The Okhotsk (オホーツク, Ohōtsuku) is a limited express train service in Japan operated by the Hokkaido Railway Company (JR Hokkaido), which runs between Sapporo and Abashiri.[1] There are two services per day running in both directions, with the journey time taking approximately 5 hours and 30 minutes. Trains operate at a maximum speed of 110 km/h (68 mph).[1] It is named after the Sea of Okhotsk.[2]

Rolling stock

Okhotsk services are normally formed of 4-car KiHa 183 series diesel multiple unit (DMU) trains as shown below, with car 1 at the Sapporo and Abashiri end (train reverses at Engaru Station).[1][3] These trains are scheduled to be replaced by KiHa 283 series DMUs from fiscal 2022.[4]


All cars are non-smoking.[5]

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 Asahikawa and Abashiri, using KiHa 22 2-car DMUs, with five return workings daily.[2][6] From July 1960, services were extended to Sapporo, and ran coupled with Sōya semi express services over the Hakodate Main Line.[2]

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.[2]

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.[2]

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.[2]

From 1992, the former Taisetsu (大雪) 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.[7] From March 2006, this became a seasonal-only train (Okhotsk 81 & 82), and the overnight service was discontinued entirely from 16 March 2008.[8]

SL Okhotsk

JR Hokkaido operates seasonal SL Okhotsk services formed of 14 series passenger coaches hauled by a JNR Class C11 steam locomotive and assisted by a JNR Class DE15 diesel locomotive.[9]
