In the mountainous regions of Kōchi Prefecture and Tokushima Prefecture among other areas of West Japan, encountering such a strange event is called "being cut by a nogama (, "wild sickle")," and they are said to be the deeds of grass-cutting sickles that have been left and forgotten on fields and have ended up turning into yōkai, and they are also said to be a sickle's vengeful spirit (onryō) that has turned it into a tsukumogami (a receptacle that has turned into yōkai). In the Iya region, Tokushima Prefecture, it is said that sickles and hoes used for digging the hole in a funeral, if left for 7 days without taking it back, would turn into a nogama, and when one encounters a nogama, it is said that one should chant, "beneath the feet on the bottom-left of Buddha, is the stump of a kurotake species of bamboo, and quickly became clean, but let it grow back (hotoke no hidari no shita no omiashi no shita no, kurotake no kirikabu nari, itau wa nakare, hayaku routa ga, haekisaru)."
