Nengajo are traditional Japanese New Year greeting cards sent to friends and family. These cards are typically designed with festive images, such as Mount Fuji, cherry blossoms, or the Chinese zodiac animal of the year. People write messages wishing happiness and good fortune for the upcoming year. In Japan, it is customary to send nengajo before January 1st, so they arrive on New Year's Day. The practice reflects the importance of maintaining connections and expressing good wishes. Many people enjoy creating or selecting unique designs to share their sentiments during this special time.
