The Hisatsu Line is a railway line operated by Kyushu Railway Company (JR Kyushu), connecting Yatsushiro Station in Yatsushiro City, Kumamoto Prefecture, with Hayato Station in Kirishima City, Kagoshima Prefecture. It is classified as a local railway line. The section between Yatsushiro Station and Yoshimatsu Station is also known by the nickname “Ebino Kogen Line.”
The Hisatsu Line is the only railway route that runs through all three prefectures of southern Kyushu: Kumamoto, Miyazaki, and Kagoshima. It has played an important role in local transportation and has also become a major tourism resource thanks to its spectacular scenery, historic stations, and distinctive railway engineering.
The railway’s history began in 1901, when the route opened as part of the Kagoshima Line, the predecessor of today’s Kagoshima Main Line. At that time, it provided a railway connection between Yatsushiro and Kagoshima.
In 1927, a new railway route following the coast opened, and the original inland route came to be known as the Hisatsu Line. The name combines “Higo,” the former name of the province that corresponds to present-day Kumamoto Prefecture, and “Satsuma,” the former province corresponding to present-day Kagoshima Prefecture.
Later, the section between Yoshimatsu and Hayato became part of the Nippo Main Line, while the route from Yatsushiro to Hayato remained known as the Hisatsu Line. The railway is especially distinctive for its beautiful views along the Kuma River and its mountain section, where trains negotiate a loop line and switchbacks to climb steep terrain.
The Hisatsu Line has also attracted attention as a sightseeing railway. After the express service “Ebino” was discontinued in 2000, tourist trains such as SL Hitoyoshi, Isaburo-Shinpei, and Hayato no Kaze were introduced to showcase the scenery along the route.
Historic wooden station buildings, views of the Kuma River, and the railway’s unusual switchback sections have made the line particularly popular with railway enthusiasts and travelers seeking a memorable journey through southern Kyushu.
The basic specifications of the Hisatsu Line are as follows.

Following the partial opening of the Kyushu Shinkansen in 2004, the Hisatsu Line’s value as a sightseeing route increased. Steam locomotives and tourist trains operated along the line, attracting visitors interested in both railway travel and the natural scenery of the region.
At the same time, the railway has served as an everyday means of transportation for local residents. The section between Yoshimatsu and Hayato, in particular, has been used by students commuting to school and by people traveling to work.
The route between Yatsushiro and Hayato can be divided into three principal sections. Each has its own landscapes, railway features, and historical attractions.
The section between Yatsushiro and Hitoyoshi is known as the “River Route,” or Kawa-sen, because it follows the Kuma River. The railway passes through beautiful valleys and along the riverbanks, offering views of the rugged landscape of southern Kumamoto.
Along the way, passengers can see the former site of Arase Dam, which was removed in 2018, as well as Setoishi Dam. Bridges crossing the river and railway tracks winding through deep gorges are among the route’s most memorable features.
The area is also known for Kuma River boat trips and rafting. Depending on the location and conditions, travelers may see people enjoying these activities from the railway or from viewpoints along the river.
The section between Hitoyoshi and Yoshimatsu crosses the Kunimi Mountains and is known as the “Mountain Route,” or Yama-sen. It is particularly famous among railway enthusiasts for the switchback at Okoba Station, its loop line, and the climb over Yatake Pass.
One of the best-known features is the view from the Yatake Pass area. The scenery has been counted among Japan’s Three Great Train Window Views, with panoramic vistas extending toward the Kakuto Basin and the Kirishima mountain range.
The railway’s engineering is also part of the attraction. The switchback and loop line allow trains to negotiate steep mountain terrain, creating a journey that is as interesting for its railway design as it is for its scenery.
Between Yoshimatsu and Hayato, the railway passes through rural landscapes. This is the busiest section of the Hisatsu Line in terms of local use, particularly during the morning and evening commuting periods, when students and residents travel between their homes, schools, and workplaces.
Two stations along this section, Osumi-Yokogawa Station and Kareigawa Station, retain their original wooden station buildings dating from the railway’s opening period. Both buildings are registered Tangible Cultural Properties of Japan and are valued for their historic architecture.
Train operations on the Hisatsu Line have generally been divided into service sections centered on Hitoyoshi Station and Yoshimatsu Station. The line has used one-person train operation, with drivers handling services on their own in accordance with the railway’s operating arrangements.
In the past, services included the express train “Ebino” and the limited express “Oyodo.” Tourist trains later became an important part of the line’s appeal, alongside its role in local transportation.
One of the best-known tourist trains associated with the Hisatsu Line was SL Hitoyoshi. The steam locomotive had previously operated on the Hohi Main Line as “SL Aso BOY” before being restored and introduced on services between Kumamoto and Hitoyoshi in 2009.
According to the source article, the train operated mainly on Fridays, Saturdays, Sundays, and public holidays. It became popular with railway enthusiasts and sightseeing visitors who wanted to experience the atmosphere of steam-powered travel while enjoying the landscapes of Kumamoto and the Kuma River basin.
The Hisatsu Line has a distinctive place in the history of railway travel in southern Kyushu. Its origins as part of the Kagoshima Line, its later development as a separate route, and its role in connecting Kumamoto, Miyazaki, and Kagoshima have made it important both to local communities and to regional transportation.
The River Route offers views of the Kuma River and its dramatic valleys, while the Mountain Route is famous for its loop line, switchback, and panoramic views from Yatake Pass. The rural section toward Hayato adds another dimension, with traditional wooden station buildings that preserve the atmosphere of early railway travel.
Tourist trains such as SL Hitoyoshi, Isaburo-Shinpei, and Hayato no Kaze helped introduce the region’s landscapes and railway heritage to a wider audience. For travelers interested in Japanese railways, historic stations, and the natural beauty of southern Kyushu, the Hisatsu Line represents a remarkable combination of engineering, history, and scenery.
