Tour Japan's first rockfill dam and be awed by its impressive embankment
About this spot
Built in the upper reaches of the Asahi River, this dam is known as Japan's first rockfill dam. The impressive embankment surrounded by lush green mountains is awe-inspiring, and the contrast with the calm surface of the reservoir creates a beautiful view. The observation area allows you to study the dam's structure in detail, offering educational discoveries like a school field trip. It's also interesting to observe how the water flowing from this dam will become the stage for tonight's fireworks.
