Since the ancient times, the sun was a god itself. People live by the sun. Not only people, every living creature, and even the earth itself is living by the sun. We call the children of the sun Hiko and Hime. Hiko as in men, and Hime as in women. After the dark night, which sometimes becomes the world of evil, the look of the morning sun rising makes you feel that life is regenerating. In particular, the first sunrise symbolizes that “no shadows will be present on what burns by itself.”
　Large rocks that stand out were also a subject of faith, where they were considered to be a place where a god dwelled. Especially when two rocks line up, they were considered to represent the heaven and earth or the positive and negative, called the “Couple Rocks” to represent happy marriage, well-being of family, and world peace, or sometimes considered to be Ebisu and Daikoku (two deities of good fortune), where people prayed for a good haul in fishing and safety on the ocean. Along with Couple Trees, etc., they are seen in various places of Japan, and there are also places named after these.
