Just inside the entrance to the beach park at Cape Inamuragasaki is a stone historical marker that reads:
On May 21, 1333, it was difficult for Nitta Yoshisada to attack Kamakura from the land, so he thought about going around this cape in Inamuragasaki. It is here that they prayed to the sea god for a retreating tide by throwing a golden sword into the water.
