APPEARANCE: Yamawaro are minor deities of the mountains, closely related to other nature spirits such as kappa, garappa, and hyōsube. They are short creatures resembling boys of about 10 years of age. Their heads are covered in long brown hair and their bodies is covered in very fine, light hair. They have a short torso and two long legs, on which they walk upright. A yamawaro’s most distinguishing feature is the single eye in the middle of head. They are skillful mimics, copying the sound of falling rocks, wind, dynamite, tools, and can even learn to speak human languages and sing human songs.

INTERACTIONS: Like their cousins the kappa, yamawaro despise horses and cows, and often attack them on sight. They love the sport of sumo, which they are better at than any human. They also enjoy sneaking into homes to nap and take baths, leaving a thick film of grease and hair in the tub when they are done.

Yamawaro are frequently encountered in the mountains by woodcutters, and are known to help with work. If properly thanked, and offered food for their services, a yamawaro is likely to return to help again. However, care must be taken when feeding a yamawaro. If the amount of food is less than what was promised, the it will grow extremely angry and never return. If the food is offered before the work is performed, it will simply take the food and run away.

ORIGIN: One theory from Kumamoto says that yamawaro and garappa are actually different forms of the same yokai. During the cold months, these creatures live in the mountains as yamawarawa, while during the warm months, they live in lakes and rivers as garappa. Every year on the fall equinox, all of the country’s garappa transform into yamawaro and travel from the rivers to the mountains in a mass migration. They return on the spring equinox and transform back into garappa. Villagers who build their houses in the pathway of these massive yokai migrations are prone to find holes, gashes, and other damage caused by yamawaro angry at having their path blocked by a house. People who witness the springtime return of the yamawaro often catch deadly fevers.

This theory is supported by the fact that these creatures share so many traits in common with one another, and because it is extremely rare to see garappa in the winter. However, it is also possible that these aquatic yokai simply go into hibernation during the colder months, and that the similarities between garappa and yamawaro are simply coincidences.
