The Shimanami Kaido Bikeway is a world-renowned 70-kilometer (43-mile) cycling route that traverses the Seto Inland Sea, linking Onomichi in Hiroshima Prefecture on Honshu with Imabari in Ehime Prefecture on Shikoku. This unique route is celebrated for being the only land connection between the two islands accessible by bicycle and foot, offering cyclists spectacular views from a series of six impressive suspension bridges. It's not just a path; it's an immersive journey through Japan's island landscapes, dotted with small towns, temples, and scenic overlooks.
Visitors frequently highlight the stunning panoramic views from the bridges and the well-marked, dedicated cycling lanes as major positives. Many appreciate the convenience of numerous bike rental stations and luggage transfer services, which simplify the logistics of a multi-day trip. Reviewers often describe the experience as exhilarating and peaceful, noting the fresh sea air and the opportunity to explore charming local communities. However, some sections, particularly the ascents to the bridges, can be challenging, and a few industrial areas along the route are less scenic than others.
To make the most of your ride, consider starting early in the morning to avoid crowds and enjoy cooler temperatures, especially during summer. Bringing plenty of water, snacks, sunscreen, and appropriate cycling attire is highly recommended. While the entire route can be completed in a single day by experienced cyclists, many visitors suggest allocating two days to allow for leisurely exploration of the islands, including stops at local cafes, temples, and viewpoints. Renting an electric-assist bicycle is a popular choice, particularly for those less accustomed to long-distance cycling or for tackling the hilly sections with greater ease. Reserving your bike in advance, especially during peak season, is crucial to ensure availability.
The most common starting point is Onomichi, which is easily accessible by train. From Hiroshima, take the Shinkansen (bullet train) to Fukuyama, then transfer to a local JR Sanyo Line train to Onomichi Station. The Hotel Cycle in the Onomichi U2 building, a popular starting point, is a short walk from the station. Alternatively, you can start from Imabari on Shikoku, which is also well-connected by train and bus. The route is clearly signposted with blue lines indicating the cycling path, making navigation straightforward. For those driving, parking is available at both ends of the route, but public transport is generally recommended for convenience.
A common complaint among some cyclists is the occasional lack of clear signage for detours or specific attractions, leading to minor confusion. To mitigate this, it's advisable to download an offline map or use a GPS-enabled cycling app. Another point of concern can be the limited food and drink options in certain stretches, especially on smaller islands; packing some provisions can prevent hunger pangs. Lastly, while the path is mostly flat, the ramps leading up to the bridges can be steep. Those concerned about physical exertion should opt for an electric-assist bike or plan for more frequent breaks.
