Sakaki Town is located in northern Nagano Prefecture, at the meeting point of the Hokushin and Toshin regions. Surrounded by mountains and crossed from north to south by the Chikuma River, the town combines beautiful natural scenery with a long history, distinctive local cuisine, agriculture, and a strong tradition of manufacturing.
Sakaki is part of Hanishina District and lies within the southern part of the Nagano area. At the same time, its lifestyle, economy, and climate share characteristics with the neighboring Toshin region. This location has helped create a unique local culture where different regional traditions meet.
The Chikuma River, the longest river in Nagano Prefecture and known downstream as the Shinano River, has played an important role in the lives and agriculture of Sakaki’s residents for centuries. The Hanishina Headworks, constructed between 1952 and 1968, has helped provide water for agriculture and support the region’s farming communities.
Several smaller rivers, including the Hinazawa, Mido, Tani, and Fukuzawa Rivers, also flow through the town. Together with the Chikuma River, they create a landscape of fertile farmland, waterways, and green countryside.
Mount Omine, Mount Kyodai, and Mount Goriga-mine rise around the town, offering opportunities for hiking, walking, and enjoying seasonal scenery. From the surrounding mountains and elevated areas, visitors can appreciate wide views of the Chikuma River valley and the changing colors of the Japanese countryside.
Sakaki has a typical inland basin climate, characterized by relatively low annual rainfall and many sunny days. The difference between daytime and nighttime temperatures can be significant, creating conditions that are particularly suitable for growing fruit.
Apples, grapes, and peaches are cultivated in the surrounding hills, while greenhouse farming produces roses, carnations, and lisianthus flowers. In recent years, efforts have also been made to develop Sakaki as a production area for wine grapes.
The combination of sunny weather, dry conditions, and fertile land gives Sakaki’s agricultural products their distinctive character and makes the countryside especially attractive during the flowering and harvest seasons.
One of Sakaki’s best-known agricultural products is Nezumi Daikon, a traditional Shinshu vegetable with a distinctive shape. Its lower portion becomes rounded while the root extends into a narrow point, giving it an appearance reminiscent of a mouse. This unusual shape is the origin of its name, which literally means “mouse daikon.”
Nezumi Daikon is known for its strong, sharp flavor. At the same time, its finish has a subtle sweetness that local people describe as “amamokkura.” The combination of intense spiciness and gentle sweetness is one of the characteristics that makes this radish special.
It is traditionally used for pickles and as a filling for oyaki, a regional Nagano specialty. It can also be grated with its skin on and used as a condiment for soba and udon noodles.
Nezumi Daikon grows particularly well at elevations of around 400 to 500 meters, where the soil contains small stones and the environment tends to be relatively dry. Farmers use relatively little fertilizer, and the radishes are harvested from around mid-November to mid-December.
Harvesting before the roots become too large helps preserve the characteristic sharp flavor. For visitors interested in Japanese food culture, Nezumi Daikon offers a fascinating example of how local climate, soil, and traditional farming practices can shape a regional food.
Oshibori Udon is one of Sakaki’s signature dishes. The soup is made using the freshly squeezed juice of grated Nezumi Daikon. The spicy radish juice is combined with Shinshu miso, then served with hot udon noodles and toppings such as green onions and dried bonito flakes.
The noodles are often served kamaage-style, meaning they are presented hot and freshly cooked. The sharp heat of the radish juice and the rich, savory flavor of miso create a distinctive combination that is especially satisfying during the cold winter months.
Oshibori Udon can be enjoyed at local restaurants as well as at roadside facilities and other places serving regional cuisine. Trying this dish is one of the best ways to experience Sakaki’s food culture.
Sakaki Chikuma River Rose Park is one of the town’s most colorful seasonal attractions. Located beside the Chikuma River, the park becomes especially beautiful in June, when more than 2,300 rose plants representing around 250 varieties come into bloom.
The combination of colorful roses, the flowing river, and the surrounding mountains creates an attractive landscape that draws visitors during the flowering season. The park is also a pleasant place to experience Sakaki’s connection with flower cultivation.
Iwahana is a striking natural landmark where enormous rocks rise dramatically from the surrounding landscape. Weathered over countless years, the rocks demonstrate the power of natural erosion and create an impressive scene in the Chikuma River area.
The contrast between the massive rock formations, green mountains, and river valley makes this an appealing destination for visitors who enjoy scenic landscapes and outdoor exploration.
Sakaki Iron Museum introduces visitors to the town’s long connection with metalworking and manufacturing. Exhibits explore traditional ironworking techniques as well as modern industrial products.
Manufacturing is a major part of Sakaki’s identity. The town has developed into one of Nagano Prefecture’s important industrial centers, with companies specializing particularly in machinery and metal processing. The roots of this industrial development can be traced back to factories relocated to the area during the early Showa period.
Today, companies with a wide range of specialized technologies form an important industrial cluster in the town. This combination of traditional craftsmanship and advanced manufacturing has given Sakaki a reputation as a town of manufacturing and technology.
Katsurao Castle Ruins are associated with the Murakami clan, one of the powerful samurai families active in Shinano during the Warring States period. The castle occupied a strategic position overlooking the surrounding area and offers visitors a glimpse into the turbulent history of medieval Japan.
For travelers interested in samurai history, walking through the castle ruins provides an opportunity to imagine the fortified mountain landscapes and political struggles that shaped Nagano during the Sengoku period.
Sakaki Shrine has been an important place of worship in the region since ancient times. It is associated with the ancient Engishiki shrine tradition and continues to be respected as a guardian shrine of the local community.
The peaceful grounds and long history make the shrine an interesting stop for visitors exploring Sakaki’s traditional culture and religious heritage.
Nakanojo Jinya is associated with the administrative system of the Edo period, when regional areas were governed through officials appointed by the shogunate. The site offers another connection to Sakaki’s history as an important settlement along the historic transportation routes of central Japan.
During the Edo period, Sakaki-juku developed along the Hokkokukaido Highway, an important route connecting inland areas of central Japan with the Sea of Japan. The post town served travelers, merchants, and the transportation of goods, making it an important center of movement and commerce.
A Sakaki Domain was established for a period, but the area later came under direct control of the Tokugawa shogunate. A Sakaki Jinya was established as an administrative center for the shogunate’s territory.
The town’s present name and written form, “Sakaki,” were officially changed in May 1886. The historic streets and surviving sites provide clues to the town’s development from a post town into the modern community seen today.
Sakaki is also known as a town of swordsmiths. During the Showa period, renowned swordsmith Miyairi Yukihira, who was recognized as a Living National Treasure, achieved outstanding results in the traditional art of Japanese sword making and trained numerous students.
His legacy helped establish a continuing tradition of Japanese sword craftsmanship in Sakaki. The town’s manufacturing culture therefore extends beyond modern machinery and metalworking, connecting contemporary industry with centuries-old Japanese techniques.
The Chikuma River also supports traditional fishing activities. Ayu fishing using tomozuri, a technique in which a live decoy fish is used to attract another ayu, is a traditional summer activity in river communities throughout Japan.
Experiencing or learning about ayu fishing offers visitors another way to appreciate the relationship between Sakaki and the Chikuma River, which has supported local agriculture, food culture, and daily life for generations.
Sakaki’s local specialties reflect both its agricultural heritage and its manufacturing culture. Nezumi Daikon products, pickles, and foods made with the distinctive radish make memorable regional gifts, while Shinshu miso produced by local makers is another representative taste of the area.
The town is also known for “Sakaki no Kagayaki,” an original rose developed in Sakaki. With its elegant flowers, the rose represents the town’s strong connection with flower cultivation and makes an appropriate symbol of this agricultural community.
Sakaki Town offers a different side of Nagano from the famous mountain resorts and historic cities. Here, the Chikuma River, fruit orchards, flower gardens, samurai history, traditional food, swordmaking, and modern manufacturing all form part of the town’s identity.
Visitors can enjoy roses beside the river in early summer, taste spicy Nezumi Daikon and Oshibori Udon, explore the ruins of a Sengoku-period castle, learn about traditional Japanese swordmaking, or simply walk through the countryside surrounded by mountains.
With its combination of natural beauty, agricultural traditions, historic sites, and distinctive manufacturing culture, Sakaki is a fascinating destination for travelers who want to discover a less-touristed side of Nagano and experience the everyday history and culture of a Japanese regional town.
