In Japan, Children’s Day, or Kodomo-no-hi, falls on 5th of May. To be precise, however, it is actually celebrated as the Boys’ Festival. To drive away bad spirits and celebrate the future of their sons, families display Gogatsu-ningyo, samurai dolls and their armaments, indoors like Hina Matsuri Dolls, and hoist Koi-nobori, cloth carp streamers.
Iris flowers called Hana Shobu, which bloom in early May, are placed in homes to ward off evil. It is customary to have a bath known as Syobu-yu, filled with floating iris leaves and roots not only to drive off evil but also to prevent disease.
Kashiwa-mochi, rice cake stuffed with sweetened bean paste and wrapped in an oak leaf, is eaten on the day. Since oak tree doesn’t shed old leaves until new leaves grow, it is considered a symbol of the prosperity of one’s descendants.
