The Naidaijin Bridge spans 199.5 meters across a deep gorge, rising 86 meters above the water surface between Misato and Yamato towns.

Built in 1963, this engineering structure held the title of largest arch bridge in East Asia, requiring an investment of 151,557,000 yen for construction.

The name Naidaijin originates from the Heike clan refugees who settled in this valley after their defeat at the Battle of Dan-no-ura.

The bridge serves as a crucial connection for forest resource development between Kumamoto and Miyazaki prefectures, with a road width of 5.5 meters.

The structure features a two-tier through-truss design with a main span of 153 meters, connecting to multiple forest roads in the national reserve.
