Mount Imanoyama is located on the border between Tosashimizu City, the southernmost city on Shikoku Island, and Mihara Village in Hata County, which is a neighboring city to the north.
Mt. Imanoyama is the source of water for the people, animals, and plants that live in this area. The rivers that flow from this mountain enriches the fields and the environment in the village of Mihara. Mihara Village, which sits at the foot of the mountain, is well known for its delicious rice and vegetables, and its production of local specialties such as yuzu (a yellow citrus fruit) and doburoku (a traditional Japanese homebrewed concoction). Eventually, the rivers flow out to the Pacific Ocean, leading to the rich fishery that the city of Tosashimizu is famous for.
Overlooking Tatsukushi Underwater Park (now Tatsukushi Sea Area Park), which was appointed as Japan’s first under water park in 1970, Mt. Imanoyama has been an essential part of this nature-themed tourist attraction. In 2001, torrential rains hit the area and caused landslides in the surrounding hills and devastated the waters surrounding the park. However, as a result of several initiatives to improve the environment of the mountains, rivers, and the sea based on the Law for the Promotion of Nature Restoration (as of 2021), the sea has recovered to a healthy condition to the point where corals are once again growing and colorful fish are swimming.
In the midst of this situation, a plan to build a wind-power generation station has been proposed which would include a total of 45 gigantic windmills (36 of which would stand 200 meters high and 9 are proposed to be 150 meters in height) and be constructed in the mountains and forests in and around Mt. Imanoyama.
To implement this plan, approximately 50 hectares of national forest, which presently serves as a wildlife sanctuary, would be cut down and miles of wide roads built to accommodate large trucks and heavy machinery needed to transport wind turbine parts. The result would be a clear-cut of tree stumps and dusty topsoil. However, if such roads are built along the ridge of the mountain, muddy waters would flow out to the sea through the rivers after each rain, causing the sea to become muddy and destroying the marine environment again.
 
Mt. Imanoyama is also home to a wide variety of flora and fauna, including specific plant communities listed in the Kochi Biodiversity Strategy. The Tosashimizu Salamander, which is classified as endangered in Kochi Prefecture, and the rare Mountain Hawk-eagle are included in this document. Additionally, this area is an important habitat for the Japanese squirrel, an indigenous species in Japan.
In 2019, a campground (Snow Peak Tosashimizu) opened in this area, followed by the opening of Umi no Wa, the Ashizuri-Uwakai National Park Tatsukushi Visitor Center and the Satoumi, the new Kochi Prefectural Ashizuri Aquarium in 2020. Kochi Prefecture has been engaging in tourism promotion with the tagline, “The entire Tasukushi area is a natural park and aquarium.”
Is this wind power project really necessary for the people who visit this area for its abundant nature, or for the local residents who live here? In light of the principles underpinning the “Geopark” concept that the City of Tosashimizu has been promoting, it is clear that the wind power project is inappropriate.
In order to preserve this rich nature for the next generation and to continue living in this area, we demand that Mt. Imanoyamato should remain as it is now: unspoiled.  We choose to live in the shadow of Mt. Imanoyama where we can experience its charm, rather than under giant windmills that will be out of operation in less than 20 years.
We would like to take this opportunity to reaffirm the importance of the mountains and to continue our efforts to ensure that human activities do not destroy this precious nature.　
We would very much appreciate your cooperation in our efforts to stop the wind power construction project on Mt. Imanoyama.
