The Momijidani Otsuribashi Suspension Bridge (Maple Valley suspension bridge) is the longest suspension bridge in Tochigi.
It spans 320 meters across the Hokigawa river at the Shiobara dam. Its a pedestrian only bridge and has some great views,
Especially in Autumn.
Apparently its without any solid beams or girders supporting it – so all wire and tension. Admission is 300 yen
