Wasabi Grown in the Pure Waters of the Northern Alps
Wasabi requires exceptionally clean, cool water, and Azumino provides an ideal natural environment. The spring water used at Daio Wasabi Farm remains cool even during the warmest months, allowing wasabi to grow under stable conditions.
Several varieties are cultivated at the farm, including Nagano No. 23, Mazuma, and Masamidori. Each variety has its own distinctive balance of fragrance, flavor, and pungency.
For visitors from overseas, seeing the wasabi fields themselves is an opportunity to discover an aspect of Japanese cuisine that is rarely visible in restaurants. Rather than being grown in ordinary soil, wasabi here is cultivated in flowing, crystal-clear water, creating a distinctive landscape of green plants and sparkling streams.
Beautiful Wasabi Fields and Scenic Walking Paths
The extensive farm is arranged around broad wasabi fields, where clear water glitters in the sunlight as it flows between rows of green plants. During summer, black shading cloth is placed above many of the fields to protect the plants from strong sunlight. The contrast between the dark coverings, vivid greenery, and transparent water creates one of the farm’s most recognizable scenes.
Visitors can explore the grounds along several walking paths shaded by trees. The Ryofū-no-Komichi, or Cool Breeze Path, and Poplar Path provide relaxing routes through the farm, while other paths lead to viewpoints, water features, shrines, and historic sites.
The scenery changes throughout the year, making a walk around the farm enjoyable in every season. The combination of flowing water, green fields, trees, and views toward the mountains creates a peaceful atmosphere despite the farm’s popularity.
The Watermill from Akira Kurosawa’s Dreams
A Famous Film Location in Azumino
One of Daio Wasabi Farm’s most iconic sights is a traditional watermill beside the Tadegawa River. The picturesque scene was used as a filming location for Akira Kurosawa’s 1990 film Dreams.
The watermill continues to turn slowly beside the clear stream, creating a tranquil image of rural Japan. Its traditional appearance, flowing water, and surrounding greenery make it one of the most memorable places to photograph at the farm.
Inside the building, panels and materials related to the filming are displayed, allowing visitors to learn more about the connection between Kurosawa’s film and the landscapes of Azumino.
A Tourist Farm Where You Can Taste Wasabi
Daio Wasabi Farm is as much a place for tasting as it is for sightseeing. Visitors can discover the distinctive flavor of wasabi through a variety of creative local foods.
Popular Wasabi Specialties
Wasabi soft-serve ice cream is one of the farm’s best-known treats. Its cool sweetness is combined with the refreshing aroma and subtle heat of wasabi, creating an unusual but surprisingly enjoyable flavor.
Wasabi croquettes are another popular snack, offering a savory taste with a distinctive wasabi kick. Restaurants and soba establishments on the grounds also serve dishes using freshly grated wasabi, including soba and rice bowls.
For travelers interested in Japanese food culture, tasting freshly grated wasabi in the place where it is grown provides a very different experience from eating processed wasabi commonly served with sushi overseas.
Wasabi Products to Take Home
The farm’s shops offer a wide selection of wasabi products that make distinctive souvenirs. Popular choices include wasabi-zuke, wasabi-flavored rice crackers, wasabi dressing, and other processed products made from local wasabi.
These products offer an easy way to take home a taste of Azumino and discover the many ways wasabi is incorporated into Japanese cuisine beyond sushi and sashimi.
The History of Daio Wasabi Farm
A Twenty-Year Effort to Create the Farm
The history of Daio Wasabi Farm began in 1915, during the Taisho period. The farm’s founder recognized the abundant spring water flowing through the Azumino alluvial fan and envisioned transforming what was then largely undeveloped land into a productive wasabi-growing area.
Negotiations with landowners across five villages took two years. Development finally began in 1917, and the work continued through years of painstaking effort. In 1926, the first major section, known as Daio Batake, was completed. The overall development project continued for approximately 20 years, reaching completion around 1935.
From Agricultural Land to a Major Tourist Attraction
After World War II, the organization was restructured as a limited company. In 1961, the Higashibatake section was completed, expanding the cultivated area.
A shop was constructed in 1976, and in the summer of the same year, the Crown Prince and Princess of Japan, now the Emperor Emeritus and Empress Emerita, visited the farm. A restaurant building was completed in 1982, further developing the farm as a destination for visitors.
In 1985, the Azumino Wasabi Field Spring Water Group, which includes the spring waters of the farm, was selected as one of Japan’s 100 Remarkable Waters by the former Environment Agency. This recognition helped make Azumino’s exceptional water resources known throughout Japan.
A new company office and factory were completed in 1997, and in 2021, the organization adopted a new corporate structure as a joint-stock company, continuing the farm’s long agricultural and tourism tradition.
Places to Explore within the Farm
Four Main Wasabi Field Areas
The farm’s cultivated landscape is divided into four principal areas: Daio Batake, Higashibatake, Kitabatake, and Furubatake. Together, they form the extensive network of wasabi fields that gives the farm its distinctive character.
Shrines and Legendary Sites
Among the attractions within the grounds are Daio Shrine, Daio Cave, Kaiun Cave, and the Daio-sama Watchtower. These sites add a cultural and historical dimension to a visit beyond the agricultural scenery.
Mountain Views and Water Experiences
The Alps Viewpoint provides an opportunity to appreciate the surrounding mountain landscape, while the Water Plaza brings visitors closer to the clear spring water that sustains the wasabi fields. A drinking-water station associated with Japan’s 100 Remarkable Waters allows visitors to experience the spring water directly.
Paths, Bridges, and Relaxing Spaces
Walking routes such as the Cool Breeze Path and Poplar Path wind through the grounds. The Saiwai-no-Kakehashi Bridge and other scenic spots provide pleasant places to pause and enjoy the natural surroundings.
Several dining and rest facilities, including Iwána Chaya, a soba restaurant, a main restaurant, and a tea house, make it easy to spend several hours exploring the farm.
Event and gathering spaces such as Yume Hall, Daio Plaza, and Aozora Plaza are also used for various activities, adding to the farm’s role as a destination for both local residents and visitors.
Daio Shrine and the Legend of Hachimen Daio
The name Daio comes from Daio Shrine located within the farm. According to local folklore, the shrine is associated with Hachimen Daio, a legendary figure appearing in traditional stories from the Azumino region. It is said that the body of Hachimen Daio was buried at this site.
Daio Shrine has been revered as a local guardian shrine, and its presence gave the farm its distinctive name. The combination of agricultural landscape, shrine traditions, and local legends adds another layer of character to the site.
The Azumino Wasabi Field Spring Water Group
Daio Wasabi Farm is part of the Azumino Wasabi Field Spring Water Group, an exceptionally abundant groundwater system recognized among Japan’s 100 Remarkable Waters.
The area lies at the lower end of a complex alluvial fan formed by the Saigawa, Hotaka River, and Takase River, whose waters originate in the Jonen Mountain Range. Snowmelt and rainwater filter through the mountain landscape and underground gravel layers before emerging as exceptionally clear, cool spring water in Azumino.
The total amount of groundwater emerging in this region is estimated at approximately 700,000 tons per day. This abundant water supports not only wasabi cultivation but also other local agricultural and aquatic products, including rainbow trout.
In 1995, Azumino was also selected as one of Japan’s 100 Water Villages under the theme of a region filled with water and local legends. The relationship between water, agriculture, scenery, and local culture is one of the defining characteristics of Azumino.
