History
Tonosawa Station opened on 21 October 1920 on the Hakone Tozan Line, 7.1 km from Odawara. The station, sandwiched between two tunnels, has two opposed side platforms accommodating three-car trains; the original level crossing at the Odawara end was rebuilt as an overhead staircase during platform extensions, and the Odawara-side turnout was relocated inside the tunnel. The station is permanently unstaffed and tickets must be purchased from the conductor on board; only a simple PASMO IC gate is provided. On 1 April 2024 operations passed to Odakyu Hakone as part of the wider Odakyu Group restructuring of Hakone services.

Notes
A small Zeniarai Benten shrine on the inbound platform was donated by the early-Showa stockbroker Fusakichi Matsui, founder of Matsui Securities; the shrine's annual festival falls on the birthday of his son, the firm's second president, on 10 May.
