Regular passenger flights between Changchun city in Northeast China's Jilin province and Tokyo in Japan have officially resumed, with flight CZ623 taking off from Changchun Longjia International Airport on April 1 bound for the Japanese capital. 

Their return aims to provide more convenience for passengers visiting relatives, studying abroad and touring. The service is tentatively scheduled to fly once a week every Saturday, operating an Airbus A321. 

To ensure the smooth resumption of the flights, the Changchun Border Inspection Station contacted relevant units in advance to review the flight timetable and the individual situations of passengers – and coordinated port controls and the provision of service guarantees.
