Mount Tenbo

Mount Tenbo is a lava dome in Kamishihoro that rises about 1,174 meters (3,850 feet) with steep slopes covered in dense vegetation and volcanic rock. The geological structure creates distinctive shapes and surfaces visible from many angles.

The lava dome formed through volcanic processes near the Kikai Caldera, which erupted about 7,300 years ago. This volcanic activity shaped the landscape that visitors see today.

The lava dome shapes the local landscape that hikers encounter directly, with its volcanic form dominating the surroundings. The steep slopes and their plant life show how nature has reclaimed this volcanic terrain over time.

Hiking trails are accessible through established transportation routes and offer varying difficulty levels through volcanic terrain. It is wise to wear sturdy footwear and bring water and snacks before starting the hike.

Scientists regularly study the lava dome's structure to understand magmatic movements and potential volcanic activity in the region. These ongoing observations give visitors a sense of living geological processes at work.
