Overview
Kimimori Sarashina, a researcher of local stories, summarizes the features of the kitsunebi as follows: in places where there was no presence of fire, mysterious flames like those of a paper lantern or a torch would appear in a line and flicker in and out, with fires that had gone out sometimes appearing in yet another place, so that if one attempted to chase after what was behind all this, it would disappear in the middle.
When they appear between spring and autumn, they show up especially in hot summers and appear easily when it is cloudy when the weather is changing.
They are said to appear from ten to several hundred in a line, and just when one thinks that they have increased, they would suddenly disappear, then multiply once again.
In the Nagano Prefecture, many lights like that of a paper lantern would appear in a line and flicker.
The line's length spans across up to one
ri (about 500–600 m).
Generally the color of the fire is red or orange,
but there have been several examples of witnesses that have seen blue flames.

, these atmospheric ghost lights are called "chūko" (宙狐).
Different from the average kitsunebi, they float at relatively low altitudes, and thus in Toyohara village,

Similarly, on Ryūgūjima, Tamatsu village, Oku District, the atmospheric ghost lights that appear at night with signs of coming rain that are about as big as paper lanterns are called chūko. Sometimes they would fall to the earth and illuminate the surroundings, and then finally disappear without a trace. Enryō Inoue, a yōkai researcher from the

True identity

In various folk legends and writings of the Edo Period, there are many things said about foxes concerning how their breath would glow,
how they would strike with their tails to light a fire,
and how they would have a glowing ball called the "kitsunebi-tama" (kitsunebi ball),
among other tales. The

, when fishermen capture kitsunebi with their nets, there would be a kitsunebi-tama caught in their nets, and it was an object that was useful as illumination because it does not shine during the daytime but would glow at night time.
In the Genroku period book about herbalism, the ''
Honchō Shokkan'', there is a statement about how foxes would use withered trees on the ground to make fires. "Fox fire" in English is translated to "kitsunebi" in Japanese, and this "fox" does not refer to the animal, but instead means "withered" or "rotten and discolored", and seeing how "fox fire" refers to the fire of withered trees and the light of

period ''Kunmō Tenchiben'' by the yomihon author Takai Ranzan and the late Edo Period ''Shōzan Chomon Kishū'' by the essayist Miyoshi Shōzan also state that foxes would hold horse bones in their mouth to light a fire.
In the collection of strange tales from the Nagano Prefecture, the ''Shinshū Hyaku Monogatari'', when a person goes near a kitsunebi, there would be a fox holding human bones in their mouth, and after the fox goes away, the human bone would be glowing a turquoise color.
From things such as this, Enryō Inoue among others support the theory that phosphorous light given off from within bones is linked to kitsunebi.
Phosphorus
spontaneously combusts above 60 degrees, which would also be a reason for why the fox's true identity would be linked to the light from phosphorus.
However, the kitsunebi in legends is said to be visible even from a distance of several kilometers away, which would be hard to square with the idea that they are actually sources of light as weak as hypha or phosphorus.
In 1977, the folkloricist Yoshiharu Tsunda's detailed research gave the explanation that almost all kitsunebi can be explained by a large refraction of light that often occurs in
