JAL reported that a network issue began Thursday morning, affecting both internal and external systems.
The airline identified the cause of the issue as an attack designed to overwhelm its network with excessive data traffic, leading to system failure or unresponsiveness.
JAL reported that the cyberattack did not use a virus and did not compromise customer data. However, it caused delays of over 30 minutes for 24 domestic flights as of late morning.
The cyber attack targeted only JAL; Japan’s other major airline, ANA Holdings, was not affected, a spokesperson told the Associated Press.
Other airlines, like All Nippon Airways, Skymark Airlines, and Star Flyer, have not faced any cyberattacks.
Earlier in the day, Chief Cabinet Secretary Yoshimasa Hayashi, the top government spokesman, said at a press conference, “Through the transport ministry, we have requested JAL to repair its system as soon as possible to respond appropriately to affected customers.”
