Enjoy views of the calm waters of the dam lake and surrounding verdant mountains
About this spot
An artificial lake created by the Ogochida Dam, it is a signature scenic spot representing Okutama. The lake surface, surrounded by verdant mountains, changes its appearance with the seasons and weather, shimmering in deep green during summer. From the dam's embankment, you can enjoy a panoramic view of both the lake and mountain ranges, and there are shops and a visitor center, making it perfect for a rest. A short walk along the lakeside path offers the tranquility of nature that seems hard to believe is a day trip from the city center. Before the evening fireworks, fully experience Okutama's magnificent natural scenery.
