The idea came from all the tanuki statues I saw in front of Japanese businesses which are meant for good luck. From Wikipedia:
"Statues of tanuki can be found outside many Japanese temples and restaurants, especially noodle shops. These statues often wear big, straw hats and carry bottles of sake in one hand, and a promissory note or empty purse in the other hand. Tanuki statues always have large bellies. The statues also usually show humorously large testicles, typically hanging down to the floor or ground, although this feature is sometimes omitted in contemporary sculpture."
