There are seven lucky gods that are celebrated in Japan. One of them is Ebisu, god of prosperity and fishermen. He traditionally holds a Tai, or red sea bream (pagrus major), an auspicious fish that is often used as a symbol of good luck. Just looking at this picture means that glorious things are about to happen in your life.
I also happen to be a fan because there is a delightful Japanese brew called 'Yebisu' that is also named after the cheerful fellow.
