The kitsune no yomeiri is a term or metaphor for certain natural phenomena, or a folk belief regarding a supernatural event, in Honshu, Shikoku, and Kyushu. The term "kitsune no yomeiri" can refer to several things: atmospheric ghost lights, in which it appears as if paper lanterns from a wedding procession are floating through the dark; sunshowers; or various other phenomena that may resemble wedding processions and are referenced in classical Japanese kaidan, essays, and legends. The kitsune no yomeiri is always closely related to foxes, or kitsune, who often play tricks on humans in Japanese legend; various Shinto rituals and festive rites relating to the kitsune no yomeiri have been developed in various parts of Japan.

A sunshower, or sun shower, is a meteorological phenomenon in which rain falls while the sun is shining. A sunshower is usually a result of winds associated with a rain storm sometimes miles away, blowing the airborne raindrops into an area where there are no clouds. Sometimes a sunshower is created when a single rain shower cloud passes overhead, and the sun's angle keeps the sunlight from being obstructed by overhead clouds.
