Ase Valley is a scenic gorge in Hidaka-cho, Toyooka City, Hyogo Prefecture. It stretches across the upper reaches of the Ase River, which originates near Kanayama Pass at an elevation of 760 meters. Surrounded by lush broadleaf forests, the valley is home to numerous waterfalls collectively known as the 48 Waterfalls of Ase. The approximately three-kilometer-long gorge offers beautiful scenery throughout the year, from fresh spring greenery and summer foliage to brilliant autumn colors.

Among the many waterfalls scattered throughout the valley, five are especially well known as the Five Great Waterfalls of Ase. Each has its own character, shaped by the surrounding rocks, flowing water, and local legends.
