Sustainable Living Woven by the Heat of the Earth

As the world moves toward carbon neutrality, countries are accelerating the adoption of renewable energy sources that emit little to no CO₂. However, the rapid development of solar and wind power has, in some cases, led to environmental concerns such as landscape alteration and ecosystem disruption. In contrast, geothermal energy offers a sustainable solution: it operates reliably 24 hours a day, year-round, regardless of weather conditions. Moreover, because many geothermal sites are located near national parks, their development has proceeded with careful consideration for environmental preservation.

Hachimantai City has a long history of utilizing its abundant natural resources. Nestled deep within the Matsukawa Onsen area stands the Matsukawa Geothermal Power Plant, Japan’s first commercial geothermal facility. In 2019, the Matsuo-Hachimantai Geothermal Power Plant began operations near Gozaisho-numa Pond, and in the same year, construction commenced on the Appi Geothermal Power Plant at the northern foot of Mt. Appi. This latest facility started commercial operations in March 2024, marking a new chapter in the city’s geothermal innovation.
In the 1970s, the Matsukawa Geothermal Power Plant began supplying steam to nearby hotels, giving birth to the unique hot spring known as Magma no Yu (“Bath of Magma”). Today, more than 700 hotels, ryokan inns, pensions, and even hospitals and welfare facilities benefit from its healing waters. Adding to this legacy of innovation, the steam rising from Matsukawa has also inspired a distinctive craft: Geothermal Dyeing, a rare dyeing technique that harnesses natural geothermal steam to create colors found nowhere else.
In Hachimantai, the blessings of geothermal energy extend far beyond power generation, evolving into unique sustainable experiences. Visitors can explore Geothermal Dyeing, where the Earth’s heat transforms fabric into one-of-a-kind creations; discover Geo Farm Hachimantai, where food byproducts are recycled as feed for horses; and visit Hachimantai Smart Farm, where geothermal energy enables year-round cultivation of fresh, pesticide-free vegetables. These initiatives embody a harmony of nature, tradition, and innovation—offering travelers a rare opportunity to experience how geothermal power shapes a sustainable future.

The Earth’s Heat Painting Nature’s Palette — GEOCOLOR

It may be hard to believe, but the technique of Geothermal Dyeing was discovered entirely by chance at the Geothermal Dyeing Laboratory. Today, it is recognized as an exceptionally rare dyeing method, unparalleled anywhere else in the world.

One of the remarkable features of this technique is its ability to create an astonishing variety of colors by harnessing the heat and unique composition of geothermal steam. As the dye penetrates the fabric under high-temperature steam, trace amounts of hydrogen sulfide in the vapor can sometimes interact with the dye, causing partial fading. This simultaneous interplay of coloring and bleaching produces enchanting, otherworldly patterns, unlike anything seen in conventional dyeing methods.

In Geothermal Dyeing, the dye penetrates deeply into the fibers of the fabric, making the shibori (tie-dye) technique particularly crucial. By carefully stitching and binding sections of the cloth, artisans guide the flow of the dye, creating intricate and visually stunning patterns that emerge naturally through the interaction of geothermal steam and fabric.
It may come as a surprise, but the daily variations in geothermal steam can significantly influence the final outcome of each dyeing session. In addition, numerous other factors affect how the dyes interact, ensuring that no two pieces of fabric ever turn out the same. Every pattern is truly one-of-a-kind—this is the essence of GEOCOLOR.

Geothermal-Powered Agriculture for the Future

At Hachimantai Smart Farm, geothermal energy is harnessed to maintain a stable growing environment year-round, allowing for the cultivation of fresh, pesticide-free vegetables. Visitors can experience a next-generation, sustainable form of agriculture that makes the most of nature’s own power.
In Hachimantai City, Iwate Prefecture, where the shortage of agricultural workers is a pressing challenge, innovative approaches are underway to revitalize the region by combining its natural energy resources with cutting-edge cultivation techniques and IoT-controlled systems. Previously unused greenhouses, left idle due to an aging population, have been repurposed for a basil cultivation project heated with thermal water supplied by a geothermal power plant. Drawing on expertise and technology from Tokyo and Fukuoka, this initiative exemplifies a new style of agriculture that blends tradition, innovation, and sustainability.
