ATR announced:
Japanโs startup airline TOKI AIR completed its first commercial flight to Sado Airport with an ATR 42-600, operating into the shortest commercial runway in the world served by an ATR 42-600.
Measuring at 890 metres, Sado Airport is not just another destination on the map. It is a highly constrained operating environment on an island off the coast of Niigata Prefecture. One where air connectivity can make a tangible difference for residents, businesses and visitors, yet where operational limitations mean that only a handful of aircraft can safely operate.

That is what makes this first commercial flight so significant. Serving Sado requires the right combination of airline expertise, careful preparation and aircraft performance. The ATR 42-600 is among the largest commercial aircraft types able to serve the airport, reflecting ATRโs proven ability to connect demanding regional destinations, including those with runways below 1,000 metres. In a region also known for strong winds, its 45kt crosswind capability provides additional operational flexibility, helping make commercial connectivity possible where infrastructure constraints would otherwise limit access.
Sadoโs runway environment also highlights the importance of aircraft certification and airport infrastructure working together. The runwayโs grooved surface, designed to improve water drainage and runway conditions, supports safe operations in challenging environments. ATR has specifically certified the wet grooved runway performance on the ATR 42-600, helping to unlock this type of operation and enabling regional operators to serve airports with demanding characteristics.
Connecting Sado Island
Taking its inaugural flight at the end of May, this milestone marks a new chapter in the airlineโs mission to improve regional connectivity across Niigata and beyond, as from the outset, connecting Sado has been a key priority.

TOKI AIR takes its name from the toki, the Japanese crested ibis, a bird closely associated with Sado Island, where major conservation efforts have helped restore its population. That link gives this first commercial service an added resonance: an airline named after one of the islandโs most emblematic symbols now helping reconnect it by air.
For Sado Island, the launch of commercial service means easier access to the mainland, stronger links for local communities, and new opportunities for mobility, tourism and economic activity.
In a protected island environment, the role of regional aviation is not only to connect, but to do so responsibly. With the lowest fuel burn, COโ emissions, and noise footprint in its class, the ATR is uniquely well-suited to meet Sadoโs essential connectivity needs.
With this first commercial flight to Sado Airport, TOKI AIR and the ATR 42-600 have demonstrated what regional aviation can achieve when the right aircraft meets the right mission.
This is where regional aviation delivers its full value: not only by flying communities efficiently, but by enabling the connections that matter most.
