Shugi-bukuro is a traditional Japanese envelope used for gift-giving, particularly during special occasions like weddings, funerals, and other ceremonies. These envelopes are designed to hold monetary gifts, known as shugi, which are given to express congratulations or condolences. Typically made from decorative paper, shugi-bukuro often features intricate designs and may include a ribbon or string to secure the envelope. The presentation is important, as it reflects the giver's respect and thoughtfulness towards the recipient. Proper etiquette dictates specific colors and styles depending on the occasion.
