Let'sgotoseeHIda-Ontake Lava Flow!

We’re aiming for Hida-Ontake Lava Flow to be qualified as a Geopark.

At Hida-osaka, you can find precious stories with a history of 60,000 years
that go far beyond your imagination.

We (Hida-osaka Tourist Association) promote Hida-osaka’s tourism industry by revitalizing local resources, including Mt. Ontake’s eruption, lava flow with a length of 15 kilometers, waterfall walking trails that are registered as the first treasure of Gifu, and carbonated springs that are rare and valuable in Japan. We will promote Gifu’s resources to become a well-known treasure all over Japan to let more people appreciating its rich nature.

Lava flow

Lava flows are streams of molten rocks that flood the land surface like a river, instead of being broken pieces, when a volcanic eruption occurs. The form of lava flows depend on the magma’s quality and quantity. While smooth textured lava flow can form a volcanic dome, mildly textured lava flow can form volcanic sheets like at the foot of Mt. Fuji. Mt. Ontake has the latter one.

Lava flow 
at Kusakidani Gorge of Mt. Ontake

Mt. Ontake is formed by many layers of ejecta, such as a lava flow. The lava flow at Kusakidani Gorge streamed from Marishitensan peak and covered up Hyouedani area about 60,000 years ago. It stretches about 15 kilometers up to around Gantate area now.

Magnificent natural views that will deeply move your heart.

What is a Geopark?

A Geopark is a natural heritage site containing geological and terrain features, rocks, volcanos, and faults. Its territory should be protected and be used for geological research and nature-human relationship education. It can revitalize local attractions as tourism resources or educational places for science or disaster prevention.
