If you've ever been walking at night and heard strange footsteps following you, only to turn around, terrified, and find nothing there, you've encountered the yōkai
known in Nara Prefecture as Betobeto-san.
It's said that if you stand to the side of the road and say, "Betobeto-san, please go on ahead," that the footsteps will stop and you can continue walking in peace.
