Thank you very much for always staying at Guesthouse Chura Kukuru Ishigaki Island.

TEMAIRAZU Co., Ltd. has announced that unauthorized access by a third party was detected in the "TEMAIRAZU" reservation management system used by our facility to manage reservation information, and that some guest information may have been viewed or obtained by a third party.

We sincerely apologize for the considerable concern and inconvenience this has caused our customers.

[Reservations That May Be Affected]

Based on what we have confirmed so far, we have identified an issue where suspicious messages are being sent to customers for some reservations that meet the following criteria.

・Reservation Date: Reservations confirmed by September 21, 2026

・Stay Date: Reservations for stays on or after September 21, 2026

At this time, Mehanai Co., Ltd. is continuing to investigate the specific details and scope of the information that may have been viewed or obtained by third parties.

[Please Be Wary of Suspicious Messages]

Suspicious messages have been identified in which senders pose as lodging facilities or booking sites and, via messaging services such as WhatsApp and WeChat, email, and SMS, request the following information:

・Confirm and Finalize Accommodation Reservations

・Re-enter your credit card information

・Urgent payments and money transfers

・Accessing suspicious websites

If you receive a message like this, please pay close attention to the following points.

・Do not open any URLs or links included in the message

・Do not enter credit card information or personal information

・Do not reply to suspicious messages

・Do not make payments or transfer money based on the instructions in the message

We will never suddenly ask you to re-enter your credit card information or make an urgent payment or money transfer via WhatsApp, WeChat, SMS, or any other means.

If you need to verify your reservation details, please do not reply to suspicious messages or click on any links contained in them. Instead, please contact our facility or the official customer service channel of the booking site where you made your reservation directly.

[If You Accidentally Entered Your Credit Card Information]

In the unlikely event that you have entered your credit card information or other details on a suspicious website, please contact your credit card company immediately to verify your card activity and discuss the necessary steps to take.

According to a statement released by Temairazu Co., Ltd., the “TEMAIRAZU” series does not process credit card information, and no credit card information is stored within the system.
