The Tōriike are famous for their beautiful landscape and there are only few places in Japan which feature such beautiful shades of shining blue seawater A few local Shimoji-jima legends surround these two picturesque ponds. One popular tale tells of how the ponds were created. The story goes; two fishermen caught a mermaid and being friendly neighbors they decided to cut her in half and share her. On the same night of the catch they heard sobbing coming form the sea beckoning her to come back. The mermaid replied the she could not come back as she was cut in half. The voice from the sea told her that three big waves would be sent to bring her home. Not long after a tsunami came and washed the fishermen’s home away along with the mermaid. When the water receded all that was left was the two ponds of Tooriike.
