hgo — Thu, 21 May 2026 06:58:27 +0000

We have recently confirmed that some guests who made reservations at Hotel Vischio Kyoto, a JR-West Hotels property, through Booking.com have received fraudulent messages via email and messaging apps. These messages request credit card information under the guise of booking confirmations and include links to phishing websites.

If you receive such a message or any suspicious communication, please do not access any links included in the message.

Please note that our hotels will never contact guests via WhatsApp, messaging apps, or social media regarding reservation or payment information.

We are currently working with Booking.com to investigate this matter further.
In addition, as part of our security measures, we have already taken the necessary actions, including changing the passwords for our Booking.com management system.

We sincerely apologize for any concern this situation may have caused our valued guests.
We kindly ask that you remain cautious regarding this matter.

Thank you for staying with JR-West Hotels.
In Japan and internationally, there have been reports of power banks (portable chargers) becoming dangerously hot or even catching fire.
To ensure your safety and that of all our guests, we ask that you follow the rules below for power bank use in guest rooms.

If leaving your room to go anywhere else, please unplug the power bank from all outlets first to ensure there is no risk of it catching fire.
If using the power bank to charge a mobile electronic device or if charging the power bank itself from a power source in the guest room, avoid charging in the following types of locations.
- Under direct sunlight, such as near a window
- On top of a flammable material, such as a bed, sheets, or curtains
Keep an eye on the power bank while charging.

To ensure there are no problems, please always ensure that you are close enough to keep an eye on the power bank while it is in use.

During your stay, if room service staff happen to notice that a power bank is being used under conditions such as the above while cleaning your room, they may unplug it and move it in the interest of safety. We appreciate your understanding and cooperation with these rules.

[Follow-up report] Possible leakage of customers’ personal information due to unauthorized access and delivery of messages leading to a phishing site

hgo — Tue, 18 Jul 2023 01:00:02 +0000

We deeply apologize to our customers and the involved parties for the concern caused by the unauthorized access to the accommodation reservation information management system (hereinafter referred to as “management system”) provided by Booking.com, which we used at our company, and by the distribution of messages to some customers that led them to a phishing site.
We would like to report on the facts that have come to light through our investigation since our previous announcement (June 1, 2023), as follows.

1. Investigation results (cause)

In cooperation with related organizations and specialized companies, we have been investigating the cause and details of the damage. As a result, we have determined that the cause of the unauthorized access to the management system was that one of our terminals that manages the system was infected with malware.

2. Investigation results (damage)

Incident①
Regarding the possibility of leakage of customers’ personal information (including credit card information) contained in the accommodation reservation information (for stays between May 1, 2022 and March 31, 2024), we have requested confirmation from Booking.com, the system provider, and have been received reports that there is no evidence of such a leakage.

Incident ②
Regarding the message sent to some customers with a URL link leading to a phishing site, we have not received any reports of damage at this time.
We ask that customers continue to exercise caution and, if they receive such a message, not to access the URL link attached to it.

3. Future actions and measures to prevent recurrence

Based on the results of the investigation and suggestions from related organizations, we introduced security tools and provided training to our employees. We will continue to further strengthen our measures.
In the unlikely event that a customer is confirmed to have been harmed by a personal information leak or phishing attempt in the future, we will promptly contact the relevant parties and take the necessary action.

[Important Notice] Apology and Notice regarding possible leakage of customers’ personal information due to unauthorized access and delivery of message leading to a phishing site

hgo — Fri, 02 Jun 2023 03:14:37 +0000

The hotel reservation information management system (hereinafter referred to as “management system”) of Booking.com, a company used by Hotel Granvia Osaka, was illegally accessed, and the possibility that personal information of some guests may have been leaked cannot be denied.
In addition, it has been confirmed that a message was delivered to some customers by a malicious individual that directed them to a phishing site.
We are still investigating the details of both cases, and deeply apologize for any inconvenience and concern this may cause to our customers.

1. Circumstances of the incident

On May 29, 2023, after receiving a report from Booking.com, we investigated and found that the management system was illegally accessed by a malicious individual.
In response, we immediately changed the login password for the management system and stopped accepting new accommodation reservations through Booking.com. However, we cannot deny the possibility that a third party may have accessed the personal information of customers stored in the management system.
It was also confirmed that messages with URL links leading to phishing sites were sent to some customers who had booked accommodation through Booking.com, using the chat function of the management system.
If you receive such a message, please do not access the URL link attached to it.
The cause of the unauthorized access is currently under investigation by the Company and related organizations.
We have not confirmed any leakage of personal information of customers who have made reservations through accommodation reservation information management systems other than Booking.com.

2. Incident Description

Incident①
It is possible that personal information (name, credit card information, address, and telephone number) of customers contained in accommodation reservation information (for stays between May 1, 2022 and March 31, 2024) via Booking.com, Inc. has been leaked.

Incident②
A message with a URL link leading to a phishing site was sent to some of the customers in Incident① via the chat function in the Booking.com management system.

3. Response to customers

Customers who fall under 2 above will be contacted from time to time to alert them in order to prevent them from being directed to phishing sites. For inquiries, please contact us through the following E-mail address.
