Panoramic viewpoint above the 上日川ダム reservoir with mountain backdrops, clean dam lines and reflective water—great for reflections, autumn foliage, misty mornings and long‑exposure waterscapes. Best at sunrise or golden hour for warm light on the ridgelines, and at blue hour for calm reflections. Autumn (late Oct–Nov) and early spring offer strongest color; winter can deliver snow-capped peaks and crisp air. Accessible by car with a small parking area at the 展望広場; no entry fee. Weekday mornings/早
