Why go
The Shimanami Kaido is the only road link between Honshu and Shikoku that you can cross by bicycle. A separate cycle path runs beside the expressway over each bridge, so you ride high above the Seto Inland Sea, then drop onto quiet island roads past fishing ports and temples. Japan named it a National Cycle Route in 2019.
The route
The classic ride runs from Onomichi in Hiroshima to Imabari in Ehime, about 70 km by the bike route, across Mukaishima, Innoshima, Ikuchijima, Omishima, Hakatajima and Oshima. Blue lines painted on the road mark the way. Riders take a short ferry from central Onomichi to Mukaishima, because the Shin-Onomichi Bridge has no cycle path and the Onomichi Bridge is narrow and busy. On Ikuchijima, the town of Setoda has Kosanji Temple and the Hirayama Ikuo museum. The finale is the Kurushima Kaikyo Bridge, three suspension bridges in a row with a total length of 4,105 m, crossing the strait from Oshima to Imabari. Kirosan Observatory on Oshima, at 307.8 m, looks straight down on it.
When to go
The route is ridden all year in a mild climate. Summer brings heat, so carry plenty of water, and spring and autumn can be windy on the open bridges.
Getting there
The rental terminal in Onomichi is about 150 m from Onomichi Station, and a limousine bus from Hiroshima Airport takes about 50 minutes. At the far end, the Imabari Station terminal is a few steps from the west exit, and highway buses run from Imabari to Hiroshima and Fukuyama.
Permits and booking
No permit is needed. Bridge tolls for bicycles, normally about 500 yen in total, are waived under the Shimanami Cycling Free scheme, which Hiroshima Prefecture has extended to 31 March 2028. The Onomichi ferry costs 110 yen with a bike. Cyclists keep left, as traffic does, and riding on the right counts as wrong way. Since April 2023 every cyclist is asked by law to try to wear a helmet, with no fine. Since 1 April 2026, riders aged 16 and over can be fined on the spot, for example for phone use or riding without lights at night.
How hard it is
Gradients are gentle, because the ramps up to each bridge were built at small inclines, though every bridge still means a climb from sea level. The Japan National Tourism Organization puts the ride at about 4 hours for experienced riders and up to 10 for beginners. The path is well marked and maintained.
Where to sleep
Most riders sleep in Onomichi or Imabari and do the ride in a day. For two days, there are minshuku guesthouses and campsites on the islands, and Sunrise Itoyama, the big cycling terminal by the Kurushima Kaikyo Bridge, has rooms.
Tips
- Book a rental ahead in busy seasons. About ten terminals let you drop a standard bike at a different one, while tandems must go back where they started.
- Stop at an island terminal and take a bus onward if your legs give out, which the rental system allows.
- Carry front and rear lights if you might finish after dark.
