The Toga Bridge is a steel arch structure spanning 368 meters across the Sho River with a deck width of 8.5 to 9 meters. It carries traffic through mountain terrain and forms part of National Route 471, connecting communities and facilitating access to surrounding areas.

An earlier suspension bridge built in 1937 was destroyed by fire in 1965, leading to the need for a replacement structure. The current arch bridge was constructed starting in July 1999 as part of a bypass project for National Route 471.

The bridge links communities in the Sho River valley, allowing people to cross easily and gather together for events and daily life on both sides of the waterway.

The structure provides easier access to Nagasaki Hot Springs and Lake Komaki Dam, reducing travel times across the region. Road conditions are generally good and the span offers views of the surrounding mountain landscape from the deck.

The original bridge towers from the earlier structure still stand beside the modern arch bridge, visible reminders of how transportation infrastructure has changed in the area. They give visitors a chance to see the physical contrast between old and new engineering.
