This special program features the encounter with stunning canyon sceneries. In Japan, we have thousands of falls, which act as training places for mountain worship. For instance, the seven big falls of Fudo Myo O (god of fire) in Nara Prefecture: a hidden place for "Shugen-do" practitioners. Also, in Yakushima, an island registered as World Natural Heritage, there is the big fall on a granite monolith. Japanese canyoneers navigate you to these "two superb locations of the secret landscapes." In the valleys, cascades bring out extraordinary sounds and river water brings out innocent blue. We tackled audio-visual technical challenges on the field with our newest action cameras and 3D audio recorders, bringing you to enjoy the realistic feeling and binaural sound of the valleys.
