The Shimanami Kaido is, for many travelers, the single most beautiful cycling route in Asia. Stretching 70 km across six islands of the Seto Inland Sea, the path connects Onomichi in Hiroshima Prefecture to Imabari in Ehime Prefecture via a string of long, sweeping suspension and cable-stayed bridges. You will pedal between turquoise sea, fishing villages, citrus groves, and small towns where time moves at a different pace from Tokyo or Kyoto.
Best of all, the route is friendly to first-time cyclists and foreign visitors alike. The dedicated bike lane is paved, gently graded, and clearly marked with a blue line that you can follow without a map. Rental bicycles are available at multiple terminals, including a one-way option that lets you finish in either Onomichi or Imabari. You do not need to be a pro cyclist; even casual riders can comfortably split the route over two days with an overnight stop on one of the islands.
This complete guide is written for first-time foreign visitors to Japan. It covers everything: how to reach Onomichi or Imabari, where to rent a bike, what to pack, where to stay, what to eat, the best photo spots, and what to do if it rains. We will keep prices in both yen (¥) and US dollars to make planning easy, and finish with a detailed FAQ. Whether you have one day or three, you will leave with a clear, realistic plan.
What Is the Shimanami Kaido?
“Shimanami Kaido” (しまなみ海道) literally means “Island-Wave Sea Road.” Officially it is the Nishiseto Expressway, a 60 km motorway that opened in 1999 to connect Honshu (Japan’s main island) with Shikoku (the smallest of the four main islands). What makes the road extraordinary is that beneath every bridge runs a dedicated cycling and pedestrian path, allowing visitors to traverse the entire 70 km route by bicycle, foot, or scooter.
The route crosses six inhabited islands – Mukaishima, Innoshima, Ikuchijima, Omishima, Hakatajima, and Oshima – via seven major bridges. Each bridge is an engineering marvel in its own right. The Tatara Bridge, for example, is one of the longest cable-stayed bridges in the world; the Kurushima-Kaikyo Bridges form a continuous 4 km span that includes three bridges. Cycling them is unforgettable, and on a clear day you can see the deep blues of the Seto Inland Sea stretching in every direction.
Why Cycling the Shimanami Kaido Is Worth Your Time
Most foreign first-timers stick to Tokyo, Kyoto, and Osaka because those cities are easy to reach and packed with iconic sights. But after a week or two of crowded temples and queue-heavy ramen shops, the Shimanami Kaido offers a release valve: open horizons, salty sea air, and a kind of slow, friendly hospitality that you will not find in central Tokyo. It is also one of the best ways to feel rural Japan as a non-driver, since the only “transport” you need is a rented bike.
The Famous Blue Line
The route is so well-marked that you barely need to think. A continuous blue line painted on the road shows you the cycling route from start to finish. At every fork, signs list the remaining distance to your destination. Even if you do not speak a word of Japanese, you cannot get truly lost.
How to Get to Onomichi or Imabari
Most riders start in Onomichi (Hiroshima side) and finish in Imabari (Ehime side), or vice versa. The choice depends on the rest of your itinerary. Both ends are well-connected to Japan’s national rail network.
Reaching Onomichi (Hiroshima Side)
Onomichi sits on the Sanyo Shinkansen line. From Tokyo, take the Nozomi Shinkansen to Fukuyama Station (about 4 hours, ¥17,500 / US$118), then transfer to a JR Sanyo local train to Onomichi (15 minutes, ¥330). From Osaka, the same trip takes 90 minutes total. From Hiroshima, it is just 90 minutes by Kodama Shinkansen plus local train.
Onomichi itself is one of Japan’s most charming small towns – a hillside fishing port with cats that lounge in stone alleys and a temple walk that climbs above the harbor. Many visitors spend a night before or after their ride to enjoy the town. For more on this part of Hiroshima, see our Onomichi Travel Guide.
Reaching Imabari (Ehime Side)
Imabari is a port city on Shikoku’s north coast. From Tokyo, the easiest route is Tokyo to Okayama by Shinkansen (3.5 hours), then a 2.5-hour Limited Express Shiokaze train to Imabari (¥7,000 / US$47 with reservation). Total trip from Tokyo: about 6 hours. From Hiroshima, you can take a high-speed ferry directly to Imabari in 75 minutes (¥4,200 / US$28), which is the prettier option if you are coming from west Japan.
Many cyclists combine Shimanami Kaido with a wider Shikoku itinerary that includes Matsuyama, Dogo Onsen, or the 88 Temple Pilgrimage. For broader Shikoku planning, see our Destinations hub.
Combining with the JR Pass
If you have a JR Pass, both Onomichi and Imabari are well-covered. The Pass works on the Sanyo Shinkansen (Hikari and Sakura but not Nozomi), the JR Sanyo Line to Onomichi, and the Limited Express Shiokaze to Imabari. For a deeper look at whether the JR Pass is worth it for your trip, see our Japan Rail Pass Guide.
When Is the Best Time to Cycle Shimanami Kaido?
Spring (March-May): Cherry Blossoms and Mild Weather
Cherry blossoms typically peak in late March on the Shimanami Kaido. The combination of pink trees and turquoise sea is one of the best cherry blossom experiences in Japan. Daytime temperatures are 12-20°C (54-68°F), perfect for cycling. Book accommodations early; this is peak season.
Summer (June-August): Hot but Long Days
July and August are hot and humid, with daytime highs of 30-33°C (86-91°F). Rain is more common in the June rainy season. However, summer means long daylight hours and lush green islands. If you ride in summer, start early (before 8 AM), carry plenty of water, and consider a lighter half-day ride rather than the full 70 km.
Autumn (September-November): The Local Favorite
October and November bring crisp air, citrus harvests, and clear visibility for distant island views. Temperatures of 18-22°C (64-72°F) make this the most comfortable cycling weather of the year. The orange trees of Ikuchijima and Omishima ripen, perfumed citrus markets line roadside stalls, and the seas are calmer.
Winter (December-February): Quiet and Bright
Winter is underrated. Temperatures rarely drop below 5°C (41°F) and snow is extremely rare here. Days are shorter, but the air is sharp and the sky is often the clearest of any season, giving the most dramatic photos of the bridges. You will share the path with very few other cyclists. Pack warm layers, gloves, and a windbreaker.
How Long Does the Ride Take?
The full 70 km route takes between 5 and 8 hours of pedaling for an average rider, plus stops for food, photos, and rests. Most visitors choose one of three approaches:
Option 1: One-Day Full Ride (Confident Cyclists)
Start at Onomichi by 7:30 AM, finish in Imabari by 4-5 PM. Stops every 60-90 minutes for snacks, water, and bridge photos. This is the most physically demanding option and best suited to riders who comfortably handle a 50-70 km day at home.
Option 2: Two-Day Ride with Overnight (Most Popular)
Day 1: Onomichi to Ikuchijima or Omishima (around 35 km). Stop for the night at a guesthouse. Day 2: Continue to Imabari (around 35 km), arriving by mid-afternoon. This is the most popular pattern because it is comfortable, lets you enjoy the islands, and rewards you with a sunset and sunrise overlooking the sea.
Option 3: Half-Day Mini Loop (Casual Riders)
From Onomichi, take the ferry to Mukaishima (5 minutes), then ride to the Innoshima Bridge and back. Total: about 25 km, 3-4 hours. You see one of the seven bridges from above and below, plus a few small fishing villages. Perfect for travelers who want a taste without committing to the full route.
Where to Rent a Bike
You can rent in either Onomichi or Imabari, and one-way drop-off is supported between the two main terminals.
Onomichi U2 Cycling Hub
The hipster-friendly Onomichi U2 building, a converted seaside warehouse, houses the GIANT Store (premium road bikes from ¥7,000-¥12,000 / US$47-$80 per day) plus a hotel that lets you wheel your bike right into your room. Helmets, panniers, and repair kits are included.
Onomichi Port Rental Terminal
The municipal terminal at Onomichi Port offers basic city bikes and cross-bikes from ¥2,000-¥3,000 (US$13-$20) per day. One-way drop-off at any of the 13 official terminals along the route is allowed. This is the budget-friendly option for casual riders.
Sunrise Itoyama (Imabari Side)
The Sunrise Itoyama center at the Shikoku end of the Kurushima-Kaikyo Bridge offers similar rates to the Onomichi municipal terminal. Reserve in advance during cherry blossom and autumn peak weeks.
Tips for Booking
Reserve at least 7 days ahead during March-May and October-November. The Onomichi U2 GIANT Store accepts online English bookings; the municipal terminals can be reserved by email. Bring a credit card for the deposit. Note that most rental bikes are sized for Japanese riders; tall foreign visitors (180+ cm) should specifically request an L or XL frame at booking time.
The Seven Bridges: A Cyclist’s Perspective
Each bridge has its own personality. Here is a quick guide for what to look for as you cross.
1. Shin-Onomichi Bridge (Mukaishima)
Most cyclists skip this bridge entirely – the dedicated bike path runs from the Onomichi Port via a 5-minute ferry (¥110 / US$0.75 including bike). The ferry is part of the experience, not a workaround.
2. Innoshima Bridge (Mukaishima to Innoshima)
The first major bridge you cross by bike. Two-tier design, with cars on top and cyclists below, gives a unique caged-tunnel feel. From the bridge, you can see fishing fleets returning to harbor. Distance: 1.3 km.
3. Ikuchi Bridge (Innoshima to Ikuchijima)
An elegant cable-stayed bridge that opens up to one of the prettiest views of the route. Ikuchijima is famous for its lemon orchards, and you’ll likely smell the citrus before you see it.
4. Tatara Bridge (Ikuchijima to Omishima)
The architectural showstopper – one of the longest cable-stayed bridges in the world (1.5 km), with twin diamond-shaped towers. Stop at the rest area on the Ikuchijima side for the iconic photo.
5. Omishima Bridge (Omishima to Hakatajima)
The shortest bridge on the route (328 m), a sleek arch with views of Mt. Washigatoge. Many cyclists pause here for a snack or coffee at the small terminal area.
6. Hakata-Oshima Bridge (Hakatajima to Oshima)
Two bridges in series across a small islet, totaling about 1.5 km. The middle islet has a tiny park with views of the strong tidal currents – this is where the Seto Inland Sea narrows and the water visibly flows like a river.
7. Kurushima-Kaikyo Bridges (Oshima to Imabari)
The grand finale: three suspension bridges in a row, totaling 4 km, the longest continuous suspension bridge complex in the world. The view as you climb up to bridge level is genuinely breathtaking – a spider’s web of cables, the Seto Inland Sea below, and Imabari’s harbor in the distance. Save your camera battery for this section.
Where to Stay Along the Route
The biggest decision after picking your dates is where to spend the night. The two best options are Onomichi (start point) and one of the islands (mid-route). For the full two-day ride, an island overnight is what you came for.
Onomichi: Start or End
Onomichi has good hotel options for every budget, including the famous Hotel Cycle inside the Onomichi U2 cycling complex (cycle-friendly rooms with bike racks, US$140-$220). Cheaper guesthouses near the station start at US$70.

Ikuchijima: The Cultural Mid-Point
The town of Setoda on Ikuchijima has the largest concentration of mid-route guesthouses, plus the famous Kosanji Temple. Look for Yubune (a stylish hostel-bathhouse hybrid, US$100-$180), Azumi Setoda (luxury ryokan in a renovated merchant townhouse, US$400+), or basic guesthouses around US$50.
Omishima: The Quietest Option
Omishima is famous for the Oyamazumi Shrine, one of the most ancient in Japan, plus the Toyo Ito Architecture Museum. Stay at Tokoro Museum Omishima or one of the ryokan near the harbor for a quieter, more rural night.
Imabari: Finish Line City
Imabari is bigger than Onomichi but less charming. Most riders sleep here only on the night they finish. The Imabari Kokusai Hotel (mid-range, US$110) is the most reliable option near the station.

What to Eat Along the Route
The Seto Inland Sea region is famous for its seafood, citrus, and salt. Pacing yourself with three or four food stops is part of the joy of cycling Shimanami.
Onomichi Ramen
Before you start, fuel up with a bowl of Onomichi-style ramen – a soy-sauce based broth flavored with fish stock and topped with chunks of pork back fat. The most famous shop is Tsutafuji, near the harbor; expect a 30-minute lunch line. ¥800-¥1,000 (US$5-$7) per bowl.
Hassaku Daifuku (Innoshima)
A local sweet specialty: rice cake stuffed with sweet bean paste and a juicy slice of hassaku citrus. The shop Hassaku-ya in Innoshima is the most famous; many cyclists stop here as a mid-morning energy boost.
Setoda Lemon Specialties (Ikuchijima)
Ikuchijima produces 10% of Japan’s lemons. Try lemon gelato at Setoda Sunset Beach, lemon cake at Patisserie Okamoto, and lemon ramen at Chuka Soba Tsuru. Salt-lemon-tonic drinks at the cafes are also worth a stop on a hot day.
Imabari Yakitori Tetsupan
The Imabari area has a unique style of yakitori cooked on a hot iron griddle (tetsupan) rather than grilled over charcoal. The chicken comes out crispy on the outside and juicy inside. Imabari station has several yakitori joints within walking distance.
Imabari Tai Meshi (Sea Bream Rice)
Tai meshi is a specialty of the Imabari area: whole sea bream cooked in seasoned rice and served in a clay pot. A perfect celebratory dinner after finishing the route. Roughly ¥2,500-¥4,000 (US$17-$27) per person.

Practical Tips for First-Time Foreign Riders
- Helmet rentals are free. Always wear one; in Japan, head injuries are the most common cycling-related ER visit.
- Bring sunscreen and lip balm. The sun reflects off both the road and the sea; even a cool November day can leave you with sunburn.
- Pack a windbreaker. Temperatures on the bridges can be 5°C cooler than at sea level due to wind exposure.
- Carry small cash. Many island vending machines and small shops do not accept cards.
- Use the IC card system. Suica, Pasmo, ICOCA, and similar IC cards work on the JR trains and ferries that connect the route.
- Stay connected. Mobile data is essential for restaurant searches and Google Translate. Get your Japan eSIM (Stay connected from day 1) →
- Budget extra time at the bridges. You will want to stop every 1-2 km for photos.
- Watch for cars on island roads. While the dedicated path is car-free, sections on the islands themselves share roads with light traffic.
- Use the rest stops (michi-no-eki). Each island has at least one government-run “road station” with bathrooms, vending, and tourist info.
- Don’t push too hard. The ride is more enjoyable at a slow pace – this is not a Strava race.
How Much Does the Trip Cost?
For a complete two-day Shimanami Kaido trip from Tokyo, including transport, lodging, food, and bike rental, expect roughly:
- Backpacker (per person): ¥30,000-¥40,000 (US$200-$270) – JR Pass partially covering trains, hostel night, basic bike, conbini meals
- Mid-range (per person): ¥55,000-¥75,000 (US$370-$500) – Shinkansen reserved seats, mid-range guesthouse, cross bike, three meals at restaurants
- Comfort (per person): ¥110,000+ (US$740+) – GIANT premium road bike, luxury ryokan night at Azumi Setoda or Hotel Cycle, kaiseki dinner, return Shinkansen
For broader Japan budgeting, our Japan Budget Guide shows how to keep daily costs under US$50.

Detour Ideas: Side Trips from the Route
Kosanji Temple (Ikuchijima)
A spectacularly over-the-top temple complex modeled on Japan’s most famous shrines and temples. Combined with the Hill of Hope marble installation, it is one of the most surreal photo stops in the country. Allow 1-2 hours.
Hirayama Ikuo Museum of Art (Ikuchijima)
Dedicated to one of Japan’s most respected modern Buddhist painters, who was born on Ikuchijima. The museum’s collection is small but beautifully curated. Combine with the nearby Setoda Sunset Beach.
Omishima Architecture Walk
The Toyo Ito Museum of Architecture is on Omishima, plus the nearby Oyamazumi Shrine – one of Japan’s oldest Shinto shrines, with a treasure house of armor donated by samurai over centuries.
Murakami Pirate Museum (Oshima)
The Seto Inland Sea was once home to the Murakami pirate clan. The museum on Oshima has English signage explaining the pirates’ role in medieval Japan, plus armor and original documents.
Kurushima Strait Boat Tour
For a different perspective, take the Kurushima-Kaikyo Strait sightseeing boat from Imabari. The 50-minute tour passes under the suspension bridges and shows the powerful tidal currents up close. ¥1,800 (US$12).
Cycling Safety, Etiquette and Rules
Japan has a few specific rules that matter for foreign cyclists.
Riding Side
Japan rides on the LEFT, the same as the UK and Australia. Keep this in mind when joining the road; if you mistakenly drift to the right, you risk a collision with cars.
Helmets
While not legally mandatory for adults, all rental shops will provide free helmets and strongly encourage you to wear one. Children under 13 must wear a helmet by law.
No Smartphones While Riding
Holding a phone while cycling is illegal and risks a ¥5,000 fine. Mount a smartphone holder or stop at a rest area.
Lights at Night
If you ride after dark, you must have a front white light and a rear red reflector. Most rentals provide these.
Right of Way at Bridges
The bridge approach ramps spiral up gently to bridge level. Cyclists yield to faster road bikes when overtaking, and pedestrians always have priority.
What If It Rains?
Rain is uncommon outside the June rainy season, but if it does fall, you have options. The biggest is to take the local bus, which has a dedicated bike rack on the front. The Shimanami Liner bus runs between Onomichi and Imabari with a stop every island, and accepts 1-2 bikes per trip on the front rack. Tickets are around ¥2,500 (US$17) for the full route.
You can also pause your ride at one of the islands and visit indoor attractions like the Hirayama Ikuo Museum, Murakami Pirate Museum, or Toyo Ito Museum. Many guesthouses are flexible about late check-ins if rain delays you.
Photography on the Shimanami Kaido
Some of the best photo spots, in route order:
- Senkoji Park (Onomichi): Sunrise view over the city and the start of the bridges.
- Ikuchi Bridge approach: Sweeping view of Innoshima and the fishing fleet.
- Tatara Bridge rest area: The classic diamond-tower shot.
- Setoda Sunset Beach: The route’s namesake sunset, with bridges in silhouette.
- Hill of Hope at Kosanji Temple: Surreal white-marble installation.
- Kurushima-Kaikyo Bridge approach (Oshima side): Spider-web cable view.
- Imabari Castle moat: Reflective shot at the end of your ride.
Camera Gear Tips
Most riders use a phone, which is more than enough. If you bring a camera, a small pannier bag protects it from sea spray on windy bridges. A ND filter helps balance the bright sky against shaded ramp sections.
Combining with the Rest of Japan
Where Shimanami Kaido fits in a longer Japan trip depends on your direction.
Tokyo + Kyoto + Shimanami (10 days)
Tokyo (3 days), Kyoto (3 days), Hiroshima (1 day for Peace Park), Onomichi to Imabari (2 days), end with Matsuyama (1 day). Fly home from Matsuyama or take Shinkansen back to Tokyo via Okayama.
Western Japan Loop (10-14 days)
Osaka, Hiroshima, Onomichi, Shimanami Kaido, Matsuyama, Takamatsu, Naoshima, back to Osaka. Combines art islands, cycling, and major cities in a clean loop.
For Cyclists: A 7-Day Cycling Pilgrimage
Devote a full week to cycling-only travel: Hiroshima, Onomichi, Shimanami Kaido (3 days with overnights on Ikuchijima and Omishima), then continue across Shikoku to Tokushima or back via the Sazanami Cycling Course on Honshu’s south coast.
FAQ: Shimanami Kaido Cycling Questions Answered
How fit do I need to be?
If you can comfortably bike 20-30 km on flat terrain at home, you can ride Shimanami Kaido. The route is mostly flat, with gentle ramps onto each bridge (about 50 m elevation gain per ramp). Two days with an overnight is the easy pace; one day is more challenging.
Can I rent an e-bike?
Yes. Several shops including the Onomichi U2 GIANT Store rent e-bikes (electric assist) for ¥6,000-¥9,000 (US$40-$60) per day. E-bikes make the bridge ramps much easier and are popular with travelers in their 50s and 60s.
Is the route safe for children?
Yes for ages 10+. The dedicated bike path is fully separated from cars on the bridges. Children should wear helmets (legally required under 13). For families with younger kids, consider the half-day Onomichi-to-Innoshima loop instead.
Can I do it without speaking Japanese?
Yes. The blue line, English signage at major junctions, and friendly local staff make the route navigable without Japanese. Google Translate handles most menu and rental form questions. The bigger guesthouses on Ikuchijima have English-speaking staff.
Where can I leave my luggage?
Use the suitcase forwarding service “takkyubin” (Yamato Transport). Send your bag from your previous hotel directly to your Imabari (or Matsuyama) accommodation for ¥1,500-¥2,500 (US$10-$17) per piece. Allow 24 hours.
Are there ATMs along the route?
7-Eleven and Lawson convenience stores on the islands accept foreign cards. Imabari and Onomichi both have JP Post Bank ATMs near their main stations. The smaller islands have only a few ATMs total, so withdraw cash before you leave Onomichi.
Can I bring my own bike from home?
Yes, but it’s a hassle. Domestic bullet trains require bicycles to be packed in a specialized rinko bag. Most foreign visitors find it easier to rent locally and ship their gear separately if needed.
What’s the bike-friendly hotel called Hotel Cycle?
Hotel Cycle is the boutique hotel inside Onomichi U2 designed specifically for cyclists. Each room has a wall-mounted bike rack and tools available at the front desk. Rooms start around US$140 per night.
Is Wi-Fi available on the route?
Free Wi-Fi is available at every michi-no-eki rest area and most cafes. Cellular coverage is excellent on all six main islands. Mobile data is recommended for navigation and unexpected detours.
What if I need bike repairs?
Each rental terminal can do basic repairs. The Onomichi U2 GIANT Store has full mechanic service. If you have a flat far from any terminal, the rental contract covers a free pickup; call the number on the rental receipt.
Is the Shimanami Kaido suitable for solo travelers?
Excellent for solo travel. The path is busy enough on weekends and during peak seasons that you are never truly alone, but quiet enough that you have room for your own thoughts. Guesthouses are friendly to solo guests, and the food scene is welcoming.
How does Shimanami Kaido compare to other famous cycling routes in Japan?
It is widely considered the most beginner-friendly long-distance cycling route in Japan. Hokkaido’s routes are wilder and more remote; the Tohoku coast is more rugged; the Tobi-Shima Kaido on Hiroshima’s east coast is shorter but similar in style. Shimanami stands out for its bridge engineering and for being the only one ranked among the world’s top 10 cycling destinations.
Island-by-Island Deep Dive
The route is pretty even at a fast pace, but slowing down to explore each island is what turns a good ride into a great one. Here is a closer look at each of the six main islands, with a recommendation for at least one stop on each.
Mukaishima
The first island after the short ferry ride from Onomichi. Mukaishima is mostly residential, with quiet roads and a working harbor at its eastern end. Stop at the small flower park near the bridge, or pick up a coffee at a roadside stand before tackling the Innoshima Bridge climb. The local specialty here is octopus, often served as a quick takoyaki snack near the ferry terminal.
Innoshima
Famous for shipbuilding and for its medieval pirate history. The Innoshima Suigun Castle Museum tells the story of the Murakami clan, who controlled the Seto Inland Sea trade routes from the 14th to 17th centuries. There is also a small flower park (Innoshima Flower Center) and a citrus orchard area in the south. Hassaku-ya, the famous shop for citrus-stuffed daifuku, is just off the main route – well worth the small detour.
Ikuchijima
The cultural high point of the route. Setoda town is essentially built around Kosanji Temple, a Buddhist complex commissioned by a wealthy industrialist as a memorial for his mother. Each section of the temple complex copies a different famous Japanese building, but built at full scale. The Hill of Hope, an installation of 5,000 tons of white Italian marble, sits behind the temple and gives the most surreal view in the prefecture. Setoda’s small Showa-era streets are also great for wandering, with Setoda Sunset Beach providing the obvious sunset viewing point.
Omishima
Architecture lovers will not want to miss Omishima. The Toyo Ito Museum of Architecture features the work of the Pritzker Prize-winning architect, while the nearby Tokoro Museum and Iwata Hideo Memorial Museum focus on contemporary art. The Oyamazumi Shrine on the eastern side of the island is one of the most ancient in Japan and houses an extraordinary collection of samurai armor donated over more than a thousand years. Allow at least 2 hours if you are stopping at multiple sites.
Hakatajima
The smallest of the inhabited route islands, Hakatajima is most famous for its salt. The Hakata Salt Factory offers free tours and salt-tasting, and you can buy salt-flavored ice cream that is unexpectedly delicious on a hot day. The island has the smallest population on the route, giving it a particularly peaceful vibe.
Oshima
The last island before the spectacular finale at the Kurushima-Kaikyo Bridges. Oshima is known for its strong tides, which made it a natural pirate stronghold. The Murakami Pirate Museum here has English-language exhibits about the clan that ruled the Seto Inland Sea. There is also a small park overlooking the strait where you can see the tidal currents creating visible whirlpools at certain times of day.
Renting a Bike: A Step-by-Step Walkthrough
For most foreign first-timers, the bike rental process is the part that creates the most anxiety. Here is exactly what to expect.
Step 1: Reservations
Use the official Shimanami Cycle Oasis website (English version available) or the GIANT Store online form. Provide your dates, height, and which terminal you want to start at. Save the confirmation email; you will need to show it on arrival.
Step 2: Arrival at the Terminal
Onomichi Port rental terminal opens at 7:00 AM. Show your reservation, ID (passport for foreigners), and a credit card for the deposit (¥1,100 per bike, refunded on return). The staff fits you to a frame size, adjusts the seat, and shows you the basic gear changes. Allow 30 minutes for the entire process.
Step 3: Test Ride
Before you leave, take a short test ride around the parking lot to confirm seat height and check the brakes. If anything feels off, the staff will adjust without complaint. Better to take 5 minutes here than struggle for 50 km.
Step 4: Drop-Off
At your destination terminal, simply hand the bike to a staff member. They will inspect for damage and refund your deposit (sometimes by issuing a paper receipt to claim the refund at any official Lawson or 7-Eleven). Total drop-off time: 5 minutes.
Step 5: Lost Items and Late Returns
If you accidentally leave something on the bike, call the rental hotline within 24 hours and they will hold it. Late returns past 5 PM incur a small fee, but no penalty for delays caused by the included free pickup truck.
Bonus Side Routes Most Tourists Miss
If you have extra time and want to explore beyond the main blue line, consider one of these less-traveled spurs.
The Yume Shimanami Bay Loop
Add 6 km by detouring around the southern coast of Ikuchijima instead of going straight through Setoda. The road follows the coast, passing tiny fishing villages and quiet citrus terraces. Several small restaurants here serve fresh-caught fish at half the price of Onomichi.
The Mt. Kannogamine Climb (Ikuchijima)
For cyclists with extra energy, the climb up Mt. Kannogamine on Ikuchijima rewards you with a panoramic view of the entire route. About 6 km of climbing each way, with grades up to 8%. Best done as an early-morning side trip before continuing.
Imabari Castle Inner Moat Loop
Once you arrive at Imabari, ride the 2 km loop around the castle’s inner moat. The castle is one of the few in Japan built on the sea, with a moat that fills directly from the Seto Inland Sea, creating a unique tidal effect.
Tobishima Kaido (Continuation)
If you fall in love with island cycling, consider continuing on the lesser-known Tobishima Kaido after the Shimanami Kaido. Starting from Onomichi or Mihara, this 50 km route island-hops to Kawajiri on the Hiroshima coast and is even quieter than Shimanami. Bike-friendly buses connect the two routes.
Sustainability and Responsible Cycling
The Shimanami Kaido has become so popular that local authorities now publish guidelines for responsible visiting. A few key principles to follow.
Stay on Marked Routes
The blue line guides you on roads where cyclists are allowed. Some side trails on the islands are private property or unsafe; do not stray off marked paths.
Respect Quiet Hours
Island residents value their quiet evenings. Keep voices down at guesthouses, especially after 9 PM, and avoid loud music on the road during early mornings.
Carry Out Trash
Public trash cans are rare on the islands. Bring a small zip-top bag and carry your wrappers and used bottles to your guesthouse or the next michi-no-eki rest area.
Buy Local
The economic benefit of cycle tourism flows directly to small island businesses. A coffee at a roadside cafe, a citrus juice at a farm stand, or a souvenir from a Setoda glass studio is more meaningful than a similar purchase at a chain in the city.
Final Thoughts: The Best Slow Travel in Japan
Most Japan first-timers come for the cities, the food, and the cherry blossoms. The Shimanami Kaido offers something different: open horizons, sea air, and a chance to slow down enough that you actually notice the country around you. It is the rare experience where a foreign visitor can travel between two prefectures, cross seven engineering marvels, eat extraordinary local food, and never set foot in a tour bus.
If you have at least one full day to spare on your Japan trip, plan it for Shimanami Kaido. Book your bike rental, pack a windbreaker, and trust the blue line. The Seto Inland Sea is waiting.
