Awashima jinja is a shrine for women and is famous for its enormous collection of dolls.
Every year on March 3rd, Awashima jinja is home to a doll festival called nagashi bina, in which boatloads of hina ningyo are launched into the ocean. As the boats are rocked by the waves, the dolls fall overboard and sink into the ocean. It is believed that the dolls will take away the sicknesses and bad luck afflicting their former owners, and the ritual has become very popular.
Love the ideas of rituals around dolls - sometimes our little gang wonder what will happen to our collections when we've 'outgrown' them.
