Geology and Landscape of Shirakami Sanchi
The geological foundation of Shirakami Sanchi dates back approximately 90 million years to the Cretaceous Period, when granite was formed. Later, volcanic activity beneath the sea between approximately 20 and 12 million years ago created layers of tuff, mudstone, sandstone, and other rocks.
These geological processes helped create the rugged mountainous landscape seen today. The elevation ranges from around 300 meters to Mount Mukaishirakami, which reaches 1,243 meters. Deep valleys, steep mountain slopes, forests, waterfalls, and lakes create a landscape with remarkable variety.
The entire mountain region covers approximately 130,000 hectares, of which around 17,000 hectares are included in the World Heritage site. Approximately 74 percent of the broader region lies in Aomori Prefecture, with the remainder extending into Akita Prefecture.
The World Heritage area is divided into a strictly protected core zone and surrounding buffer areas. Development is highly restricted in order to preserve the area’s natural environment.
The Name and History of Shirakami Sanchi
The region was once also known as the Kosei Mountain Range. Local people have long been familiar with these mountains, and historical records by the Edo-period traveler and scholar Sugae Masumi refer to an area known as “Shiragami-ga-take.”
This name is believed to be one of the origins of the modern name “Shirakami Sanchi.” During the 20th century, the name became increasingly widespread through local movements opposing road construction and large-scale forest development. It was eventually adopted officially in administrative documents.
The history of Shirakami Sanchi is therefore closely connected not only with the natural environment but also with the efforts of local communities and citizens to protect the ancient forest.
Juniko: The Twelve Lakes
One of the most popular destinations within the Shirakami Sanchi area is Juniko, or the Twelve Lakes. Despite its name, the area actually consists of a group of approximately 33 ponds and lakes surrounded by beech forest.
The lakes are believed to have been formed by a major earthquake in 1704. Today, they are among the most scenic places to visit in the Shirakami Sanchi region.
Aoki: The Mysterious Blue Pond
The most famous lake is Aoki Pond, or the Blue Pond. Its striking cobalt-blue surface creates an almost surreal contrast with the surrounding green forest.
The water is remarkably clear, allowing visitors to see fallen beech trees beneath the surface. At the same time, the water has an intense blue color reminiscent of ink, creating one of the most mysterious and photogenic landscapes in northern Japan.
Wakitsubo Pond
Wakitsubo Pond is another beautiful blue-water pond in the Juniko area. The spring water flowing from the pond has been recognized as one of the Famous Waters of Aomori Prefecture and was also selected among the 100 Famous Waters of the Heisei Era.
The combination of crystal-clear water, ancient beech trees, and peaceful forest trails makes this area particularly appealing to travelers looking for a quiet and immersive experience in nature.
Juniko-an: A Peaceful Place to Rest
Juniko-an is a small teahouse located beside Ochiguchi Pond. During the appropriate season, visitors can enjoy matcha green tea and traditional sweets prepared using water from Wakitsubo Pond.
The simple tea experience provides a pleasant break during a forest walk. Sitting quietly beside the pond while surrounded by trees offers a peaceful way to appreciate the atmosphere of Shirakami Sanchi.
Japan Canyon: A Dramatic Scenic View
On the way toward Juniko, visitors can stop at a scenic viewpoint known as Japan Canyon. Over countless years, erosion has exposed the pale rock surfaces of the mountains, creating striking white cliffs among the surrounding vegetation.
The landscape has been compared to the famous Grand Canyon in the United States, although on a much smaller scale. The contrast between the bright rock faces and the surrounding green forest makes Japan Canyon a memorable viewpoint for hikers and photographers.
Forest Therapy Trails
The Juniko Forest contains several designated forest therapy trails, allowing visitors to choose a route according to their available time and fitness level.
Recommended Walking Routes
- Aoki Pond and Wakitsubo Pond Course
- Kanayama Pond Short Course
- Kanayama Pond and Itahata Pond Long Course
- Oike Pond Course
These trails provide opportunities to walk through ancient beech forests while enjoying the fresh air, quiet surroundings, clear water, and changing scenery. Even visitors who are not experienced hikers can enjoy the atmosphere of the forest by choosing a suitable route.
Morino Bussankan Kyororo
Morino Bussankan Kyororo is located near Juniko and serves as a convenient base for hiking and trekking in the area. The facility offers light meals and local souvenirs, making it a useful place to stop before or after exploring the forest.
Local buses also operate from JR Juniko Station, making the area accessible even for travelers without a car. Visitors can use the facility as a convenient rest stop during their exploration of the surrounding mountains.
Juniko Refresh Village
Juniko Refresh Village is a campground located near the lakes of Juniko. Visitors can stay in log cabins or at tent sites while enjoying the natural surroundings.
The traditional-style log cabins, built using Finnish red pine, provide a comfortable way to experience the forest without giving up the atmosphere of an outdoor adventure.
The campground is within walking distance of Juniko, making it a convenient base for travelers who want to spend more time exploring the Shirakami Sanchi area.
The Natural Environment of Shirakami Sanchi
Primeval Beech Forests
The greatest symbol of Shirakami Sanchi is its vast natural beech forest. The forest began taking its present form after the end of the last Ice Age approximately 10,000 years ago, and by around 8,000 years ago it had developed into a forest landscape similar to what can be seen today.
Many beech forests in Europe and North America were dramatically affected by glaciers during the Ice Age. The Japanese archipelago, however, was not covered by continental glaciers, allowing its forest ecosystems to survive and develop over thousands of years.
One particularly valuable area is the beech forest around Todaira, near Mount Futatsumori and Mount Masugadake. The forest retains an exceptionally natural character and has experienced relatively little human disturbance.
The fact that such a large-scale forest ecosystem has remained intact for thousands of years is one of the main reasons Shirakami Sanchi has outstanding global conservation value.
Remarkable Plant Diversity
More than 540 species of plants have been recorded in Shirakami Sanchi. In addition to beech trees, the forests contain large specimens of katsura, Japanese hop-hornbeam, keyaki, and other native trees.
The forest floor is often covered with dense stands of Chishima bamboo grass. Unlike many forests in other parts of Japan that have been converted into managed plantations, the forests of Shirakami Sanchi retain much of their original natural structure.
The area’s rugged terrain and strict conservation policies have played an important role in protecting this exceptional ecosystem.
Wildlife in the Ancient Forest
Shirakami Sanchi is home to approximately 4,000 species of living organisms. The diversity of birds, mammals, insects, plants, and other organisms reflects the health and complexity of the ancient forest ecosystem.
Among the most notable birds is the black woodpecker, a nationally protected species that nests in the beech forest. The area is also home to rare birds such as golden eagles, mountain hawk-eagles, and harlequin ducks.
Mammals
Mammals living in the region include the Japanese black bear, Japanese serow, and Japanese macaque. Shirakami Sanchi is particularly important as a habitat for Japanese macaques, which have a limited distribution in Akita Prefecture.
Visitors should never feed wild animals. The reappearance and spread of Japanese deer in recent years has also raised concerns about their potential impact on the forest ecosystem.
Insects
More than 2,300 species of insects have been recorded in Shirakami Sanchi, including species that are extremely rare and some that were previously unknown to science.
This extraordinary insect diversity demonstrates how the ancient beech forest supports a complex web of life extending from the forest canopy to the soil beneath visitors’ feet.
Conservation and Environmental Challenges
Since its designation as a World Natural Heritage Site, the core area of Shirakami Sanchi has been subject to strict environmental protection. Development and logging are prohibited, while hunting and other activities are also heavily regulated.
These conservation measures have helped preserve the ancient forest, but they have also created difficult questions concerning traditional livelihoods and local culture. For example, the traditional Matagi hunters, who have lived in harmony with the mountain environment for generations, have faced restrictions on hunting activities within protected areas.
Finding a balance between strict nature conservation and the continuation of traditional mountain culture remains an important challenge.
Climate change and invasive species are additional concerns. Protecting Shirakami Sanchi is therefore not simply a matter of preserving a beautiful landscape; it also requires long-term monitoring of the ecosystem and careful consideration of how humans interact with the natural world.
Exploring Shirakami Sanchi
Hiking and Walking Trails
Shirakami Sanchi offers a variety of hiking and nature-walking routes. Depending on the location and trail, visitors can experience everything from relatively easy forest walks to challenging mountain climbs.
Among the mountains particularly known for their scenery are Mount Tengu, Mount Kogake, Mount Futatsumori, and Mount Shirakami. These mountains provide opportunities to experience sweeping views of the surrounding forests and rugged terrain.
However, visitors should be aware that the core World Heritage area is subject to strict access restrictions. Many established hiking trails are concentrated on the Aomori side, while access from the Akita side may be restricted depending on the route and conservation regulations.
Before setting out, travelers should always check the latest information concerning trail conditions, access restrictions, weather, and seasonal closures.
Mount Shirakami

Mount Tayumine
Mount Tayumine can be reached via the Hitotsumori Nature Observation Trail. The route is popular with intermediate hikers and provides excellent opportunities to observe the rich forest environment.
The trail is particularly suitable for travelers who want to focus on nature observation rather than simply reaching a mountain summit.
Tsugaru Pass and the Mother Tree
Tsugaru Pass is a well-known access point for exploring the Shirakami Sanchi area. A trail leads from the pass toward Takakura Mountain, and the location can be reached relatively easily from Hirosaki by bus during suitable seasons.
One of the area’s former symbols was the Mother Tree, a beech tree estimated to be around 400 years old. Unfortunately, the trunk was broken by a typhoon in 2018. Even so, the Mother Tree remains an important symbol of the ancient forests of Shirakami Sanchi.
Anmon Falls
Anmon Falls is a spectacular group of three waterfalls located within the buffer zone of the World Heritage area.
The Anmon Gorge Trail provides access to the waterfalls. From the parking area and bus stop, the first waterfall can generally be reached in about 30 minutes, while reaching the third waterfall takes approximately one hour each way, depending on conditions.
The route itself is an attraction, as hikers pass through beautiful beech forest and can observe the area’s rugged natural landscape at close range.
Mount Futatsumori
Mount Futatsumori stands at approximately 1,086 meters. The trailhead provides relatively quick access to the World Heritage area, and the mountain is popular among visitors seeking panoramic views of the surrounding Shirakami mountains.
The combination of a manageable approach and spectacular scenery makes Mount Futatsumori an appealing destination for experienced hikers.
Tsurubeotoshi Pass
Tsurubeotoshi Pass lies on the border between Nishimeya Village in Aomori Prefecture and Fujisato Town in Akita Prefecture. It is particularly famous for its autumn scenery.
In fall, the green of the surrounding Japanese cedar forests contrasts beautifully with red, orange, and yellow foliage, creating a spectacular mountain landscape. The area can be reached by road, making it an attractive viewpoint for visitors exploring the region by car.
Dakedai Nature Observation Forest
Dakedai Nature Observation Forest is known for its enormous beech trees, some of which are estimated to be around 400 years old.
The forest has been developed as a place for environmental education and nature observation, allowing visitors to learn about the structure and importance of the beech ecosystem while walking among the trees.
Shirakami no Mori Yūzan-dō
Shirakami no Mori Yūzan-dō is a nature experience area located about 30 minutes by car from JR Ajigasawa Station. The forest has a long history of being protected as a source of water since the days of the Tsugaru domain.
Many beech trees more than 200 years old remain here. The walking trail is approximately 2.8 kilometers long and offers two main options, an outer loop and an inner loop.
Along the trail, visitors may discover signs of wildlife, including holes created by black woodpeckers and claw marks left by bears. One particularly interesting activity is listening to the sounds inside living trees using a special stethoscope.
These experiences offer an opportunity to observe the forest not simply as scenery but as a living ecosystem.
The History of Conservation in Shirakami Sanchi
The forests of Shirakami Sanchi were once used as sources of firewood, charcoal, and other natural resources. However, large-scale logging plans in the 1970s led to growing opposition and increased awareness of the importance of protecting the ancient beech forest.
Local residents, citizens, and environmental groups called for the preservation of the forest. These efforts eventually contributed to the area’s designation as a UNESCO World Natural Heritage Site in 1993.
Since then, the forests have been managed under strict conservation policies designed to preserve their natural character for future generations.
Protecting the World Heritage Forest
Government agencies, including Japan’s Ministry of the Environment and Forestry Agency, continue to monitor the World Heritage area and work to prevent illegal logging and damage to trees.
New conservation challenges continue to emerge. The increasing presence of Japanese deer, for example, may affect vegetation and the wider balance of the ecosystem. Ongoing scientific research and monitoring are therefore essential for understanding how the forest is changing.
