Omuroyama was born in the eruption of approximately 4000 years ago. This pretty pudding-shaped mountain was formed by the accumulation of scoria (low-viscosity ejecta splashed out from the crater). If you climb up to the top of the mountain by the lift, you will get a superb view of the Sagami Sea, the Izu Islands, Mt.Fuji, Mt.Hakone and Izu Tobu Volcanic Group.

  • Start: Omuroyama Lift Station

    A 6-minute walk in the air to the top of the mountain by the lift

  • Omuroyama

    Omuroyama is the largest scoria cone in Izu Tobu Volcano Group. From its summit you can see various unique monogenic volcanoes such as Komuroyama, Lake Ippekiko, Yahazuyama, etc. You can also overlook a variety of landscapes created by the lava flow from Omuroyama Volcano like Izukogen(lava plateau) and the the Jogasaki coast.

  • Sakura no Sato: Scoria Raft

    Sakura no Sato at the foot of Omuroyama Volcano is a park constructed on the gentle landform of lava flow effused from Omuroyama. In spring it is filled with cherry blossoms in bloom. In this park you can see a unique natural product of lava called "Scoria Raft". When the scoria was carried on top of the flowing lava, and tumbled through the lava flow, it got lava congealed on its side. The Scoria raft draped in layers of lava just like an omelette was thus created.

  • Sakura no Sato: Ananohara Lava Cave

    Ananohara Lava Cave is an open topped lava tunnel made by Omuroyama lava flow. The ceiling of the tunnel collapsed and formed a vertical hole. If you look down from the top of the cave, you will see thick layers of rocks on the wall. To observe layers, you will surely understand that the lava flow flowed several times.
