Ainu: Retaruseta
The Ainu, the indigenous inhabitants of Hokkaido, knew the Hokkaido wolf as the high-ranking god Horkew Kamuy. In Hokkaido’s Tokachi and Hidaka regions, there flourished versions of a myth about a white wolf that mated with a goddess, or sometimes a Japanese court lady, and the offspring from this union became the ancestors of the Ainu people. Several regional versions of this origin myth exist, and some feature a white dog rather than a white wolf. The difference between wolves and dogs appears to have been less important to the Ainu, since both wolves and dogs inhabited much the same space in their classifying imagination. One version of this myth from Shizunai, in the Hidaka region, explains that the god of the mountain Poroshiri-dake, Retaruseta Kamuy (the white-wolf god), could not find a suitable mate, even though he searched the entire island. So Retaruseta Kamuy summoned his divine powers, seeing all the way to lands across the seas, and in time spotted a mate in a distant country. Again drawing on his divine powers, he coerced the woman to get in a small boat, cross the seas, and once on the island become his wife. From this union, it is said, the Ainu people were born.
