Picture cycling along high white bridges over open water, lush green islands floating in every direction — this 70 km route links Onomichi (Honshu) to Imabari (Shikoku), hopping 6 islands, with a dedicated bike lane on every bridge. Finish it in a day, or split it over two and overnight on an island with no rush.
Straight up: if you've ever dreamed of doing one beautiful bike ride in your life, the Shimanami Kaido belongs near the top of the list. It's a roughly 70-kilometre cycling route linking the town of Onomichi on the island of Honshu (Hiroshima Prefecture) across the Seto Inland Sea to the town of Imabari on Shikoku (Ehime Prefecture). Along the way you hop across 6 islands, crossing one big sea-spanning bridge after another — and the best part is that every bridge has a separate cycling lane, so you ride safely with no jostling for space with cars.
The route is fairly flat, and a regular rider can finish it in around 6–8 hours in a single day. But honestly, the magic here is in taking it slow — pulling over for a lemon gelato by the road, stopping at an island temple, photographing a bridge in the late-afternoon light. Plenty of people split it over two days with an overnight on an island. On this page we'll cover everything from the stops you shouldn't miss to renting a bike, getting in and out, and where to stay on both ends.
The main route runs through Mukaishima → Innoshima → Ikuchijima → Omishima → Hakatajima → Oshima before crossing the Kurushima-Kaikyo Bridge into Imabari. Use this table to see what each leg has in store (distances are approximate).

People who finish the ride all say the same thing: "I wish I'd stopped more." These are the places worth budgeting time for — the legendary bridges, the island temples, and the roadside snacks.
The star of the show is the riding itself — the route is marked with a blue line the whole way, and every bridge has a looping access ramp and a bike lane separated from traffic. A regular rider finishes in 6–8 hours, and the terrain is fairly flat with climbs only on the bridge approaches. An e-bike makes those climbs much easier.

🌉 Near Imabari2
This is the highlight people save for the final stretch — three consecutive suspension spans totalling about 4 kilometres, often cited as the longest suspension bridge for cyclists and pedestrians in the world. You ride high above a channel with swirling tidal currents below, the view wide open on both sides — you'll want to stop and shoot.
Ehime (Shikoku) Guide →A sleek, elegant cable-stayed bridge, its cables fanning out from tall towers like wings. It was once the longest cable-stayed bridge in the world, at about 1,480 metres. The fun bit is at the base of the towers — a "whispering wall" where a clap or a shout echoes up the pillars. Kids love it.
Chugoku Region →A midway stop that surprises a lot of people — a vividly colourful temple a businessman built in memory of his mother, with buildings modelled on famous temples from across Japan. Above it sits "Miraishin no Oka," a hill of pure white marble sculpture that looks out over the Seto Sea — it feels like stepping into another world.
Hiroshima Guide →An ancient shrine revered by warriors of old, set beneath camphor trees hundreds of years old in the shrine grounds. The atmosphere is cool, shaded, and quiet — a restful midway stop that's a change from the open sea views all along the route. Omishima is also known for its citrus and its little roadside cafés.

🚢 Honshu · start6
Before or after the ride, allow half a day to wander Onomichi — a small port town on the hillsides above the channel, with a temple walk climbing the slopes, lanes where cats roam, and viewpoints looking across the strait to the route's first island. It has a relaxed, retro feel and makes a warm starting point.
Hiroshima Guide →An underrated joy here is the roadside food — all along the route there are rest stops (michi-no-eki) selling lemon and citrus gelato from the island orchards, fresh lemonade, and local snacks, the perfect reward for tired legs. Many have a terrace where you can sit and look out over the sea and catch your breath.
Japan Nature Escapes →The Shimanami Kaido has two heads — Onomichi (the Honshu side) and Imabari (the Shikoku side). Most people start at Onomichi and finish at Imabari. Bus and ferry timetables can change, so check the latest before you go.
Take the shinkansen to Fukuyama Station, then a local train to Onomichi Station, about 20 minutes. From Hiroshima to Fukuyama is around 25 minutes; from Osaka around 1 hour. The Onomichi U2 bike rental is near the station and the ferry pier.
The Shikoku side is reached via Matsuyama, Ehime's biggest city. Take the Yosan Line train from Matsuyama to Imabari, about 40 minutes to an hour. Finish at Imabari, then ride the train on into Matsuyama to soak at Dogo Onsen.
There's no direct train between Onomichi and Imabari, but express buses (such as the Fukuyama–Imabari service) run along the route, and ferries connect the islands. Handy if you want to ride only part of the way and continue by bus, or if you're carrying a big suitcase (you can forward luggage ahead at some points).
If you ride it in a day, base at the start (Onomichi) the night before, then the finish (Imabari/Matsuyama) the night after. But if you'd rather take it slow, an overnight on a midway island is the highlight most people love best.
See clearly how the route runs from Onomichi (the Honshu side) down to Imabari (the Shikoku side), crossing the Seto Sea over island after island and bridge after bridge — the pins are in riding order.
