Japanese honorifics (敬称, keishou, literally “respectful names”) are the small suffixes attached to a person’s name to mark their relationship to you: san, sama, kun, chan, and a handful of others. Say a coworker’s name bare, with nothing on the end, and everyone in the room hears the omission the way English speakers hear a first name used at a funeral.
Why Japanese Needs Honorifics
English does its social positioning at the front of a name. Mr. Tanaka. Doctor Ito. Professor Yamada. Japanese does the same work at the back of the name, and it does it constantly. Nearly every time you say someone’s name out loud in Japanese, you are also saying something about the distance between the two of you.
That distance runs along two axes. The vertical axis is rank: who is older, who joined first, who is serving whom. The horizontal axis is closeness, including whether the person belongs to your group (uchi 内) or to someone else’s (soto 外). An honorific is the tiny piece of grammar where those two axes cross.
I once watched a new hire at a Tokyo publishing house go almost three full days without saying a single colleague’s name out loud. He was not shy. He was collecting data. Who does the section chief call by family name plus san? Who gets kun? Who does the whole floor call by a nickname, and who never does? By Thursday morning he had the map, and I never once heard him get it wrong.
“An honorific is not decoration on a name. It is the sentence you speak before the sentence.”
The good news for learners is that the system has a safe default and a small number of common pieces. The rest is nuance you pick up by listening.
The Honorifics, One by One
San (さん)
San さん is the workhorse. It attaches to family names, given names, company names, and even occupations, and it means something close to “the respected.” Tanaka-san. Yamada-san. Sony-san, if you are a supplier talking about a client company.
San is polite without being stiff. It is safe with strangers, safe with colleagues, safe with the woman who runs the bakery on your corner. It is neutral for gender and flexible for age: a six-year-old can be Kenta-san if the speaker wants a note of formality or of gentle, mannered warmth.
It also travels onto things and trades. The fish seller is sakana-ya-san. The bookshop is hon-ya-san. In Kansai, a sweet potato in a child’s story might be o-imo-san, roughly “honorable Mr. Potato,” which tells you how affectionately loose the suffix can get. If you learn exactly one honorific in your life, learn this one.
Sama (様)
Sama 様 is san raised several floors. It belongs to customers, deities, addressed envelopes, and anyone the speaker is placing distinctly above themselves.
Every piece of mail in Japan is addressed to a name plus sama. Every shop greeting contains okyaku-sama (お客様), the honored customer, which is the load-bearing beam of Japanese service culture and of omotenashi. Gods are kami-sama (神様). The set phrase o-tsukare-sama desu, said to someone finishing work, literally honors their tiredness.
What you almost never do is use sama in casual spoken conversation with the person in front of you, unless you are on duty and they are the customer. Drop a sama into a chat with a friend and it lands as sarcasm, which is exactly how Japanese speakers use it when they want to tease someone for acting grand.
Kun (君)
Kun 君 goes to boys and to junior men. A teacher calling on a student: Suzuki-kun. A manager addressing a young male employee: Nakamura-kun. It is warm, faintly downward-looking, and it quietly assumes the speaker holds the senior position.
Two things surprise learners. First, kun is not strictly male. Senior colleagues sometimes address women as kun in older or more traditional institutions, and in the National Diet every member is addressed with kun regardless of gender. Second, the direction matters enormously. A junior should not call a senior kun. It reads as presumptuous at best and mocking at worst.
Chan (ちゃん)
Chan ちゃん is the sound of affection. It began life as a soft, childlike slurring of san, and it never lost that quality. Small children, close friends, grandparents, pets, and corporate mascots all get chan. Obaa-chan for grandma. Yuki-chan for a best friend since primary school. Wan-chan for a dog.
Chan also drives most Japanese nicknames, because it prefers short stems. Takahashi becomes Taka-chan. Yuriko becomes Yuri-chan or even Yun-chan. The name gets shorter as the relationship gets closer.
The thing to hold onto is that chan claims intimacy or cuteness, and claims are not always welcome. Used on an adult you barely know, especially a woman in a professional setting, it can read as “I do not take you entirely seriously.” Same suffix, completely different temperature, depending on who is allowed to use it.
Senpai (先輩)
Senpai 先輩 means the person who entered before you: the third-year student to your second-year, the colleague with five years to your five days, the black belt who was already in the dojo when you arrived.
Senpai behaves differently from san, kun, and chan in one important way. It works as a suffix (Yamada-senpai) and also as a standalone word you can use in place of a name, calling across a room simply “senpai.” It is also the only item on this list that names a complete relationship with obligations running in both directions, not just a level of politeness.
Kouhai (後輩)
Kouhai 後輩 is the mirror term, the one who came after. Here is the trap almost every learner falls into: kouhai is not used as an honorific. Calling someone Tanaka-kouhai to their face is like introducing a colleague at a party as “my subordinate.”
Kouhai is a word you use about a relationship, usually in the third person. “He is my kouhai from the tennis club.” To the person themselves, you use their name plus san, kun, or chan.
Sensei (先生)
Sensei 先生 literally means “born before.” It goes to teachers, doctors, lawyers, published authors, martial arts instructors, and politicians. It replaces san completely: Ito-sensei, never Ito-san-sensei.
Like senpai, sensei stands alone as a form of address. Unlike senpai, it rests on acquired expertise rather than on arrival order, which is why a twenty-four-year-old physician is sensei to a seventy-year-old patient without anyone finding it odd.
Shi (氏)
Shi 氏 lives almost entirely in print. Newspapers, academic writing, and formal reports use it after a family name to refer to a third party with neutral respect: Tanaka-shi stated in the interview. You will rarely hear it in conversation, and when you do, the speaker is usually reading from a document or performing a very particular kind of formality.
Dono (殿)
Dono 殿 historically sat between san and sama, the address for a lord or a warrior of standing. That is why period dramas and samurai anime use it constantly, and why using it in a modern living room is a joke.
It has one surviving foothold: internal business documents, certificates, and award texts sometimes still place dono after a name or a job title. Written, formal, slightly stiff, and entirely dead in speech.
Tan, Chin, and the Playful Fringe
Past the standard set sit deliberate cute distortions. Tan たん is chan pushed further into baby talk, a fixture of mascot names and of fan affection for a character. Chin ちん works much the same way. Pyon, bee, and various one-off inventions circulate inside fan communities and among close friends.
None of these are neutral. They are marked, performative, and tied to specific subcultures. Using tan for a coworker is not a small politeness error, it is a genuinely strange thing to do.
Family Names, Given Names, and What the Switch Means
In English-speaking offices, moving to a first name is the low-stakes, friendly move that happens in the first ten minutes. In Japan it is the opposite. Family name plus san is the standard for colleagues who have worked side by side for a decade, and it is not cold. It is simply the default setting.
Given names come out inside families, among school friends, between couples, and in workplaces that have deliberately adopted a flat culture. When someone offers you their given name, they are opening a door. Walking through it uninvited is the awkward move.
The pattern to watch is the combination. Family name plus san is neutral. Given name plus san is warm but still mannered. Given name plus chan is close. Given name alone is intimate. Each step is a real step.
Yobisute: Dropping the Honorific on Purpose
Yobisute (呼び捨て) means “calling and discarding,” using a bare name with nothing attached. It is never neutral, and its meaning flips depending on direction.
Downward, yobisute is authority. A coach barking a surname across a field, a parent using a child’s given name, an old-school manager addressing staff. Sideways with a stranger or upward toward a senior, the same bare name is rudeness that edges into aggression. Between close friends, siblings, and partners, it is intimacy, and arriving there is a small milestone people actually notice. Couples sometimes date their relationship by it: the evening one of them dropped the chan.
Fiction uses this beautifully. A character who has said Yamada-san for twenty episodes and then says only Yamada has confessed something without confessing anything. Nicknames can carry the same charge in reverse, starting as a wound and ending as a badge. In My Hero Academia, deku begins as a bully’s pun on a name and finishes as a hero’s title.
Honorifics in Anime Versus Honorifics in Life
Anime is honorific-dense and honorific-dramatic, and that is a writing decision rather than a documentary one.
Real Japanese conversation refers to people by name far less often than anime does. The language happily drops subjects, so two colleagues can talk for ten minutes without either name surfacing once. Anime keeps saying names because the audience needs to keep track of a cast.
Anime also loads suffixes for characterization. A single kun from a normally frosty character is a plot event. Archetype comedy runs on the gap between what a character says and what they mean, which is why a tsundere character can spit baka at someone and have the audience read it as affection. That is real emotional logic, sharpened for the screen.
Then there is subtitling. Translators either keep the suffixes, which reads as slightly exotic to English audiences, or drop them, which quietly deletes information about the relationship. Both choices lose something, which is why so many fan translations keep san and senpai untranslated.
The practical upshot: anime is a good place to hear honorifics used with intent, and a bad place to calibrate how often to use them.
Mistakes Foreign Speakers Make Most Often
Calling yourself san. Never attach an honorific to your own name. “Watashi wa Smith-san desu” means “I am the honorable Mr. Smith.” Say Smith desu.
Elevating your own family to outsiders. Speaking to someone outside your household, your own mother is haha (母), not okaa-san. Your group gets humbled, theirs gets raised. Inside the house, okaa-san is exactly right.
Sliding sama into casual talk. It will read as either fawning or sarcastic. There is no casual sama.
Stacking honorifics. Sensei-san. Tanaka-san-sama. One per name, always.
Using kun or chan upward. Not to a boss, not to a senior, not to a client, no matter how friendly the mood.
Using kouhai as a suffix. Covered above, and worth repeating because it appears in so many English-language guides.
Assuming given names signal warmth. In Japan the given name is the forward move, not the friendly one. Default to family name plus san and let the other person set the pace.
Over-correcting on invitation. When a Japanese friend says “you do not have to be so formal with me,” they usually mean relax the verb endings. The name suffix often stays. Wait for a clearer signal, or ask directly, which is a completely acceptable thing to do.
When you are genuinely unsure: family name plus san. It is almost never wrong, and it is never insulting.
Where Honorifics Sit Inside Keigo
Honorifics are the visible tip of a much larger system. Keigo (敬語), honorific language, is the grammar surrounding them, and it has three registers: sonkeigo (尊敬語), which exalts the other person’s actions, kenjougo (謙譲語), which humbles your own, and teineigo (丁寧語), the plain politeness carried by desu and masu.
Suffix and grammar have to agree. Tanaka-sama followed by blunt casual verb endings is a mismatch a Japanese listener hears immediately, like a tuxedo worn with flip-flops. This is the real reason honorifics feel hard: they are not vocabulary items, they are one visible setting on a dial that adjusts your whole sentence.
Under all of it sits wa (和), harmony. The point of the system is not hierarchy for its own sake. It is keeping friction out of the room by making everyone’s position clear before anyone has to negotiate it. When the suffix is right, nobody notices it, and that invisibility is precisely the goal.
FAQ
What does san mean in Japanese?
San (さん) is the standard, all-purpose Japanese honorific, roughly equivalent to Mr., Ms., or Mrs., but neutral for gender, age, and marital status. It attaches to family names, given names, company names, and even shop trades. It is polite without being formal, and it is the correct default for strangers, colleagues, and acquaintances.
What is the difference between kun and chan?
Kun (君) is used for boys and junior men, carrying a warm but slightly senior tone, common from teachers and managers. Chan (ちゃん) signals affection or cuteness and goes to small children, close friends, grandparents, and pets, regardless of gender. Kun leans toward mild seniority, chan leans toward intimacy. Neither should be used toward someone above you.
What does sama mean?
Sama (様) is a high-respect honorific, several steps above san. It is used for customers (okyaku-sama), gods (kami-sama), on addressed mail, and for anyone the speaker places distinctly above themselves. In ordinary spoken conversation it is either service-industry formality or deliberate sarcasm, so learners should avoid it outside set phrases and written addresses.
Is it rude not to use honorifics in Japanese?
Usually, yes. Using a bare name is called yobisute (呼び捨て), and toward a stranger, a senior, or a colleague it reads as rude or aggressive. It is appropriate only downward (a coach to a player, a parent to a child) or between people who are genuinely close. Family name plus san is the safe choice.
What honorific do you use for yourself?
None. You never attach san, sama, or any other honorific to your own name, and you do not use them for your own family when speaking to outsiders. Introduce yourself with your bare name plus desu, and refer to your own relatives with the humble forms: haha for my mother, chichi for my father, ani for my older brother.
