Also known as: 鉢巻, ヘッドバンド, 头带
A strap worn across the forehead, such as a sweatband, a strip of cloth worn during martial arts or athletic events, or a piece of ninja armor (however apocryphal).
While a headband may be used to keep hair out of the eyes, it is usually worn under at least part of the hair. Headbands often end with a long tail trailing behind the head where they are tied.
Not to be confused with Hairband, which is a band worn on top of the head instead of on the forehead, and is used to hold the hair down to maintain a hairstyle.
