An Ancient Shrine Recorded in the Izumo Fudoki
Karakama Shrine has a history dating back more than a thousand years. It appears in the Izumo Fudoki, compiled in 733, under the name “Karakama Shrine,” and is also recorded in the Engishiki Jinmyocho, compiled in 927. These records indicate that the shrine was already regarded as an important sacred site in ancient times.
During the Edo period, the shrine was also known as Chio Gongen. Through the centuries, it has been protected and maintained by the local community.
The Meaning Behind the Name “Karakama”
Several theories exist concerning the origin of the name “Karakama.” One connects the name with ironworking and metalworking technologies introduced from the Korean Peninsula.
According to local traditions, Susanoo-no-Mikoto traveled to Silla on the Korean Peninsula and later brought knowledge of forestry, tatara ironmaking, and metalworking techniques to Japan. The word “kama” can refer to a furnace or cauldron, which may be connected with the shrine’s name.
The surrounding area was also associated with ancient mining. Deposits of copper and lead were once worked here, while traces of primitive tatara ironmaking and naturally occurring copper have also been identified. These remains suggest that the region had connections with metalworking and mining from ancient times.
A Mysterious Trail and the Famous Rock Passage
The most distinctive feature of Karakama Shrine is its challenging approach. From the parking area, visitors must walk approximately 800 meters through a cedar forest. After a quiet walk through the trees, a torii gate appears on the right, marking the beginning of the more demanding mountain trail.
From there, approximately 300 steep stone steps lead upward. The stones vary in size and can become extremely slippery, particularly after rain. In some sections, ropes are provided to help visitors climb safely.
Pass Through a Gap Only About 45 Centimeters Wide
At the top of the stone steps, visitors encounter the shrine’s most remarkable challenge: a narrow opening between enormous rocks.
The gap is only about 45 centimeters wide, narrow enough that adults generally need to turn their bodies sideways to pass through. This is known as the “rock passage”, and visitors must pass through it to reach the main sanctuary.
Beyond the opening, a small shrine building stands quietly among towering rock walls. The dramatic landscape can feel almost otherworldly, creating a powerful sense of mystery and seclusion.
What to Wear and Things to Keep in Mind
Karakama Shrine is not a highly developed tourist attraction. It stands in a natural mountain environment, so visitors should prepare carefully before making the journey.
The trail is unpaved, and the stone steps can become very slippery during or after rain. Comfortable walking shoes or hiking shoes are strongly recommended, along with clothing that allows you to move easily.
Mobile phone reception may also be limited in some areas. Visitors should allow plenty of time, avoid rushing, and take extra care if they are not accustomed to steep mountain trails.
The Legend of the Rock Boat and Susanoo
Near the torii gate stands a huge rock known as Iwafune, or the “Rock Boat.” According to legend, it is the transformed remains of the boat used by Susanoo-no-Mikoto when he returned from the Korean Peninsula.
The story reflects traditions connecting Karakama Shrine with ancient cultural exchange and maritime travel. The Izumo region is believed to have had connections with the Korean Peninsula since ancient times, and the shrine preserves part of this fascinating history through legend.
A Legend Connected with Wanibuchi-ji Temple
Another local tradition concerns Chishun Shonin, the legendary founder of Wanibuchi-ji Temple.
According to the story, three mysterious elderly men arrived by boat to meet Chishun Shonin and guided him to Wanibuchi-ji. The three men were said to be the manifestations of Chio Gongen of Karakama Shrine, Shirataki Gongen of Bessho, and Tabuse Gongen of Mount Tabuse.
After completing their task, the three figures are said to have divided the equipment from their boat, which subsequently transformed into rocks. The Iwafune at Karakama Shrine is traditionally considered one of these rocks, blending mythology, religious belief, and the natural landscape into a fascinating local tradition.
Local Faith and the Karakawa Kagura Tradition
Although the main sanctuary lies deep in the mountains, a worship hall was established in the Karakawa settlement so that local residents could visit and pray more easily.
Because the main sanctuary is located directly behind the worship hall, local tradition holds that visitors can receive the same spiritual blessings by praying at the worship hall.
Karakawa Kagura
During the annual autumn festival, Karakawa Kagura, designated an Intangible Folk Cultural Property by Izumo City, is performed every other year.
The ritual performance begins in the evening of November 2 and continues until the early hours of the following morning. The dramatic dances and powerful musical accompaniment echo through the mountain village, creating a deeply atmospheric experience.
Kagura has been an important part of religious life and community culture in the Izumo region for centuries, and the tradition continues to be carefully preserved by local residents.
Geology and Nature Around Karakama Shrine
The area around Karakama Shrine is characterized by extensive deposits of green tuff, a type of volcanic rock formed through submarine volcanic activity.
Copper, pyrite, and lead ores were once mined in the region, and mining played an important role in the local economy. Place names such as “Kanahori,” meaning “metal mining,” and surviving traces of primitive tatara ironmaking provide clues to the area’s long relationship with metal resources.
There is also a theory that the rocky chamber containing Karakama Shrine may have once been used for copper mining. The site is therefore particularly interesting because natural geology, human activity, and religious belief overlap in one place.
Karakawa Village and the New Tea Festival
Karakawa, where Karakama Shrine is located, is also known as one of Shimane Prefecture’s tea-producing areas.
At the local Ocha no Sato Karakawa-kan, a New Tea Festival is held in spring, while a Bancha Festival takes place in autumn. Visitors can purchase sencha and Karakawa bancha, watch demonstrations of traditional tea-mochi making, and enjoy local specialties such as Karakawa manju and tea-flavored rice.
Local agricultural products are also sold at the events, making them a pleasant opportunity to experience the warm atmosphere, food, and traditional culture of this rural mountain community.
Inome Cave
A Mysterious Sea Cave Said to Be an Entrance to the Land of the Dead
Inome Cave is a sea-eroded cave facing Inome Bay on the northern coast of the Shimane Peninsula. It is traditionally associated with the “Yomi no Ana,” or “Cave of Yomi,” mentioned in the ancient Izumo Fudoki.
In Japanese mythology, Yomi is the realm of the dead where Izanami-no-Mikoto is said to have lived. Ancient people may have regarded the cave as an entrance connecting the world of the living with the otherworldly realm of Yomi. Even today, the cave has a distinctive atmosphere of silence and mystery.
An Archaeological Site Revealing Ancient Life
Investigations were conducted inside the cave during harbor improvement work in 1948. Human remains, pottery, wooden objects, and other archaeological materials were discovered, revealing evidence of burial and daily life from the Jomon period through the Kofun period.
Among the discoveries were a male skeleton dating from the late Yayoi period, bracelets made from Gohoura shell from the South Seas, a wooden coffin, pottery, and iron objects.
A distinctive burial practice involving the use of a dugout canoe to cover the remains was also identified. These discoveries provide valuable evidence of ancient communities whose lives were closely connected with the sea.
A Cave Resembling a Wild Boar’s Eye
The name “Inome” is traditionally said to derive from the shape of a depression on the opposite side of the cave, which resembles the eye of a wild boar.
The cave measures approximately 30 meters wide and extends roughly 30 to 50 meters deep, creating an impressive natural setting. The surrounding area is also characterized by green tuff typical of the Sea of Japan coast and has been recognized as a geosite within the Shimane Peninsula–Lake Shinji–Lake Nakaumi Geopark.
Safety When Visiting the Cave
The floor inside the cave can be uneven, and small stones may fall from the ceiling. Visitors should exercise caution and wear shoes with good grip.
Some of the artifacts discovered at Inome Cave are displayed at the Izumo Yayoi-no-Mori Museum. Visiting the museum together with the cave can provide a deeper understanding of ancient Izumo and the people who lived in this region.
Wanibuchi-ji Temple
An Ancient Tendai Buddhist Temple Associated with the Legend of Benkei
Wanibuchi-ji Temple is a historic Tendai Buddhist temple in Bessho, Izumo City. It is traditionally said to have been founded in 594 by Chishun Shonin and has a history spanning more than 1,400 years.
The temple flourished as a sacred site associated with mountain asceticism. Surrounded by dense forests and mountains, the grounds have a peaceful and solemn atmosphere.
A Famous Autumn Foliage Destination
Wanibuchi-ji is also known as one of Shimane’s notable autumn foliage destinations. From late October through late November, the temple grounds are transformed by brilliant red and orange leaves.
The annual Autumn Foliage Festival is held during this period, allowing visitors to enjoy the temple’s historic atmosphere surrounded by colorful woodland.
Legends of Musashibo Benkei
Wanibuchi-ji is traditionally associated with Musashibo Benkei, the famous warrior monk of Japanese history and legend. According to local tradition, Benkei trained at the temple when he was young.
The temple also preserves a large temple bell said to have been carried by Benkei. The annual Musashibo Benkei Festival celebrates these historical and legendary connections with the local community.
A Unique Meeting Point of Myth, Nature, and Spiritual Tradition
Karakama Shrine is much more than a scenic tourist destination. Ancient beliefs, Izumo mythology, mountain asceticism, metalworking traditions, natural worship, and local community culture all come together here.
The journey itself is part of the experience. After walking through the quiet cedar forest, climbing steep stone steps, and carefully passing through the narrow opening between enormous rocks, visitors finally reach the small sanctuary hidden within the mountains.
The stillness of the forest, moss-covered stones, towering cliffs, and fresh mountain air create an atmosphere far removed from everyday life. Rather than simply sightseeing, a visit offers an opportunity to experience the relationship between nature and spirituality that has shaped the culture of Izumo for centuries.
For travelers seeking a different side of Izumo beyond the better-known shrines and attractions, Karakama Shrine offers a remarkable glimpse into the region’s deeper spiritual and cultural heritage.
