Emergency Landings Across Japan Have Led Way to Major Safety Issues Concerning the Travel Chaos Effectuated by Flights: What You Need to Know

Published on January 7, 2026

Japan’s aviation safety is renowned, with emergency landings being rare. Between January 2022 and December 2025, key incidents included Jetstar Japan flight 501’s bomb threat and United Airlines flight 32’s cargo-hold fire warning. Japan Airlines Flight 585 declared a Mayday due to low fuel reserves in July 2023, while Flight 516 collided with a Japan Coast Guard plane at Haneda in January 2024. Fortunately, nearly 400 passengers safely evacuated. In 2025, technical issues prompted several precautionary returns, including Spring Airlines flight JL8696’s pressurisation issue and Philippine Airlines PR102’s smoke in the cabin. The Haneda runway collision in 2024 stands apart, showcasing effective crew training despite a fire. Each incident was rigorously investigated by the Japan Transport Safety Board (JTSB), with lessons fueling ongoing improvements in aviation culture, crew training, and infrastructure.

Few events in 2022

The JTSB’s 2022 register contains no cases of commercial airliners making emergency landings in Japan. The incidents recorded for that year involve turbulence‑related injuries and ground mishaps rather than inflight emergencies requiring diversions.

2023 – Bomb threat and fuel shortage

Jetstar Japan Flight 501 (7 January 2023) – While flying from Narita to Fukuoka, Jetstar Japan Flight 501 received a bomb threat. The pilots declared an emergency and diverted to Chūbu Centrair Airport. After landing, they ordered an evacuation using slides. The JTSB report states that one passenger was seriously hurt and four others sustained minor injuries; no bomb was found and the aircraft was undamaged.

Japan Airlines Flight 585 (12 July 2023) – Japan Airlines Flight 585, a Boeing 767 with 258 people on board, attempted two approaches to Hakodate in poor weather. Concerned about fuel reserves, the crew declared “Mayday Fuel” and diverted to New Chitose Airport. The aircraft landed safely without injuries. Investigators later recommended improved fuel‑planning procedures for regional airports.

2024 – Runway collision and precautionary return

Japan Airlines Flight 516 (2 January 2024) – The most serious incident of the period occurred when JAL Flight 516, an Airbus A350, collided with a Japan Coast Guard DHC‑8 on the runway at Tokyo Haneda. The interim investigation report notes that there were 379 people on the A350, including two pilots in training, a supervising pilot, nine cabin crew and 367 passengers. Moments after the main gear touched down, the flight crew saw a small turboprop on the runway and a collision followed that ruptured fuel tanks and ignited the wide‑body jet. Despite the impact and subsequent fire, the captain and cabin crew managed to organise an emergency evacuation using the forward slides. With the public address system inoperative and the evacuation command device damaged, crew members relied on shouted instructions and hand signals to keep passengers calm and to direct them away from exits threatened by flames or sparks. All occupants escaped; one passenger was seriously injured. Five of the six Coast Guard personnel on the smaller aircraft died. The accident prompted reviews of runway‑incursion prevention, crew resource management and air‑traffic control procedures.

Japan Airlines Flight 2154 (22 June 2024) – Later that year, a regional Embraer 170 operating as JAL Flight 2154 returned to Aomori shortly after departure because of engine‑system warnings. There were 47 people aboard. The flight landed safely and no injuries were reported; maintenance inspections followed.

2025 – Technical faults, smoke, fire warning and wildlife

Spring Airlines Japan / JAL 8696 (1 July 2025) – A Boeing 737 operating under Japan Airlines flight number JL 8696 encountered a pressurisation system alert during a flight from Shanghai to Tokyo. The crew notified air traffic control and descended rapidly. Oxygen masks deployed and the flight diverted to Kansai International Airport, landing without incident. Authorities reported that there were 191 occupants and no injuries.

Philippine Airlines Flight PR102 (10 April 2025) – Philippine Airlines flight PR 102 from Manila to Los Angeles detected smoke emanating from an air‑conditioning unit soon after take‑off. The crew decided to divert to Tokyo Haneda, where the aircraft landed around 3:30 a.m. with 359 people on board. Passengers remained on the aircraft for several hours until arrangements were made. The Philippine transport ministry coordinated with Japanese authorities and ordered the airline to explain the cause.

United Airlines Flight 32 (12 September 2025) – United Airlines Flight 32 from Tokyo Narita to Cebu received a cargo‑hold smoke warning. The pilots declared an emergency and diverted to Kansai Airport. After landing, an evacuation via slides was ordered. Two passengers sustained minor injuries during the evacuation; maintenance checks found no evidence of fire.

All Nippon Airways Flight 639 (13 October 2025) – All Nippon Airways Flight 639 returned to Tokyo Haneda shortly after take‑off for Iwakuni because the crew believed the nose gear had contacted a runway light. The Boeing 737 landed safely with 168 passengers; inspections later found damage to the nose gear. No injuries were reported.

Japan Airlines Flight JL646 (14 November 2025) – JAL Flight 646, a Boeing 767 departing Kagoshima, ingested birds into its No. 2 engine during climb. Following bird‑strike procedures, the pilots declared an air turn‑back, held to burn fuel and returned to Kagoshima. The flight carried 258 passengers and crew, all unharmed. The incident temporarily closed the runway and diverted other flights.

Japan Airlines / Hokkaido Air System Flight 2823 (11 December 2025) – A Saab 340 operated by Hokkaido Air System under a JAL flight number experienced an engine failure after take‑off from Sapporo Okadama. Pilots shut down the faulty engine and diverted to Hakodate, where all 26 passengers and crew landed safely. Authorities suspected ice ingestion as a contributing factor.

Reflections and trends

The small number of emergency or precautionary landings over four years testifies to the robustness of Japan’s aviation safety system. Threats or abnormal indications are taken seriously, as illustrated by the Jetstar bomb scare and United cargo‑hold warning; both resulted in immediate diversions and slide evacuations even though no bomb or fire was present. Fuel management was central in JAL 585’s diversion, showing that crews will declare an emergency when reserves are in doubt. The Haneda collision stands apart as a catastrophic accident that nonetheless showcased effective crew training: despite a runway incursion and post‑impact fire, nearly 400 people escaped. Technical warnings in 2024‑25 prompted precautionary returns, while natural hazards such as bird strikes and icing led to safe air turn‑backs. Each event was investigated by authorities, generating recommendations that will help prevent similar occurrences. These lessons support ongoing efforts to strengthen safety culture, improve crew and air‑traffic training, and modernise infrastructure across Japan’s aviation system.
