The wind god in Japanese mythology is Fūjin.
Fūjin is a Japanese kami associated with wind. He is traditionally depicted as a frightening, red-haired or green-skinned oni-like figure carrying a large wind bag over his shoulders. By opening or closing the bag, Fūjin can release and control the winds.
He is most often shown beside Raijin, the god of thunder and lightning. Together they form one of the best-known divine pairs in Japanese religious art, appearing at temple gates, in Buddhist imagery, and on decorative folding screens. Their partnership represents the storm forces that shape Japan’s weather and agriculture.
Fūjin’s image has a long cross-cultural history. Scholars connect the wind bag and the deity’s visual form with artistic traditions that traveled from the Greek wind god Boreas through Central Asia, India, China, and eventually Japan. This does not make Fūjin identical to Boreas; it describes the movement and adaptation of religious imagery.
Fūjin can also be called Kaze-no-kami, meaning “god of wind.” Susanoo is sometimes described as a storm god, but the direct canonical answer to a question asking for Japan’s wind god is Fūjin.
