An old stone-paved road in dappled sunlight. We take a walk on the Kisoji, a mountain road connecting Nagano and Gifu Prefectures. A key route during the Edo period, today it attracts visitors from across Japan and the world. A group of 3 families on an 8-kilometer hike. A man going for a run on the uneven trail. People taking the time to be alone and reflect. For 3 days in early summer, we spoke with people travelling on the old road.
