Bike Touring Japan: Shimanami Kaido Cycling Guide

The Shimanami Kaido is a 70-kilometer cycling route that connects Onomichi in Hiroshima Prefecture to Imabari in Ehime Prefecture, crossing six islands in Japan’s Seto Inland Sea via a series of soaring suspension bridges. For more, see our guide to Japan outdoor adventure guide. It is widely regarded as the best cycling route in Japan and one of the finest in the world — a designation that cycling organizations, travel publications, and the thousands of riders who complete it each year unanimously support.

What makes the Shimanami Kaido extraordinary is the combination of world-class cycling infrastructure, stunning island scenery, rich cultural stops, and the effortless hospitality that Japan delivers better than anywhere else. The route is accessible to casual riders on rental bikes and rewarding for seasoned touring cyclists, making it one of the most versatile cycling destinations on the planet.

A 2026 travel roundup by EF Adventures recently named e-biking the Shimanami Kaido as one of the world’s most unforgettable experiences — and for good reason.

Route Overview

The Shimanami Kaido (formally the Nishiseto Expressway) is a 60-kilometer expressway with a dedicated cycling and pedestrian path that runs alongside the vehicle lanes on each of the six bridges, with separate cycling routes across each island. The total cycling distance is approximately 70–80 kilometers depending on your route choices on the islands.

The Six Islands

The route crosses these islands in order from Onomichi (north) to Imabari (south):

1. Mukaishima — A short ferry ride from Onomichi brings you to this first island. Flat riding through residential areas and citrus groves.

2. Innoshima — Known for its history as a base for medieval pirates (suigun). The Innoshima Suigun Castle and the island’s flower garden are popular stops.

3. Ikuchijima — Home to the Kosanji Temple, a remarkably ornate Buddhist temple complex, and the Hirayama Ikuo Museum of Art. This island also produces some of Japan’s finest citrus fruits.

4. Omishima — The cultural heart of the route. The Oyamazumi Shrine houses the largest collection of samurai armor and weaponry in Japan. The island has a relaxed, timeless quality.

5. Hakatajima — The smallest island on the route. Known for its salt production and the Hakata Salt Factory, where you can sample salt-flavored ice cream (surprisingly good).

6. Oshima — The last island before Imabari. The Yoshiumi Rose Garden and the stunning Kurushima-Kaikyo Bridge viewpoint are highlights. The Kurushima-Kaikyo Bridge is the world’s longest suspension bridge system.

The Bridges

The six bridges are engineering marvels and visual highlights of the ride. Each has a dedicated cycling lane accessed by long, gently graded ramps (typically 3% gradient) that spiral up from island level to the bridge deck. The climbs are moderate and manageable even for casual riders.

Key note for 2026: Cycling tolls on the Shimanami Kaido bridges are currently waived as a temporary measure to promote tourism. This free-toll policy has been extended through at least March 31, 2026 — check before your trip to see if it continues.

Planning Your Ride

One Day or Two?

Most cyclists complete the Shimanami Kaido in one or two days:

One day (for fit riders): Start early (7–8 AM), ride the full 70 km, and arrive in Imabari by mid-afternoon. This pace allows brief stops at viewpoints and one or two cultural sites, but you will be riding most of the day. Average speed of 15–20 km/h including stops.

Two days (recommended): Split the route overnight on one of the middle islands (Ikuchijima or Omishima are the best options). This pace lets you explore temples, museums, beaches, and local restaurants without rushing. You can detour to scenic coastal roads, swim at island beaches, and genuinely absorb the experience.

Three days (leisurely): For those who want to explore every island thoroughly, three days allows time for side trips, longer meals, and spontaneous discoveries. This is the best option if cycling is a means of travel rather than the primary activity.

Which Direction?

Most cyclists ride from Onomichi to Imabari (north to south). This direction has slightly better signage, puts the prevailing wind at your back (usually), and finishes at the more logistically convenient endpoint for onward travel. However, the route works perfectly well in either direction.

Getting There

To Onomichi (Northern Start)

From Tokyo: Take the Shinkansen (bullet train) to Fukuyama Station (approximately 3 hours 30 minutes), then transfer to a local JR Sanyo Line train to Onomichi (20 minutes). Total journey: about 4 hours.

From Osaka: Shinkansen to Fukuyama (1 hour 15 minutes), then local train to Onomichi. Total: about 1 hour 45 minutes.

From Hiroshima: JR Sanyo Line direct to Onomichi (approximately 1 hour 30 minutes) or Shinkansen to Mihara then local train (faster).

To Imabari (Southern Start)

From Tokyo: Shinkansen to Okayama, transfer to JR Shiokaze limited express to Imabari. Total: about 5 hours.

From Matsuyama: JR Yosan Line limited express to Imabari (35 minutes).

Returning

If you ride one-way, return options include:

• Bus: Highway buses connect Imabari and Onomichi (approximately 1 hour 30 minutes). Bikes can be transported in bags.
• Ferry: Several ferry services cross the Inland Sea between the two endpoints.
• Train: JR trains connect both cities via Fukuyama and Okayama (2–3 hours with transfers).

Bike Rental

The Shimanami Kaido has two well-established bike rental systems:

Public Rental System (Shimanami Japan)

The primary rental network operated by the local government with approximately ten terminals along the route. This system allows one-way rentals — pick up at Onomichi and drop off at Imabari (or any terminal in between).

Bikes available: City bikes, cross bikes, tandems, e-bikes Cost: Approximately ¥1,100–3,300 per day depending on bike type ($8–22 USD), plus a ¥1,100 deposit (refunded if you return the bike to the same terminal; forfeited for one-way rentals) E-bike rental: ¥2,200–3,300 per day — highly recommended for casual riders, older travelers, or anyone who wants to climb the bridge ramps effortlessly

How to rent: Reserve online through the Shimanami Japan website or walk up to a terminal. Reservations are recommended during peak seasons (spring cherry blossom season, Golden Week, autumn).

Giant Store Rental

The Taiwanese bicycle manufacturer Giant operates two rental terminals — one in Onomichi and one in Imabari — offering higher-end road bikes and cross bikes.

Bikes available: Giant road bikes, cross bikes, e-bikes Cost: ¥4,400–11,000 per day ($30–75 USD) Advantage: Better-quality bikes with proper fit adjustment, helmet included, and optional accessories (bags, locks, lights)

Bringing Your Own Bike

If you are touring Japan with your own bicycle, the Shimanami Kaido is fully accessible. Bike parking and basic maintenance (pumps, tools) are available at most terminals. Bike shops in Onomichi and Imabari can handle repairs.

For cyclists considering a broader bike touring adventure across Japan, the Shimanami Kaido makes an excellent segment within a larger itinerary. Our bikepacking routes guide covers planning fundamentals for multi-day rides.

Where to Stay

Onomichi

A charming hillside port town with narrow lanes, temples, and excellent restaurants. Worth arriving a day early to explore.

• Budget: Guest houses and hostels from ¥3,000/night ($20 USD)
• Mid-range: Ryokan (traditional Japanese inns) from ¥8,000/night ($55 USD)
• Splurge: The ONOMICHI U2 is a converted waterfront warehouse with a hotel, restaurant, and Giant bike shop — purpose-built for cycling tourism

On the Islands

Accommodation options on the islands include:

• Guesthouses and minshuku: Simple, family-run accommodations from ¥4,000/night. These offer the most authentic cultural experience, often including home-cooked dinners featuring local seafood.
• Ryokan: Traditional inns with tatami rooms, futon bedding, and multi-course kaiseki dinners. From ¥10,000/night on Omishima and Ikuchijima.
• Camping: Campgrounds on several islands offer tent sites from ¥500/night. Ikuchijima’s Setoda Sunset Beach has oceanfront camping.
• Cyclist-specific lodging: Several accommodations cater specifically to cyclists, with bike storage, repair tools, and laundry facilities. The Shimanami Kaido has embraced cycling tourism more fully than almost any destination in the world.

Imabari

A mid-sized city with good hotel options near the station.

• Budget: Business hotels from ¥5,000/night ($35 USD)
• Mid-range: The Imabari Kokusai Hotel offers comfortable rooms with onsen (hot spring bath)

What to See and Do Along the Route

Cultural Highlights

Kosanji Temple (Ikuchijima): An elaborate Buddhist temple complex built in the early 20th century by a wealthy businessman in honor of his mother. The Hill of Hope marble garden at the rear offers sweeping views of the Inland Sea.

Oyamazumi Shrine (Omishima): One of Japan’s oldest and most important Shinto shrines, housing a collection of samurai armor that is designated as a national treasure. The camphor trees in the shrine grounds are over 2,600 years old.

Innoshima Suigun Castle (Innoshima): A reconstruction of a medieval pirate fortress. The Murakami pirates controlled these waters for centuries, levying tolls on passing ships — a historical echo of the bridges you are cycling across.

Natural Beauty

Tatara Bridge Viewpoint: The view from the Omishima side of the Tatara Bridge is one of the most photographed cycling scenes in Japan. The bridge sweeps across the strait with islands dotting the blue water in every direction.

Sunset Beach (Ikuchijima): A palm-lined beach with westward exposure that delivers spectacular sunsets over the Inland Sea. This is the best overnight stop if you are splitting the ride across two days.

Citrus Groves: The islands of the Inland Sea produce some of Japan’s best mikan (mandarin oranges), lemons, and hassaku. In season (October through February), roadside stands sell fresh fruit for a few hundred yen. Fresh-squeezed citrus juice is available at several stops along the route.

Food

The Shimanami Kaido is a cycling route that doubles as a culinary trail:

• Onomichi ramen: A regional specialty featuring a soy-based broth with a layer of pork back fat. Several shops near the station have been perfecting their recipes for decades.
• Takomeshi (octopus rice): A specialty of the islands, where freshly caught octopus is cooked with seasoned rice.
• Jakoten (fish cake): An Imabari specialty — whole small fish ground and deep-fried into savory cakes.
• Salt ice cream: Hakatajima’s famous salted vanilla ice cream at the Hakata Salt Factory is a mandatory stop.
• Fresh seafood: Every island has small restaurants serving fish caught that morning from the Inland Sea.

Practical Tips

Navigation

The route is marked with a blue line painted on the road surface that guides you from bridge to bridge across each island. Following the blue line is almost foolproof, though it occasionally fades in places. Supplement with a downloaded map or GPS track for the island sections where you might want to detour from the main route. Touring cyclists who want onboard navigation should look at our best GPS watches for adventure travel roundup — several models store multi-day routes and track elevation across long cycling days.

Each bridge approach ramp is well-signposted in Japanese and English. You will not get lost on the bridges themselves — there is literally only one path.

Weather and Season

Spring (March–May): Cherry blossom season (late March to mid-April) is magical but crowded. Temperatures are mild (15–22°C). This is peak season for the route.

Summer (June–August): Hot and humid (30–35°C). The rainy season (tsuyu) typically runs from mid-June to mid-July. If you ride in summer, start very early to avoid afternoon heat.

Autumn (September–November): Excellent riding weather. Temperatures cool, crowds thin after October, and autumn colors appear in late November. The citrus harvest begins.

Winter (December–February): Cool but rideable (5–12°C). Very few tourists. Some rental terminals may have reduced hours or inventory.

Physical Difficulty

The Shimanami Kaido is accessible to any reasonably fit person. The island roads are mostly flat with gentle rolling hills, and the bridge approach ramps are designed for cycling with gradual gradients (3% or less). The total elevation gain across the full route is approximately 500 meters — spread across 70 km, this is gentle.

The main physical challenge is simply the distance. At 70 km, first-time cyclists may find the second half tiring, especially with headwind. An e-bike rental eliminates this concern entirely and is worth the modest extra cost for casual riders.

What to Carry

• Water: At least one bottle. Convenience stores (conbini) and vending machines are available on every island — Japan’s vending machine density means you are never far from hydration.
• Cash: Many small restaurants, guesthouses, and some ferry services are cash-only. ATMs are available in Onomichi and Imabari but rare on smaller islands. Carry ¥10,000–15,000 in cash.
• Rain jacket: Weather can change quickly over the Inland Sea. A packable rain jacket weighs almost nothing and prevents a miserable ride.
• Sunscreen and hat: Sun exposure on the bridges is significant — no shade for long stretches.
• Camera: The scenery demands it. For waterproof options, see our best waterproof cameras guide.
• Lock: If renting, most rental bikes come with a built-in wheel lock. If bringing your own bike, carry a light cable lock for stops at temples and restaurants.

Combining with Broader Japan Travel

The Shimanami Kaido fits naturally into a broader Japan adventure itinerary:

Hiroshima (1–2 days): Visit the Peace Memorial Park and Museum, explore Miyajima Island (famous for its floating torii gate), and try Hiroshima-style okonomiyaki.

Matsuyama (1–2 days): Accessible from Imabari by train (35 minutes). Visit Matsuyama Castle and soak in Dogo Onsen, one of Japan’s oldest and most famous hot spring bathhouses.

Naoshima Art Island (1 day): A ferry ride from the Inland Sea area brings you to this island filled with contemporary art museums (Chichu Art Museum, Benesse House) and outdoor installations.

Shikoku 88 Temple Pilgrimage: For the truly adventurous, the 1,200-km pilgrimage route around Shikoku Island passes through Imabari. Cycling segments of this ancient route is an increasingly popular alternative to walking.

E-Bike vs. Regular Bike

The availability of e-bike rentals on the Shimanami Kaido has democratized the route. Consider an e-bike if:

• You are not a regular cyclist
• You want to ride the full distance in one day without exhaustion
• You plan to explore detour routes that add hills
• You are traveling with riders of different fitness levels
• You want to arrive at cultural stops with energy to actually enjoy them

Regular bikes are better if:

• You are a confident cyclist who enjoys the physical challenge
• You want the purest cycling experience
• You are on a tight budget (regular bikes are cheaper to rent)

There is no stigma attached to e-bikes on the Shimanami Kaido — a significant percentage of riders use them, including many Japanese cyclists.

Budget Breakdown

A two-day Shimanami Kaido cycling trip costs approximately:

Expense	Budget	Mid-Range
Bike rental (2 days)	¥2,200–4,400	¥8,800–16,500 (Giant)
Accommodation (1 night)	¥3,000–5,000	¥8,000–15,000
Food (2 days)	¥3,000–5,000	¥6,000–10,000
Bridge tolls	¥0 (free through 2026)	¥0
Ferry (Onomichi to Mukaishima)	¥120	¥120
Return transport	¥2,000–3,500	¥2,000–3,500
Total	¥10,320–18,020 ($70–120)	¥24,920–45,120 ($170–305)

This makes the Shimanami Kaido one of the most affordable world-class cycling experiences available — another reason it consistently ranks among the best cycling routes globally.

Final Thoughts

The Shimanami Kaido delivers something rare in adventure travel: a world-class experience that is genuinely accessible to everyone. You do not need to be an athlete, an experienced cyclist, or even particularly brave. You need a rented bicycle, a day or two of time, and the willingness to pedal across one of the most beautiful landscapes in Japan.

The route gives you everything — engineering marvels, ancient shrines, island beaches, extraordinary food, and the simple joy of moving through a landscape under your own power. It is the kind of trip that converts non-cyclists into cycling enthusiasts and makes seasoned riders fall in love with Japan.

Rent a bike. Follow the blue line. Stop for ramen. The Seto Inland Sea is waiting.
