The Chikugo River Lift Bridge is a historic movable railway bridge that once formed part of the Saga Line operated by Japanese National Railways. It connects Okawa City in Fukuoka Prefecture with Morodomi, Saga City, in Saga Prefecture. After the railway line was discontinued, the bridge was preserved and converted into a pedestrian walkway.
Known in its former railway role as the Chikugo River Bridge, it is recognized as an Important Cultural Property of Japan and a Mechanical Heritage site. Its distinctive central section rises and falls vertically to allow ships to pass along the river, making it Japan’s oldest surviving bridge of this type.
The Chikugo River Lift Bridge was completed in 1935, the 10th year of the Showa era, and opened on May 25 of that year. It was built as a railway bridge designed to accommodate river traffic as well as trains. By allowing the central section to rise vertically, the bridge enabled ships to pass through while maintaining a railway connection between the two riverbanks.
The bridge is 507.2 meters long. Its movable section measures 24.2 meters, and the vertical lifting distance is 23 meters. At the time of its construction, it was referred to as the “Orient’s greatest movable railway bridge,” reflecting the scale and technical ambition of the engineering project.
Railway engineer Iwao Kugimiya played a central role in the bridge’s design, while the lifting mechanism itself was devised by Tane-yoshi Sakamoto. When a ship needs to pass, the movable section rises vertically between the supporting towers, providing clearance for river traffic.
The bridge’s engineering attracted attention beyond Japan. A detailed model of the structure was exhibited at the 1937 Paris World’s Fair, demonstrating the technical sophistication of the project.
The Saga Line was discontinued in 1987, and the bridge was closed along with the railway. It faced the possibility of demolition, but strong requests from the local community helped secure its preservation.
In 1992, the bridge was transferred free of charge from the Japanese National Railways Settlement Corporation to Okawa City. Following restoration work, it reopened on April 29, 1996, as a pedestrian-only promenade. The bridge once again became a link between Okawa City in Fukuoka Prefecture and Morodomi in Saga City, while also becoming a symbolic landmark for both communities.
Parks have been developed at both ends of the bridge. Railway equipment from its operating days, including signals and warning devices, has also been preserved, allowing visitors to see traces of its former role in railway transport.
The bridge was registered as a Tangible Cultural Property of Japan in 1996 and designated an Important Cultural Property in 2003. In 2007, it was recognized as Mechanical Heritage No. 23 by the Japan Society of Mechanical Engineers. These designations recognize both its historical significance and the ingenuity of its movable structure.
Repair and preservation work continues periodically to protect the bridge and pass its historical and technological value on to future generations.
Today, the Chikugo River Lift Bridge is used as a pedestrian bridge and can be crossed free of charge. A donation box is installed near the center of the bridge, and contributions help cover maintenance costs.
On clear days, visitors can enjoy a leisurely walk while taking in views of the Chikugo River and its broad waterside landscape. Parks and parking areas at both ends make the bridge a convenient stop for families, sightseers, and travelers exploring the surrounding region.
Visitors may walk their bicycles across the bridge, but riding a bicycle over it is prohibited. Pets are also not permitted on the bridge, so visitors should take this into account when planning their visit.
Since 2012, the bridge has been illuminated after sunset. The lights reflected on the surface of the Chikugo River create an atmospheric nighttime view, giving the historic structure a different appearance from the one it has during the day.
The surrounding area also hosts seasonal events that provide opportunities to experience local culture and the natural environment. The bridge’s combination of industrial heritage and riverside scenery makes it an appealing destination throughout the year.
The Chikugo River Lift Bridge has attracted attention as a filming location because of its distinctive structure, scenic setting, and historical background. In 2003, it was used for a commercial for the Oita barley shochu brand Nikaido. The bridge’s striking appearance and the surrounding river scenery helped make the location memorable to viewers.
The bridge has also been used as a location for films and television dramas, bringing attention to the region and its historic landscape.
The former route of the Japanese National Railways Saga Line has been developed into the Jofu Cycling Road, allowing visitors to explore the area by bicycle. The cycling route offers a way to discover the landscape associated with the old railway line.
Although cyclists cannot ride across the Chikugo River Lift Bridge itself, they can dismount and push their bicycles across on foot. This makes it possible to combine a cycling trip with a walk over one of Japan’s most distinctive historic railway structures.
From Nishitetsu Yanagawa Station on the Tenjin Omuta Line, take a Nishitetsu Bus bound for Saga Station via Okawa and Morodomi. Get off at the Okawa Bridge bus stop, turn left at the Okawa Bridge intersection, and continue straight to reach the lift bridge.
From JR Saga Station on the Nagasaki Main Line, take a Saga City Bus on the Morodomi–Hayatsue route and get off at the Shokaibashi-mae bus stop. Nishitetsu Bus services on the same route can also be used.
By car, visitors can approach from the Kyushu Expressway via the Yame Interchange and travel west along National Route 442. Another route is from the Nagasaki Expressway via the Higashi-Sefuri Interchange, continuing south along National Route 385.
Only a small number of movable railway bridges remain in Japan, and the Chikugo River Lift Bridge is especially significant among them. Its ability to raise the central span reflects the engineering needs of an era when railways and river transport had to coexist along the same route.
Visitors can appreciate the bridge not only as a historic structure but also as a peaceful place to walk beside the river, enjoy the illuminated scenery, and learn about the area’s industrial heritage. A visit offers a distinctive combination of engineering history, riverside views, and a connection between the communities of Fukuoka and Saga.
