We sincerely apologize to our customers and other related parties for the inconvenience and concern caused.
Background etc.
It has come to our attention that a third party may have gained unauthorized access to the system we use to manage hotel reservations by using the login ID and password for this facility.
At this time, we have received reports from the system manufacturer that they have found no traces of cyber-attacks or virus infections. Our facility is also currently investigating the possibility of a computer virus infection. The personal information that may have been leaked is that of customers who made reservations via an overseas booking site.

Future Actions
We will take measures such as reporting the incident to government agencies, deleting login IDs where unauthorized access was confirmed, and strengthening system security within our company.
We ask that all customers be extremely cautious about receiving unfamiliar SMS messages, emails, and fake sender names.
In the future, please be cautious of direct mail or fraudulent phone calls that may lead you to believe that we are the sender. In all other cases, please delete the email without opening any attachments or clicking on any URLs in the text.
We would like to once again apologize to our customers and all other concerned parties for the inconvenience and concern caused.
