The bridge is the longest toll-free bridge in Japan that spans over the sea.
The structure was built to improve the livelihoods of Kouri Island residents by providing reliable access to the main Okinawa island.
The emerald-green sea color visible from the bridge is caused by the depth of the water and the white sandy seabed.
Kouri Island, located at the end of the bridge, is the setting for the Okinawan version of the Adam and Eve creation myth.
The bridge was designed to minimize environmental impact on the surrounding coral reef ecosystems.
Kouri Big Bridge is a 1,960-meter-long toll-free bridge connecting Yagaji Island to Kouri Island in northern Okinawa. Completed in 2005, it serves as the primary land access to Kouri Island, which is known for its emerald-green waters and coral reefs. The bridge features a gentle curve that spans the shallow, clear ocean channel separating the two landmasses. Its design allows motorists and cyclists to maintain views of the sea on both sides of the road. The bridge is part of the Okinawa Prefectural Road 247. It provides the only direct route for vehicles to reach the island's interior attractions.

Park your vehicle at the dedicated lot on the Yagaji Island side to walk onto the bridge for better photos.
Check the tide charts before visiting to ensure the water is clear and the sandbars are visible for the best scenery.
Drive slowly as the bridge is narrow and prone to high crosswinds.
Do not attempt to stop your vehicle on the bridge itself to take photos, as it is a safety hazard and causes traffic congestion.
