君・くん (familiar suffix)

• Reading: くん
• Romaji: kun
• Formation: First name / Last name + くん
• Kanji breakdown: 君 — you (familiar), lord; as suffix: familiar address for males/juniors

Meaning

A suffix attached to the first or last name of a male equal or to the first or last name of a younger male, expressing familiarity and a degree of closeness.

くん is most commonly used by teachers addressing male students, by seniors addressing junior male colleagues, or among male friends and classmates. In the workplace, it is used by superiors toward younger male subordinates. While traditionally associated with males, it is increasingly used for women in professional settings, particularly in the Japanese Diet (parliament) and some workplaces where it replaces さん for all subordinates regardless of gender. Unlike さん, which maintains polite distance, くん implies a closer relationship or a clear seniority dynamic. Using くん toward someone older or of higher status is generally considered rude. In anime and manga, くん is a well-known marker of friendly male address.

Examples

1. 田中くん、ちょっと来てくれる。 Tanaka, could you come here for a moment?
2. 健太くんは走るのが速い。 Kenta is fast at running.
3. 鈴木くん、この資料を確認してくれ。 Suzuki, please check this document.
