How to enjoy

Choose how to enjoy your visit

Eat, shop, play, take in the view or rest. Choose from the station’s strengths to suit your day.

First things on arrival
Check the specialty shop and restaurant hours

The shop, restaurant and hot spring keep different hours. Families may find it easier to plan toilet and meal stops first.

If you are eating
Consider oysters and seafood

Aioi oysters are a winter highlight. Offerings change with the season and deliveries, so check official notices if you have a particular dish in mind.

If you are shopping
Processed oysters, grilled conger eel, local vegetables and seasonal fruit

Some items, such as Yano melons, have short selling seasons. Come early if you hope to find them before they sell out.

On a rainy day
Focus on food, the hot spring and indoor displays

Even when walking outside is difficult, a hot spring visit can make the detour worthwhile.

When the weather suits a walk
Stroll along the bay to Port Park

A little time outdoors turns a roadside stop into a visit to the port town.

For a half-day outing
Visit the seafood market or Manyo Cape

For more seafood, head to the market; for views, continue along National Route 250 to Manyo Cape.

Highlights

Aioi Peiron Castle is a gateway to a detour around Aioi Bay as well as a rest stop on National Route 250. Browse Aioi oysters and produce from western Harima in the specialty shop, choose a seafood meal at the Japanese restaurant, then rest at the second-floor Peiron hot spring with a view of the bay. With children, plan a toilet and meal stop first; if the weather allows, add a short outing to Port Park or Central Park. On rainy days, the hot spring, food and Peiron culture display still offer ways to spend time here. Peiron refers to Aioi's traditional boat races.

Why I like it

Reasons to stop here

01

Food and shopping bring you close to this port town

Aioi oysters, grilled conger eel, ikanago no kugini (small sand lance simmered in sweet soy sauce), and Yano melons reflect the seasons of Aioi Bay and western Harima. Beyond a seafood meal, choosing souvenirs to take home makes this a rewarding stop in Aioi.

02

A hot spring keeps a rainy-day visit flexible

The second-floor Peiron hot spring lists hours from midday into the evening on weekdays, and from morning into the evening on weekends and public holidays. It has an open-air bath, sauna and medicinal bath, so a meal and a soak can help reset plans in bad weather or during a long drive.

03

See Peiron culture in the building and bay

The name Hakuryujo (White Dragon Castle) and Chinese-style exterior evoke Aioi's Peiron boat-racing culture. Port Park is within walking distance; the Aioi Peiron Kaikan and seafood market are a little farther away. A walk along the bay reveals more of the town beyond the station.

Route idea

Ways to plan your stop

Spend your time at the station or add somewhere nearby. These ideas help you plan around your companions and the weather.

A coastal drive toward Himeji or Ako

Turn a Route 250 break into a meal beside Aioi Bay

A brief rest is possible, but oysters, other seafood, the specialty shop and bay views connect here. If arriving at lunchtime, decide whether to eat at the restaurant or buy food from the shop for the car.

On National Route 250; also convenient to include from the Sanyo Expressway's Tatsuno-nishi Interchange.

The restaurant and hot spring are often closed on Tuesdays, so check opening notices when planning a meal or bath.

Families with preschoolers; rainy-day detours

With children, plan food and toilets before going outdoors

This is not a station with large play equipment. Instead, food, toilets, a hot spring and tourist information are in one building. For children who need to move, add a short visit to Central Park across the national route or Port Park beside the bay.

Meal and toilet stop at Hakuryujo → Central Park or Port Park, weather permitting.

Wind and sun affect walks beside the water. With infants, leave time to return indoors.

Adult trips, long drives and rainy days

A hot spring can refresh the journey home

The Peiron hot spring is listed as open into the evening, making it useful after visiting Ako or Murotsu. Adding a bath can round off a short trip when a meal alone feels too brief.

Nearby sightseeing → meal at Hakuryujo → Peiron hot spring.

A fee change was announced for July 15, 2026. Follow the current fees posted on site.

Elementary school children and older; visitors seeking local culture

Learn about Peiron culture before walking beside the bay

Aioi's Peiron tradition extends beyond festival days. See the Hakuryujo display and tourist information, then continue to Port Park or Aioi Peiron Kaikan to connect the bay, boats and festival.

Hakuryujo → Port Park → Aioi Peiron Kaikan.

Aioi Peiron Kaikan's opening conditions vary by closure day and season; check ahead if you intend to tour or try an experience.

A weekend combining food and views

Winter oysters, then Manyo Cape on a clear day

In winter, Aioi oysters are prominent enough to make a visit to the seafood market appealing as well as the shop and restaurant. In good weather, follow National Route 250 onward to Manyo Cape. Sea and island views make Hakuryujo a starting point for an Aioi drive.

Hakuryujo → Aioi Municipal Seafood Market / Manyo Cape.

Seasonal goods such as oysters and Yano melons may arrive and finish within a short period.

Age one and under
★★★☆☆

Food, toilets and a rest can be combined indoors; keep waterside walks short according to the wind and sun.

★★★☆☆

Elementary school age
★★★★☆

Peiron culture, the harbor, fish market and Manyo Cape add opportunities to learn alongside a meal.

Do not make play equipment the main purpose

This station has no large playground; combine it with Central Park or Port Park for active time.

Use the hot spring on rainy days

Even without outdoor play, food and a bath make a worthwhile visit.

Reasons to return

Practical ideas and things to consider when spending time here.

Food mood

What would you like to eat?

A meal, a sweet treat, market shopping or something to take away: choose a focus for the day instead of trying everything at once.

Sit down for a full meal

Japanese dining Maneki / oyster dishes / seafood dishes

A leading choice if lunch is your reason for stopping. During the winter oyster season, a meal alone can justify the visit.

Expect possible crowds at lunchtime and on weekends. Check the Tuesday closure and last-order time.

Buy food to take home

Processed Aioi oysters / grilled conger eel / ikanago no kugini / local vegetables

Even without a restaurant meal, you can take a taste of Aioi with you. Start at the shop for port-town souvenirs.

Fresh fish and seasonal goods may become scarce later in the day.

Shop for the season

Aioi oysters / Yano melons

Winter oysters and early-summer Yano melons change the selection for a short season.

Official notices announce first and final deliveries, so check the latest information for anything specific.

Go further for seafood

Aioi Municipal Seafood Market, Toretore Market

If you want more than the station's selection, the seafood market offers another taste of Aioi Bay. Eating there is also an option.

Listed as closed on Wednesdays and the first Tuesday. Its closures differ from Hakuryujo's; check both when visiting on the same day.

Plan a light meal after bathing

Food after the hot spring / takeaway goods from the shop

If bathing in the evening, eat and shop first or plan backward from closing times.

The specialty shop is listed as closing at 17:30. Only the hot spring stays open into the night.
