Warning: Beware of suspicious messages impersonating our Hotel via WhatsApp or other messaging apps.
Thank you very much for your continued patronage of Kai Hotel.
We have received a report that, in “Temairazu,” the Reservation management system used by our Hotel, there may have been an external leak of guests’ personal information.
Based on what has been confirmed so far, we have identified incidents in which suspicious messages were sent to Reservers via messaging apps such as WhatsApp for some Reservations that 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
We sincerely apologize for the significant inconvenience and concern this may cause.
If you receive any suspicious contact claiming to be from our Hotel (email, SMS, etc.), please take extra care regarding the following:
[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 the message
- If you wish to Check Reservation details, please contact either the Accommodation you reserved or the official support desk of your booking site
If you have entered credit card information on a suspicious website, please contact your credit card company immediately.
Please note that the system involved does not handle or store credit card information; therefore, no credit card information has been leaked.
A release from Temairazu Co., Ltd. regarding this matter is available on our Hotel’s official website.
