Kiai

Kiai (気合?) /ˈkiː.aɪ/ is a Japanese term used in martial arts. There are numerous examples of the battle cry in other cultures: kiai is perhaps primarily a development of this. In the representation of Asian martial arts in cinema and in animated cartoons, Modern Kiai are often written by westerners in Romaji as Hi-yah!, Aiyah!, Eeee-yah!, or Hyah!. Traditional Japanese Dojo generally use single syllables beginning with a vowel. In the board game Go the term describes fighting spirit.
