Onomichi and the Shimanami Kaido: Your Complete Day-Trip Guide from Hiroshima

The coastal town of Onomichi and the spectacular Shimanami Kaido cycling route offer one of Japan's most rewarding day trips from Hiroshima. This hillside port town, with its temple-lined slopes and retro shopping arcades, serves as the gateway to a 70-kilometre island-hopping route across the Seto Inland Sea. Whether you're a keen cyclist, a temple enthusiast, or simply seeking stunning coastal views, this journey delivers an authentic slice of Japanese coastal culture.

Getting to Onomichi from Hiroshima

Onomichi sits just 90 minutes east of Hiroshima City, making it perfectly positioned for a day trip or overnight stay. The JR Sanyo Line runs frequently from Hiroshima Station to Onomichi Station, with departures every 20-30 minutes throughout the day. The rapid service costs ¥1,520 one way and takes approximately 90 minutes, whilst local trains take slightly longer at around two hours.

If you hold a JR Pass, all trains on this route are fully covered, making the journey essentially free. Without a pass, consider purchasing a return ticket at Hiroshima Station to save a few minutes when departing Onomichi. Trains fill up during weekends and holidays, particularly in spring and autumn, so aim to travel mid-morning rather than joining the 8-9am commuter rush.

Oonomichi Station itself is compact and easy to navigate. As you exit, you'll immediately spot the shopping arcade stretching ahead and the temple-covered hillside rising to your left. The tourist information centre sits just outside the station and stocks English maps, cycling route guides, and accommodation lists.

Exploring Onomichi's Temple Walk

Oonomichi's defining feature is its Senkoji Temple Walk, a 2.5-kilometre path winding uphill through 25 Buddhist temples. The route takes roughly two to three hours to complete at a leisurely pace, though you can easily spend longer if you're photographing the atmospheric stone steps and centuries-old structures.

Start your walk at Jikoji Temple, a five-minute stroll from the station through the shopping arcade. The temple dates back to 1189 and features a distinctive three-storey pagoda visible from much of the town. From here, follow the stone-marked path upwards, passing through Saikokuji Temple with its ornate main hall, and Senkoji Temple at the hilltop, which offers panoramic views across the Seto Inland Sea and the islands beyond.

The walking route isn't particularly strenuous, but it does involve continuous climbing. Wear comfortable shoes with good grip, as the ancient stone steps can be slippery after rain. Early morning visits offer the best light for photography and fewer crowds, whilst late afternoon provides that golden-hour glow across the temple roofs and sea beyond.

If the walk feels too demanding, the Senkoji Ropeway whisks you from near the station to the summit in three minutes for ¥500 return (¥320 one way). Many visitors ride up and walk down, which puts less strain on the knees and lets you enjoy the temple architecture without the uphill effort.

Onomichi's Charming Shopping Arcades

The covered Onomichi Hondori Shopping Arcade stretches for 1.3 kilometres through the town centre, lined with independent shops that have traded here for decades. This isn't a tourist-focused arcade filled with souvenir shops; instead, you'll find traditional tofu makers, old-fashioned sweet shops, and family-run restaurants serving local specialities.

Look out for Onomichi ramen shops along the arcade. This regional style features a rich soy-based broth topped with generous amounts of pork back fat, creating an intensely flavourful bowl that's quite different from Hiroshima's more famous tsukemen. Restaurants like Tsutsui and Shuka serve excellent versions for around ¥800-900 per bowl.

The arcade also houses several retro coffee shops, locally called "pure kissa", where time appears to have stopped around 1975. These establishments serve thick-cut toast, strong filter coffee, and cream sodas in the original glass tumblers. Cafe Yutaka, midway through the arcade, is particularly atmospheric with its wooden counters and vintage radio collection.

Introduction to the Shimanami Kaido

The Shimanami Kaido is a 70-kilometre cycling route connecting Onomichi to Imabari on Shikoku Island, hopping across six islands via a series of suspension bridges. Opened in 1999, this dedicated cycling path has gained international recognition as one of the world's most scenic bike routes, offering constantly changing views of the Seto Inland Sea, small fishing villages, and citrus groves.

You don't need to cycle the entire route to enjoy the experience. Many visitors cycle to the first or second island and return, which provides a satisfying half-day ride whilst still experiencing the route's highlights. The first 15 kilometres to Innoshima Island makes an excellent introduction, offering stunning bridge crossings without requiring advanced fitness levels.

Bicycle Rental and Practical Cycling Information

Several rental shops operate near Onomichi Station, with the most convenient being Onomichi Port Rent-a-Cycle Terminal, located five minutes' walk from the station towards the waterfront. They stock various bike types including city bikes (¥1,000 per day), cross bikes (¥1,500), road bikes (¥3,000), and electric-assist bikes (¥2,000).

Electric-assist bikes make excellent sense for most visitors, as they eliminate the effort required for the bridge approaches whilst still providing exercise and that sense of achievement. The battery range covers around 60-70 kilometres, more than sufficient for a day's riding. Reserve ahead during peak seasons (April-May and October-November) by emailing or calling the day before.

The rental system operates across multiple islands, allowing one-way rides where you drop the bike at a different terminal. However, for day-trippers from Hiroshima, returning to Onomichi makes more practical sense given train schedules. The route features clear blue-line markings throughout, making navigation straightforward even without GPS.

Rental shops provide basic helmets, locks, and route maps at no extra charge. Bring water and snacks from Onomichi's convenience stores, as options become limited once you're on the islands. The bridges themselves have no facilities whatsoever.

Cycling to Mukaishima and Innoshima

The first bridge, crossing to Mukaishima Island, rises gradually from Onomichi's waterfront. The cycling path separates completely from vehicle traffic, running alongside the road but protected by barriers. As you climb, views open up across Onomichi's packed hillside houses and temple roofs, providing excellent photo opportunities about halfway across.

Mukaishima Island itself is quiet and residential. The cycling route passes through small neighbourhoods where you might spot elderly residents tending vegetable patches or hanging laundry, offering glimpses of everyday island life. The entire island crossing takes roughly 20 minutes at a comfortable pace.

Innoshima Island, the second stop, deserves more time. The island produces citrus fruits including hassaku oranges and lemons, with groves visible from the cycling path. Stop at Innoshima Suigun Castle, a 1983 reconstruction of a medieval fortress that houses a museum about the Murakami Suigun pirates who controlled these waters during the 16th century. Admission costs ¥330 and takes about 30 minutes to explore.

The return journey from Innoshima to Onomichi covers approximately 30 kilometres total, taking around two to three hours including stops. This leaves enough time to catch an early evening train back to Hiroshima, arriving around 7-8pm depending on your train choice.

Best Times to Visit

Spring and autumn offer ideal conditions for cycling the Shimanami Kaido. April brings cherry blossoms to temple grounds and roadsides, whilst October and November deliver comfortable temperatures and crystal-clear skies. Summer (June through August) can be brutally hot and humid, with temperatures regularly exceeding 32°C and little shade on the bridges. Bring substantial sunscreen, a hat, and extra water if visiting during summer months.

Winter (December through February) sees fewer tourists and sharp, clear days perfect for photography. However, strong winds occasionally close the cycling paths on exposed bridge sections, and some smaller cafes and facilities keep reduced hours. Check weather forecasts before setting out, as rain makes the painted bridge surfaces quite slippery.

Weekdays offer quieter experiences than weekends, particularly on the cycling route where rental bikes can sell out on sunny Saturdays and Sundays. Temple areas remain peaceful even during busy periods, as most cyclists head straight for the bridges without exploring Onomichi's hillside paths.

Where to Eat in Onomichi

Beyond the previously mentioned ramen shops, Onomichi offers several local specialities worth seeking out. The town sits along major sea bream fishing grounds, so restaurants serve exceptional tai-meshi (sea bream rice) for around ¥1,200-1,500. Onomichi-ya, a 10-minute walk from the station, serves particularly good versions alongside fresh sashimi sets.

For lunch near the cycling route, Shimanami Shokudo on Mukaishima Island serves home-style teishoku sets featuring local fish, rice, miso soup, and pickles for ¥900-1,200. They open at 11am and close around 3pm or when ingredients run out, so arrive before 1pm during weekends.

The Onomichi Shotengai (shopping arcade) hosts several standing bars and small izakaya that open from early evening. These offer local craft beers from Onomichi Brewery and small plates of grilled fish, perfect for a quick bite before catching your train back to Hiroshima.

Combining with Hiroshima Sightseeing

If you're staying multiple days in Hiroshima, dedicate one full day to Onomichi and the Shimanami Kaido rather than trying to squeeze it alongside Peace Memorial Park and Miyajima. The journey and cycling require time, and rushing diminishes the experience significantly.

Alternatively, consider staying overnight in Onomichi, which transforms beautifully after day-trippers depart. The town has several guesthouses and small hotels, with particular character found in renovated merchant houses along the temple walk. Prices start around ¥5,000 per person for basic accommodation, rising to ¥12,000-15,000 for more atmospheric traditional inns.

An overnight stay lets you tackle more of the Shimanami Kaido route, potentially reaching Setoda on Ikuchijima Island where Kosanji Temple's gaudy, fascinating grounds mix Buddhist statuary with Italian marble and Renaissance-style paintings. The complete experience takes a full day, making it impractical for day-trippers but perfect for overnight visitors.

Essential Practical Tips

Bring yen cash, as many small shops and rental outlets in Onomichi and on the islands don't accept credit cards. ATMs at the 7-Eleven near Onomichi Station accept international cards if you need to withdraw additional funds.

Public toilets appear regularly along the cycling route, typically at the base of each bridge and in small parks. They're generally clean and well-maintained, though don't expect heated seats or bidets at these rural facilities.

Mobile phone coverage remains strong throughout the route. Download offline maps before setting out regardless, as battery life can drain quickly when using GPS continuously during multi-hour rides.

Bridge tolls apply to cars but not bicycles or pedestrians, meaning your cycling journey incurs no additional fees beyond initial bike rental. This represents excellent value compared to many European and North American cycling routes that charge access fees.

The Shimanami Kaido stays open 24 hours, but cycling at night isn't recommended. The route lacks lighting, and while reflective markers guide the way, it's simply not safe. Plan to finish cycling by sunset at the very latest.

Making the Most of Your Visit

Start early from Hiroshima, aiming for the 8am or 9am train to maximise daylight hours in Onomichi. This schedule gives you time for both temple walking and a good cycling stretch before needing to return. The 5pm or 6pm trains back to Hiroshima provide comfortable margins for bike returns and dinner.

Don't feel pressured to cycle enormous distances. The first 15-20 kilometres deliver the essential Shimanami Kaido experience, and pushing further when you're tired or running short on time just creates stress. Remember that you need energy for the return journey too.

Combine cycling with cultural exploration rather than treating this purely as a sporting challenge. The temples, small islands, and coastal atmosphere form the real appeal here, not merely clocking up kilometres. Take time to stop, explore side paths, chat with locals at small shops, and soak up the peaceful Seto Inland Sea environment that makes this region so special.

Oonomichi and the Shimanami Kaido showcase a gentler, more traditional side of western Japan, far removed from Hiroshima's urban energy or Miyajima's tourist crowds. This journey rewards slow, mindful travel, offering memories that extend well beyond simple sightseeing.
