The park covers a vast area reclaimed from the sea during the bridge construction project.
The Great Seto Bridge system spans 13.1 kilometers, making it one of the longest double-deck bridge systems in the world.
The commemorative tower, known as the Seto Ohashi Tower, rotates 360 degrees as it ascends, offering a panoramic view.
The park layout is intentionally designed to align with the axis of the bridge structure.
The construction of the bridge project utilized a pioneering underwater welding technique to handle the strong tidal currents of the Seto Inland Sea.
Seto Ohashi Commemorative Park is located on Banno Island at the foot of the Great Seto Bridge, a complex of ten bridges connecting Shikoku and Honshu. The park was established to commemorate the 1988 completion of this massive engineering project. It features the Seto Ohashi Commemorative Museum, which details the bridge's construction history. Visitors can access a 108-meter-tall observation tower providing panoramic views of the Seto Inland Sea. The grounds include expansive lawn areas, water features, and outdoor sculptures. The site is a primary location for observing the interplay between industrial infrastructure and the surrounding archipelago. It serves as an educational hub for structural engineering history in the Kagawa prefecture.
The grassy area near the seaside edge, aligned with the bridge's massive steel suspension cables.
Bring binoculars to identify the various islands visible across the Seto Inland Sea.
Carry sun protection, as the park features large open areas with limited natural tree cover.
Check the wind conditions before visiting if you plan to use the observation tower, as service may be suspended during high gusts.
Do not attempt to walk across the bridge deck from the park, as it is strictly closed to pedestrian traffic.
The observation tower typically closes during severe weather conditions, such as high winds or lightning.
