Kutsuchi no mushi
クツチの虫

Translation: epilepsy worm

This creepy looking fellow is called kutsuchi no mushi, and it lives in your lungs. It has a bird-like beak on its head and sinister white eyes. Its belly is white and segmented like a snakes, and it has a blueish band running down its back. Its tail is bifurcated.

This mushi causes its host to suddenly lose consciousness, dropping to the floor as if dead. They vomit white foam from their mouths and they cannot be roused. These fits last for two to four hours, after which they regain consciousness. Long ago, this sickness was called kutsuchi.* Today we know it as epilepsy (tenkan in today’s Japanese).

Interestingly, Harikikigaki lists no treatment for this infectious yokai. Presumably no known herbal remedies had any effect on epilepsy.

*Originally kutsuchi meant snoring, but at some point it came to be used as a slang for madness or insanity. The fits these patients suffered were thought to be some form of madness, so the disease came to be called kutsuchi.

Haraita no mushi
腹痛の虫

Translation: stomach pain worm

Although you might think it lives in the stomach due to its name, haraita no mushi lives actually lives in the kidneys. It has a black back and a blue belly, sharp eyes, and a large mouth which splits open in a cross pattern.

Haraita no mushi bites on to its hosts with its four-way split Predator-like mouth, causing sudden and intense abdominal pain.

This kind of infection is treated with kaininsō (Digenea simplex), a red seaweed which is commonly dried and used as an insect repellant. Harikikigaki says that ingesting a large amount of this will cause the haraita no mushi to be expelled through diarrhea.

This one in particular interested me, because it sounded so specific and it was the first time in reading Harikikigaki that I came across this particular herbal cure. I looked up the herb it referred to and read that in addition to insect repellant, in old herbal medicine it was frequently used as a cure for roundworm infections. So it it seems that this yokai may actually be inspired by the ascaris roundworm. The symptoms match, as well as the cure. And to be honest, parasitic worms scare me more than any ghost or monster, so this particular yokai is pure nightmare material to me.

Kagemushi
陰虫

Translation: shadow bug

Kagemushi are disease yokai which possess the genitals of men and women.

When an infected couple has sexual intercourse, the kagemushi become excited. This excitement culminates during climax, at which point both the male and female kagemushi erupt forth, gushing liquids all over the place. A white liquid is discharged from male hosts, and a red liquid from female hosts*. Although these liquids flow forth from both humans, they are in fact vomited up from mouths of the kagemushi. Afterwards, male and female kagemushi entangle each other in their wire-like limbs, becoming inseparable.

Those possessed by kagemushi display a severely increase libido, perpetual horniness, and constantly behave in a lewd manner. Treatments for kagemushi infections exist, but are only passed down orally. Harikikigaki does not list any.

*This description relates to the ancient Buddhist “red and white drops” theory of sexual reproduction, in which the white drops expelled by the male combine with the red drops expelled by the female, become implanted in the female, and then become a seed. This seed then undergoes a series of metamorphoses before it transforms into a fetus. Harikikigaki attributes the expulsion of these drops to the kagemushi. In other words, it’s not the birds and the bees–it’s the bugs!
