Akiyama-go (Nagano Prefecture) Complete Guide: Experiencing Four-Season Spectacular Scenery and Historical Culture in Japan’s Hidden Gem
What is Akiyama-go: A Peach Blossom Spring in the Mountains Selected as One of Japan’s 100 Hidden Gems
Akiyama-go (秋山郷) is a mountainous region along the Nakatsugawa River spanning Sakae Village in Shimominochi District, Nagano Prefecture, and Tsushma Town in Nakauonuma District, Niigata Prefecture. It is a collective name for 12-13 settlements scattered in a V-shaped valley flanked by Mount Nabeyama (2,145m) to the east and Mount Torikomai (2,037m) to the west, and is counted as one of Japan’s 100 hidden gems.
This region, called “Peach Blossom Spring” by the Edo Period literatus Shigeru Suzuki in his “Akiyama Journey,” remains a special place where the traditional lifestyle and unique culture of old Japan are distinctly preserved. There are five settlements on the Nagano side and eight on the Niigata side, each inheriting its own unique history and culture.
Geographic Characteristics of Akiyama-go
Formed along the clear stream of the Nakatsugawa River, Akiyama-go is characterized by its dramatic gorge scenery. National Route 405 is the only main road connecting the settlements, and the continuous winding road gives visitors a sense of being in a hidden gem. The terrain with elevation differences nurtures diverse vegetation and fauna, revealing the four seasons’ changing faces in a treasure trove of nature.
In winter, heavy snowfall of 3-4 meters accumulates, and this harsh natural environment has nurtured a unique culture and way of life. During winter months when deep snow shuts off the region, contact with the outside world was historically extremely limited, to the point of being described as “forgotten by history.”
History of Akiyama-go: Heike Clan Fugitive Legends and Formation of Unique Culture
Heike Clan Fugitive Legends and Origins of Settlements
Akiyama-go has numerous legends about Heike clan fugitives. The tradition that samurai of the Heike clan, defeated at the Battle of Dannoura, fled here to these steep mountains to escape pursuers has become an important element of the region’s identity.
Various theories exist regarding when settlements formed, but their appearance in written records dates from the Sengoku period onward. During the Edo period, as a border region between Echigo and Shinano provinces, the area experienced complex overlapping administration of both domains. After the Meiji Restoration’s abolition of the han system, the prefectural border between Nagano and Niigata became divided among settlements, a situation that continues today.
Shigeru Suzuki and “Akiyama Journey”
During the late Edo period, literatus Shigeru Suzuki visited Akiyama-go in 1828 (Bunsei 11) and documented his experience in “Akiyama Journey” (Akiyama Kiko). By describing Akiyama-go as “Peach Blossom Spring” in this travel journal, the image of Akiyama-go as a hidden gem became widely known.
Suzuki documented in detail the simple lives of Akiyama-go’s people, their unique customs, and the wisdom cultivated in their harsh natural environment. This record remains an important resource for Akiyama-go research today and continues to hold value as precious testimony to regional culture.
Settlements of Akiyama-go: Characteristics of Five Nagano Prefecture Settlements
The five main settlements of Akiyama-go on the Nagano side of Sakae Village are as follows.
Koakasawa (小赤沢)
One of Akiyama-go’s central settlements and home to the Sakae Village Akiyama-go Tourism Association. Traditional homes remain, and several inns offer opportunities to experience Akiyama-go culture. In spring, Oyamayama cherry blossoms bloom surrounding the settlement, and the spring scenery with Mount Nabeyama in the background is known as spectacular.
Yashiki (屋敷)
This settlement is characterized by Nunoiwa, a giant single rock face. The approximately 100-meter-high rock wall exerts an overwhelming presence and is one of Akiyama-go’s representative landscapes. A hot spring facility sits at the base of Nunoiwa, making it a popular tourism hub.
Uenohara (上野原)
Located at the deepest point of Akiyama-go, this settlement was once called “Japan’s Last Hidden Gem.” While depopulation is progressing, beautiful terraced fields remain, and the original Japanese landscape continues to captivate visitors.
Wayama (和山)
Positioned along the Nakatsugawa gorge stream, this settlement is popular as a base for fishing and camping. Hiking trails are developed in the surrounding area, allowing close experience of gorge scenery.
Kiriaké (切明)
Located at the deepest part of Akiyama-go, this settlement serves as an entrance to the Shiga Highlands. Kiriaké Hot Spring is known as “River-in-the-Open Bath” where hot spring water flows from the riverbed, allowing the unique experience of stacking stones to create your own bathing pool. It is an important base for hiking and trekking.
Akiyama-go’s Unique Culture and Lifestyle
Slash-and-Burn Farming Tradition
Slash-and-burn agriculture was once widely practiced in Akiyama-go. This farming method using steep mountain slopes was adapted to the region’s harsh natural environment. Traditional agricultural techniques involved cutting and burning mountain trees, using their ash as fertilizer to grow buckwheat, millet, and other grains.
While the number of farmers practicing this has decreased, some settlements continue slash-and-burn farming as cultural heritage preservation. Buckwheat grown through slash-and-burn has rich flavor and is treasured as an Akiyama-go specialty.
Matagi Culture and Hunting Traditions
Akiyama-go also has deep-rooted matagi (hunter) culture. With abundant forest resources and wildlife, hunting was one of the important livelihoods. Hunting techniques for bears, deer, and wild boars have been passed down through generations, with unique hunting terminology and rituals also preserved.
Hunting continues today, and some inns serve gibier dishes featuring bear and venison. Matagi wisdom has become a regional source of pride as a symbol of coexisting with nature.
Mountain Snowy Region Knowledge: Thatch Roofs and Gangi
In this heavy snowfall region, unique architectural styles adapted to snow developed. Steep-pitched thatch roofs are designed to let snow naturally slide off, and examples can still be seen in some homes.
Additionally, gangi (雁木)—covered passages with eaves built to enable movement in deep winter snow—snow removal tools, and food storage using snow chambers exemplify the knowledge of snowy region living that still thrives today.
Traditional Crafts and Folk Performing Arts
Straw work and woodcraft traditions are preserved in Akiyama-go. In particular, straw crafts made during long snowy winters are intricate and beautiful, holding value not only as practical items but also as folk art.
As folk performing arts, kagura (sacred music and dance) and lion dances praying for abundant harvests and safety have been transmitted, with various rituals held throughout the year. These events also serve the important role of maintaining settlement communities.
Four-Season Spectacular Views: Highlights of Akiyama-go
Spring: Oyamayama Cherry Blossoms and Katakuri Flowers
Spring in Akiyama-go arrives with snowmelt. From late April through early May, Oyamayama cherry blossoms (Prunus jamasakura) color the settlements. These blossoms, in deeper pink than Somei-Yoshino varieties, bloom against the backdrop of snow-capped Mount Nabeyama, creating the true landscape of Peach Blossom Spring.
The cherry tree rows in Koakasawa settlement and the cherries against Nunoiwa in Yashiki settlement are particularly beautiful, attracting many photography enthusiasts. Forest floors also display katakuri flower colonies, with delicate purple flowers heralding spring’s arrival.

Autumn: Japan’s Finest Autumn Foliage
Akiyama-go’s autumn foliage is known as Japan’s most beautiful. From early October through early November, beech, maple, and rowan trees turn red and yellow, transforming the entire gorge into a brocade-like landscape.
Driving the Nakatsugawa gorge in particular offers continuous spectacular views, with the changing foliage scenery stealing one’s breath around each curve. The combination of Nunoiwa and foliage, autumn leaves reflected in Tenchi Pond’s surface, and foliage around Oaze Falls provide abundant photo opportunities.
