When Buddhism entered China from the Greco-Buddhist world of Gandhara, it carried Hellenistic wind-god imagery: the wild-haired airborne form associated with Boreas and the great wind bag motif linked to Aeolus.
These Greco-Buddhist forms later passed into Japan through Chinese Buddhism, where they were adapted into the wind god Fūjin. The Gods took new names, but the Hellenic image endured from Greece to Japan.
