DoubleBlue will be performing website enhancement for the reservation page on the night of March 31st 2025 due to the introduction of “3D Secure 2.0”. You will not be able to make reservations during the system downtime which takes about one hour. We apologize for any inconvenience this may cause and seek for your understanding.
With effect from April 1st 2025, you will need to re-register your credit card for reservations. Thank you in advance for your cooperation.
＊＊“3D Secure 2.0” is a system that verifies the identity of credit card users and prevents fraudulent use. “3D Secure 2.0” will be mandated by the Ministry of Economy, Trade and Industry from April 2025.
