"Holly sardines", a type of fish decoration, are displayed at entrances during New Year celebrations. It is believed that holly sardines have the power to attract demons, and by affecting the mucous membranes of demons, holly drives away evil spirits and brings good luck for the year. Shiny silver scales are associated with warding off bad luck.

The custom of displaying holly sardines is an event that pays respect to nature and the changing seasons, celebrates the New Year, and prays for health and prosperity in the coming year.
