Sasagawa Nagare is a scenic 11-kilometer stretch of coastline in Murakami, Niigata, characterized by unique rock formations carved by the Sea of Japan. The area features jagged cliffs, sea caves, and small coves designated as a Prefectural Natural Monument and part of the Sado-Yahiko-Yoneyama Quasi-National Park. The coastline is composed primarily of sedimentary rock that has been sculpted by intense waves and wind. Visitors can observe distinct rock shapes like the Meganewia (Glasses Rock). The area remains accessible throughout the year, with clear water quality that draws swimmers during the summer months. Rail travelers can view the rock formations directly from the JR Uetsu Main Line tracks running along the coast.
