This is a figurine of a "tanuki" ("raccoon dog") outside a British eatery in Shinjuku.
In Japan, it is common to see some or the other kind of lucky charm in front of business establishments primarily, shops and restaurants. Many Japanese people believe that certain animals bring good fortune and as such they place certain objects resembling these animals at the entrance of their business place.
These tanuki statues usually have a big belly and somewhat disproportionate body parts. They are shown wearing turtle shell hats and carrying a promissory note (sometimes replaced by an empty purse) in one hand while the other hand holds a sake bottle.
This animal is supposed to bring good fortune to business because of its 8 special traits:
1. The big belly signifies bold and calm decision-making,
2. The promissory note represents the trust and confidence
3. The bottle of sake represents Virtue!
4. The big tail represents steadiness and strength
5. Oversized testicles symbolize financial luck!!
6. Big eyes symbolize the capability to judge the environment and making good decisions
7. The turtle shell hat symbolizes readiness and protection against bad weather (meaning bad times)
8. The friendly smile which supposedly means friendly attitude towards customers.
The disproportionate size of the belly, tail, eyes and testicles give the “Tanuki” a comical and humorous appearance. The Japanese folklore has many stories related to the tanuki. The tanuki is generally reputed to be mischievous and funny and at the same time gullible and absentminded.
