Notice from Temairazu, Inc. Regarding a Potential Leak of Customers’ Personal Information
Thank you very much for your continued patronage of Hotel Sun Clover Misato.
We have discovered that, in “Temairazu,” the Reservation management system used by our Hotel, there may have been a leak of customers’ personal information to external parties. This was not due to unauthorized access to the Hotel, but rather unauthorized access to Temairazu Co., Ltd., the company that provides the Reservation management system.
Within the scope confirmed at this time, we have identified incidents in which suspicious messages were sent to some Reservers whose Reservations meet all of the following conditions:
・Reservation date: Reservations completed on or before September 21, 2026
・Stay date: Reservations with stay dates on or after September 21, 2026
*As of September 28, 2026, the cause has been identified and measures to address it and strengthen security have been implemented. Reservations can now be made normally.
If you receive any suspicious contact (email, SMS, etc.) claiming to be from Mori Eight Co., Ltd., our operating company, or from an Accommodation provider, please take special care regarding the following.
Emails from our Hotel will only come from the domain “@sunclover.net.” We will not send messages from any other email address.
[Important precautions]
・Do not open any URLs or links included in the message
・Do not enter credit card details or personal information
・Do not reply to suspicious messages
・Do not make payments or transfers by following instructions in such messages
・If you need to Check Reservation details, contact either your reserved Accommodation directly or the official support desk of your accommodation booking website
