have occurred in the third party reservation management system the hotel uses (the site controller system "Temairazu"), and that guest personal information may have been viewed or leaked externally as a result.
We have already reported this matter to the Personal Information Protection Commission of Japan. In addition, security measures have been completed for the system component involved, and it is now operating normally and securely.
We would like to share the facts confirmed to date, along with important precautions we ask our guests to take.

■ Affected Reservations
Based on our investigation so far, we have confirmed that suspicious messages have been sent via the messaging app Whatsapp to guests holding reservations meeting the following conditions:

Reservation date: Reservations made on or before September 21, 2026

Stay date: Reservations for stays on or after September 21, 2026

■ Regarding Credit Card Information
The reservation management system affected by this incident does not handle or store credit card information. Therefore, no credit card information has been directly leaked from our hotel nor the third party system.

The activity currently being reported is a phishing scheme, in which fraudulent messages are sent to contact information obtained through this incident, directing recipients to an external website and attempting to have them enter their credit card details there.

■ Request to Our Guests (Important Precautions)

Our hotel will never request urgent payment or ask you to re-enter credit card information via SNS (such as WhatsApp) or other messaging services.
If you receive a suspicious message claiming to be from our hotel or accommodation (by email, SMS, WhatsApp, etc.), please take the following precautions:

Do not click any URLs or links included in the message

Do not enter your credit card details or personal information

Do not reply to the suspicious message

Do not make any payment or money transfer as instructed in the message

If you wish to confirm your reservation details, please contact our hotel directly or the official support desk of the booking site you used

■ If You Have Already Entered Information or Made a Payment

If you have already entered your credit card details on a suspicious website, please contact your credit card company immediately to request that your card be suspended, in order to prevent unauthorized use by a third party.

In addition, to help us understand the scope of this situation, we would greatly appreciate it if you could also contact the emergency inquiry desk.
