Hakone Tozan Railway 2000 series trainset "St. Moritz" at Odawara Station in 2006

The section of the line from Odawara Station to Hakone-Yumoto Station began operating in 1919, with the current terminus of Gōra being reached in 1930. Since 2006, only Odakyū Odawara Line trains run on the section from Odawara Station to Hakone-Yumoto Station, as that section was converted from dual-gauge (standard and narrow) to just narrow-gauge. From Gora, travelers can continue up the mountain on the Hakone Tozan Cable Car.

The railway is capable of climbing one meter vertically for every 12.5 metres (41 feet) of horizontal distance, with a maximum gradient of 8%. The line traverses Fuji-Hakone-Izu National Park, so the line was carefully designed to limit the impact on the scenery. Due to the difficult topography, the line has three switchbacks used to ascend particularly steep sections.

The section of the line between Hakone-Yumoto and Gora was suspended in October 2019 due to heavy damage caused by Typhoon Hagibis.[1] On 9 July 2020, after repairs had been completed, test trains began running over the line and full service was restored on 23 July.[2][3]
