Ōzora (train)
The  is a limited express train service between  and  in Hokkaido, Japan, operated by Hokkaido Railway Company (JR Hokkaido). There are six trains per day running in both directions, with the fastest journeys taking 3 hours 58 minutes.

History
The service commenced as the limited express  on 1 October 1961, operating between Hakodate and Asahikawa using KiHa 80 series DMUs with one return working daily. The service was extended to run between Hakodate and Kushiro from 1967. By 1973, there were three return workings daily. In October 1980, following the opening of New Chitose Airport, services were reorganized, with just one return working daily between Sapporo and Kushiro. From October 1981, the train was rerouted via the Sekishō Line, reducing journey times by approximately one hour. From 22 March 1997, four Ōzora services were upgraded to become  following the introduction of new KiHa 283 series tilting DMUs. The remaining Ōzora services using KiHa 183 series DMUs were phased out by 2001. KiHa 261 series DMUs were introduced on 14 March 2020, and the service has since been returned to simply Ōzora.
