Lake Onogawa is one of the three iconic lakes of the Urabandai area, located in Kitashiobara Village, Yama District, Fukushima Prefecture. The lake was born from a dramatic geological event: the 1888 eruption of Mt. Bandai caused a massive debris flow that dammed the Onogawa and Nagase rivers, creating the lake we see today. With an area of approximately 1.4 to 1.72 km², the lake is surrounded by complex, beautiful terrain. The scattered small islands within the lake are often referred to as the "Matsushima of Bandai," creating a harmonious view with the surrounding mountains and forests. The southern shore is easily accessible via the Bandai-Azuma Lake Line, making it a popular destination for scenic drives.
The very existence of Lake Onogawa is tied to the dynamic power of volcanic activity. The landscape was reshaped by the debris flows from the late 19th-century eruption of Mt. Bandai, which carved out the current basin. Furthermore, the lake is fed by incredibly pure water flowing from the mountains through the Onogawa Fudo Falls. This water source is recognized as one of the "100 Best Waters in Japan," a testament to its pristine quality. This landscape, born from nature's fury, has evolved into a serene and beautiful scenic spot.

The most striking view at Lake Onogawa is the sight of the uninhabited islands dotting the water against the backdrop of the surrounding mountains. The view from the southern shore is particularly spectacular, especially when driving along the Bandai-Azuma Lake Line. The natural environment surrounding the Onogawa Fudo Falls, the source of the lake's water, is also a vital part of this landscape. The lake offers a different face to visitors depending on the season: from the vibrant greenery of fresh leaves in spring to the stunning golden hues of the larch forests in autumn.
