Shiromaru Dam Control Lake (Okutama) offers calm reservoir reflections framed by forested ridges — excellent for seasonal color (autumn foliage, spring greenery) and misty mornings. Accessible via JR Ome Line to Okutama + local bus or by car with small parking near the dam. Best at sunrise for soft light and fog, or late afternoon for warm side lighting; weekdays and early mornings avoid crowds. No special entry permit, but drone use is likely restricted — check local rules.
