Mt. Daisen, a peak in central Japan, is celebrating its 80th anniversary as a national park. 5th and 6th graders at the Daisen Elementary School took recording devices and video cameras into the park to make a music video about the mountain. Leading them is Shinya Kiyokawa, a cutting-edge musician who makes music out of natural sounds. He won a Gold Award at the Cannes Lions International Festival of Creativity. We followed Kiyokawa and the children for 4 months: from initial meeting to the unveiling of the video. Discover the children's thoughts on Daisen and their hometown, their feelings about what they record, and how they choose to share their work.
