Media | Manga | Anime | Mushishi | A Field Guide to the Mushi

Editor's Note: The following information was collected from the body of an unknown Mushishi, or Mushi specialist. We apologize for the quality of the sketches; given the advanced state of decay of the notebook recovered, we consider it a miracle that even this much text was legible. We present this information here in the hopes that it may someday spare another, perhaps more cautious, Mushishi from meeting a similar fate. May contain minor or tangential spoilers for the first two volumes of the Mushishi manga.


This mushi, which looks rather like a snail shell, is rather common in northern, snow-covered regions and other peaceful, quiet areas. It is something of a pest which has been known to infect the ears of humans and rob them of their hearing. It can be killed with a liberal application of pepper. Or perhaps it was anise. I must find more subjects to experiment on.

A rumor among Mushishi has it that all Un spiral the same way, and if you see one of the opposite nature it is actually a much more dangerous variety that can lead to insanity and death. Sounds paranoid, if you ask me. I'll believe it when I see it.


These mysterious bird-like mushi can be found infecting the dreams of humans. As such, they can only be detected by an experienced Mushishi. One must then track down the physical object which they inhabit, so that they can be eliminated. Unfortunately, depending on the method used, this may prove uncomfortable, or indeed fatal, to the human host. Perhaps there is a method by which this can be avoided?

Some say that when one's dreams are affected by this mushi, one can predict the future, or even influence it. I remain skeptical.


This sketch depicts the method of elimination of the Manako-no-Yamimushi, a rather rare mushi which has the unfortunate tendency to infect the human eyes. The trick, as usual, is getting it out.

Unfortunately, the prospects for recovering the victim's sight are dim. No pun intended. Some notes left by another traveler indicate that moonlight may be required.

Unknown Aquatic Mushi

Sightings of this large water-dwelling mushi have been reported on rare occasions in rivers or estuaries leading towards the sea. Greenish in color, it seems to be rather insubstantial in nature.

Other stories link this mushi to tales of bogs or swamps which have appeared and disappeared overnight. This seems rather unlikely, and I, for one, attribute such theories to poor observation and recording skills.

So-called Kuchinawa

This rather unbelievable sketch is based on a story told to me in a town I passed through not long ago. Theoretically, this impressive mushi lords over an entire mountain and controls all within its domain.

It is not surprising that simple villagers may conveniently attribute almost any phenomenon that they do not understand to the will of a mysterious mushi. Most such tales are greatly exaggerated, and should be taken with all due skepticism.


This diagram shows the removal of a Biku, a mushi reported only on certain isolated islands. It inhabits a victim's upper respiratory system, and reportedly causes them to experience life at a highly accelerated rate of one entire lifetime per day. Of course, the reports of those infected by a mushi may be somewhat muddled.

To extract this mushi, one can use a pin applied to the forehead to create a small opening for the Biku to escape. This obviously requires a rather delicate touch.


The Koda is a rather unusual mushi made of energy and light. It resembles a common rainbow, but can apparently be spotted due to the fact that the ordering of the colors is reversed. They can be difficult to track down, especially if one has trouble remembering which is the proper way around for those colors.

Apparently, if one comes into contact with a Koda, one may thereafter find oneself drawn into a fruitless pursuit of the creature that can last for years on end. Rumors of treasure associated with this mushi are totally unsubstantiated.


This is perhaps the most dangerous mushi discussed thus far. The Watahaki can not only infect humans in some manner that is not well understood, but can also assume a variety of shapes depending on its current situation. The version depicted is in a semi-dormant state resembling a large growth of fungus.

Reports state that this mushi can resort to almost human-seeming tactics to ensure its own survival. This seems quite unbelievable, as mushi of course are not even proper animals. Still, it should be approached with all due caution. I hope to report back later on effective methods of capture and disposal.
