The Legend of Goshado: A Japanese Folktale by Terri Karsten and Sheila Dennison
From Wagonbridge Publishing:
Watch out! Here they come!
Who are these demons with their sharp claws and terrible teeth?
They are Namahage.
They come stomping and roaring down from the mountain to steal any chickens and children they can find.
How will the villagers ever stop them?
