Japanese Mythology: Hotei - Like Daikoku, he stands for wealth. But he is also the god of laughter and happiness by being content with what you have. He is depicted as a laughing fat man with a bag of rice over his shoulders and kids. On some pictures, he is shown sitting in a cart drawn by children.
A Japanese Tengu ("heavenly dog"). Buddhism long held that the tengu were disruptive demons and harbingers of war. Their image gradually softened, however, into one of protective, if still dangerous, spirits of the mountains and forests. Tengu are associated with the ascetic practice known as Shugendō, and they are usually depicted in the distinctive garb of its followers, the yamabushi. - wiki
Ame-no-Uzume (天宇受売命 or 天鈿女命) is the Japanese Goddess of merrymaking and dance. She is the one who lured the sun Goddess Amaterasu to come out of her self-imposed exile in a cave, returning sunlight to the world. She overturned a washtub and began to dance on it, to the delight of the surrounding Gods and Goddesses. Their laughter at her antics made Amaterasu curious enough to step out of her cave.
