The Oki Islands are a group of remote islands located in the Sea of Japan, 40-80km off the mainland Shimane Prefecture, Japan in the southwest of Honshu Island.

The island group consists of four inhabited islands:

The three Dozen Islands (make up the Dozen Caldera) and can be easily reached from each other by ferry

and the larger, more distant

Dogo Island is around half an hour by jetfoil, or 1 hour - 1 hour and 30 minutes by regular ferry from the Dozen Islands.

These islands are one of the lesser-known travel destinations of Japan, but are a surprising discovery for those seeking a change of pace and some of the most spectacular coastal scenery to be found on the Japanese Archipelago. The charm of these islands lies in their remoteness from mainland Japan; the adventure in getting there on the ferry or by plane, and experiencing the distinct island way of life, unique culture and traditions, and of course the beautiful coastal scenery of volcanic islands. The natural beauty and geologic importance of the islands has been recognised by UNESCO. The islands were designated as a UNESCO Global Geopark[4] in 2013. The islands are also part of the Oki-Daisen National Park[5].

The Oki Islands are volcanic (now extinct), created around 5-6 million years ago in the Sea of Japan, and are very mountainous, with stunning eroded coastlines. The majority of the population is settled small and picturesque settlements nestled in between mountains along the coast. Many of these settlements are quite isolated, and although modern roads provide easy access all around of the islands, distinct identities and festivities have been preserved.

The overall population of the islands is around 21,600, with 15,500 living in Dogo Island, 3,100 in Nishinoshima Island, 2,300 in Nakanoshima and 650 in Chiburijima Island.

Though the islands have been in contact with the mainland throughout history, their isolation and mountainous terrain have helped preserved many ancient cultures and traditions, many of which are unique, or have disappeared in other parts of Japan. They are most well-known for having been designated ‘islands of exile’ where up to 2,000 trouble-making nobles were sent from the 8th to the 12th century.


Ancient History[edit]

The islands have a long and rich cultural heritage that has been preserved throughout the ages. It is uncertain when the islands were discovered, however obsidian excavated from the islands was used to make tools and traded in particular around the Chuugoku Region since up to 30,000 years ago. Pieces of this ancient history have been discovered in ancient Izumo-style tombs, shrines to old animistic gods, and festivals that stem from ancient animistic beliefs. The islands are also mentioned in the oldest written chronicles of Japan, the Kojiki and the Nihon Shoki (early 8th century). In the ancient mythology that describes the creation of the Japanese Archipelago, the Oki Islands were created third, perhaps revealing the islands' significance in ancient times.

Islands of Exile[edit]

Under the new set of laws implemented by the Ritsuryō (historical law system) the Oki Province was designated 'islands of exile' from the 7th century to the 19th century. Noblemen who were on the losing end of the power struggles were banished to the islands where they would live out their sentences peacefully. Among the exiled noblemen were two defeated emperors Emperor Gotoba who was exiled from the capital Kyoto in 1198 and remained in Oki until his death in 1239, and Emperor Godaigo who was exiled in 1331 but escaped in 1333. Many other political figures such as Ono no Takamura were also exiled during this period. These figures were exiled along with their entourages, and brough a different class of culture which contributed to the mix of culture on the Oki Archipelago and has left behind a wealth of cultural heritage.

Kita-mae-bune (Northern-bound Ships)[edit]

The islands became part of the feudal Matsue Domain in the Edo Period (1603 - 1868). During this time the islands flourished as a port of call for the revolutionary Kita-mae-bune (Northern-bound Ships) shipping route that was prosperous from the Edo to the Meiji Period. The advanced kita-mae-bune ships allowed merchants to travel from Osaka by way of the Kanmon Straits (the sea separating the Kyushu and Honshu Islands) up to the northern island Hokkaido. Trading occurred at the ports along the way. Oki experienced a great deal of business as merchants stopped in the islands to replenish supplies and ‘wait for the right wind’. As a result many sailors would remain for quite some time bringing different culture to the islands. Visitors to Dogo Island in particular will enjoy the remnants of a once prosperous port town whilst walking around the river and the winding streets of the Saigo Port area, or by taking the Kappa Yuransen Sightseeing Boat.

Independence Movement[edit]

In 1868 there was an independence movement on Dogo Island and the officials of the Matsue Domain were thrown out and sent back to the mainland without bloodshed. Dogo Island was self-governed for 80 days until the position was reinstated by military intervention shortly after.

Oki and Haibutsu Kishaku[edit]

The anti-Buddhist movement that took place during the Meiji Restoration at the end of the 19th century was taken seriously in Oki, and in Dogo Island all of the Buddhist Temples were completely destroyed. Consequently, many historical records and cultural artifacts from that time were also lost.

Oki and the Mainland[edit]

Following the state reforms of the Meiji Restoration and the establishment of the prefectural system Oki's relationship with the mainland was somewhat tumultuous. It was initially its own prefecture but was later merged with Hamada, first as Omori Prefecture and then Hamada Prefecture. It later it was merged with Shimane Prefecture, and then briefly became part of Tottori Prefecture, only to become part of Shimane Prefecture once more in 1881. However, having established strong links to the mainland of Japan during the time of the Kita-mae-bune trading route, the islands have had a relatively swift transfer of information and goods from mainland Japan. As expressed in his in his novel ‘Glimpses of an Unfamiliar Japan’, Lafcadio Hearn (Yakumo Koizumi), an international writer who became a Japanese citizen, visited Oki in 1892 and was surprised to find it was much more modern than he expected from remote islands.

The entire population of the Oki Region is at present around 21,600, however in 1950 it was recorded as being around double this.

  • Takuhi Shrine, the oldest shrine building in the Oki Islands. This incredible shrine is worth the short hike up Mt. Takuhi (about 15 minutes from the car park), it is built partially in a cave. The journey up offers some great views of the sea and port entrance. Takuhi Shrine is dedicated to the deity of safe sea voyages and people have come to this shrine to pray for safety at sea since long ago. It has been designated as an Important Cultural Property of Japan.

Chiburijima Island (Chibu Village)[edit]
