Mount Ibuki is one of the 100 Famous Japanese Mountains and is recognized for its unique botanical diversity, including over 1,300 species of alpine plants.
The summit holds the world record for the deepest snow ever measured at a weather station, reaching 11.82 meters in 1927.
The driveway is a private toll road, meaning it is operated independently of national or prefectural road maintenance systems.
The area is a recognized habitat for the rare Ibuki-Shoma (Cimicifuga japonica) and other endemic mountain wildflowers.
On clear days, the summit vantage point provides visibility as far as the Ise Bay and the central Japanese Alps.
The Ibukiyama Driveway is a 17-kilometer private toll road that ascends to the 1,260-meter summit of Mount Ibuki in Gifu Prefecture. It serves as the primary vehicular access point to the mountain, which is the highest peak in Shiga Prefecture and a prominent part of the Ibuki Range. The road features 17 distinct curves and rises over 1,000 meters in elevation from the base in Sekigahara. At the summit parking lot, visitors gain access to walking trails that traverse alpine flora and offer panoramic views of Lake Biwa and the Nobi Plain. The summit area remains significantly cooler than the surrounding lowlands, often maintaining a distinct mountain microclimate. It is part of the Ibukiyama-Ibi-Sekigahara Prefectural Nature Park.
