This is the "Regishi Island Strategies and Water Marks", and the frame of the water level observatory is lined with "Yurikamome", which rests its wings in the evening. Behind you can see the bridge in the shape of a majestic helmet of Chuo-ohashi Bridge. It's a winter tradition.
"Yurikamome" is also called the Tokyo bird and is designated as a bird in Tokyo.
