A Japanese fan, known as a "uchiwa" or "sensu," is a traditional folding or non-folding hand-held fan used in Japan. Uchiwa fans are typically made from a flat surface of paper or cloth attached to a bamboo frame, while sensu fans are made of multiple folded sections that can be opened and closed. These fans are often beautifully decorated with intricate designs, reflecting Japanese art and culture. Japanese fans serve both practical and aesthetic purposes. They are used to cool oneself during hot weather and are also popular in traditional performances, such as Kabuki and Noh. Additionally, fans are often given as gifts or used in ceremonies, symbolizing good fortune and hospitality.
