Ehime Summer Guide: Shimanami, Dogo Onsen & the Sea
This summer Ehime guide links Shimanami island views, Dogo Onsen and the Iyonada coast, with heat tips and onsen etiquette.

Highlights

At a Glance

This two-day, one-night model course for summer in Ehime links the island scenery of the Shimanami Kaido, Dogo Onsen, and the coast of the Iyo Sea. You can savor sea and bridges, hot springs, and evening scenery in a single trip.

The Course Flow

It's easy to build a one-way route: bridges and sea at Imabari → island-hopping at Oshima → strolling the hot-spring town at Dogo Onsen → photos along the Iyo Sea coast the next day.

Estimated Travel Times

From Imabari to central Matsuyama is about 40–60 minutes by car, and from central Matsuyama toward Shimonada Station is about 40–50 minutes by car. Over two days and one night, you can cover each area without rushing.

Shimanami Kaido Highlights

From the 4,105-meter Kurushima Kaikyo Bridge (the world's first triple suspension bridge) connecting Imabari and Oshima, and the roughly 301-meter-high Kirosan Observatory Park, you can take in the bridges and the silhouettes of the Seto Inland Sea's islands at a glance.

How to Enjoy Dogo Onsen

A hot spring with about 3,000 years of history, said to be Japan's oldest. While admiring the architecture of the Dogo Onsen Main Building (a day-use public bathhouse and Important Cultural Property), you can also enjoy street food along the Dogo Shopping Street.

Iyo Sea Scenic Spots

Shimonada Station, an unstaffed station on the JR Yosan Line facing the sea, is a famous spot where you can photograph the station and the sea together. Futami Seaside Park is a sunset spot chosen among "Japan's 100 Best Sunsets," where you can savor the seaside afterglow.

Summer Preparation and Cautions

Prepare for the sun with breathable clothing, comfortable shoes, and a hat, and keep luggage light. At hot springs, wash before bathing and refrain from photographing the bathing area, and at stations and tracks, give priority to other users.

Plan an Ehime Summer Itinerary Connecting the Sea and Hot Springs

An Ehime summer itinerary feels easier and more enjoyable when you link the island scenery of the Shimanami Kaido, Matsuyama's Dogo Onsen, and the coastal scenery of the Iyo-nada Sea in a single continuous route.

When entering from the Imabari side, it is easy to build a route that lets you enjoy the sea and bridges first, add hot springs and a town walk in Matsuyama, and finally head toward the calm scenery of the Iyo-nada Sea.

As a guide, it takes roughly 40 to 60 minutes by car from Imabari to central Matsuyama, and roughly 40 to 50 minutes by car from central Matsuyama to the Shimonada Station area of the Iyo-nada Sea, so making it a 2-day, 1-night trip lets you tour each area without rushing.

Order Area How to Enjoy
Start Imabari Bridges and sea
Middle Island-hopping Scenic breaks
Evening onward Dogo Stroll the hot spring town
Next day Iyo-nada Coastal photos
Finish Around Matsuyama Food and shopping

Starting from Imabari Brings the Sea to the Forefront

The Shimanami Kaido makes it easy to experience the islands of the Seto Inland Sea and the chain of bridges, and placing it at the start of the trip conveys a sense of openness that feels distinctly Ehime.

Since there are moments when the summer sun feels strong, alternating time enjoying the outdoor scenery with time resting indoors lets you tour calmly.

Add Dogo Onsen and a Matsuyama Town Walk

Dogo Onsen is an easy place to rest your body after a seaside itinerary, and strolling in a yukata or snacking along the shopping street also fits easily into the flow of the trip.

Not cramming big plans in before or after bathing lets you enjoy the breathing room typical of a hot spring town.

The Iyo-nada Area Works Well as the Final Stop for Savoring the Trip's Afterglow

Coastal spots like Shimonada Station and Futami Seaside Park suit a way of spending time waiting for the changing colors of the sky and sea rather than rushing to see them.

It is reassuring to check the flow of returning to Matsuyama in advance according to your return transport and accommodation.

Tips for Enjoying Summer Island Scenery on the Shimanami Kaido

On the Shimanami Kaido, turning your attention not only to the experience of crossing the bridges but also to how the angle of the sea and the atmosphere of the villages change on each island makes the journey itself a highlight of the trip.

Choose a car, route bus, or bicycle based on the heat and the amount of luggage.

Grasp the Outline of the Trip from a Spot Overlooking the Kurushima-Kaikyo Bridge

On the Imabari side, stopping at an observation spot overlooking the Kurushima-Kaikyo Bridge lets you visually understand the scale of the sea and bridges you're about to cross.

The Kurushima-Kaikyo Bridge is a 4,105-meter bridge connecting Imabari City and Oshima, known as the world's first triple-suspension bridge with three suspension bridges linked together.

When taking photos with the bridge as a backdrop, stopping in a position that doesn't block the passage of pedestrians and cyclists makes it easier to avoid obstructing the flow around you.

Feel Both the Sea and the Mountains on Oshima

Even among the Shimanami Kaido islands, Oshima is an island where you can easily enjoy both the scenery of a hilltop overlooking the sea and the atmosphere of the calm coastal roads together.

Kirosan Observatory Park sits on a hilltop about 301 meters above sea level, and from the observatory designed by architect Kengo Kuma you can view the Kurushima-Kaikyo Bridge and the silhouettes of the Seto Inland Sea islands all at once.

On clear days you can sometimes see all the way to Mount Ishizuchi, the highest peak in western Japan, and in the evening the illumination of the Kurushima-Kaikyo Bridge and the night view of the Imabari cityscape are also highlights.


Think About Cycling in Short Sections First

The Shimanami Kaido is known as a mecca for cycling, and a blue line (the Blue Line) showing the recommended route is marked on the road surface, but in summer the burden of heat and slopes can feel considerable.

If you're on your first trip to Japan and not used to cycling, a realistic approach is to experience only part of a section rather than riding the whole thing and to cover the rest by public transport or car.

Plan Island Breaks Around Shade as Well as Sea Views

Since continuously taking photos uses up your energy, looking for places to sit and hydrate is just as important as looking for scenic spots.

By the sea, your body tends to hold heat even with a breeze, so prepare a hat and drinks early.


Recover from Summer Travel Fatigue at Dogo Onsen

Stopping at Dogo Onsen after feeling the sea breeze of the Shimanami Kaido creates the impression of your Ehime trip shifting from natural scenery to hot spring culture.

It is said to be Japan's oldest hot spring, with a history of about 3,000 years, and adding time to walk through the historic buildings and shopping street expands the enjoyment of a hot spring destination beyond just bathing.

Make the Building a Highlight at the Dogo Onsen Honkan

The Dogo Onsen Honkan (main building) is the symbol of Dogo Onsen, and in 1994 it became the first public bathhouse designated an Important Cultural Property of Japan.

Since the Honkan is a day-use public bathhouse where you cannot stay overnight, thinking of it as a place to enjoy a bath while viewing the exterior and interior design makes it easier to plan.

The preservation and repair work, which spanned about 6 years, was completed in December 2024, so you can now calmly take in the distinctive architectural beauty that has continued since the 1894 reconstruction.

Knowing Bathing Manners Helps You Use the Hot Spring with Peace of Mind

At Japanese hot springs, there are basics for using the facility pleasantly with others around you, such as refraining from taking photos in the changing room and bathing area and washing your body before entering the bath.

Being mindful of points such as avoiding bathing after drinking alcohol, locking your locker, and not putting your towel in the bath is also reassuring.


Lightly Combine Snacking and Shopping in the Hot Spring Town

Since your body warms up easily after bathing, centering your time on shopping and a light meal in the Dogo shopping street and avoiding hurried sightseeing makes it easier to spend your time.

Summer nights are a season when you'll want to go out, but checking the route back to your accommodation and the last transport service with the transport operator's information before you move is reassuring.


Leisurely Touring the Scenic Iyo-nada Coast

Unlike the bridge scenery of the Shimanami Kaido, the Iyo-nada coast is appealing for its quiet landscapes where the sea and sky open up widely.

In a summer itinerary, being mindful of the bright daytime sea, the soft evening light, and the temperature change heading into night lets you enjoy different expressions of the same sea.

Time How It Looks Best Way to Spend It
Morning Pale sea colors A walk
Daytime Blue sea surface Photo break
Evening Soft light Wait by the sea
After rain Wide sky Gaze at the station

Enjoy the Closeness of Station and Sea at Shimonada Station

Shimonada Station is an unstaffed station on the JR Shikoku Yosan Line, and since the scenery of the Iyo-nada Sea spreads out in front of the platform, it is known as a photo spot where you can easily capture the station building and the sea together.

It is a station that has been featured as the setting for Seishun 18 Ticket posters, films, dramas, and commercials, and it is also popular as a stop for the sightseeing train "Iyonada Monogatari."

Since the station is also a transport facility used in daily life, keep to safe positions on the platform and near the tracks, and take photos while giving priority to train users.


Leave Time by the Sea at Futami Seaside Park

Futami Seaside Park is a park in Futami-cho, Iyo City, attached to the "Michi-no-Eki Futami" roadside station, and suits a way of spending time viewing the Iyo-nada scenery from the sandy beach and around the deck.

Futami-cho is a sunset spot selected among the "100 Best Sunsets in Japan," where you can watch the setting sun from the stepped seawall known as the "sunset viewing seats," and it is also known as the first place in Ehime Prefecture certified as a "Lovers' Sanctuary."

In summer, the roadside station's farmers market and tenants may be listed as operating from 9 a.m. to 6 p.m., and since operating hours differ by shop and season, adjusting the time you combine shopping and rest lets you comfortably take your seaside time.

Don't Overpack Your Schedule When Aiming for the Sunset

Since the evening sea changes impression with the clouds and light, not planning to move on right after arriving and giving yourself a little room to wait raises your satisfaction.

When taking photos, not occupying the same spot for long and yielding the view to other travelers lets you spend your time pleasantly.

Summer Clothing, Items to Bring, and Travel Notes

On a summer trip in Ehime, while enjoying the coastal scenery, preparation that considers sunlight, sweat, luggage, and changes in body temperature after a bath is helpful.

Rather than special equipment, light preparation that makes it easy to move between outdoors and indoors supports the comfort of your trip.

Situation Good to Do Avoid
By the sea Use a hat Long direct sun
Before bathing Stay hydrated Bathing after drinking
When taking photos Clear the path Photos in the bath area
When traveling Keep luggage light Overpacking the schedule
Using stations Prioritize users Approaching the tracks

Choose Clothing That Handles Sweat and Sun Well

By the sea, you are easily exposed to the sun even on windy days, so having breathable clothing, comfortable walking shoes, and a sun-shading hat makes it easier to move around.

On days you'll use the hot spring, wearing clothes that are easy to take off and put on lets your preparation in the changing room go smoothly.

Keep Your Luggage to an Amount That Doesn't Hinder Photos and Travel

Since there are many moments you'll want to take photos on the Shimanami Kaido and at Shimonada Station, luggage that is too large makes it harder to move around.

If you carry a suitcase, checking the facilities at your accommodation or the station in advance and packing only what you need into a small bag makes it easier to move around.

Check Schedules and Operating Status for Transport

Since travel to coastal stations and toward the islands is easily affected by service frequency and connections, check the same-day timetable and operating information with the transport operator's guidance.

Shimonada Station has a limited number of trains, and if you use the Iyonada Monogatari, checking the boarding tickets, fare tickets, and meal reservation conditions in advance is reassuring.

Since the weather can also change in summer, planning alternative rest spots for outdoor-centered itineraries is reassuring.

Prepare to Communicate Even Without Multilingual Support

At rural stations and small shops, there are situations where English signage is limited, so saving destination names in Japanese script makes them easier to confirm.

Registering names such as "Dogo Onsen," "Imabari," "Shimonada Station," and "Futami Seaside Park" in a map app in advance makes it easier to avoid getting lost while traveling.

Arranging Your Ehime Summer Trip by Traveler Type

Even with the same itinerary, how you choose your detours changes depending on your fitness, interest in photography, and how you spend your time at the hot spring.

Since travel in Japan tends to lead to fatigue from the journey itself, an approach of deciding on one goal for your trip and leaving the rest as breathing room is a good fit.

If It's Your First Ehime Trip, Don't Dilute the Classic Route

If you're visiting Ehime for the first time, centering on the flow of the Shimanami Kaido, Dogo Onsen, and the Iyo-nada coast and not adding too many detours makes it easier to grasp the impression of the region.

Enjoying specialty dishes and shopping between travel, and leaving time to view the scenery at each place rather than adding more sightseeing spots, brings a sense of satisfaction.

If You Love Photography, Prioritize the Changing Light

If photography is your goal, combining places where the backdrop changes greatly, such as the Kurushima-Kaikyo Bridge, the exterior of the Dogo Onsen Honkan, the platform of Shimonada Station, and the Iyo-nada sunset, brings variety to your compositions.

When photographing people, adjust your angle so that others' faces don't appear too much in public places, and follow the photography rules inside hot spring facilities.

Summary | In Summer, Gently Connect Ehime's Sea and Hot Springs

An Ehime summer itinerary becomes an easy-to-understand trip even for a first visit to Japan when you create a route that lets you experience the Seto Inland Sea island scenery on the Shimanami Kaido, rest your body at Dogo Onsen, and savor the trip's afterglow along the Iyo-nada coast.

Combining the view of the Kurushima-Kaikyo Bridge, the architecture of the Dogo Onsen Honkan, and the sunsets at Shimonada Station and Futami Seaside Park lets you savor the appeal of both the sea and hot springs in a single trip.

Since fees, opening hours, transport connections, and how to use the hot springs may change, please check the information from the facilities and transport operators before departing.

By leaving room to avoid the heat and being mindful of photo manners, you can calmly enjoy time by the sea and in the hot springs that feels distinctly Ehime in summer.

Frequently Asked Questions

A. A one-way route linking the island scenery of the Shimanami Kaido, Matsuyama's Dogo Onsen, and the Iyo-nada coast is easy to follow. Start with the sea and bridges from Imabari, then enjoy hot springs and a town walk in Matsuyama, and finish with the seaside atmosphere along Iyo-nada. Making it a 2-day, 1-night trip lets you tour each area without rushing.
A. The Kurushima-Kaikyo Bridge is a 4,105-meter bridge connecting Imabari City and Oshima, the world's first triple suspension bridge with three suspension bridges joined together. The Kurushima Strait flowing beneath it is counted among Japan's three great rapids, and the swirling tidal currents are a highlight. The sight of ships passing one after another under the bridge is clearly visible from the viewpoint on the Imabari side.
A. From Kirosan Observatory Park, at about 301 meters above sea level, you can take in the Kurushima-Kaikyo Bridge and the island silhouettes of the Seto Inland Sea all at once. The observatory by architect Kengo Kuma is designed to be embedded in the ground and covered with trees, so it blends into the scenery so well its presence is hard to notice from outside. On a clear day you can even see Mt. Ishizuchi, the highest peak in western Japan.
A. From Imabari to central Matsuyama is roughly 40 to 60 minutes by car, and from central Matsuyama to the Shimonada Station area on Iyo-nada is roughly 40 to 50 minutes by car as a guide. Matsuyama to Imabari is also a smooth 40 minutes or so by JR limited express. Local lines have limited service, so allowing for traffic if driving, or transfer times if by rail, gives you some breathing room.
A. The recommended route is marked by a Blue Line painted on the road, which makes it easier for beginners to follow, but summer heat and slopes can still be demanding. Experiencing only part of the route rather than the whole route and covering the rest by car or route bus is realistic. It's handy to remember there are rental-cycle bases in front of Imabari Station and at Itoyama, and one-way drop-off is available too.
A. The Kami-no-Yu at Dogo Onsen Honkan is 700 yen for adults and 350 yen for children, and morning bathing is part of the local culture, with use available from 6 a.m. until around 11 p.m. It's a hot spring with about 3,000 years of history, said to be Japan's oldest, and in 1994 it became the first public bathhouse designated a national Important Cultural Property. After about six years of preservation work was completed in December 2024, visitors can calmly admire the architectural beauty of the 1894 building.
A. The basics are to wash your body before entering the tub, not put your towel in the water, and refrain from photography in the changing and bathing rooms. Tie back long hair and avoid bathing after drinking alcohol. In Japanese public baths, bathers generally use shared facilities in the nude, and it's safest to lock valuables in a locker rather than bring them into the bathing area. It's also reassuring to learn the practice of pouring water over yourself to get used to the temperature before entering.
A. Shimonada Station is an unstaffed station on the JR Yosan Line, about an hour by local train from Matsuyama Station. However, there are only about nine stops a day in each direction, so checking the timetable in advance is essential. It's a famous photo spot with Iyo-nada spreading right in front of the platform, but it's an active station used daily. Give priority to train passengers and shoot from a safe position without approaching the tracks.
