It was commissioned to create a work incorporating the sea of Naoetsu in Joetsu City, Niigata, Japan, and I visited the site in January 2021. At the time there was still a lot of snow, but I was able to get a great view of the Sea of Japan as the sun was setting. The sea was so beautiful that I thought that any installation would be a distraction from the scene created by the Sea of Japan.​ What I could do was to make a work of art that would only be possible by incorporating the scene of this place. I focused on the phenomenon that the sky was reflected in the sparse seawater left on the beach. And arranged the seawater in geometric shapes that do not exist in nature. At the same time, it also focused on the ebb and flow of the tides, aiming to create a work that is generated by the power of the sea. The idea was conceived by Takatoku Nishi. The main members of this project were seven people from the Third Laboratory of the Department of Design at Tokyo University of the Arts: Yoshiaki Kanamori, Kyohei Tsuchida, Yumeo Nakayama, Kotone Muto, Sanami Yamada and Taro Suzuki.
