Ayabe Ohashi Bridge: A Graceful Steel Arch Across the Yura River
In the northern reaches of Kyoto Prefecture, a row of seven gentle steel arches stretches across the Yura River, linking the riverside neighbourhoods of Namimatsu-cho and Mikata-cho in the city of Ayabe. This is the Ayabe Ohashi Bridge, completed in 1929 and still in everyday use as a road bridge nearly a century later. Its silvery-blue trusses, set low against the water, form one of the most beloved landmarks of the "Sea of Kyoto" region. Recognised by the Japanese government as a Registered Tangible Cultural Property in 2005, the bridge offers visitors a rare and beautiful encounter with early Showa-era civil engineering, framed by the open river valley and the surrounding mountains.
From Ferry Crossings to a Modern Steel Bridge
Until the early Meiji period, there was no permanent bridge over the Yura River at Ayabe; people and goods crossed by ferry. A first wooden bridge appeared around 1876, and a more substantial wooden structure was completed in 1894, only to be swept away in the great flood of August 1896. A replacement built in 1898 met the same fate the following year. The Yura River, with its sudden floods, made wooden bridges a constant struggle.
In the late 1920s, despite the worldwide economic turmoil of the period, the town of Ayabe was prospering thanks to the silk industry. The textile company Gunze, founded here in 1896, had turned Ayabe into a celebrated "silk capital." It was against this backdrop of local prosperity that the present steel bridge was finally built and opened in 1929 (Showa 4), a confident statement of the town's ambitions for the modern age.
Why It Was Designated a Cultural Property
On 12 July 2005, the Ayabe Ohashi Bridge was added to the national Register of Tangible Cultural Properties as a structure of significant historical value. Several qualities set it apart.
First, it is a remarkably intact example of an early-Showa highway bridge built from steel. Spanning 210 metres in total, with seven spans of approximately 29 metres each and a deck width of 5.2 metres, it has continued to serve as an active road bridge for almost a century, requiring only periodic maintenance, including repairs in 1973.
Second, the structural form is increasingly rare. The bridge is described in official records as a low-rise pony-type seven-span steel curved-chord Warren truss with a reinforced-concrete deck slab. In more accessible terms, it is closely related to the bowstring truss, a prefabricated steel bridge type originally developed by the German firm Harkort and widely adopted in Japan from the late Meiji to early Showa periods. Most such bridges were replaced as vehicles grew larger; very few survive today, making Ayabe Ohashi an important reference for the history of Japanese bridge engineering. With its seven continuous spans, it is reportedly second in length among Japan's surviving multi-span bridges of this type, after the Abegawa Bridge in Shizuoka (1923, fourteen spans).
Third, the design intentionally echoed the form of the wooden bridge it replaced, preserving a sense of continuity with the older Yura River landscape. The work was carried out by Matsuo Steel Bridge Co., Ltd., a pioneering Osaka-based steel-bridge maker that is today part of IHI Infrastructure Systems.
Highlights and Things to See
The pleasure of Ayabe Ohashi lies in its understated, human-scaled beauty. Walking across the bridge is the best way to appreciate its character.
The Rhythm of Seven Arches
Seen from the riverbanks or from the neighbouring Tanba Ohashi Bridge, the seven curved upper chords march across the water in an even, almost musical rhythm. Their gentle rise gives the structure a softer silhouette than later, more massive truss bridges.
An Active Heritage Bridge
Unlike many cultural properties, this bridge is still part of daily life. It carries Kyoto Prefectural Road 450 with one-way traffic and a vehicle-height restriction of approximately two metres, while pedestrians and cyclists can cross freely. Walking the deck offers a quiet, slightly time-shifted experience of the river.
The View Up- and Downstream
From the centre of the span, the Yura River opens out in both directions. The mountains of northern Kyoto rise on the horizon, and on clear mornings a soft mist often lingers over the water. The riverside walk is also a fine spot to view the bridge from below, especially in cherry-blossom season and in autumn.
The "Blue Bridge" of Ayabe
Locally, Ayabe Ohashi is known affectionately as the "blue bridge" thanks to the colour of its painted steelwork. Together with the Peace Tower – erected to commemorate Ayabe's 1950 declaration as the world's first World Federation City – it is one of the visual symbols of the modern town.
Around the Bridge
Ayabe Ohashi sits within easy walking distance of several attractions that together make for a rewarding half-day or full-day visit.
- Ayabe Gunze Square: A heritage complex centred on the Gunze Museum, housed in repurposed Taisho-era cocoon storehouses. Exhibits trace the history of the silk-reeling and textile industries that shaped modern Ayabe.
- Ayabe Rose Garden: Within Gunze Square, this volunteer-managed garden showcases around 1,200 roses of more than 170 varieties, with rose festivals in late spring and autumn.
- Baishoen Garden (Oomoto Headquarters): The spiritual centre of the Oomoto religion, founded in Ayabe. The grounds include the Choseiden, said to be one of the largest wooden buildings of the twentieth century, and the Konohana-an, a nationally important cultural property.
- Shisuigaoka Park: A hilltop park offering one of the best panoramic views of the Yura River and the bridge, especially fine during cherry-blossom and autumn-leaf seasons.
- Ayabe City Museum: A compact local museum providing context for the city's history, from ancient times through the silk-industry era.
- Anokuji Temple: A short trip out of the centre brings you to this Rinzai-school temple, the principal Ankokuji of the country and traditionally associated with the birthplace of the shogun Ashikaga Takauji.
Visitor Information
Ayabe Ohashi is a publicly accessible road bridge, free to cross at any time of day. There is no entrance fee and no opening hours. Visitors are asked to be mindful of vehicle traffic on the bridge deck and to use the pedestrian space provided.
The bridge is about a 15-minute walk from JR Ayabe Station on the Sanin Main Line, which is served by limited-express trains from Kyoto, Fukuchiyama and Higashi-Maizuru. By car, it is reached from the Maizuru-Wakasa Expressway via the Ayabe IC. Parking is available near Ayabe Gunze Square and other nearby facilities; please follow local signage.

Q&A
- When was Ayabe Ohashi Bridge built and is it still in use?
- The bridge was completed in 1929 (Showa 4) and remains in active service today as a one-way road bridge on Kyoto Prefectural Road 450, while also welcoming pedestrians who wish to walk across.
- Why is this bridge considered a Registered Tangible Cultural Property?
- It was registered in 2005 because of its rarity as an early-Showa multi-span steel highway bridge of the curved-chord truss family, its excellent state of preservation, and its long continuous service connecting both banks of the Yura River.
- What kind of bridge is it, structurally?
- Official records describe it as a low-rise pony-type seven-span steel curved-chord Warren truss with a reinforced-concrete deck. It is structurally close to the bowstring-truss family, a once-common but now rare type in Japan.
- How do I get there from Kyoto City?
- Take a JR limited-express train from Kyoto Station to Ayabe Station; the journey takes about 75 to 90 minutes. From the station, the bridge is around a 15-minute walk to the east.
- Is photography allowed on and around the bridge?
- Yes, photography for personal and travel purposes is welcome. The riverbanks, nearby Tanba Ohashi Bridge and Shisuigaoka Park all offer attractive vantage points; please take care of traffic when photographing on the bridge itself.
