Unnan City is a nature-rich city in eastern Shimane Prefecture. It was established in 2004 and is relatively young as a municipality, but the area has a long history and a strong connection to the myths and traditions of the Izumo region.
Located south of the central Izumo area, Unnan combines beautiful mountains and rivers with ancient shrines, archaeological sites, traditional culture, and historic industrial heritage. It is an appealing destination for travelers who want to experience a quieter side of Japan while discovering the stories and landscapes of ancient Izumo.
One of Unnan’s distinctive features is its varied terrain. The southern part of the city extends into the Chugoku Mountains, where mountains reaching around 1,000 meters create a rugged landscape. In contrast, the northern part gradually opens toward the broad Izumo Plain.
This difference in elevation creates a variety of scenery and local climates. The Hii River and its tributaries, including the Aka River, Mitoya River, and Kuno River, have long supported the lives, agriculture, and culture of local communities.
The Hii River is particularly beautiful throughout the seasons. In spring, approximately 2 kilometers of cherry trees along its banks burst into bloom. The area is recognized as one of the 100 Best Cherry Blossom Viewing Sites in Japan.
Unnan’s climate varies between the northern and southern parts of the city. The northern area is relatively mild, with an annual average temperature of around 14°C, while the southern mountain area is cooler, at approximately 12–13°C.
Winter can bring considerable snowfall, particularly in the mountainous areas, creating beautiful snowy landscapes. Spring brings cherry blossoms, summer is filled with fresh green foliage, autumn offers colorful leaves, and winter transforms the mountains into a quiet world of snow.
These seasonal changes make Unnan an attractive destination throughout the year.
Suga Shrine is one of the most important shrines associated with the mythology of Izumo. It is also known as “Japan’s First Shrine” or “Nihon Hatsunomiya.”
According to legend, after the deity Susanoo-no-Mikoto defeated the eight-headed serpent Yamata-no-Orochi, he built a palace in this area. The peaceful atmosphere of the shrine provides visitors with an opportunity to experience the world of ancient Japanese mythology.
Unnan is closely associated with the story of Yamata-no-Orochi, the legendary eight-headed and eight-tailed serpent described in the Kojiki, one of Japan’s oldest historical texts.
Many locations connected with the legend can be found along the Hii River. Happonsugi, Yamata-no-Orochi Park, and Ama-ga-fuchi are among the places associated with the story.
Exploring these locations allows travelers to follow the footsteps of the ancient legends and gain a deeper understanding of the mythology that forms an important part of Japanese culture.
Ryuzuga-Yae Waterfalls are a spectacular group of waterfalls recognized among Japan’s 100 Best Waterfalls. The area consists of Ryuzuga Falls and Yae Falls, surrounded by a beautiful mountain landscape.
Yae Falls is particularly impressive, with eight waterfalls spread along approximately 1.5 kilometers of a mountain stream. Each waterfall has its own distinctive character.
Ryuzuga Falls consists of a male waterfall and a female waterfall. Its powerful flow creates an image reminiscent of a dragon rising toward the sky. The scenery changes dramatically with the seasons, making the area a rewarding destination for nature lovers and hikers.
Yoshida Town developed as one of the major centers of tatara ironmaking, a traditional Japanese method of producing iron using charcoal and iron sand.
The town grew under the influence of the Tabe family, who were powerful iron-producing entrepreneurs in the region. The historic townscape still preserves the atmosphere of the community that developed around the iron industry.
The town was carefully organized according to the surrounding terrain. The main street, temple district, Kawaramachi commercial area, and areas where blacksmiths worked each served different functions. Small lanes connect these districts, creating a distinctive historic townscape.
The Iron History Museum introduces visitors to the technology and history of tatara ironmaking. Its exhibitions are divided into two main themes: the technology of iron production and the people and management systems that supported the industry.
Visitors can learn about the important role of the murage, the highly skilled master responsible for controlling the ironmaking process, as well as the demanding work involved in operating a tatara furnace for several days.
The museum offers a valuable insight into one of Japan’s traditional manufacturing industries and the people who preserved its specialized techniques.
Sugaya Tatara Settlement is a rare surviving site where tatara ironmaking facilities and workers’ living quarters existed together. The site is designated as an Important Tangible Folk Cultural Property of Japan.
Its most important structure is the Sugaya Takadono, a traditional tatara furnace building and the only surviving example of its architectural type in Japan.
People involved in iron production once lived together deep in the mountains, forming a close community while preserving their specialized knowledge. Today, the settlement provides a fascinating glimpse into the history of traditional Japanese manufacturing and rural life.
Unnan is home to historic hot spring areas including Ushio Onsen and Izumo Yumura Onsen. Surrounded by mountains and forests, these hot springs are ideal places to relax after sightseeing.
Combining a visit to a hot spring with walks through the surrounding countryside is an excellent way to enjoy the slower pace of rural Japan.
Obara Dam is a large dam on the upper reaches of the Hii River. Standing approximately 90 meters high, it creates the scenic artificial lake known as Sakura-Orochi Lake.
The lakeside scenery changes throughout the year. In spring, cherry blossoms surrounding the water create an especially beautiful contrast between pink flowers, blue water, and green mountains.
Ishiteru Garden is a spacious strolling-style Japanese garden featuring carefully arranged stones, waterfalls, ponds, and natural scenery.
The garden changes with the seasons and offers a peaceful environment where visitors can appreciate the harmony between traditional Japanese garden design and the surrounding landscape.
Unnan is also home to historic Buddhist temples such as Komyoji Temple and Mineji Temple. These temples preserve centuries of religious and cultural history, as well as traditional architecture and gardens.
Mineji is particularly associated with the tradition of Shugendo, a Japanese mountain ascetic tradition, making it an interesting destination for travelers fascinated by Japan’s religious history.
The Hii River Embankment Cherry Blossom Row is one of Unnan’s most famous seasonal attractions. Approximately 2 kilometers of cherry trees line the riverbank in the Kisuki area, creating a spectacular tunnel of blossoms in spring.
The site is recognized as one of the 100 Best Cherry Blossom Viewing Sites in Japan. When the trees bloom together, the riverbank becomes a beautiful spring landscape, with petals drifting onto the surface of the water.
Nearby, visitors can also see Negai Bridge, a distinctive submerged bridge. During periods of high water, the bridge can disappear beneath the river, creating a unique landscape that is especially popular with photographers.
Kamo-Iwakura Ruins is an important Yayoi-period archaeological site. A large number of bronze bells known as dotaku were discovered here, and these artifacts have been designated as National Treasures of Japan.
The discovery provides important clues about religious rituals and social organization during the Yayoi Period. Exhibition facilities in the surrounding area allow visitors to learn about the artifacts and archaeological discoveries in an accessible way.
Mitoya Castle was once the residence of a regional warrior lord. Today, the former castle site is preserved as a prefectural historic site.
The ruins make use of the natural shape of the mountain, reflecting the defensive characteristics of a Japanese mountain castle. Visitors can enjoy a walk through the historic site while taking in views of the surrounding landscape.
The area is also attractive during cherry blossom season, when the historic ruins and spring flowers create a memorable combination.

Izumo Yumura Onsen has been enjoyed as a traditional therapeutic hot spring destination for centuries. Located along the Hii River, the hot spring area has a peaceful atmosphere surrounded by mountains and nature.
Soaking in the warm water while listening to the sound of the river is a relaxing experience. Walking routes around the area also allow visitors to combine a hot spring visit with an exploration of the surrounding countryside.
