March 3rd is the Doll’s Festival, Japanese people display a set of dolls and pray for the sound growth of girls in the family.
On this day, the “Nagashi-biina” event is held at Awashima Shrine in Wakayama City, where hina dolls delivered from all over Japan are put on a boat and floated out to sea.
Originally, there was a Chinese custom of going to the waterfront on March 3, or the Peach Festival, to hold an exorcism ceremony, which was then introduced to Japan.
