Large open-air rotenburo at Watarase Onsen offers steaming pools framed by Japanese cedar and mountain views — great for atmospheric shots of steam, reflections and onsen architecture. Best at early morning (mist+soft light) or golden hour; winter yields dramatic steam against cold air. Facility is paid entry, gender-separated bathing (no photographing inside mixed nude areas); shoot exteriors, terraces, signage and landscape. Accessible by car with on-site parking; weekdays are quieter. Respect
