In Japanese folklore, the spirits of the dead are referred to as Yūrei. These ethereal beings symbolize the souls of individuals who have not found peace after death, often due to unfinished business or unresolved issues. Yūrei are typically depicted as figures in white funeral garments and are believed to haunt specific locations or people tied to their lives. They reflect deep cultural beliefs about the afterlife and the importance of honoring and respecting deceased loved ones in Japanese traditions.
