TRANSLATION: wild mallet (named for its mallet-like shape)
HABITAT: fields and grasslands; found all across Japan
DIET: carnivorous; usually feeds on small animals like rats, mice, rabbits, birds

APPEARANCE: Nozuchi are one of the earliest known yokai recorded in Japan histories. They are powerful and ancient snake-like spirits of the fields known for their bizarre shape and habits. They are short, fat creatures shaped like mallets, about fifteen centimeters in diameter and just over one meter long. They have no eyes, nose, or any other facial features save for a large mouth located on the top of their head, pointing towards the sky. Their bodies are covered in a bristly fur, much like a hairy caterpillar.

BEHAVIOR: Nozuchi make their homes inside of large trees, particularly on the tops of hills. They are slow movers, and move about by rolling and tumbling down slopes, then slowly inching their way back up. They most often feed on wildlife – mice, rabbits, squirrels, and other small animals – however they are able to eat things much larger than they are. In Nara, they are known to feed on deer, which they can devour in a single bite, pulling the whole animal into their small, stumpy frame.

INTERACTIONS: Nozuchi have been known to attack humans who come near their nests, rolling downhill and snapping at their feet. Their bites are very dangerous to humans, resulting in terrible, mangled wounds which quickly lead to a high fever and death in most cases. A person who is touched or even merely seen by a tumbling nozuchi can contract this fever and possibly die. Fortunately, nozuchi attacks are easily avoided by sticking to higher ground where they cannot tumble, or by climbing a tree quickly if no other high ground is available.

OTHER FORMS: Nozuchi can transform into a humanoid shape, though they rarely are seen in this alternate form. They take the shape of a human priest, but with no eyes, nose, hair, or ears. The only feature on the head is a large gaping mouth pointing upwards towards the sky. Wicked monks who are banished from their temples to live in the wilds sometimes gradually turn into nozuchi, and are more likely to maintain a humanoid form than a serpentine one. Care should be taken not to confuse a shape-changed nozuchi with a nopperabō, which has a similar appearance but poses a different threat.
