Uchiwa is a traditional Japanese hand fan made from a flat piece of paper or cloth stretched over a bamboo frame. It is typically round or oval in shape and is used primarily for cooling oneself during hot weather. Uchiwa fans are often beautifully decorated with colorful designs, making them popular not only for practical use but also as decorative items. These fans are commonly seen during summer festivals and events in Japan, where they are often given as gifts or souvenirs. Unlike sensu, another type of Japanese fan that folds, uchiwa remains open and is easier to use for cooling purposes.
