3. Kasa (hat)A kasa is any of several sorts of traditional hats of Japan. When preceded by a word specifying the type of hat, the word becomes gasa as in the (war hat). One kind of kasa for Buddhist monks is made overly large, in a bowl or mushroom shape and is made from woven rice straw. It does not come to a point like a rice farmer's hat, nor ride high on the head like a samurai's traveling hat. It is just a big hat covering the upper half to two thirds of the face.
