Large swirling waves, small quiet waves. The blue ocean wave design is a pop design of large and small arches overlapping each other like a fan. This design is a great motif for people around the world who are familiar with the sea, and can be seen not only in Japan but also in Egypt and Persia. It also appeared in the Tale of Genji, a tale that originated in the Heian period (794-1185), and became popular again among the common people in the Edo period (1603-1868). The symbol of abundant blessings and infinity has come to be loved as an auspicious motif, and is given as wedding gifts and housewarming gifts.
