Hashigui Rocks are 40 large and small rocks extending across the sea 850 m from Hashigui, Kushimoto-cho to Oshima Island.
Legend has it that once upon a time Kobodaishi Kukai laid a wager with Amanojaku (heavenly evil spirit) if he could build a bridge to Oshima Island before dawn. Seeing that Kukai would win, Amanojaku cheated Kukai by mimicking a rooster call. Hearing this, Kukai thought the day broke and gave up completing the bridge. Consequently only the posts remained.
At low tide, the path to Benten Island in the middle of the way appears, which amuses tourists. The rocks are located in Yoshino-Kumano National Park. Hashigui Rocks are designated as a national Natural Treasure and selected as one of Japan’s 100 Fine Sunrise Spots.
