Nengajō are traditional Japanese New Year's greeting cards sent to friends, family, and colleagues. They are typically designed with festive imagery, such as Mount Fuji, cranes, or tigers, depending on the zodiac year. The cards are usually mailed in early December to ensure delivery by January 1st, the start of the new year in Japan. The practice of sending Nengajō dates back to the Edo period and serves as a way to express gratitude and well-wishes for the upcoming year. Many people include personal messages, and it is common to receive a card in return, fostering connections and maintaining relationships throughout the year.
