The name of the coast, Koiji (path to love) originates from a tragic love story. The legend goes: "Once upon a time, there was a young woman named Nabeno and a young man named Kanzaburo. They fell in love, and met every night on the beach, with Nabeno burning a fire as a sign. However, one night, another young man who had a crush on Nabeno burned a fire in a dangerous spot, so as to deceive Kanzaburo. Kanzaburo was lured by this false sign, and drowned in deep water. Nabeno committed suicide after him, throwing herself into the sea." In memory of this legend, statues and Shiawase No Kane (bell of happiness), a heart-shaped monument, are built on the beautiful beach of white sand.
