Wakanoura

A Bay Where Tides and Poetry Have Met for Thirteen Centuries

Wakanoura sits at the mouth of the Waka River on the coast of Wakayama City, where a broad tidal flat opens between low pine-covered hills and the sea of Wakaura Bay. Twice a day the water draws back to expose a shining expanse of mud where herons and cranes feed, then fills again until the flats disappear. That rhythm is the reason this stretch of shore has been written about, painted, and visited for more than 1,300 years.

In 2010 the Agency for Cultural Affairs designated roughly 895,000 square meters of this landscape a national Place of Scenic Beauty (meishō), with an additional area added in 2014. The designation covers not only the tidal flat and the sandspit of Kataonami but a string of hills, shrines, a pagoda, and three historic bridges and pavilions that generations of visitors built to look out over the water.

The Emperor Who Renamed the Shore

The first record of Wakanoura comes from the tenth month of 724 (Jinki 1). Emperor Shōmu, then twenty-three and newly enthroned, traveled to the bay and was struck by what he saw from the hilltop of Tenguyama. According to the Shoku Nihongi, he ordered guards posted to protect the scenery, commanded that the spirits of the place be honored, and changed the old name of the shore to Akanoura, "the bay of bright light."

Among those who accompanied him was Yamabe no Akahito, one of the great poets of the age. His verse on the bay survives in volume six of the Man'yōshū, Japan's oldest poetry collection:

When the tide comes flooding into Waka Bay and the mudflats vanish, the cranes go crying toward the reedy shore.

The poem's phrase for the vanished mudflat, kata o nami, is said to have given the nearby sandspit its name, Kataonami. After Akahito, poets treated Tamatsushima and Wakanoura as utamakura, place-names charged with poetic meaning that writers invoked for centuries without needing to visit.

Tamatsushima itself refers to six small rocky hills, including Imoseyama, Kagamiyama, and Tenguyama. In Akahito's day the sea reached further inland and these rises stood among the water like beads strung on a cord, which is how they came to be called the "jeweled islands."

Why Wakanoura Was Designated

The national listing recognizes Wakanoura under three of the criteria used for scenic designations: viewpoints, bridges and embankments, and coastal landforms such as sandspits and beaches. Few designated landscapes combine all three so compactly.

What sets the bay apart is the layering of nature and human work across time. The tidal flat and the Kataonami sandspit are natural features praised since the eighth century. Around and above them stand structures added by later eras: a shrine to the deity of poetry, a pagoda raised by a feudal lord for his mother, and bridges built so that ordinary people could walk out and watch the tide turn. The cultural affairs evaluation described the result as a coastal landscape worthy of being called sacred ground, where the beauty of buildings from ancient through modern times is set against shifting water, green pines, and rock.

In 2017 the wider area was also recognized as a Japan Heritage site under the title "Wakanoura, Treasury of Fine Views."

What to See

Tamatsushima Shrine

At the foot of the hills stands Tamatsushima Shrine, the spiritual center of the bay. It enshrines Sotōrihime, honored as a deity of waka poetry, and is counted among the "three shrines of waka" together with Sumiyoshi Taisha in Osaka and the Kakinomoto Shrine in Akashi. From the Heian period onward, courtiers and poets came here to dedicate verse. During the Edo period several emperors and retired emperors sent poems written in their own hand to be offered at the shrine. Stone monuments inscribed with Akahito's poems stand in and near the precincts.

Imoseyama, the Pagoda, and the Stone Bridge

Imoseyama is a small rocky island in the tidal flat reached by Sandanbashi, a stone bridge built in the seventeenth century. On the island, Lady Oman, mother of the first Kishū lord Tokugawa Yorinobu, buried more than 150,000 small stones each inscribed with the title of the Lotus Sutra, an act of memorial around the thirty-third anniversary of Tokugawa Ieyasu's death. In 1655 (Meireki 1) Yorinobu raised the Kaizen-in pagoda over them in his mother's memory. A two-storied tahōtō on an island in a tidal flat is an unusual sight in Japan.

Kankaikaku Pavilion

Beside Imoseyama, Yorinobu also built Kankaikaku, a pavilion set out over the water on posts in the kakezukuri style. From here visitors could look across the bay toward the temple of Kimiidera and watch the tide and the moon. The pavilion fell into disrepair, and a wooden reconstruction matching its Edo-period form was completed in 2024, so visitors today can again stand over the flats much as people did four centuries ago.

Furōbashi, the Bridge of Carved Clouds

Furōbashi is a single-arched stone bridge built in 1851 (Kaei 4) along the processional road used by the Tokugawa house during the Wakamatsuri festival. The arch was the work of stonemasons brought from Higo, in present-day Kumamoto, and the stone balustrade carries reliefs of drifting clouds. Seen from the neighboring Ashibebashi with the slope of Tenguyama behind it, the low curve of the bridge is one of the most photographed views in the bay. The bridge is a Wakayama City designated cultural property, and after more than 160 years it is no longer crossed, so it is admired from the bank.

The Tidal Flat and Kataonami

The flat itself remains the main event. At low tide the mud stretches wide and feeding birds gather; at high tide the reeds along the edge stand in water. Kataonami, the sandspit named from Akahito's poem, is now a park with a pine-lined walking path of about 280 meters known as the Lane of the Man'yō, and a small museum, the Man'yōkan, that explains the poetry tied to the bay.

Around Wakanoura

The hill of Saikayama above the bay holds Kishū Tōshōgū, founded in 1621 by Tokugawa Yorinobu to honor his father Ieyasu. Reached by a straight flight of 108 stone steps called the Samurai-zaka, its lacquered gate and richly colored buildings have earned it the nickname "the Nikkō of western Japan." Seven of its structures are designated Important Cultural Properties, and its carvings are attributed to the workshop of Hidari Jingorō with wall paintings linked to Kanō Tan'yū. The annual Wakamatsuri festival in May, begun by Yorinobu, sends a portable shrine and a long costumed procession down the steps.

Nearby on the hillside is Wakaura Tenmangū, dedicated to Sugawara no Michizane, the deity of learning, with its own designated buildings and wide views over the bay from the top of its stone stairway. Walking between Tamatsushima Shrine, the Tōshōgū, and the Tenmangū makes a natural half-day route, with the tidal flat and Furōbashi in between.
