Ushibuka Haiya Ohashi is an 883m long, 13.6m wide bridge spanning Ushibuka Bay in Amakusa, Kumamoto. It is one of the longest and most significant bridges in the prefecture, designed not merely as a transport link but as a piece of architectural art that integrates with the landscape. The design team includes world-famous architect Renzo Piano, structural engineer Peter Rice, and Kenmei Okabe. The concept, "a single line floating on the sea," results in a minimalist, smooth curve that blends perfectly into the natural environment.
Built under the 'Kumamoto Art Polis' project, the bridge's name, 'Haiya,' is derived from the traditional local folk song, 'Ushibuka Haiya Bushi.' Completed after construction between 1991 and 1997, it has become a symbol of the region. The bridge's exceptional design has earned numerous accolades, including the Tanaka Prize from the Japan Society of Civil Engineers, representing a successful fusion of infrastructure, local culture, and art.

The most striking feature is its unique '7-span continuous steel plate girder' structure. The design separates the roadway from the pedestrian and cycling paths by height, allowing visitors to stroll while looking down at the ocean. The minimalist design, which embodies the concept of a 'single line,' creates a breathtaking sight against the blue sky and sea. Additionally, the bridge features a structural loop that connects to Shimoda Island via a branching intersection.
During the day, the sharp contrast between the white bridge and the blue ocean clearly illustrates the intended 'floating line' aesthetic. At sunset, the silhouette of the bridge becomes particularly striking against the changing colors of the sky, offering a different mood than the bright daylight hours. It is a perfect spot to enjoy the shifting light of Amakusa's natural beauty.
To truly experience the design intent, we recommend using the dedicated pedestrian and cycling paths. Since these are separated from the vehicle lanes, you can enjoy the scenery safely. Nearby, you can visit 'Michi-no-Eki Ushibuka Kaisakan' to enjoy local delicacies and regional specialties alongside the bridge's view. Even just driving across the bridge and viewing the curves through your car window is a unique way to enjoy the area.
The area surrounding the bridge offers the rich natural beauty of Amakusa. The 'Michi-no-Eki Ushibuka Kaisakan' near the bridge's end is a vital hub for tourists, where you can experience local seafood and specialties. The bridge serves as a key route for exploring the nearby islands, including Shimojima and Shimoda Island.
As the bridge is exposed to sea breezes, please prepare clothing suitable for windy conditions. If you plan to walk, comfortable walking shoes are highly recommended. Since many local facilities and roadside stations may require cash, please carry Japanese Yen for smooth transactions. Please respect local etiquette and be mindful of any temporary traffic restrictions due to maintenance work.
