Thank you for choosing Koshikano onsen.
Unauthorized access has been confirmed in the reservation management system “TEMAIRAZU,” provided by Temairazu, Inc. (listed on the Standard Market of the Tokyo Stock Exchange; securities code: 2477). This system is used by our resort and many other hotels and inns to manage accommodation reservations.
According to the company’s announcement, some guest information managed in the system may have been viewed or obtained by a third party as a result of this unauthorized access. The investigation is ongoing.
We sincerely apologize for the concern and anxiety caused by this incident involving a system used to manage our guests’ reservations.
■ Current Status
Temairazu, Inc. has announced that it identified the cause of the unauthorized access and implemented the necessary measures and security enhancements. The temporarily suspended functions have also been restored, and the company reports that the system is currently operating normally.
The company does not handle credit card information, and its system does not store such information. However, if you enter your card details on a website linked from a suspicious message, those details may be obtained by a third party. Please remain vigilant.
