Shimanami Kaido: Be Swept Away by Gorgeous Views of the Seto Inland Sea

The Shimanami Kaido is a highway that connects Onomichi City in Hiroshima Prefecture located in the Chugoku region and Imabari City in Ehime Prefecture located in the Shikoku region. It is the perfect location to admire breathtaking views of various islands on the Seto Inland Sea. This article will introduce sightseeing spots along the Shimanami Kaido that you can stop by along the way.

Shimanami Kaido: A Highway Linking Islands

The Shimanami Kaido, officially called the Nishiseto Jidoshado, is a highway spanning 60 kilometers that links Onomichi City and Imabari City. Each bridge linking the islands has its own name, and they are collectively called the Shimanami Kaido. Before continuing, we would like to point out that there are special lanes for pedestrians and bicyclists to pass through the highway free of charge.

Both Onomichi and Imabari offer bike rentals and a coin-operated shower stall. This means tourists can go cycling along the sea without any advanced preparations. You can find more information on bike rentals on the Setouchi Shimanami Kaido Co-Operative Association website, which is available in several languages.

The Shimanami Kaido starts in the hilly city of Onomichi, Hiroshima Prefecture. You will first reach Mukaishima by passing the first bridge, Onomichi-Ohashi Bridge, across the Onomichi Strait. Since this bridge is narrow, it can be dangerous when crossing. However, bikers and pedestrians can use ferries to reach Mukaishima.

Onomichi is a compact city where everything is gathered in a narrow, hilly area surrounded by the sea and mountains. The most popular activity for visitors is sightseeing around historical shrines and temples.

Hassaku Jelly is made using locally-grown Hassaku oranges, a citrus fruit that is the size of a grapefruit. This is a dessert you can enjoy anywhere in Hiroshima.

Innoshima is known as the origin of Hassaku oranges. It also functioned as the ancient hub of Japanese pirates. There are many historical spots and museums related to pirates found here.

A Gigantic, Eye-Catching Suspension Bridge

When speaking about the Shimanami Kaido, one must mention the big suspension bridge that connects the islands.

Tatara Ohashi is the largest cable-stayed bridge in Japan, located between Ikuchijima and Omishima islands. A cable-stayed bridge refers to a structure that supports the crossing area with a cable built diagonally from a high tower. This design forms a beautiful triangular shape.

Kurushima Ohashi, the bridge linking Kurushima Island and Imabari City, is over four kilometers long. You can see stunning sunsets from the bridge that stretches from east to west.

Kirosan Observatory Park is a recommended spot to look out at the Kurushima-Ohashi Bridge from Oshima. The observation platform was designed by the famous Japanese architect, Kengo Kuma. It is made of wood and has a modern look. You'll marvel at the spectacular view that comes into sight upon walking up the stairs.
