A Historic Mountain Region on the Ancient Tosando Road
Long before Hanamomo Village became known for its spring flowers, this area was an important part of the ancient Tosando road, one of the major routes connecting central Japan with the eastern provinces.
The area lies at the Shinano-side foot of Misaka Pass, which was considered the most difficult section of the ancient route. Nearby Sonohara and Shinano Hiei are also closely associated with the history of the Tosando and with the classical literature and poetry of Japan.
For centuries, travelers crossed these mountains on foot, while poets celebrated the surrounding landscapes in waka poetry. As the ancient road gradually declined in importance, the once-busy mountain settlement became a quiet and secluded rural community.
The Enasan Tunnel and the Renewal of the Valley
A major change came with the construction plans for the Chuo Expressway, which began in 1966. The project included the construction of the Enasan Tunnel through the mountains.
Local residents agreed to accept the excavated earth and rock produced during the tunnel construction. Rather than simply disposing of the material, they used it to restore agricultural land along the valley, creating new opportunities for the local community.
The Enasan Tunnel was completed in 1974, and the following year it opened to traffic. The new highway greatly improved access to the region and created the conditions for the area’s later development as a tourist destination.
How Hanamomo Village Was Created
The modern story of Hanamomo Village began in 1991, when the accommodation facility Noguma-no-Sho Tsukikawa opened as part of a local revitalization project.
Hanamomo trees had been introduced to the area from neighboring Okuwa Village. Inspired by the beauty of the trees, the facility’s then-president, Shuitsu Shibuya, arranged for approximately 1,000 trees to be planted around the inn.
The project soon developed into a community-wide effort. Local residents established the Hanamomo Village Development Committee and planted another 2,500 trees over a three-year period. Together, these efforts created a spectacular landscape of approximately 3,500 flowering trees.
Planting and maintenance continued, and by 2016, around 5,000 hanamomo trees had spread along the Hontanigawa River. The area had grown into a major spring attraction, welcoming approximately 200,000 visitors during the flowering season.
A Community Effort Throughout the Year
The beauty of Hanamomo Village is the result of continuous work by local residents. After the blossoms finish in late May, the trees are carefully pruned. From summer through autumn, the grass beneath the trees is cut and maintained, while fertilizer is applied during winter.
This year-round care ensures that the trees remain healthy and that the valley can continue to produce its spectacular spring display. The landscape visitors see during the flowering season is therefore not simply a natural phenomenon, but also the result of many years of community effort.
The Beauty of Hanamomo Blossoms
Hanamomo, or ornamental peach, is a variety of peach cultivated primarily for its flowers rather than its fruit. The blossoms range from single to double flowers, creating a diverse and colorful display.
Visitors can see flowers in vivid red, white, pink, and red-and-white combinations. Each blossom is relatively small, measuring approximately 3 to 5 centimeters across, but the sheer number of flowers covering the trees creates a dramatic effect.
The trees do produce fruit, but it is not suitable for eating. Their value lies in the extraordinary beauty of their blossoms, which make the entire valley appear to be painted in spring colors.
Best Time to Visit
The main flowering season is generally from mid-April to early May. The exact timing varies from year to year depending on weather and temperatures, so the peak period may shift slightly.
When the trees reach full bloom, the entire area surrounding the valley becomes a vibrant landscape of pink, white, and red. The combination of flowering trees, mountain scenery, and the quiet rural setting makes this one of Achi Village’s most memorable spring destinations.
Hanamomo Festival
The Hanamomo Festival is held during the flowering season. The event brings together local products, food, and other attractions, while visitors gather to enjoy the blossoms and take photographs of the colorful scenery.
For travelers visiting Achi Village in spring, the festival provides an opportunity not only to admire the flowers but also to experience the local community and regional culture.
A Spring Landscape Surrounded by Mountains
Hanamomo Village and Tsukikawa Onsen is particularly beautiful because the flowering trees are set against the mountains of southern Nagano. The contrast between the delicate blossoms and the surrounding rugged mountain landscape creates a distinctly Japanese spring scene.
The area is also close to several historic and natural attractions, making it easy to combine a visit to the flower valley with other sightseeing experiences.
Nearby Attractions
Nearby highlights include Sonohara, a historic landscape associated with ancient Japanese poetry; Shinano Hiei Kojo-in, a temple with a long connection to travelers on the ancient Tosando; Achi Village, known for its exceptionally clear night skies; Hirugami Onsen, a famous hot spring resort; Achi Shrine; Misaka Pass; and Fujimidai Highlands.
These attractions allow visitors to experience the area’s history, religious traditions, hot springs, mountain scenery, and famous star-filled skies as well as its spectacular spring flowers.
Access
From the Tokyo direction, Hanamomo Village is approximately 25 minutes by car from the Iida-Yamamoto Interchange on the Chuo Expressway. From the Nagoya direction, it is approximately 5 minutes by car from the Sonohara Interchange.
For visitors arriving by train, the area is approximately 40 minutes by car from JR Iida Station.
Traffic can become heavy during the peak flowering season, when large numbers of visitors arrive to see the blossoms. Allowing extra travel time is recommended, particularly on weekends and holidays.
Experience the Story Behind the Flowers
Hanamomo Village and Tsukikawa Onsen is more than a beautiful place to see spring flowers. Its landscape reflects a long history, from the ancient Tosando road and the travelers who crossed Misaka Pass to the modern community effort that transformed a quiet mountain valley into a celebrated flower destination.
With approximately 5,000 hanamomo trees lining the valley, the area becomes one of Achi Village’s most spectacular sights from mid-April to early May. A visit here offers travelers a chance to enjoy not only the beauty of Japanese spring, but also the story of a rural community that worked together to create and preserve this remarkable landscape.
