An O mark, also known as Marujirushi (丸印) in Japan, Gongpyo (공표, 공標, ball mark) in Korea and Quanhao (Chinese: 圈號) in Taiwan, is the name of the symbol "⭕" used to represent affirmation in East Asia, similar to its Western equivalent of the checkmark. Its opposite is the X mark ("✗") or ("×").
The hanamaru (花丸) is a variant of the O mark used in Japan, written as 💮. It is typically drawn as a spiral surrounded by rounded flower petals, suggesting a flower. It is frequently used in praising or complimenting children, and the motif often appears in children's characters and logos.
The hanamaru is frequently written on tests if a student has achieved full marks or an otherwise outstanding result. Sometimes used in place of an O mark in grading written response problems if a student's answer is especially good. Some teachers will add more rotations to the spiral the better the answer is. It is also used as a symbol for good weather.
