Ōji Dam, completed in 1999, is a gravity concrete dam located in Asago, Hyogo Prefecture. The dam forms Lake Shūmai, offering serene views and a peaceful atmosphere. While less known than nearby attractions like Takeda Castle, Ōji Dam provides a quiet escape with a park area upstream. Visitors can obtain a dam card from the management office (often unattended; a self-addressed stamped envelope works) or the Yabu Civil Engineering Office. The dam is accessible via Route 312 from the Wadayama IC on the Bantan Road, making it a convenient stop for those exploring the region.
