So a random stroll through Wikipedia reveals that Tanuki or "raccoon dogs" have a fascinating place in Japanese folklore. It seems Nintendo often includes tanuki or tanuki aspects in its games. In particular, Tom Nook and his adoptive children in the Animal Crossing games are tanuki!
In Japanese (at least, anglicized), Tom Nook's name is "Tanukichi". I originally assumed that "ichi" must be a diminutive suffix indicating cuteness, however the closest thing I could find spelling wise is "chichi" which seems to be an informal term for father like "dad". However it's entirely possible that the anglicized spelling similarity is totally coincidental.
Is there any obvious etymology of "Tanukichi" in the original Japanese?
