The Ōzora (おおぞら) is a limited express train service between Sapporo and KushiroinHokkaido, 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.^[1]

History[edit]

The service commenced as the limited express Ōzora (おおぞら) 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.^[2] From 22 March 1997, four Ōzora services were upgraded to become Super Ōzora (スーパーおおぞら) following the introduction of new KiHa 283 series tilting DMUs.^[1] 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.^{[citation needed]}

2011 derailment and fire[edit]

On 27 May 2011, the Super Ōzora 14 service from Kushiro to Sapporo was brought to an emergency stop inside the 685-metre-long (2,247 ft 5 in) No. 1 Niniu Tunnel in Shimukappu, Hokkaidō, at around 21:55 after car number 2 of the 6-car formation became derailed. The train caught fire, and all of the 245 people on board, including train staff eventually evacuated the train. 39 were treated for smoke inhalation and minor burn injuries.^[4] The burnt-out train was removed from the tunnel on 29 May 2011.^[5]
