Daikoku is one of the Seven Lucky Gods of Japan, being a deity of wealth, darkness, the household, kitchen, trade, the earth, agriculture, rice and farmers. Easily recognizable as he wears a flat black hat and carries a sack and hammer. It is not uncommonly for Daikoku to be depicted standing on bales of rice.
Another of the Seven Lucky Gods, Ebisu, is often paired up with Daikoku and as such, if the two are not depicted alone or with the other Seven Lucky Gods the two will be most likely depicted together. This stems from Ebisu being the son of Daikoku. Rats happen to be the animal associated with Daikoku, and is at times seen in depictions of the deity.
