Lake Onogawa is located in Kitashiobara Village, Yama District, Fukushima Prefecture, and is one of the three famous lakes of the Urabandai area. The lake's history is deeply tied to the dramatic eruption of Mount Bandai in 1888, where debris flows from the mountain's collapse blocked the Onogawa and Nagase rivers, creating the lake. With an area of approximately 1.4 to 1.72 km², the lake features a complex shoreline surrounded by undulating terrain. The scattered islands within the lake are affectionately called the 'Matsushima of Bandai,' creating a harmonious landscape with the surrounding mountains and forests. The southern shore is easily accessible via the Bandai-Azuma Lake Line, making it an ideal spot for a scenic drive.
The formation of Lake Onogawa is a testament to the dynamic power of nature. The landscape was fundamentally reshaped by volcanic activity in the late 19th century. The water that feeds the lake flows from the pristine waters of the mountains, passing through the Onogawa Fudo Falls. This water is recognized as one of the 'Top 100 Selected Waters' in Japan, celebrated for its exceptional purity. This intersection of volcanic history and natural beauty has shaped the area into a premier scenic destination.

The most striking view of Lake Onogawa is the sight of uninhabited islands dotting the water, framed by the surrounding mountain ranges. The view from the southern shore is particularly breathtaking when enjoyed during a drive along the Bandai-Azuma Lake Line. Additionally, the natural environment around the Onogawa Fudo Falls, the source of the lake's water, is a vital part of this scenic area. The landscape changes beautifully with the seasons: the larch forests along the shore turn a brilliant gold in autumn, while the water surface reflects vibrant shades of green during the lush spring and summer months.
