Let'sgotoseeHIda-Ontake Lava Flow!

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

We, the Hida-Osaka Tourist Association, promote tourism in Hida-Osaka by putting the spotlight on its local assets, including the eruption of Mt. Ontake, the lava flow with a length of 15 kilometers, waterfall walking trails that are registered as the number-one treasure of Gifu, and carbonated springs that are rare and precious in Japan. We hope that more and more people will appreciate Hida-Osaka’s rich natural wonders, and we wish for “Gifu’s Treasures” to become “Everyone’s Treasures.”

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. The lava flow at Mt. Ontake represents the latter.

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 down from Marishitensan peak and covered the Hyouendani 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.
