[Important] Beware of suspicious emails pretending to confirm a Cancel the Reservation request.
Thank you very much for your continued patronage of Matsumoto Tourist Hotel.
We have discovered that, in “Temairazu,” the Reservation management system we use, there may have been a leak of customers’ personal information to external parties. We sincerely apologize for the significant inconvenience and concern this may cause.
Based on what has been confirmed so far, we have identified cases in which suspicious messages were sent to Reservers for some Reservations that meet all of the following conditions:
・Reservation date: Reservations completed by September 21, 2026
・Stay date: Reservations with stay dates on or after September 21, 2026
If you receive any suspicious contact (email, SMS, etc.) claiming to be from us or an Accommodation, please take extra care and note 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 as instructed by the message
・If you need to check Reservation details, contact the official support desk of the Accommodation you booked or your booking website
If you have entered credit card information on a suspicious website, please contact your credit card company immediately. Please note that the system involved in this incident does not handle or store credit card information.
