10.75 km Hakone crater-rim toll road balancing Lake Ashi against Mount Fuji.

The Ashinoko Skyline is a 10.75 km toll road completed in 1962 that runs north–south along the outer western rim of the Hakone caldera, climbing from 846 m at Hakone Pass to just over 1,000 m below Mount Mikuni before dropping to Lake Ashi, from National Route 1 near Hakone Pass to Kojiri above the northern shore of Lake Ashi. The ridge gives Lake Ashi to the east and, in clear weather, Mount Fuji, Suruga Bay and the Izu Peninsula to the west. It is a paid toll road on an exposed crater rim, prone to fog and a Hakone enthusiast favourite alongside the nearby Turnpike.
