Kichō is a Japanese word that means "approval" or "authorization." It's like when you ask your parents for permission to do something, and they say yes or no. Kichō is when someone higher up in authority says yes to something that someone else wants to do. For example, a teacher might give a student kichō to leave the classroom for a minute, or a boss might give kichō to an employee to take a day off from work. It's an important part of Japanese culture to get kichō from people in charge before doing things, to show respect and make sure everything is okay.
