SETO INLAND SEA

The Seto Inland Sea lies between three of the four main islands of Japan (Honshu, Shikoku and Kyushu), extending roughly 450 km east to west and anywhere from 15 km to 55 km south to north. This region, which is often referred to as Setouchi in Japanese, is noted for its scenic beauty. Islands lie scattered across the sea’s tranquil waters, white sandy beaches rim its shores, pine groves provide welcome shade, and rice paddies terrace the hillsides. The first Westerners to gaze upon the area after it was opened in the mid-nineteenth century, including Thomas Cook and Philipp Franz von Siebold, praised its charms in their travelogues. In 1934, the section of the Inland Sea bordered by Kagawa, Okayama and Hiroshima prefectures became Japan’s first national park.

Since ancient times, the Seto Inland Sea has served as a strategic shipping route, carrying not only goods but also peoples and cultures to and from the Kansai area. The islands and coastal regions welcomed this influx of knowledge while, at the same time, developing their own unique culture and traditions. The fact that the region was formed through the workings of both man and nature is one of its many charms.

During the 1960s, Japan underwent rapid economic growth, but the development of large scale industries in the Setouchi region exacted a heavy toll in the form of environmental pollution. The rich historical and cultural legacy of the Seto Inland Sea thus reflects both the positive and negative aspects of humankind’s interaction with the natural environment.

NAOSHIMA

Naoshima is known internationally as a focal point for contemporary art with museums designed by Tadao Ando and site specific works by such artists as James Turrell, Walter De Maria and Hiroshi Senju. The name Naoshima, which literally means “gentle island”, was coined by Emperor Sutoku (1119-1164) when he was exiled here in 1156 and was bestowed as a tribute to the islanders’ honesty and openness.

Naoshima covers an area of almost 8 km2 and has a population of about 3,200 people. Located on the Seto Inland Sea, which is a strategic trade route, Naoshima developed a powerful navy under the ruling clan in the 15th century. Subsequently, many islanders engaged in the lucrative marine cargo trade.

Theater arts blossomed during the 19th and early 20th centuries, a legacy that remains in the form of Naoshima Onna Bunraku, a female-only puppet theater. Fishing, another core industry, remains strong, and yellowtail and seaweed farming continue to support the island economy along with art-based tourism and a metal refinery on the north end of the island.

TESHIMA

Located near Naoshima, the island of Teshima is home to the Teshima Art Museum and a popular destination for those seeking a different side of Japan. The resident population is about 1,000 people, and signs of human habitation date back at least 9,000 years. True to its name, which means “bountiful island”, Teshima is blessed with a plentiful supply of spring water, which is essential for irrigated rice farming. It was one of the few islands that produced enough rice to export to other areas. Terraced rice paddies still cover the island’s lower slopes while thick woods rise up the steep hill known as Danyama in the island’s center.

Stone quarrying was the primary industry for a thousand years, surpassing fishing and shipping, and Teshima tuff can be found in historic buildings and structures throughout western Japan. Dairy farming took off from the mid-nineteenth century, and milk from local cows helped feed infants in a nursery established for orphans after World War II.

More recently, Teshima became the center of a major scandal involving the worst case of illegal dumping of industrial waste in Japan. A decades-long grassroots movement pushed the nation to enforce tighter environmental standards, and the hazardous waste, consisting mainly of shredded byproducts from automobile manufacturing, is being recycled into slag in a special plant on Naoshima.

MEGIJIMA

The closest island to Takamatsu, Megijima is less than 3 km2 in size and has a population of just 170. Stone walls known as Ohte rise 3 to 4 meters in height along the edge of the village. These were originally built more than 150 years ago to protect island homes from winter gales, and they give the community a unique fortress-like appearance.

An observation deck on the island’s highest point offers a panoramic view of the Seto Inland Sea. Nearby is an impressive cavern, perhaps used by pirates long ago but now a popular tourist spot linked to the ogres’ den from Momotaro, a Japanese folktale about a hero born from a peach. This fact explains the many ogre motifs on the island.

In the spring, the slopes blush a delicate pink as thousands of cherry trees blossom, while in summer, the island’s beaches attract many swimmers and campers. Megijima also offers excellent recreational fishing.

Every other year, the island hosts a grand shrine festival in which a large float bearing young taiko drummers is carried into the sea in a demonstration of courage.

OGIJIMA

ust 1 km north of Megijima lies the even smaller island of Ogijima (1.38 km2) with a population of about 180. Narrow lanes weave through the picturesque village that clings to the steep hillside. Lacking flat land suited for rice farming, the islanders raised cows instead and rented them out as plow animals to farmers on other islands in return for rice. This practice continued until the early 1950s.

Toyotamahime Shrine, which is visible halfway up the hill behind the port, is dedicated to a deity that ensures safe childbirth, and many expecting couples used to come here to pray. On the northern tip of the island stands an elegant stone lighthouse built in 1895. In 1957, this was made famous by a popular Japanese movie, Times of Joy and Sorrow. It is now a museum. Volunteers planted tens of thousands of Narcissus bulbs on the slope nearby, and these draw crowds of flower-loving Japanese when they bloom in February.

SHODOSHIMA

Shodoshima is the second largest island in the Seto Inland Sea with a population of 30,000. According to Japanese mythology, it was the tenth island to emerge from the sea. The climate and stunning setting coupled with a thriving olive industry are reminiscent of the Mediterranean, and people throng here to enjoy its beaches, resorts and scenic sights, including the elusive Angel Road sandbar and the spectacular Kankakei Gorge. For the same reason, the island has become a prime movie location.

Shodoshima has a rich history and tradition. Rural kabuki thrived here for several centuries, with 30 theaters during its heyday. While only 2 remain, the traditional thatched-roofed structures continue to host annual performances staged by the local community.

Local industries were developed in harmony with nature and still retain time-honored traditions. Shodoshima was the first place in Japan to successfully cultivate olives about 100 years ago, while local soy sauce manufacturers still use production techniques dating back four centuries. Other specialty products include sesame oil and somen noodles.

OSHIMA

Oshima is located just 8 km from Takamatsu Port. It was once two tiny islands, but the channel between them gradually filled with sand, joining them together to make a single island of less than one square kilometer. During a historic battle between the Genji and Heike clans near Takamatsu in the 12th century, the corpses of defeated Heike warriors washed up on Oshima’s west shore where the islanders buried them. Pines grew up over their graves, and a grove of trees marks the spot to this day.

In 1909, the island became a sanitarium for people with Hansen’s disease (leprosy). Fear and prejudice led the Japanese government to adopt a policy of segregation, and victims of the disease were torn from their families and forced to live in isolated colonies like Oshima. The law stipulating forced quarantine was only repealed in 1996, with further legislation following in 2008. All residents of the Oshima sanitarium were cured many years ago, but the facility provides continued care and support for those who need it, as well as educational activities to raise public awareness of the disease and its tragic history.

INUJIMA

Like neighboring Naoshima, this island is drawing attention for intriguing works by some of Japan’s foremost contemporary artists and architects, such as Kazuyo Sejima and Hiroshi Sambuichi. A quick 8-minute ferry ride from Hoden Port in Okayama, Inujima is a tiny island (area: 0.54 km2) with a population of just 50 people and can be explored entirely on foot.

In the past, the island’s high quality granite was quarried to build the castles of Edo, Osaka and Okayama. It continued to be sought after into the early 20th century. In 1909, a copper refinery was also established, and the island’s population swelled to 3,000 during the decade of peak production. When the refinery closed and the stone industry declined, however, the population dropped drastically. The art sites, however, are restoring life to the island as well as an appreciation for the beauty of this natural setting.

SHAMIJIMA

Shamijima was once located 4 km from the shore but in 1967, the channel was filled under a land reclamation project and Shamijima was an island no more. The history of human habitation is ancient, and pottery shards and stone implements found here date back to the Jomon period (12,000-300 BC).

There are also at least nine ancient burial mounds known as kofun on the hill at the island’s southern tip. The island appears by the name of Samine in a well-known waka poem penned by the famous poet Kakinomoto Hitomaro around 690 and contained in the Man’yoshu, Japan’s oldest poetry anthology.

In 1988, the graceful Seto Ohashi Bridge was completed, and Shamijima offers a striking view of this wonder of modern technology, the world’s longest two-tiered bridge. On the island’s west shore lies a sheltered beach that is highly popular in summer and a great place to watch the Inland Sea’s magnificent sunsets.

HONJIMA

Situated in the Shiwaku islands, Honjima served as the political center for the Shiwaku Suigun, a maritime force that controlled the surrounding sea for several centuries. Tricky currents and hidden shoals make navigation in this region treacherous, and the local people were both expert navigators and shipbuilders. Japan’s land-based rulers were so reliant on them for shipping and naval protection that in the late 16th century they granted them permission to rule the Shiwaku islands through a collective of 650 local men known as ninmyo. In the mid-nineteenth century, it was Shiwaku seamen who manned the Kanrinmaru, the first ship to carry Japanese across the Pacific to acquire the fruits of Western learning.

Honjima’s past glory is reflected in the elegant Edo and Meiji period buildings, of which over 100 have been restored in the Kasaoka district. Kinbansho, the former seat of island government, has been converted into a museum that houses such precious artifacts as documents stamped with the seals of the three most influential leaders of the late 16th century: Nobunaga Oda, Hideyoshi Toyotomi and Ieyasu Tokugawa.

TAKAMIJIMA

Takamijima lies to the west of Takamatsu city and can be reached from Tadotsu Port. Takamijima’s harbor and two small settlements are clustered around the island’s southern tip at the foot of a steep 300-meter hill. There is not much farmland, but for several centuries the island supported up to 1500 inhabitants who were engaged in shipping and fishing. More recently the pyrethrum plant, a natural insecticide, was cultivated for export.

The beautiful but slowly decaying houses that cling to the steep slopes and the sturdy stone terraces that support them serve as a poignant tribute to the building skills of the Shiwaku seamen. The unusual custom of dual graves (one grave for the body and another at which the family prays) is still practiced here.

The population has declined drastically in recent years, and cats now outnumber residents. Every year in September, however, people gather from neighboring communities to participate in a joint athletic meet that brings the quiet island to life.

AWASHIMA

Located about 50 km west of Takamatsu, Awashima flourished from the 17th to 19th centuries as a port of call on the Kitamaebune shipping route, which ran from Osaka through the strait north of Kyushu and up the coast to northern Japan.

Formed by three small islands linked by sandbars, Awashima is shaped much like a ship’s propeller. Time passes slowly, providing visitors with a welcome refuge from a busy modern lifestyle.

At night, the star-spangled sky coupled with the flickering lights of passing ships and the blue luminescence of sea fireflies presents a breathtaking light show. The sea fireflies illuminate the sea from late May to early October, and are at their peak in the early fall.

Japan’s oldest national marine school was established here in 1897 and produced superior sailors for 90 years until it closed in 1987. The school building has since become part of the Awashima Ocean Memorial Park and serves as the island’s symbol. Awashima is a short 15-minute ferry ride from Suda Port in Takuma and has a population of 300.

IBUKIJIMA

Ibukijima is located about 60 km west of Takamatsu and can be reached from Kanonji Port. The island rears up from the sea to form a rough tabletop of andesite and granite about 1 km2 in size. As the coastline is mainly cliffs, the population of 600 is concentrated at the top. The slope extending up from the port is called shinzo-yaburi-zaka, meaning “heart-rending” hill, a name indicative of the arduous climb to the top.

The island’s prosperous fishing industry uses a combination of cast nets, small-scale trawl nets, and fixed shore nets. Ibuki Iriko (dried sardine fry), which is processed on the island immediately after being caught, is the most sought after brand in the country. The rough and simple Ibukijima dialect fascinates linguists because it is the only dialect in Japan that preserves many expressions and honorifics from the 8th century.

TAKAMATSU

Situated roughly 500 km west of Tokyo, Takamatsu is the capital of Kagawa prefecture and the second largest city on the island of Shikoku with a population of 420,000 people. The city developed as a castle town from 1588 and had one of Japan’s three largest sea castles. Although the castle keep was dismantled in the 19th century, the original turrets remain as do some of the seawater moats, which are now extremely rare in Japan.

From the 16th to 19th centuries, Takamatsu developed into a major commercial and administrative center under the Tokugawa government. With the development of harbor facilities and a railroad in the late 19th century, Takamatsu Port became known as the gateway to the island of Shikoku. The port continues to serve as an important hub for both passenger and cargo ships between Shikoku and the many islands and ports on the Seto Inland Sea.

UNO PORT

Uno Port is located in Tamano City on the southern tip of Okayama Prefecture. The city stretches 44 km east to west along a scenic coastline and has a population of 62,500. A moderate climate and sheltered inlets and bays makes Tamano an ideal port city, and its bustling harbor has prospered for centuries.

Uno Port is situated near the city center and was the main terminus for ships sailing from Shikoku to the island of Honshu until the completion of the Seto Ohashi Bridge in 1988. The port continues to fulfill this role for sea traffic from many islands on the Seto Inland Sea, including Naoshima, Teshima and Shodoshima.

Shipbuilding and mining underpinned the development of Tamano, and its townscapes still preserve many quintessential features of a typical shipbuilding town.
