Yamauba is the fairy of the mountains, which have been under her care since the world began. She decks them with snow in winter, with blossoms in spring ... She has grown very old. Wild white hair hangs down her shoulders; her face is very thin. There was a courtesan of the Capital who made a dance representing the wanderings of Yamauba. It had such success that people called this courtesan Yamauba though her real name was Hyakuma
