Apology and Notice Regarding the Temporary Suspension of the One Harmony Member System
We sincerely apologize for the significant inconvenience and trouble caused to our members over this extended period.
Due to the implementation of a new member system, we are requesting that you reset your passwords. During the system update, we have strengthened security and enhanced the protection of your member information. However, a malfunction occurred in the integration of some systems during this information protection effort, causing prolonged inconvenience to our customers.
Therefore, in order to repair the malfunction in the integration of various systems, modify some programs, and conduct re-testing, we will temporarily suspend the sign-up and sign-in functions from May 1st to May 18th.
We sincerely apologize for the inconvenience caused to our members.
[Services Unavailable During the Suspension Period]
* Signing in to your member account
* Booking member accommodation plans for domestic and international hotels after signing in
* New membership applications
* Online point exchange (Stay Awards, exchange for common vouchers, exchange of miles and points (Note))
(Note) Exchange for common vouchers, exchange of miles and points, etc. are scheduled to resume from late May onwards. The exact resumption date will be announced separately.
During the suspension period, we have prepared member accommodation plans that can be booked without signing in. Please make your reservations through our official website.
Points, accommodation history, and mileage accrual associated with hotel use will continue. Stay Awards for telephone reservations and point payments at hotels will also remain available.
We would like to reiterate that there have been no incidents of personal data leakage due to targeted attacks or other incidents related to this matter.
We will continue to strive to improve our system environment and services to ensure a comfortable user experience.
We are working diligently to ensure the resumption of the sign-up and sign-in functions on May 19th, and we appreciate your understanding.
One Harmony Support Team
