In the beginning of time, the sun and the moon shared the sky. The people lived in a perpetual state of eclipse where the sun and the moon looked down on them side by side, and never rotated. However, the god of the moon became frustrated with the sun goddess as he was not able to shine as brightly as her, and many looked at the god of the moon as just an accessory to the sky during the day, and not acknowledging him as a grand celestial body. He became very jealous of the maiden made of light in the sky, and decided to play a joke on her.
The god of the moon came down to Earth and picked up all the stray animals he could carry, and called upon Shiawase-no-kami to bring him cats. He called upon the god of death to bring him stray dogs, and he called upon other spirits to set up his elaborate scheme to scare away the goddess of the sun.
When the time came that the moon planned to execute his scheme, he pulled a lever to allow all of the dogs and cats he had gathered to fall on top of the sun while she stood in the sky over the Earth. However, he was surprised to see that the stray animals had been replaced with bunnies. Shiawase-no-kami had informed the sun goddess about what was happening, and she was able to turn the moon’s scheme against him. The bunnies were drawn to the energy of the moon, and in running away he fled to the other side of the cosmos to try and outrun them. For this reason there are bunnies on the moon, and the polarity caused the planets to sky to begin spinning, with alternating cycles of day and night for the god that was currently in charge of the sky.
