Yoroi no Sode is a huge cliff, standing at a height of 65 m and a width of 180 m with an angle of 70 degrees. It was designated as a national natural monument in 1938. *Magma penetrated into its underground layers after the formation of the Sea of Japan. When it cooled, it created lengthwise and crosswise cracks, which crossed with each other perpendicularly and formed a pattern that resembles the sleeves (= sode) of a samurai’ s armor (= yoroi). Takanosu-iwa (hawk’s nest rock) and Hachinosu-iwa (beehive rock) located on an extended line of Yoroi no Sode are natural sculptures, formed by wave erosion of the rocks of Yoroi no Sode.
≪Shortened version from　*≫ Visitors can observe beautiful columnar joints. These cliffs are named after their appearance, resembling the sleeves (= sode) of a samurai’s armor (= yoroi).
