Japan Air Lines established a subsidiary called Japan Asia Airways to operate flights to Tokyo. Before the completion of the second runway at New Tokyo International Airport (now Narita International Airport) near Tokyo, Japan, airlines from Taiwan were required to fly to Tokyo International Airport (commonly known as Haneda Airport) in order not to offend the airlines from the PRC that flew to Narita. All Nippon Airways, however, used an existing subsidiary, Air Nippon. With the implementation of a new Japan-Taiwan air agreement, JAL and ANA took over flight operations between Japan and Taiwan in April 2008.
