See the Wedded Rocks of Meoto Iwa at Futami

Off the coast of Futami in Ise, two sacred Shinto rocks stand in the sea: the larger Otoko-iwa, for the male, and the smaller Onna-iwa, for the female. Five shimenawa ropes join them and are replaced three times a year, in May, September and December. The rocks symbolise fertility and marital bliss. In the month before and after the summer solstice the sun appears to rise between them, and on clear winter mornings Mount Fuji can be seen in the distance. Nearby, Futami Okitama Shrine is dedicated to Sarutahiko and known for its many frog ornaments: the Japanese word kaeru means both frog and to return, so visitors pray for the return of lost things or people.
