The venerable legend of "The White Rabbit of Inaba," and the fable of "The Tortoise and the Hare" are proof that Japanese have been interested in rabbits through the ages. The fact that these creatures are so prolific has made them an appropriate symbol of wealth.
Perhaps the first linkage of hoppers and the moon came from India, where one legend tells of a rabbit that cannot bear to see people starve and jumps into the fire so they can have food. As a reward for this self-sacrifice, the god Indra is said to have taken the rabbit to the moon. The story then traveled to China. There, the rabbit has become a pharmacist, mixing medicines with mortar and pestle.
The tale then passed to Japan, where the rabbit is pounding mochi rice cakes, instead of pulverizing medicinal herbs. All over the world, people have likened the shadows on the moon to all sorts of things, but the Japanese have always been infatuated with the idea of the rabbit pounding mochi. This can be seen at traditional confectionary shops throughout the nation, where people stand in line to buy cakes with a rabbit motif for the autumn moon-viewing season.
Good Information...from some random site!
I still believe the bunny is preparing for the special ones arrival...
