Love is in the air as Valentine's Day arrives! This holiday is often associated with various romantic symbols, such as Cupid or Romeo and Juliet, the famous star-crossed lovers of William Shakespeare. Symbols of love can also be found in nature, such as red-crowned cranes, seen today in the reed marshes and frozen lakes of Hokkaido Island, Japan. These graceful birds engage in captivating mating dances to strengthen their lifelong bond—and symbolise good fortune, longevity and fidelity in Japanese culture. These gentle creatures even inspired a traditional paper craft, the origami crane; according to legend, folding a thousand cranes can grant wishes.
