Rōjinbi

[1] It is said to appear along with an elderly person,[3] and cannot be extinguished by water but can be if beat with animal skins.

[1] If, for instance, one comes across a rōjinbi on a straight stretch of road, holding one's footwear over one's head will prompt it to veer off to another path.

[1][4] It is sometimes called 'tengu no miakashi' (天狗の御燈, literally, 'tengu's lantern'), but this actually means an onibi that a tengu has lit.

[5] Senkyō ibun (仙境異聞, literally, 'strange tales of enchanted lands'), by the late Edo period scholar Hirata Atsutane with the aid of a boy who apparently returned home safely after being abducted by tengu, claims that tengu eat fish and birds, but not other animals.

Furthermore, according to the collection of writings known as Heisuiroku (秉穂録), somebody was once cooking meat in the mountains when a gigantic, seven shaku (over two metres) tall mountain priest appeared, but, despising the stench of roasting flesh, he disappeared again.
