A JAL Japan Airlines Airbus A350-900, registration JA02XJ performing flight JL-521 from Tokyo Haneda to Sapporo Chitose (Japan), was descending through FL250 towards Sapporo about 80nm out of Sapporo when the crew suddenly lost communication with air traffic control due to the failure of all their radios.
