The Hakone Tozan Line (箱根登山鉄道線, Hakone Tozan Tetsudō-sen, lit. Hakone Mountain-Climbing Railroad Line) is a mountain railway in Japan operated by the Hakone Tozan Railway. This company belongs to the Odakyu Group, and also owns the Hakone Tozan Cable Car.

The section of the line from Odawara Station to Hakone-Yumoto Station started operations in 1919, with current terminus Gōra 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, visitors can continue up the mountain on the Hakone Tozan Cable Car.

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

The section of the line between Hakone-Yumoto and Gora was closed indefinitely in October 2019 due to heavy damage caused by Typhoon Hagibis.[1]
