A yōkai, a supernatural creature who grows taller when a person looks at him, and the higher a person looks, the taller Mikoshi-nyūdō becomes. According the legend, a person who looks too long will die, unless the phrase mikoshita ("I look higher") is uttered, whereupon Mikoshi-nyūdō will disappear.
Mikoshi-nyūdō is often depicted cross-eyed.
