In Japan, the tradition of “大掃除” (Ōsōji), meaning “big cleaning,” takes place at the end of the year. This cultural practice involves a thorough cleaning of homes, workplaces, and public spaces to bid farewell to the old year and welcome the new one with a fresh start. Families engage in deep cleaning, decluttering, and organizing to symbolize leaving behind the past and preparing for a clean slate in the coming year. It is a shared activity that fosters a sense of renewal and harmony within the family, work colleagues and community.
