In Japan, kite flying is traditionally a children's play in New Year holidays and in the Boys' Festival in May. In some areas, there is a tradition to celebrate a new boy baby with a new kite (祝い凧). There are many kite festivals throughout Japan. The most famous one is "Yōkaichi Giant Kite Festival" in Higashiōmi, Shiga, which started in 1841. The largest kite ever built in the festival is wide by high and weighs . In the Hamamatsu Kite Festival in Hamamatsu, Shizuoka, more than 100 kites are flown in the sky over the Nakatajima Sand Dunes, one of the three largest sand dunes in Japan, which overlooks the Enshunada Sea. Parents who have a new baby prepare a new kite with their baby's name and fly it in the festival. These kites are traditional ones made from bamboo and paper.
