Mikoshi-nyūdō

In Japanese folklore and Edo period (1603–1868) kaidan "ghost story" texts, mikoshi-nyūdō will frighten people who look over the top of things such as byōbu folding screens.

[3] It is said that getting flown over by a mikoshi-nyūdō results in death or getting strangled by the throat, and if one falls back due to looking up at the nyūdō, one's windpipe would get gnawed at and killed.

[8] In the essay Enka Kidan (煙霞綺談) by Hakuchō Nishimura from the Edo period, the mikoshi-nyūdō is a yakubyōgami that inflicts people with fever, and there is a story as follows: In the Shōtoku era, in Yoshida, Mikawa Province (now Toyohashi, Aichi Prefecture), the merchant Zen'emon, while on the way to Denma in Nagoya, encountered a whirlwind, and the horse he rode on started to have its feet hurt, and when Zen'emon also felt unwell and started crouching, an ōnyūdō with a height of about one to and three or four shaku (about four meters) appeared.

Afterward, Zen'emon reached his destination of Nagoya, but he lost his appetite, was afflicted by a fever, and even medical treatment and drugs had no effect, and died on the 13th day.

[1][9]In a certain region of the Okayama Prefecture, if a female squats at a toilet, a fox (kitsune) shapeshifted into a mikoshi-nyūdō would appear and say menacingly, "Wipe your butt?

[1] Yōkai similar to the mikoshi-nyūdō, such as the shidaidaka, the taka-nyūdō, the taka-bōzu, the nobiagari, the norikoshi-nyūdō, the miage-nyūdō, the nyūdō-bōzu, the yanbon, etc.

In Kamikawane, there is a story where in the past, two young fellows discovered nobori-like object climbing up the night sky, and were surprised, saying "It's a mikoshi!

[9][17] The mikoshi-nyūdō that has been depicted under the title "Mikoshi" in the Gazu Hyakki Yagyō by Sekien Toriyama (refer to image) is depicted covered by the shadow of a large tree, and its neck has become long, but since this is its appearance to people looking from behind, it does not mean that it is emphasizing the length of its neck like that of a rokurokubi.

[18][19] There is the opinion that these kinds of things give a glimpse on the varied and complicated influences that went into forming the world of yōkai.
