Nestled among the Kuju Mountain Range and Aso-Kuju National Park, Hatchobaru Power Plant uses geothermal energy from volcanic heat to generate electricity, making it the largest geothermal power plant in Japan.

Geothermal power utilizes steam from underground to produce electricity via the power of nature.

Through panels and videos, the exhibition hall adjacent to the power plant offers an introduction to the mechanisms and types of geothermal power.

Visitors can also go on a guided tour of the power plant, accompanied by a staff member.

Experience the power of geothermal energy firsthand by hearing the sound of turbines spinning and observing the rising steam.

The plant's expansive grounds are home to wildlife such as wild boars, raccoons, cuckoos, and wagtails. In addition, clusters of Kyushu azaleas and rhododendrons bloom seasonally, allowing visitors to enjoy the changing scenery throughout the year. Amidst all of this nature, this eco-friendly power plant demonstrates how nature’s gifts can be harnessed to produce sustainable energy.

Nearby, the Komatsu Jigoku area offers a view of natural steam vents and bubbling mud pools along scenic trails.
