Yokai 29/100
Wa nyūdō
輪入道
わにゅうどう
Translation: wheel priest
Habitat: Hell; encountered on roads and mountain passes, and occasionally villages
Souls; occasionally snacks on babies
Wa nyūdō appear as giant, fearsome men’s heads trapped within flaming ox-cart wheels. Their heads are shaved like monks’ in penance for sins during life.
Wa nyūdō are servants of hell, but spend most of their time on earth patrolling for the wicked. They are in constant suffering from the flames and the wheel, and take a sadistic pleasure in inflicting pain on others. When they capture a victim—ideally a wicked criminal or a corrupt priest, but often enough just an ordinary person—they drag their victim back to hell to be judged and damned. Then the wa nyūdō return to earth to continue their work, until the sins of their former lives have been redeemed.
When a wa nyūdō is sighted, smart townspeople keep off the roads and stay away from all doors and windows to avoid any notice by this demon. The extra-cautious decorate their homes with prayer charms in hopes that the monster will be repulsed and stay away. Merely witnessing the wa nyūdō is enough to bring calamity upon a whole family. Their souls are torn from their bodies and brought to hell by the wheel.
One famous story from Kyōto tells of a woman who peeked out her window at a wa nyūdō as he passed through town. The demon snarled at her, saying, “Instead of looking at me, have a look at your own child!” She looked back at her baby, who was screaming on the floor in a pool of blood—both of its legs had been completely torn from its body. When she looked back at the wa nyūdō, the child’s legs were in its mouth, being eaten by the mad, grinning monster.
