Aoni Village is a historic mountain settlement in the northeastern part of Hakuba Village, Nagano Prefecture. Located at an elevation of approximately 760 meters on a mountainside, the village preserves a traditional rural landscape that has developed in harmony with the surrounding mountains and forests.
Aoni is part of the Kita-Shiro district of Hakuba Village and has been designated as an Important Preservation District for Groups of Traditional Buildings by the Japanese government. Looking southwest from the village, visitors can enjoy sweeping views across the Hakuba area toward the magnificent peaks of the Northern Alps.
Aoni Village lies in a peaceful natural setting, with Iwato-yama to the north and Mount Monomi and Happo-yama to the east. Forests spread behind the settlement, while the mountains of the Northern Alps rise dramatically in front of it.
On clear days, the distinctive peaks of Mount Goryu and Mount Kashima-Yarigatake can be seen beyond the village. The scenery changes throughout the year, from fresh greenery and rice fields in spring and summer to colorful autumn foliage and snow-covered mountains in winter.
One of Aoni’s most distinctive features is the approximately 200 terraced rice fields spread across the eastern side of the settlement. Supported by traditional stone walls, these fields preserve the appearance of an old Japanese farming village and have been selected among the 100 Best Rice Terraces in Japan.
The terraces are sustained by the Aoni Irrigation Canal, a waterway approximately 3 kilometers long that was constructed during the Man’en and Bunkyū periods at the end of the Edo period, from 1860 to 1863. The canal continues to carry water today, demonstrating how generations of residents adapted to the steep mountain landscape and developed sustainable ways of cultivating rice.
The history of human activity around Aoni extends far beyond the traditional houses seen today. Archaeological sites including the Zenki-do Site and Baba Site have revealed traces dating from the middle to late Jomon period, showing that people lived in this mountainous area thousands of years ago.
Over the centuries, the community developed alongside its natural surroundings, creating a distinctive landscape in which farmland, houses, waterways, forests, and mountain slopes are closely connected.
Many of the buildings that define the present-day village were constructed from the late Edo period through the Meiji period. Large traditional main houses, originally characterized by thatched roofs, are particularly distinctive.
Many roofs were later covered with metal sheets for practical reasons, but the overall appearance of the buildings and their relationship to the surrounding landscape still preserve the atmosphere of an old mountain farming community.
Aoni retains 15 main houses, 14 of which preserve traditional architectural forms. Many are still used as private residences, making the village more than a historical exhibit. Visitors can experience a landscape where traditional architecture remains part of everyday life.
Seven traditional storehouses also remain. These were built separately from the main houses to reduce the risk of fire spreading, a practical feature that reflects the wisdom of traditional Japanese rural architecture.
The houses are arranged along the contours of the mountains across an area approximately 250 meters from east to west and 100 meters from north to south. Stone walls, irrigation channels, and carefully maintained vegetation naturally define the boundaries between properties.
Unlike many traditional settlements, Aoni has relatively few fences and hedges. This creates an open atmosphere and allows houses, rice terraces, waterways, and mountain scenery to form a continuous landscape.
On the northern slope of the settlement stands Aoni Shrine, an important center of local faith. A stone-paved approach and steps lead visitors toward the shrine, creating a quiet and solemn atmosphere among the surrounding trees.
Traditional festivals are held at the shrine in May, September, and November. The spring festival in May, main festival in September, and autumn festival in November remain important events for local residents and reflect the continuing spiritual traditions of the village.
Groups of historic stone Buddhist images can also be found near the entrance to the settlement, including the Mukaimasa Stone Buddhist Images and the Amida-do Stone Buddhist Images. These religious monuments offer a glimpse into the beliefs and everyday spiritual life of generations of villagers.
Aoni Village was selected as an Important Preservation District for Groups of Traditional Buildings on December 4, 2000. The designated area covers approximately 59.7 hectares, extending beyond the historic houses to include the rice terraces, irrigation canals, and surrounding woodland.
This broad designation recognizes the value of Aoni as a complete cultural landscape. Rather than preserving individual buildings in isolation, the village protects the relationship between architecture, agriculture, water systems, forests, and the natural environment.
Aoni is both a heritage destination and a place where people continue to live. This is one of the qualities that makes the village particularly special for visitors from overseas. The traditional houses and rice terraces are not simply preserved scenery; they remain part of a living rural community.
When exploring the village, visitors are encouraged to respect the privacy and daily lives of local residents. Walking quietly, staying on appropriate paths, and appreciating the landscape without disturbing the community help ensure that Aoni’s unique character can be preserved for future generations.
Aoni Village offers a rare glimpse of traditional rural Japan against the dramatic backdrop of the Northern Alps. Archaeological traces reaching back to the Jomon period, traditional houses from the Edo and Meiji periods, centuries-old irrigation systems, terraced rice fields, stone Buddhist images, and continuing shrine festivals all come together in one mountain settlement.
The changing seasons add another dimension to the experience. Green rice fields and alpine mountains dominate the warmer months, while autumn brings vivid colors to the surrounding slopes. In winter, snow transforms the traditional houses and terraces into a serene mountain landscape.
For travelers exploring Hakuba, Aoni offers a different perspective on the region—one that goes beyond mountain sports and spectacular alpine scenery. A walk through its historic lanes and terraced fields reveals the enduring connection between the people of Hakuba and the mountains that surround them.
