Setouchi Shimanami Kaido: The Ultimate Guide for International Cyclists

To all travelers eager to experience Japan's breathtaking landscapes firsthand: Did you know there's a cycling road hailed as "Japan's most popular"? It's the Setouchi Shimanami Kaido. Cycling through the stunning archipelago of the Seto Inland Sea and crossing its magnificent bridges offers a truly unparalleled adventure. In this article, we will delve into the unparalleled charm of the Shimanami Kaido, what you can experience there, and why your guide is essential to maximizing this extraordinary journey.

Why the Shimanami Kaido is "Japan's Most Popular"

Breathtaking Archipelago and Bridges of the Seto Inland Sea

The Shimanami Kaido, officially known as the Nishiseto Expressway, is a scenic road approximately 60km long that connects Onomichi City in Hiroshima Prefecture and Imabari City in Ehime Prefecture across the Seto Inland Sea. However, as a cycling route, it extends to about 70km because cyclists ride around the perimeter of each island after descending from the bridges. This route connects six islands in the Seto Inland Sea with seven magnificent bridges , earning it the nickname "Bridge Museum" due to its diverse structures. The bridges include Shin-Onomichi Ohashi, Innoshima Ohashi, Ikuchi-bashi, Tatara Ohashi, Omishima-bashi, Hakata-Oshima Ohashi, and the Kurushima Kaikyo Ohashi, the world's first triple suspension bridge. These beautifully engineered bridges offer spectacular views, providing an exhilarating sensation as if you are cycling directly on the sea.

Perfect Infrastructure for Cycling

The Shimanami Kaido is globally renowned as a "cyclist's sanctuary" , a reputation earned by its perfect cycling-specific infrastructure. It features dedicated cycling paths, a rarity in Japan , with a clear "blue line" painted on the road surface to guide cyclists along the main route.Along the route, there are numerous rest areas and supply points for cyclists. Local residents provide "Cycle Oases" , offering not only restrooms and rest areas but also free air pumps and water refill services. Additionally, roadside stations (Michi-no-Eki) and convenience stores are scattered along the way, allowing for hydration and energy replenishment. Furthermore, a convenient "luggage delivery service" is available, allowing you to enjoy cycling without the burden of heavy bags. This service, provided by Sagawa Express, delivers luggage between partner accommodations on the same day, enabling you to cycle light.

The Charm of "Each Island"

The true allure of the Shimanami Kaido extends beyond just cycling. Each island along the route possesses its own unique culture, history, and rich culinary delights. For instance, on Ikuchijima Island, you can witness stunning sunsets at "Setoda Sunset Beach" or immerse yourself in art and history at the "Kosanji Museum" with its vibrant architecture and the marble garden of "Hill of Hope for the Future".Omishima Island is home to "Oyamazumi Shrine," revered as the "Chief Guardian of Japan," where you can admire a 2,600-year-old camphor tree and national treasure armaments. On Hakatajima Island, you can enjoy a unique experience interacting with dolphins at "Dolphin Farm Shimanami". At roadside stations and cafes along the cycling route, you can savor local delicacies unique to the Seto Inland Sea, such as fresh seafood bowls, tai-meshi (sea bream rice), and sweets or gelato made with local citrus fruits. Imabari's local specialty, yakibuta tamago meshi (roast pork and egg rice), is also highly recommended.

Unique Experiences of Shimanami Kaido Cycling

Island-Hopping Adventure

Cycling the Shimanami Kaido is not just about reaching a destination; the true joy lies in stopping and exploring each island. The approximately 70km route offers diverse courses suitable for all levels, from beginners to advanced cyclists , allowing you to discover the islands' charms at your own pace. Bicycles can be rented at numerous rental cycle terminals along the Shimanami Kaido. A wide variety of bicycles are available, from city cycles to sports-type cross bikes, electric-assist bicycles, E-bikes, and tandem bicycles , with one-way drop-off possible at many terminals. For accommodation, there are diverse options scattered across the islands, ranging from traditional minshuku (guesthouses) to modern hotels and unique cyclist-friendly guesthouses. Some facilities even offer indoor bicycle parking and repair spaces , ensuring a comfortable stay for cyclists.

Scenic Views from the Bridges

The highlight of the Shimanami Kaido is undoubtedly the views from the magnificent bridges connecting the islands. The Kurushima Kaikyo Ohashi is the world's first triple suspension bridge, offering panoramic views of the Seto Inland Sea's rapid currents and beautiful archipelago from above.The Tatara Ohashi, with its elegant form, is one of the symbols of the Shimanami Kaido, often called the "Bridge Museum".The exhilaration of cycling across these bridges is a unique experience found nowhere else. The sensation of being high above the sea, feeling the wind as you pedal, will create unforgettable memories for any cyclist.

Immerse Yourself in Local Food and Culture

Stopping at each island along your cycling journey allows you to experience the local food and culture unique to that land. The Seto Inland Sea is a treasure trove of citrus fruits, with lemons being particularly famous. In addition to fresh seafood bowls and tai-meshi , be sure to try the gelato and sweets made with local ingredients.Furthermore, the small shrines, temples, and historical buildings you encounter while cycling also enrich your Shimanami Kaido journey. Visiting historical power spots like Oyamazumi Shrine or delving into the history of the Sengoku period at the Murakami Kaizoku Museum offers plenty of enjoyment beyond just cycling.

Why a "Guide" is Indispensable for Foreign Travelers

While the Shimanami Kaido is a magnificent destination, foreign visitors may encounter several challenges.

Information and Access Challenges

Multilingual support for rental bicycle procedures, accommodation bookings, and detailed information about each island can be insufficient , making it difficult for foreign travelers to gather information and plan independently. Specifically, there is a noted lack of English information regarding boat timetables and whether bicycles can be loaded onto boats.Moreover, information on rinko (transporting bicycles on public transport, which often requires disassembling and bagging the bicycle) and emergency procedures (such as punctures, sudden illness, or bad weather) is often not adequately provided to foreign visitors.

Optimizing Route Selection

While the Shimanami Kaido offers diverse cycling routes, proposing the optimal route based on individual fitness levels and preferences—whether prioritizing "scenic views," "gourmet experiences," or "cultural immersion"—can be challenging without local knowledge.Furthermore, changes in wind direction or weather may necessitate route adjustments , a decision that is difficult to make without an experienced guide.

Language Barrier and Local Interaction

Many local eateries primarily cater to Japanese customers, often lacking English menus or clear indications for vegetarian/vegan options, which can pose a challenge for foreign travelers with specific dietary restrictions.Communication with locals and ordering at shops can also be hindered by language barriers.Additionally, one of the Shimanami Kaido's charms, the "simple warmth of its people" and access to "Super Local" hidden spots, is highly likely to be missed without a guide.

Planning Your Shimanami Kaido Cycling Trip: Tips and Precautions

Best Season

Bicycle Preparation

The Shimanami Kaido offers a variety of bicycle rental services.If you are concerned about your physical stamina, an electric-assist bicycle (E-bike) can be a very beneficial option.However, E-bikes typically have higher rental fees and may be subject to same-day return policies or not allow one-way drop-offs, so it's essential to confirm these details in advance.For popular models or during peak season, advance reservations are indispensable.If you bring your own bicycle, be aware that rinko (disassembling and bagging your bicycle) may be required for public transport, so check the rules for each mode of transportation.

Accommodation

Along the Shimanami Kaido, various types of accommodation are available, including guesthouses, hotels, and traditional Japanese inns (ryokan).Early booking is essential, especially during peak seasons. While many foreign visitors tend to make day trips , staying for multiple nights allows for a deeper immersion in the islands' culture and charm. We recommend taking your time to explore at a leisurely pace, combining cycling with other activities.
