The Spectacular Landscape of Hashigui-iwa
A Natural Landscape Created by Powerful Geological Forces
Hashigui-iwa is a remarkable group of rock formations arranged in an almost straight line offshore between Kushimoto and Kii-Oshima Island. Their appearance resembles the wooden or stone pillars supporting a bridge, which is why they became known as “Hashigui-iwa,” meaning “bridge-pillar rocks.”
Some of the rock pillars rise approximately 15 meters above the surrounding area. The contrast between the rugged rocks and the deep blue waters of the Pacific Ocean creates an impressive landscape.
The scenery changes dramatically according to the tide. At high tide, seawater surrounds the rocks and can reflect their shapes like a mirror. At low tide, visitors can walk between some of the formations and see the rocks from a much closer perspective.
The landscape is particularly beautiful at sunrise. Hashigui-iwa is recognized as one of Japan’s notable sunrise viewing locations, and the sight of the morning sun rising over the Pacific and illuminating the rocks in golden light is unforgettable.
Sunset also offers a completely different atmosphere, as the rocks can take on warm reddish tones as the sun disappears over the horizon.
A Geologically Important Landscape
Hashigui-iwa is believed to have formed approximately 15 million years ago through volcanic activity. Magma rising from underground entered cracks in layers of rock. Over an extremely long period, waves gradually eroded the softer surrounding material, leaving behind the harder rock formations.
The resulting landscape is valuable not only for its beauty but also for its geological significance. Hashigui-iwa has been recognized as one of Japan’s important geological sites and is also one of the representative geosites of the Nanki-Kumano Geopark.
In this sense, the rock formations can be regarded as a natural work of art created by volcanic activity and millions of years of erosion.
The Legend of Kobo Daishi and the Mischievous Demon
Hashigui-iwa is also associated with a famous local legend involving Kobo Daishi Kukai, one of the most influential Buddhist figures in Japanese history.
According to the legend, Kobo Daishi once challenged a mischievous demon known as Ama-no-Jaku to see who could build a bridge between Kushimoto and Kii-Oshima in a single night.
Kobo Daishi began placing rocks one after another to construct the bridge. However, when Ama-no-Jaku realized that Kobo Daishi was about to win, he imitated the sound of a rooster crowing to make Kobo Daishi believe that dawn had arrived.
Thinking that morning had come, Kobo Daishi stopped working before the bridge was completed. The story says that only the pillars remained standing in the sea, creating the landscape now known as Hashigui-iwa.
This legend adds a fascinating cultural dimension to the unusual rocks and helps explain why the area has long been regarded as a mysterious and special place.
Facilities and Things to Enjoy
Viewing Area and Oceanfront Terrace
A viewing area on the second floor provides an excellent panorama of Hashigui-iwa. With few obstacles blocking the view, visitors can take in the dramatic combination of the Pacific Ocean and the rows of rock pillars.
The terrace features seating where visitors can relax while enjoying the sea breeze. On clear days, the blue sky and ocean create a particularly beautiful scene.
Local Products and Souvenirs
The roadside station’s shop sells a wide selection of specialty products from Kushimoto and the Kumano region, including sweets, seafood products, local foods, handicrafts, and agricultural products.
Wakayama’s famous ume products and products made with jabaram, a distinctive Japanese citrus fruit, are among the items visitors can discover.
Kushimoto also has a long history of friendship with Turkey, so visitors may sometimes find unique Turkish-themed souvenirs reflecting this cultural connection.
The shop is an excellent place to look for gifts and souvenirs that provide a taste of the southern Wakayama region.
Popular Ponkan Soft-Serve Ice Cream
One of the most popular treats at the fast-food corner is ponkan soft-serve ice cream, made with locally produced ponkan citrus.
The refreshing citrus aroma and pleasantly sweet flavor make it a favorite among visitors. Enjoying the soft-serve while looking out over Hashigui-iwa is a simple but memorable part of a visit.
Other casual foods and drinks, including yakisoba, French fries, and various snacks, are also available for travelers looking for a quick meal.
Hashigui Beach
Swimming with a Spectacular View
Next to Hashigui-iwa is Hashigui Beach, a beautiful beach that has been selected as one of Japan’s “100 Best Swimming Beaches” by the Ministry of the Environment.
The beach features clear water and sandy shores. From the beach, visitors can enjoy an exceptional panorama with Hashigui-iwa to one side, Kii-Oshima Island in front, and the Kushimoto Bridge on the other side.
The water is relatively shallow and the waves are generally calm, making the beach popular with families. Facilities such as showers, changing rooms, lockers, and shops are also available during the appropriate season.
Marine Activities
From spring through autumn, visitors can enjoy marine activities such as sea kayaking and stand-up paddleboarding (SUP).
Seeing Hashigui-iwa from the water offers a completely different perspective from viewing it from land. Gliding across the clear blue Pacific while approaching the rock formations is an exciting way to experience the area’s natural beauty.
Kushimoto’s Famous Usukawa Manju
A Traditional Sweet Inspired by Hashigui-iwa
One of Kushimoto’s best-known souvenirs is Usukawa Manju, a traditional Japanese confectionery associated with the town.
Its distinctive shape is said to evoke the appearance of Hashigui-iwa, making it an especially appropriate souvenir for visitors who have explored the famous rock formations.
The confectionery has been produced by Gihei, a traditional Japanese sweets shop founded in 1893. It features a very thin outer layer surrounding mildly sweet homemade bean paste.
A subtle sake-like aroma and elegant sweetness complement both Japanese tea and coffee. Each confection is carefully prepared by hand, reflecting the craftsmanship of traditional Japanese sweets.
Relax at Kobo-yu Hot Spring
Near Hashigui-iwa is a hot spring facility known as Kobo-yu. According to local tradition, Kobo Daishi is said to have introduced the villagers to the presence of the hot spring.
Today, the facility operates as a private hot spring accommodation that can be rented as a whole unit. The semi-open-air bath offers views of the sea, allowing guests to relax while feeling the ocean breeze.
Soaking in the hot spring while looking toward Kii-Oshima provides a peaceful way to unwind after sightseeing. The spring is classified as a simple sulfur spring and has traditionally been used for relaxation and recovery from fatigue.
Seasonal Beauty and Nighttime Scenery
Illuminations and Moonlit Views
Hashigui-iwa is also illuminated during special annual events. After dark, the illuminated rock formations emerge dramatically from the surrounding darkness, creating a magical atmosphere.
The area has been recognized as one of Japan’s important nighttime scenic destinations. On clear nights, the combination of the moon, sea, and rock formations creates an especially beautiful view. Hashigui-iwa is also recognized as a notable location for viewing the moon in Japan.
A Different Landscape in Every Season
Hashigui-iwa offers different scenery throughout the year. Spring and summer bring bright blue skies and vivid ocean colors, while autumn is ideal for enjoying clear air and beautiful sunsets. Winter creates a quieter and more solemn atmosphere along the coast.
The appearance of the rocks also changes depending on the weather, tide, time of day, and season. This constantly changing scenery is one reason why the area can be enjoyed repeatedly.
An Excellent Base for Exploring Kushimoto
Roadside Station Kushimoto Hashigui-iwa is much more than a simple rest stop. Its location makes it an important sightseeing base for exploring Kushimoto and the southern Kii Peninsula.
The tourist information area provides information about attractions in Kushimoto and the wider Kumano region, helping visitors plan their trips. Staff can also provide sightseeing guidance, making the facility convenient for first-time visitors.
Several major attractions are located nearby, including Cape Shiono-misaki, Kii-Oshima Island, and Kushimoto Marine Park. The roadside station is therefore an excellent stop for travelers exploring the region by car.
A Scenic Gateway to Southern Wakayama

Visitors can enjoy spectacular coastal scenery, beautiful sunrises and sunsets, fascinating geological formations, traditional legends, local food, souvenirs, beaches, marine activities, and hot springs.
