Setouchi Region - Basic Information

Prefectures comprising the Setouchi region.

Setouchi refers to the region in western Japan that surrounds the Seto Inland Sea. It is composed of seven prefectures: Hyogo, Okayama, Hiroshima, Yamaguchi, Tokushima, Kagawa, and Ehime.

With 700 islands dotting the sea, Setouchi is famous for its stunning scenery. In 1860, the German geographer Ferdinand von Richthofen remarked that the scenery was unmatched anywhere else in the world.

The Setouchi has plenty of historical and cultural sites, including the Hiroshima Peace Memorial Museum and Itsukushima Shrine. However, it's also home to the Setouchi Triennale, the largest contemporary art festival in Japan, held every three years.

The History of Setouchi


Miyajima Island, home to Itsukushima Shrine

The Seto Inland Sea has long been the center of Japan's shipping industry.

During the late Heian Period (794 - 1185), Tairo no Kiyomori—a powerful military leader—established a port to trade with the Song Dynasty in China. Then during the Edo Period (1603 - 1868), several ports were built for cargo ships connecting Osaka with northern Japan.

Since the Meiji Era (1868 - 1912), the region has flourished as a center for shipbuilding. The town of Kure is also the backdrop of the hit anime movie "In This Corner of the World."

With its rich history and culture, Setouchi has a variety of unique places that are worth visiting.

Getting Around Setouchi


If you plan on traveling by train, we recommend using the JR-West Rail Pass.

For those with extra time, we recommend crossing the Seto Ohashi Bridge between Kojima, Okayama, and Sakaide, Kagawa. It is one of the world's largest road-rail bridges. Enjoy the view of the Seto Inland Sea as you travel across by train or car.

Boats are another mode of transportation. You can take a ferry out to Shodo Island and Naoshima Island or reach smaller islands via a high-speed craft. Another option is booking a cruise, such as guntû. You are sure to have an unforgettable experience!
