The Shimanami Kaido, a 70-kilometre cycling route unfurling across the Seto Inland Sea, connecting Honshu to Shikoku, stands as a jewel in Japan’s cycling crown. Far more than just a transit path, it is a meticulously crafted experience, immersing cyclists in a tapestry of coastal vistas, charming island communities, and engineering marvels. For those who view cycling not merely as means of locomotion but as a profound exploration, the Shimanami Kaido offers an unparalleled journey, a pedal-powered pilgrimage resonating with both the rhythm of the sea and the spirit of adventure.
Much like exploring cycling destinations across Asia and beyond, the Shimanami Kaido represents a travel-led cycling experience where the bike becomes the perfect tool for understanding terrain at human speed, rich in detail and cultural immersion.
A Monument to Modern Engineering
The concept of linking the main island of Honshu with the island of Shikoku across the often-treacherous Seto Inland Sea had long been a dream for regional development and improved transportation. The Shimanami Kaido, officially designated as National Route 317 (also known as the Nishiseto Expressway), is the culmination of decades of planning and engineering prowess, a testament to Japan’s ability to conquer geographical challenges.
Route Specifics:
- Total distance: 70 kilometres (43 miles) from Onomichi to Imabari
- Islands traversed: 6 islands (Mukaishima, Innoshima, Ikuchijima, Ōmishima, Hakatajima, Ōshima)
- Bridges crossed: 6 major bridges plus connecting spans
- Total elevation gain: Approximately 300 metres
- Average completion time: 4-6 hours for experienced cyclists, 6-8 hours leisurely
- Difficulty level: Moderate, suitable for most fitness levels
- Year opened: 1999
The sheer scale of the undertaking is staggering. Each bridge presents its own unique engineering challenge and visual splendour, from the elegant curves of the 1,480-metre Tatara Bridge (once the world’s longest cable-stayed bridge) to the robust triple suspension span of the Kurushima-Kaikyō Bridge.
The Strategic Route Design
Crucially, the Shimanami Kaido was conceived with cyclists in mind from its inception. The cycle path, painted in a distinctive blue stripe and marked with clear signage counting down kilometres to Imabari, is integrated into the bridge infrastructure, providing safe and scenic passage separate from motorised traffic. This foresight has transformed a functional transportation corridor into a world-renowned cycling destination, attracting over 300,000 riders annually.
The route’s planning acknowledges the diverse needs of cyclists, from those seeking a leisurely day trip to those embarking on multi-day expeditions. CNN named it one of the world’s seven best cycling routes, whilst Lonely Planet consistently ranks it amongst Asia’s top cycling experiences.
Setting Forth: Gateway to the Islands
Your journey along the Shimanami Kaido typically begins at Onomichi City on the Honshu mainland, a picturesque port town with rich history. This city serves as the ideal launchpad, offering necessary amenities and a tangible sense of stepping off the beaten path into the maritime embrace of the Seto Inland Sea.
Onomichi: A Cyclist’s Overture
Onomichi itself is a destination worthy of exploration. Known for its steep hills lined with 25 temples forming the Temple Walk, narrow alleyways, and a preserved retro shopping arcade, it offers a rewarding prelude to the main event. The town has served as a filming location for numerous Japanese films, lending it a nostalgic, cinematic quality.
Many cyclists choose to spend a night here, acclimatising to the change of pace and enjoying local cuisine. The city’s charm lies in its traditional architecture, the panoramic views offered from elevated vantage points like Senkō-ji Temple, and the thriving Cat Alley (Neko no Hosomichi), lined with cat-themed objects.
Key Onomichi Attractions:
- Senkō-ji Temple and park with ropeway access
- Temple Walk (25 historic temples)
- Retro shopping arcade
- Cat Alley
- Onomichi City Museum of Art (designed by Tadao Ando)
Starting Point: Onomichi U2 Complex
The modern starting point for most Shimanami Kaido cyclists is Onomichi U2, a brilliantly renovated warehouse complex positioned directly on the waterfront, just 5 minutes’ walk from JR Onomichi Station.
This purpose-built cycling hub features:
