Visitors praise Watarase Retarding Basin Sano for its vast, surreal scenery and hybrid beauty of nature and man-made structures. It's a wonderful spot for various outdoor activities like walking, cycling, and birdwatching, offering a refreshing escape. Some caution is advised regarding wildlife and parking hours.
"I can only say this is a great open place to visit. Utterly wonderful and the scenery is even surreal or somewhat foreign in some parts.
You can enjoy walking, running, cycling, skateboarding, inline skating, birdwatching, fishing (with a proper permit under regulations) or doing whatsoever (other than camping or granping related activities that are pretty restrictive), whilst appreciating the true hybrid beauty of old grand man-made flood control works and the nature’s self assertion in details.
Oh, beware of wild boars and Japanese deers, do not provoke them for your safety, as well as the open hours of the parking lots so as not to be locked in."

"I visited here for the first time. It's very spacious, isn't it? I was able to take a walk on a sunny day and refresh myself. It was wide and far away, so I couldn't see it well, but the national rowing competition was being held."

"I arrived at dawn, when rain had just stopped. It was foggy and cloudy at first, but as time passed golden light trickled through the forests lining the massive lake. The clouds parted and Mt Fuji came into full view. There were flocks of Smew and pairs of swan on the crystal clear water."
