家紋 (kamon) are traditional Japanese family crests that symbolize a family's identity and heritage. These unique designs often feature stylized plants, animals, or geometric shapes, and they are used in various contexts, such as on clothing, banners, and gravestones. Each 家紋 is distinct, representing the lineage and history of a particular family. The use of 家紋 dates back to the Heian period (794-1185) and became more prominent during the 戦国時代 (Sengoku period). They served as a way to identify samurai and noble families in battle and during ceremonies. Today, 家紋 continue to hold cultural significance, often displayed during weddings and other important family events.
