If you've ever watched anime or read manga, you've heard them: Naruto-kun, Sakura-chan, Levi-heichou. Japanese honorifics are suffixes attached to the end of names. They aren't just polite filler; they instantly establish the social hierarchy, relationship, and level of intimacy between two speakers.
The Golden Rule
NEVER use an honorific on yourself. You never introduce yourself as "Smith-san." Doing so implies that you consider yourself superior to the listener. When talking about yourself, use your name plain.
The "Big Four" Honorifics
| Honorific | Used For | Nuance & Feeling |
|---|---|---|
| ~San (さん) | Anyone (Men, Women, Strangers) | The default. Equivalent to Mr./Ms. Always safe to use when you don't know someone well. |
| ~Kun (くん) | Boys, Junior male coworkers | Friendly but slightly hierarchical. Used for young men, or by bosses addressing subordinates. |
| ~Chan (ちゃん) | Girls, Babies, Pets, Close friends | Cute and endearing. Using this on a stranger is overly familiar and can be creepy/rude. |
| ~Sama (さま) | Customers, Deities, High-ranking officials | Extremely respectful. Used by shop staff towards you (Okyaku-sama), or in business emails. |
Yobisute (呼び捨て): Dropping the Honorific
What does it mean when a Japanese person calls someone by their name without an honorific attached? This is called Yobisute.
In Japan, this is a massive deal. Dropping the honorific implies extreme closeness—like a spouse, family member, or lifelong best friend. In anime, the moment two characters switch to Yobisute is often used as a dramatic plot point indicating they have fallen in love or formed an unbreakable bond. If you do this with a Japanese coworker, they will be very shocked!
Job Titles as Honorifics
Used for teachers, doctors, and masters of a craft (like manga artists). "Tanaka-sensei" is correct. "Tanaka-san" for a teacher is rude.
Used for someone senior to you at school or work. Can be used alone ("Senpai!") or attached to a name ("Tanaka-senpai").
Used for the Company President. You do not call your CEO "Suzuki-san", you call them "Shachou" or "Suzuki-shachou".
Formal and written: certificates, official notices and internal company memos (田中殿, Tanaka-dono). In speech you mostly hear it in historical dramas. Don't use it for customers; write 様 (sama) instead.
