Japan Airlines's origins date to October 1, 1953 when the Japanese government approved the creation of a state-owned airline. In 1954, the newly-formed carrier began its first international operations with transpacific flights to the United States. After three decades of service and expansion, the airline was fully privatized in 1987. In 2002, Japan Airlines merged with Japan Air System, the country's third-largest carrier. As of 2008, Japan Airlines carries 50 million passengers annually, and the airline plus its associated divisions has 17,925 employees as of 2007. Japan Airlines is also accredited with IATA's Operational Safety Audit for its safety practices.

Japan's flag carrier operates a long-haul fleet of Boeing 747, 767, and 777 aircraft on international routes, and utilizes Airbus, Boeing, and McDonnell Douglas aircraft for short-haul operations. The airline's freight division, JAL Cargo, flies a fleet of Boeing freighter aircraft. JALways, the airline's tourist subsidiary, operates flights to Polynesia and Southeast Asia. Japan Airlines's six domestic subsidiaries, Hokkaido Air System, JAL Express, J-Air, Japan Air Commuter, Japan Transocean Air, and Ryukyu Air Commuter operate feeder services and short-haul routes to secondary destinations.
