The area is geologically part of the Shikoku Karst, one of the three major karst landscapes in Japan.
Tengu-no-Mori, the peak located here, reaches 1,485 meters above sea level.
The location serves as a natural border, with the mountain ridge acting as the divide between Tsuno Town in Kochi and Kumakogen Town in Ehime.
The name 'Tengu' refers to legendary forest-dwelling spirits in Japanese folklore, often associated with steep mountain terrain.
The site hosts a unique ecosystem of subalpine plants that are rare in warmer lowland areas of southern Japan.
Tengu Highlands is a high-altitude plateau situated on the border between Kochi and Ehime Prefectures at an elevation of approximately 1,400 meters. The area features the Tengu-no-Mori forest, the highest point in the Shikoku Karst region. Visitors can access a network of trekking trails that traverse limestone outcrops and open pasture lands. During the winter, the site functions as a small ski resort known for its panoramic views of the Shikoku Mountains. The landscape is characterized by its dramatic Karst topography, which includes white limestone rocks scattered across emerald green meadows. It is a prominent segment of the Shikoku Karst Prefectural Natural Park. Weather conditions can change rapidly due to the high altitude, frequently leading to thick fog or clear, sweeping vistas of the Pacific Ocean and Seto Inland Sea.

Bring a windbreaker or layers, as temperatures are significantly lower than in the Kochi lowlands.
Wear sturdy, closed-toe hiking shoes to navigate uneven limestone terrain safely.
Check local weather alerts for fog, as visibility can drop to near-zero within minutes.
Do not attempt to drive the narrow mountain access roads in low-visibility conditions or heavy rain.
Ski facilities operate seasonally during winter months; mountain roads may close temporarily during extreme winter snowfall.
Stay on marked trails to protect the delicate alpine vegetation and avoid stepping on exposed limestone surfaces, which can be slippery.
