The mountain's grassy slopes are maintained through annual controlled burns, known as 'yamayaki', to prevent forest encroachment.
The rotating observation tower at the summit makes a full 360-degree turn approximately every 13 minutes.
The mountain was formed by volcanic activity that occurred roughly 300,000 years ago.
The slopes of Mt. Kanpu are a designated site for paragliding due to the consistent coastal wind patterns.
From the summit on a clear day, the snow-capped peak of Mt. Chokai is visible to the south.
Mt. Kanpu is a 355-meter dormant volcano located on the Oga Peninsula that features a distinct three-peak profile and expansive panoramic views of the Sea of Japan and the Ota Lake. The mountain is covered in bamboo grass, which creates a treeless, golden-hued landscape that changes color with the seasons. It features a rotating observatory at its summit that provides a 360-degree view of the surrounding peninsula. The mountain is part of the Oga Quasi-National Park and serves as a primary geographical landmark for the Oga region. Geologically, it is recognized for its unique volcanic topography, which differs significantly from the surrounding forested mountains.
The grassy ridge lines leading toward the summit observatory offer the best perspective of the volcanic topography.
Bring a windbreaker as the summit is consistently exposed to strong coastal gusts.
Utilize the binoculars provided in the observation deck for detailed views of the Hachirogata Lagoon reclamation area.
Check local weather reports specifically for wind speed before planning a paragliding or outdoor photography session.
Do not attempt to hike up the main motor road as it lacks pedestrian paths and has high-speed vehicle traffic.
The rotating observatory may close during periods of extreme high winds or heavy winter snowfall.
Stay on marked trails to protect the delicate grassland ecosystem; do not pick the native vegetation.
