Kasa (hat)

A kasa (笠) is any one of several traditional Japanese hats.

Kasa is the correct way to pronounce the word when it stands alone.

Rendaku causes kasa to change to -gasa when it is preceded by another word specifying the type of hat, as in jingasa.

Kasa shares its etymology with the Japanese word for "umbrella" (also pronounced kasa, but written as 傘).

Varieties of kasa were used throughout most all levels of Japanese society.
