天子湖 — photo spot in Shimosano, Nambu, Minamikoma District, Yamanashi 409-2302, Japan

A small, tranquil mountain lake framed by forested slopes—ideal for mirror reflections, misty mornings and autumn color. Shoot wide reflections and intimate shoreline details. Best at sunrise for low-angle light and mist; late October–November for foliage. Rural site: access by car or local bus, limited parking; be quiet and respect signage.more
