There are direct trains heading to the Jōgasaki coast from Tōkyō.
Get on the “Odoriko” Limited Express train at Tōkyō station, bound to Shimoda Station, and it will arrive to Izu peninsula in about one hour (there are also trains from Shinjuku station). Get off at Izu Kōgen Station or at Jōgasaki Kaigan Station. The Japan Rail Pass covers partly this route, as there is a section on a non JR line. However, the Japan Rail Pass Kanto version covers also the non JR section.
The walking trail s 30-40 minutes walking from Izu Kōgen Station.
At Jōgasaki station you can take a “Tōkai-bus”, which will reach Izu Kōgen in about 10 minutes.
