Spanning 13.1 km across the Seto Inland Sea, the Seto Ohashi Bridge is one of the world's longest two-tiered bridge systems, connecting Honshu and Shikoku. A symbol of Kagawa with stunning views and night illumination.
The 108m rotating observation tower offers 360-degree views of the bridge and the islands of the Seto Inland Sea. The cabin rotates as it ascends, so you see the entire panorama without moving.
The bridge is illuminated on weekends, holidays, and special occasions. Colors change seasonally — white, blue, green, rainbow. Check the schedule for the best experience.
The bridge has two tiers — cars on top, trains below. Watch from the Memorial Park as JR trains cross the bridge. The Marine Liner from Takamatsu to Okayama is the most frequent.
The free park has a playground, fountains, and green spaces. The adjacent museum tells the bridge's construction story — a 9.4-year engineering feat completed in 1988.
Ride the JR Marine Liner across the bridge for breathtaking views from inside the train. Sit on the left side (heading to Okayama) for the best sea and island views.
