O mark

O mark is the name of the circle symbol "◯".^{[citation needed ]} It is often used in East Asia to express affirmation. Its use is similar to that of the checkmark ("✓") in the Western world. Its opposite is the X mark ("✗" or "×ばつ").

The symbol's names and meanings vary across cultures. In Japanese it is called marujirushi (丸印) or maru (丸) and expresses affirmation. In Korean it is called gongpyo (공표; 空標; lit. ball mark) and expresses affirmation.

Japan interprets the symbol as an affirmation.

Japan employs a number of related symbols (◎にじゅうまる ○しろまる △しろさんかく ×ばつ) in a system that expresses degrees of affirmation. A bullseye "◎にじゅうまる" (nijūmaru; 二重丸) is often used for "excellent", the circle is a plain affirmation, the triangle "△しろさんかく" (sankaku; 三角) means "so-so" or "partially applicable", and the "×ばつ" expresses disagreement. This system is widely known in Japan, and thus often used without explanation. Ad-hoc adjustments are usually explained.

The hanamaru (花丸, 'flower O mark') is a variant of the O mark. 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. It is sometimes used in place of an O mark in grading written response problems if a student's answer is especially good. Some teachers add rotations to the spiral for exceptional answers.

Unicode provides various related symbols, including:

U+2B55 ⭕ HEAVY LARGE CIRCLE has both text and emoji presentations, as shown in the table. It defaults to emoji presentation.

The emoji U+1F4AE 💮 WHITE FLOWER looks similar to hanamaru, although it represents a rubber stamp commonly used to grade students' written answers and is not usually recognized as hanamaru.
