小札 (Kozatsu) refers to small, decorative notes or cards used in traditional Japanese culture. These notes often feature beautiful calligraphy and are typically made from washi paper. They are commonly used for various purposes, such as expressing gratitude, sending messages, or as part of gift-giving traditions. In the context of Japanese art, 小札 can also be associated with the practice of 書道 (Shodō), or Japanese calligraphy, where the beauty of the written word is emphasized. These notes may be adorned with 和風 (wafū) designs, reflecting the aesthetics of 日本文化 (Japanese culture) and its appreciation for nature and simplicity.
