The bridge is located within the Aya UNESCO Eco Park, which encompasses one of the largest remaining stands of primary laurel forest in Japan.
The structure was designed specifically to minimize environmental impact on the surrounding protected ecosystem.
It is frequently used as a vantage point for observing migratory birds that inhabit the Kyushu mountain range.
The Ayakita River gorge below the bridge is known for its steep, rugged terrain and natural rock formations.
The bridge floor is constructed with an open-grid design, allowing visitors to see the river gorge directly beneath their feet.
Aya's Teruha Suspension Bridge is one of the highest pedestrian suspension bridges in Japan, spanning 250 meters across the Ayakita River at an altitude of 142 meters. It provides access to the Aya Biosphere Reserve, a large expanse of warm-temperate evergreen forest designated by UNESCO. The bridge is constructed of steel and reinforced materials to withstand high winds and heavy forest humidity. The structure connects the mountain trails that wind through the surrounding primary laurel forest. Visitors can observe the canopy layer of the forest directly from the walkway. The surrounding area serves as a critical habitat for native Japanese wildlife, including wild birds and diverse plant species.
The north end of the bridge offers the clearest wide-angle shot of the entire span against the backdrop of the valley.
Wear comfortable, sturdy hiking shoes as the bridge leads to several unpaved forest trails.
Bring a light jacket or windbreaker, as wind speeds are significantly higher on the bridge deck compared to the forest floor.
Check the official town website for severe weather alerts before departing, as high winds often result in temporary closures.
Do not attempt to hike the further forest trails if you are unprepared, as the terrain becomes steep and slippery immediately after rain.
May be closed temporarily during severe weather events, including heavy rain or high winds; no recurring weekly closure provided.
Avoid running, jumping, or shaking the bridge, as the oscillation is amplified for other visitors.
