Japan Transocean Air (JTA)

Is Japan Transocean Air safe?

Yes. Japan Transocean Air (JTA), the Okinawa airline of the JAL Group, has not had a fatal accident since it began flying in 1967, and it has not lost an aircraft in more than 40 years. We score it 86, above its parent Japan Airlines (83) and just above Solaseed Air (85), which serves the same islands. The catch is on the ground: Japan's transport ministry has issued JTA two strict warnings in seven years, the latest in January 2026 over maintenance records that engineers had not written.

Which flights does JTA operate?

JTA flies 14 Boeing 737-800s on 16 routes, from Naha to Ishigaki and Miyako and from Okinawa to Tokyo Haneda, Osaka, Fukuoka and Komatsu. It carried 3.65 million passengers in the year to March 2026. JAL sells seats on many JTA flights, and JTA flies some JAL routes such as Haneda to Komatsu jointly with JAL. On its own NU flights, JTA talks to air traffic control as "JTA" (NU128 flies as JTA128). On the JL-numbered flights it flies for JAL, such as Haneda to Ishigaki, it uses JAL's call sign (JL973 flies as JAL973), according to Flightradar24 in October 2026. Its own crews and certificate fly both kinds, and because JTA also sells flights under its own designator, this page covers them all.

Many of the smaller islands are served by Ryukyu Air Commuter, a JTA subsidiary that flies its own turboprops as a separate company. Its flights carry NU numbers, but it holds its own certificate and is scored on its own page, not here.

What accidents has JTA had?

The Japan Transport Safety Board (JTSB) lists one accident in the last 20 years.

On 3 October 2022, flight 36 from Naha to Komatsu hit sudden turbulence in clear air at 41,000 feet and descended to 37,000 feet to get out of it. With the air calm again, the captain switched the seat-belt sign off so passengers could use the toilets. Minutes later, a strong sideways jolt caught a flight attendant standing in the aisle at the back, and she broke a bone in her right foot. The JTSB found the wind change could not have been predicted from the weather data the pilots had checked. ICAO rules count a serious injury as an accident, so it sits in the accident factor, but it weighs lightly.

The last time JTA lost an aircraft was on 26 August 1982, when the airline still flew as Southwest Air Lines. A 737-200 landed at Ishigaki, bounced, and ran off the end of the runway after the crew shut down both engines, which also disabled the anti-skid brakes. Everyone got out before it caught fire. That is far outside our 20-year window.

Why has the regulator warned JTA?

Two strict warnings fall inside our ten-year window, and they are the main reason JTA does not score higher.

The 2026 case weighs more. MLIT said the aircraft were airworthy, but it called the breaches deliberate and repeated by several engineers. It also said that JTA had missed them even after a general warning to all airlines in December 2024, so its audits and safety management were not working. JTA had to report its fixes by 27 February 2026.

What about runway incidents at Naha?

Naha is one of Japan's busiest airports, and Japan's air force shares it. Two serious incidents there involved JTA aircraft. In July 2019, an Asiana A321 entered the runway without clearance while a JTA 737-800 was on final approach; the tower sent the JTA jet around, and the JTSB put the cause on the Asiana crew. In June 2015, an air force helicopter crossed the runway in front of a departing ANA jet, and a JTA 737-400 landed while the ANA aircraft was still stopped on the runway, despite an instruction to go around. The JTSB found the JTA captain had judged he could stop in time. That case is now more than ten years old, so it no longer counts in our incident score.

What does JTA fly?

Only the Boeing 737-800, in a 165-seat layout with 20 Class J seats. JTA replaced its 737-400s with new 737-800s from 2016 and retired the last 737-400 in May 2019. A 13th aircraft joined in January 2020 and a 14th, leased from JAL, in 2023. JTA publishes no average age, but most of the fleet was built in the late 2010s. It is a reliable, widely flown type, though an older design without fly-by-wireFly-by-wireA flight control system in which the pilot's inputs go to computers, which then move the control surfaces. Many such systems also stop unsafe manoeuvres.More in the glossary controls, and we found no replacement order.

How to fly JTA safely

Keep your seat belt fastened whenever you are seated, even when the sign is off. The 2022 injury happened minutes after the sign went off in smooth air, and routes from Okinawa to the main islands cross long stretches of open sea where turbulence can come without warning. From about June to October, typhoons close Okinawa's airports at short notice. If JTA cancels or holds a flight, rebook rather than hunt for a seat on a marginal departure.

How we scored it

The accident record (94) has no deaths in JTA's history and no lost aircraft in more than 20 years. Oversight (90) reflects Japan's strong regulator and IOSA registrationIOSAThe IATA Operational Safety Audit, an international audit of an airline's safety management and operations. Every IATA member must pass it.More in the glossary. The fleet (76) is a single older-generation type, though mostly less than ten years old. Serious incidents (72) carry the 2019 and 2026 warnings, and the environment scores 82 for the island network and typhoons. Overall 86. Compare Skymark, another single-type 737-800 airline.
