[Important Notice] Beware of Suspicious Messages Impersonating "Booking.com"

2026.06.10

Dear Guests,

Thank you very much for your continued patronage of Keio Plaza Hotel Sapporo.

We have recently been informed of an ongoing issue where suspicious messages, falsely claiming to be from the accommodation booking platform "Booking.com," are being sent to guests via the messaging application WhatsApp.

These fraudulent messages typically state that "some reservation details are incomplete" or "your booking will be automatically cancelled unless updated within 24 hours," attempting to direct recipients to external, malicious websites.

Please be assured that Keio Plaza Hotel Sapporo will never contact our guests regarding reservations via WhatsApp or any other messaging applications.

If you receive such a suspicious message, please do not click on any links provided, and do not reply under any circumstances.

Regarding this matter, we have already requested Booking.com to investigate the situation thoroughly. Additionally, we are taking all necessary security measures within our hotel to ensure the safety of our guests' information.
We sincerely apologize for any anxiety and concern this may cause, and we greatly appreciate your vigilance and cooperation.
