Thank you for choosing YAWN YARD Kouri Island.

We have received a report from Temairazu, Inc., the provider of our site controller system (a central management system for multiple booking channels), confirming that an unauthorized third party accessed their system.

As a result of this incident, personal information associated with some guest reservations may have been viewed or exposed, and suspicious messages or phishing emails pretending to be from our hotel have been sent to some of our guests.

Please review the current details, the response status and future measures taken by Temairazu, Inc., and contact information below.
