History
The Okhotsk service was first introduced by Japanese National Railways from the start of the revised timetable on 22 September 1959, as a semi-express service operating between  and , using KiHa 22 2-car DMUs, with five return workings daily. From July 1960, services were extended to Sapporo, and ran coupled with Sōya semi express services over the Hakodate Main Line. From the start of the revised timetable in October 1961, services were upgraded to "Express" status, and were operated using KiHa 56 4-car DMU formations, including a KiRo 26 Green (first class) car. From the start of the revised timetable on 2 October 1972, services were upgraded to "Limited express" status, and were operated using KiHa 80 series DMU formations. From the start of the revised timetable in November 1986, the KiHa 80 series rolling stock was replaced with KiHa 183 series 6-car DMUs. Sleeper service

From 1992, the former  express overnight sleeper service was integrated with the Okhotsk (becoming Okhotsk 9 & 10), featuring a SuHaNeFu 14-500 series sleeping car sandwiched in the DMU formation. From March 2006, this became a seasonal-only train (Okhotsk 81 & 82), and the overnight service was discontinued entirely from 16 March 2008. SL Okhotsk
