Uchiwa is a traditional Japanese hand fan made from a flat piece of paper or cloth attached to a bamboo frame. It is often used during the hot summer months to provide relief from the heat. Uchiwa fans are typically characterized by their round shape and vibrant designs, which can include floral patterns, landscapes, or even popular characters. These fans are commonly seen at festivals, where they are used for cooling and as decorative items. Uchiwa is also associated with Japanese culture and is sometimes given as a gift or used for promotional purposes by businesses during summer events.
