The Nishiseto 西瀬戸 Expressway, commonly known as the Setouchi Shimanami Kaido 瀬戸内しまなみ海道 Expressway, links Onomichi 尾道, Hiroshima Prefecture 広島県, with Imabari 今治, Ehime Prefecture 愛媛県. It is a 60 kilometer-long highway that links the islands of the Seto Inland Sea with nine individual bridges. There are two other land connections between Shikoku and Honshu, but the Shimanami Kaido is the only one accessible by bicycle and on foot.
Each bridge consists of a vehicle road and a pedestrian walkway, enabling people to enjoy the sea breeze as they walk or cycle across the bridge. While viewing the continually changing scenery of Setouchi, you can enjoy cycling over the sea on the seven unique bridges that connect the islands.
The area along the Shimanami Kaido linked by bridges is blessed by the temperate climate of the Seto Inland Sea. There is much to delight visitors, including the loveliness of nature on the islands, sites of history and culture, and a variety of activities.
The Shimanami Kaido begins on Honshu in Onomichi City. It then leads across the six islands of Mukaishima 向島, Innoshima 因島, Ikuchijima 生口島, Omishima 大三島, Hakatajima 伯方島 and Oshima 大島, before terminating on Shikoku in Imabari City. The route was opened in 1999, so the bridges are modern. Along the way, travelers can enjoy the beautiful scenery of the Seto Inland Sea and the islands’ small towns.
In addition to the scenery, there are several other attractions on the way between Honshu and Shikoku. On Ikuchijima Island there is the Hirayama Museum 平山美術館, which is dedicated to one of Japan’s most famous painters, Hirayama Ikuo 平山郁夫, who was born on the island. Nearby is Kosanji 耕三寺 temple, which was built by a rich business man for his mother. There are a number of minshuku and camping grounds on the islands for those who want to extend the journey over multiple days.
Cycling is a popular means of transport experiencing the Shimanami Kaido. The bicycle route is well marked and maintained, and diverges from the expressway on the islands. The ramps leading up to the bridges were built at small inclines with cyclists in mind. At about 70 kilometers, the bike route is a bit longer than the toll road, but because there are no large inclines, it can be comfortably completed in a day by intermediate cyclists.
Two separate bicycle rental systems are offered along the Shimanami Kaido: the public rental system features over a dozen terminals dotted along the cycling course, while a newer one is operated by bicycle manufacturer Giant with two terminals. Both systems allow tourists to rent their bicycles at one end of the route and drop it off at the other end, or – in case of the public system – to stop anywhere in between when they become tired and take a bus for the rest of their journey.
The public rental system is cheaper and offers more terminals. The rental fee is 1,000 yen per day. A 1,000 yen deposit is charged and will be returned unless you drop off the bicycle at a terminal on a different island. Various types of bicycles are available, but some of the smaller terminals may only have a limited selection. Tandems (1,200 yen per day) and electric-assist bicycles (1,500 yen for 6 hours) are available at some terminals and must be returned to the terminal from which they were rented. Advance reservations are not necessary.
The Giant rental system is more expensive and has only two terminals: one at Imabari Station and the other at Onomichi Station. Various high-quality bicycles are available to rent for 4,000 to 13,000 yen per day. Drop-off at the other terminal is only possible with road bicycles, requires prior reservation and costs an additional 3,000 yen.
Small tolls (totaling 500 yen) must be paid when crossing the bridges, not including the bridge between Honshu and Mukaishima Island, which is best replaced by a short ferry ride to/from central Onomichi (around 110 yen one way for an adult with bicycle). Note that until March 31, 2018, the tolls are waived for bicyclists as a temporary measure to promote tourism.
You can refer to the official Shimanami website for further information on Shimanami Cycling Hire & Ferry Fares.
Traveling the Shimanami Kaido is also possible by car. Expressway tolls total around 5000 yen one way. There are direct buses from Imabari to Hiroshima, Onomichi and Fukuyama.
Getting There and Around
In Onomichi the two cycling terminals are located about 150 meters from Onomichi Station 尾道駅. One is in a parking lot west of the Green Hill Hotel at the waterfront and the other, the Giant Onomichi store, is located in Onomichi U2, a redeveloped warehouse beside this parking lot. There are three ferries operating between central Onomichi and Mukaishima, the starting point of the bicycle trail.
In Imabari, the two cycling terminals are located at Imabari Station. The terminal of the regular system is located a few steps from the station’s west exit along the railway tracks, while the Giant Imabari store is located inside the station complex. Another large terminal is Sunrise Itoyama which also serves as a lodging; however, it is a bit difficult to access. There are infrequent buses from Imabari Station to the Sunrise Itoyama terminal. Alternatively, it is about a 2000 yen taxi ride from Imabari Station, or a 30 minute walk from Hashihama Station. For those who make reservations beforehand, a shuttle bus ride can be arranged.
