The story begins a long, long time ago on what was just another day. At this time, the Izu Peninsula did not exist, so when the god of Mount Fuji looked east all he could see was only the ocean.
As he gazed, the thought occurred to him that perhaps he should create a bountiful land there. As soon as he did, he caused the seabed to rise up. A great red fire emerged from that burned day and night. Finally the burning lava cooled off hardening into the peninsula we see today.
