Sagiura Port is a historic harbor on the Sea of Japan coast in Izumo City, Shimane Prefecture. Known since ancient times as a place where ships could wait for favorable winds, the port flourished as a stopover for Kitamaebune merchant ships. Located in a quiet inlet north of Izumo Taisha Grand Shrine, Sagiura is a fascinating destination where rich nature, historic townscapes, and Japanese mythology come together.
The harbor lies at the innermost part of a long, deep inlet surrounded by hills. This natural geography protects it from strong seasonal winds and high waves from the open sea. Kashiwajima Island, located at the entrance of the harbor, also serves as a natural breakwater, making Sagiura a safe refuge for ships throughout its long history.
Today, visitors can still see former sailors’ inns, merchant houses, and traditional homes with Sekishu roof tiles. The peaceful fishing-village atmosphere preserves traces of the port’s prosperous maritime past.
The defining feature of Sagiura Port is the natural harbor created by its unique geology. Approximately 16 million years ago, volcanic activity formed rhyolite and hydroclastic rocks along this part of the coast. Over time, these geological formations created the complex coastline and sheltered inlet seen today.
While the open Sea of Japan is known for its powerful waves, the waters inside Sagiura Port are remarkably calm. This made the harbor an important anchorage from ancient times. From the Edo period through the Meiji period, Sagiura became an essential port of call for Kitamaebune, the merchant ships that traveled the Sea of Japan.
Kitamaebune were large commercial vessels that sailed north from Osaka and Kyoto along the Sea of Japan coast to the Tohoku region and Hokkaido. They transported regional products such as rice, salt, kelp, and herring, supporting economic development in coastal communities throughout Japan.
At Sagiura Port, sailors would remain in the harbor until the winds became favorable. During their stay, they could unload and load cargo, replenish supplies, and rest. Inns, trading houses, and other businesses developed around the harbor, and Sagiura became a prosperous port town.
The village of Sagiura still retains strong traces of its Kitamaebune-era history. Narrow lanes are lined with traditional merchant houses and former sailors’ inns, and some buildings still display their historic yagō, or traditional family and business names.
One of the most distinctive features is the town’s rows of reddish-brown Sekishu roof tiles. Sekishu tiles are traditionally produced in western Shimane and are highly resistant to cold weather and salt damage, making them particularly suitable for coastal areas along the Sea of Japan.
Kitamaebune ships transported Sekishu tiles to various ports, and the tiles played an important role in shaping the traditional appearance of many coastal communities. In Sagiura, their warm red color creates a striking contrast with the blue waters of the Sea of Japan.
Views from the hills and elevated areas around the town reveal rows of red-tiled roofs stretching toward the harbor. The combination of traditional architecture, blue sea, and surrounding green hills makes Sagiura an appealing place for photography.
On the rocky western side of the harbor, visitors can also find old mooring holes and grooves carved into the rocks. These traces were used to secure ships and provide tangible evidence that Sagiura Port was once a busy center of maritime activity.
Sagiura prospered not only through maritime trade but also through copper mining. Copper had been extracted in the surrounding area for many years, and full-scale mining began in 1865 under orders from the Matsue Domain at the end of the Edo period.
Mining expanded during the Meiji period and became an important part of the regional economy. In 1900, annual copper production is said to have reached approximately 803 tons.
However, as railway networks developed from the Taisho period into the early Showa period, the importance of maritime transportation declined. The copper mines also eventually closed.
As the commercial role of the port diminished, Sagiura gradually became quieter. This change has helped preserve the town’s traditional atmosphere, allowing visitors today to experience a peaceful coastal settlement that still retains many traces of its past.
An essential part of Sagiura’s history is Inasehagi Shrine. The shrine is a branch shrine of Izumo Taisha and is closely connected with the mythology of the Izumo region.
The principal deity is Inasehagi-no-Mikoto, a deity who played an important role in the ancient Japanese story known as the Kuniyuzuri, or Transfer of the Land.
According to the Nihon Shoki, when Takemikazuchi and other envoys of Amaterasu Omikami asked Okuninushi-no-Mikoto to surrender control of the land, Okuninushi’s son Kotoshironushi-no-Kami was fishing at Mihonoseki.
Inasehagi-no-Mikoto was sent as a messenger and traveled aboard the Kumano Morotebune to deliver the message to Kotoshironushi-no-Kami.
In the mythology, the transfer was ultimately settled through discussion rather than armed conflict. Inasehagi-no-Mikoto has therefore been revered as a deity associated with the peaceful resolution of this important mythological event.
The main sanctuary of Inasehagi Shrine uses the Taisha-zukuri architectural style, one of Japan’s oldest shrine-building traditions and a style strongly associated with Izumo Taisha. Records also indicate that timber used during a reconstruction of Izumo Taisha was later reused here, reflecting the close historical relationship between the two shrines.
Today, fishing remains an important local industry in Sagiura. Fishing boats line the harbor, and the surrounding waters provide a variety of seafood, including yellowtail, grunt, Spanish mackerel, squid, and flounder.
The simple and welcoming atmosphere of a traditional fishing village is one of Sagiura’s attractions. In the early morning, the harbor becomes lively as local fishermen prepare for the day’s work, offering visitors a glimpse into everyday life closely connected with the sea.
Every year on July 31, the Gongen Festival is held to pray for abundant catches and safety at sea. Fishing boats decorated with large catch flags circle Kashiwajima Island.
The sight of the boats illuminated by the setting sun is one of the most memorable scenes of summer in Sagiura and reflects the community’s long-standing relationship with the ocean.
Sagiura’s appeal extends well beyond its history. The surrounding coastline forms part of Daisen-Oki National Park, offering spectacular views of the Sea of Japan and its rugged natural landscape.
One of the best ways to experience the area is the Sagiura Walking Trail, a route of approximately 2.5 kilometers that follows the coast and surrounding hills. Along the way, visitors can enjoy panoramic views of Sagiura Port and the open sea.
The trail passes through areas of Japanese cedar forest and features plants such as bayberry, chestnut, and Japanese camellia. The landscape changes throughout the year, making the walk enjoyable in different seasons.
Wild animals such as deer and wild boar may also be encountered in the surrounding natural environment.
Near the end of the trail, the area around Sagiura Lighthouse opens onto dramatic views of the intricately shaped coastline. Sheer cliffs, sea caves, and small islands combine to create an impressive panorama of the Sea of Japan.
The coastline around Sagiura is dotted with sea caves and unusual rock formations carved by waves over countless years. Many of these sites cannot be reached by land and are best experienced by boat.
One of the most famous is Mikazuki Bay Cave. A crescent-shaped opening in the ceiling of the cave allows sunlight to shine into the cavern. On clear days, the light can illuminate the seawater in a beautiful emerald-green color.
This otherworldly landscape, created entirely by natural forces, offers one of the most memorable sightseeing experiences around Sagiura.
Sagiura has preserved traditional customs that have been passed down through generations.
One example is Shagiri, a folk ritual held around the New Year. A man wearing an ogre mask performs an energetic dance while rubbing branches of sacred sakaki together, visiting homes throughout the community to drive away misfortune.
These rituals reflect the distinctive beliefs and festival culture of a traditional fishing community. They also offer visitors a glimpse into customs that have long been woven into everyday life in coastal Japan.
Sagiura offers many ways to explore the area, including walking through the historic port town, visiting shrines, hiking, boat cruises, and fishing.
Visitors can relax in a café created by renovating a former sailors’ inn, feel the sea breeze while walking along the coast, or simply spend time taking in the peaceful atmosphere of the harbor.
The port is particularly beautiful around sunset. As the evening light reflects across the quiet inlet, the traditional town and surrounding sea take on a tranquil, timeless atmosphere.
Sagiura Port is approximately 50 minutes by car from Izumo Airport, about 35 minutes by car from JR Izumoshi Station, and approximately 20 minutes by car from Izumo Taisha.
Combining a visit to Sagiura with a trip to Izumo Taisha allows travelers to experience a different side of the Izumo region, where mythology, maritime history, traditional culture, and natural scenery are closely intertwined.
Sagiura Port brings together the history of Kitamaebune trade, ancient mythology, spectacular coastal scenery, and the quiet daily life of a traditional fishing village.
The old merchant houses and sailors’ inns, red Sekishu roof tiles, historic mooring marks, sacred shrine, sea caves, and traditional festivals each tell a different part of the story of this remarkable coastal community.
For travelers looking beyond the major sights of Izumo, Sagiura offers a chance to slow down and discover a quieter side of Japan. A walk through the historic streets, a hike along the coastline, or a boat ride into the sea caves can reveal the enduring relationship between the people of Sagiura and the sea.
With Izumo Taisha only about 20 minutes away by car, Sagiura is an ideal place to add to an Izumo sightseeing itinerary and experience the region’s culture and natural beauty from a different perspective.
