Japanese Honorifics: San, Kun, Chan, Sama and Beyond

Japanese honorifics (敬称, keishō) are suffixes attached to the end of a person’s name to mark their relationship to you: san, sama, kun, chan, senpai, sensei and a few more. They never stand in front of a name the way Mr. does in English, they attach to family names and given names alike, and leaving one off, called yobisute (呼び捨て), is itself a statement.

Japanese Honorifics List: Every Common Suffix at a Glance

Each row is a complete answer: the suffix, how it is written, its closest English equivalent, who receives it, and how formal it sounds.

If you learn one row, learn the first. Family name plus san is almost never wrong and is never insulting.

What Does San (さん) Mean?

San (さん) is the standard Japanese honorific, roughly Mr., Ms. or Mrs., but neutral for gender, age and marital status. It attaches to family names, given names, company names and even trades. Polite without being stiff, it is the correct default for strangers, colleagues and anyone whose position you have not yet worked out.

• 田中さん (Tanaka-san): the colleague two desks over, on your first day and on your thousandth.
• 佐藤さん (Satō-san): a client’s representative you have just met, said as you take her card with both hands.
• 美咲さん (Misaki-san): a friend’s partner whose given name you have been offered, but not yet the license to drop the suffix.

When not to use san: never on your own name. Watashi wa Sumisu-san desu means “I am the honorable Mr. Smith.” Say Sumisu desu. Never stack it on a title that already outranks it either: Itō-sensei, not Itō-sensei-san.

San is also the most elastic suffix in the language. The fish seller is sakana-ya-san. The bookshop is hon-ya-san. A supplier talking about a client company will say Sony-san without blinking. In a Kansai children’s story a sweet potato can be o-imo-san, roughly “honorable Mr. Potato,” which tells you how affectionately loose the thing can get.

What Does Sama (様) Mean?

Sama (様) is san raised several floors, the honorific for anyone the speaker places distinctly above themselves. It belongs to customers, deities and addressed envelopes. In everyday conversation it is either service-industry formality or deliberate sarcasm. There is no casual sama.

• 山本様 (Yamamoto-sama): written on an envelope or a parcel label, the one place sama is genuinely routine.
• 鈴木様 (Suzuki-sama): a hotel guest, said by the front desk clerk reading the reservation aloud.
• 渡辺様 (Watanabe-sama): a client’s managing director, addressed at the top of a formal quotation letter.

When not to use sama: never on a colleague. Tanaka-sama said across a shared desk reads as sarcasm, and Japanese speakers deploy it exactly that way when they want to tease somebody for acting grand.

Sama is the load-bearing beam of Japanese service culture. Every shop greeting contains okyaku-sama (お客様), the honored customer, which is where honorifics meet omotenashi. Gods are kami-sama (神様). The phrase o-tsukare-sama desu, said to someone finishing work, literally honors their tiredness.

What Does Kun (君) Mean?

Kun (君, くん) is the honorific for boys and junior men, warm and faintly downward-looking. Teachers use it on male students, managers on young male staff. It quietly assumes the speaker holds the senior position, which is why the direction of travel matters more than gender does.

• 鈴木くん (Suzuki-kun): a homeroom teacher taking attendance in a middle school classroom.
• 渡辺くん (Watanabe-kun): a section chief thanking a second-year employee for a report.
• 山本くん (Yamamoto-kun): a member of the National Diet, where the chair addresses every member with kun regardless of gender.

When not to use kun: never upward. A junior calling a senior kun is a real offense rather than a slip, because it claims a seniority the speaker does not have. It reads as presumptuous at best and mocking at worst.

The Diet case is the useful one to remember, because it shows kun is not a male suffix with exceptions. It is a downward suffix that most often lands on boys. Senior colleagues in older institutions still address women as kun for the same reason.

What Does Chan (ちゃん) Mean?

Chan (ちゃん) is the affectionate Japanese honorific, a soft childlike slurring of san that never lost its softness. Small children, close friends, grandparents, pets and corporate mascots all get chan. It claims intimacy or cuteness, and claims are not always welcome.

• ゆきちゃん (Yuki-chan): a best friend since primary school, still used by both of them at forty.
• たかちゃん (Taka-chan): a nickname carved out of the family name Takahashi by the people who grew up next door.
• 美咲ちゃん (Misaki-chan): a six-year-old at a family gathering, said by an aunt who has known her since birth.

When not to use chan: never with a superior, and never with an adult you barely know. Aimed at a woman in a professional setting by a man who met her ten minutes ago, chan reads as “I do not take you entirely seriously.”

Chan drives most Japanese nicknames because it prefers short stems. Takahashi becomes Taka-chan. Yuriko becomes Yuri-chan, then Yun-chan. The name gets shorter as the relationship gets closer, which makes the suffix a fairly reliable instrument for measuring how close two people actually are.

San vs Sama vs Kun vs Chan: Which Japanese Honorific to Use

The four most common Japanese honorifics differ on two questions: how far above you the other person sits, and how close you are to them. San is the neutral middle. Sama moves up. Kun moves down. Chan moves sideways into closeness.

Two rules cover almost every mistake. Never point kun or chan upward, and never point sama sideways. If you cannot place someone, san is correct and costs you nothing.

What Does Senpai (先輩) Mean?

Senpai (先輩) is the Japanese honorific for the person who entered before you: the third-year to your second-year, the colleague with five years to your five days. It works both as a suffix on a name and as a standalone form of address, which almost no other honorific does.

• 山本先輩 (Yamamoto-senpai): a second-year addressing the club captain in the corridor.
• 田中先輩 (Tanaka-senpai): a new hire speaking to the colleague who trained her, still using it three years later.
• 先輩 (senpai): called across a room with no name attached at all, which san can never do.

When not to use senpai: not for someone senior in rank but junior in tenure. Senpai tracks arrival order, not the org chart, so a manager hired last year is not the senpai of a clerk who arrived a decade ago.

Senpai is the only item on this list that names a complete relationship rather than a level of politeness. Obligations run in both directions. The senpai teaches, covers, and pays for dinner. The kōhai defers, arrives early, and carries things.

What Does Kohai (後輩) Mean?

Kōhai (後輩), often written kohai in English, is the junior half of the senpai relationship: the person who joined your school, club or company after you did. It is the one term on this list of Japanese honorifics that is never used as a suffix on a name and never used to address anybody.

• 佐藤さん (Satō-san): what you actually call your kōhai to his face, because kōhai is not a form of address.
• 「僕の後輩です」 (boku no kōhai desu): “he is my kōhai,” said about him to a third person, which is the correct use.

When not to use kōhai: never as Satō-kōhai. Attaching kōhai to a name is like introducing a colleague at a party as “my subordinate.” Kōhai is a word you use about a relationship, in the third person, not to the person themselves.

This is the single most common error in English-language guides to Japanese honorifics, and it travels because the senpai and kōhai pair looks symmetrical in a table. It is not. Only one half of it is a suffix.

What Does Sensei (先生) Mean?

Sensei (先生) is the Japanese honorific for teachers and masters, and it literally means “born before.” It goes to teachers, doctors, lawyers, published authors, martial arts instructors and politicians, and it replaces san completely rather than sitting alongside it. Like senpai, it also stands alone as a form of address.

• 佐藤先生 (Satō-sensei): the family doctor, aged twenty-eight, addressed by a patient of seventy.
• 渡辺先生 (Watanabe-sensei): a calligraphy teacher, greeted at the door of the studio.
• 田中先生 (Tanaka-sensei): a novelist, addressed by an editor who has never taken a class in her life.

When not to use sensei: never stacked. Itō-sensei-san and sensei-sama are both wrong, because sensei already carries the respect. Never on yourself, either. Describing your own job, you are a kyōshi (教師), a teacher.

Sensei rests on acquired expertise rather than arrival order, which is why the twenty-eight-year-old physician outranks the seventy-year-old patient without anyone in the room finding it strange.

What Does Dono (殿) Mean?

Dono (殿) is an archaic Japanese honorific that historically sat between san and sama, the address for a lord or a warrior of standing. Today it survives almost entirely in writing: certificates, award texts, internal notices and formal documents issued downward from management. In speech it belongs to period drama.

• 田中殿 (Tanaka-dono): a name printed on a certificate of commendation.
• 山本殿 (Yamamoto-dono): an internal notice sent from head office to a branch manager at a traditional firm.
• 鈴木殿 (Suzuki-dono): a retainer addressing a samurai on screen, which is where most people meet the word.

When not to use dono: not in a modern email to a client or a senior. Dono is issued downward, so pointing it upward is a genuine error, and pointing it sideways lands as archaic or faintly mocking. Sama is the safe replacement.

Even inside the companies that still use it, dono is thinning out. Younger staff read it as stiff. If you receive one, it almost certainly came from a template written in the 1980s.

What Does Shi (氏) Mean?

Shi (氏) is the honorific of print. Newspapers, legal filings, academic papers and broadcast news use it after a family name to refer to a third party, usually an adult the writer has never met. It carries respect at a polite distance, and it almost never appears in conversation.

• 田中氏 (Tanaka-shi): a newspaper sentence reporting what a company president said at a press conference.
• 渡辺氏 (Watanabe-shi): an academic paper citing a researcher’s stated position.
• 山本氏 (Yamamoto-shi): a news anchor reading a script, one of the few places shi is spoken aloud.

When not to use shi: not to somebody’s face. Saying Yamamoto-shi to Yamamoto sounds like reading a document out loud in front of him. Speak, and use san.

Shi has one convenient property. Once the full name has appeared, shi can carry on alone for the rest of the article, as long as only one person is in play. English does the same trick with a bare surname.

What Do Tan (たん) and Chin (ちん) Mean?

Tan (たん) and chin (ちん) are the cutesy Japanese honorifics, chan pushed further into baby talk by deliberate mispronunciations that imitate a toddler mangling the suffix. They live in mascot names, fan nicknames and very close friendships. None of them are neutral. Each one is a small performance of cuteness.

• ゆきたん (Yuki-tan): a fan nickname for a character, written online far more often than it is spoken.
• 美咲ちん (Misaki-chin): two friends in their teens, one of whom invented it and made it stick.
• 田中さん (Tanaka-san): what those same friends switch back to the second a teacher walks in.

When not to use tan or chin: never at work, and never on somebody who did not choose the nickname. Using tan on a coworker is not a small politeness error. It is a genuinely strange thing to do.

Other one-off inventions circulate too: pyon, bee, and whatever a particular friend group decided was funny. They are marked, performative, and tied to a subculture. Treat them as vocabulary to recognize rather than vocabulary to use.

What Do Bucho, Kacho and Shacho Mean?

Buchō (部長), kachō (課長) and shachō (社長) are Japanese job titles that work as honorifics: department head, section head and company president. In a Japanese office you address a superior by their post rather than by name plus san. Each works as a standalone address and as a suffix, and each replaces san rather than joining it.

• 田中課長 (Tanaka-kachō): the section head, named because two section heads are in the room at once.
• 山本社長 (Yamamoto-shachō): the company president, named while introducing him to a visiting client.
• 部長 (buchō): the department head addressed with no name at all, which a job title allows and san does not.

When not to use a job title: never add san on top. Tanaka-kachō-san is a beginner’s error, because the title already outranks san. And do not use the title when speaking about your own boss to an outside client, where humility rules turn your president into plain Yamamoto, no honorific attached.

That last rule catches almost every foreigner once. Inside the building, the section chief is kachō. On the phone to a customer, the same man is bare-name Tanaka, because your group gets humbled and theirs gets raised. It is the same instinct that governs meishi kokan, the business card exchange, where the whole ritual is a negotiation over who is positioned where.

What Does Yobisute (呼び捨て) Mean?

Yobisute (呼び捨て) means “calling and discarding”: using a bare name with no Japanese honorific attached at all. It is never neutral, and its meaning flips entirely depending on direction and relationship.

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 identical 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 track. 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.

Why Japanese Has Honorifics

Japanese honorifics exist because the language does its social positioning at the end of a name rather than the front. English says Mr. Tanaka, Doctor Itō, Professor Yamada. Japanese says Tanaka-san, Itō-sensei, Yamada-sensei, and it does this nearly every time a name is spoken aloud.

That positioning 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.”

Japanese Honorifics: Family Name or Given Name?

Japanese honorifics attach to family names by default, not given names. 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, and people notice when one is skipped.

Japanese Honorifics in Anime vs Real Japanese

Anime is honorific-dense and honorific-dramatic, and that is a writing decision rather than a documentary one. Real conversation refers to people by name far less often than anime does. Japanese drops subjects happily, 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 of fifteen.

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 can spit baka at someone and have the audience read it as affection. The same exaggeration applies to stock phrases: ara ara is an ordinary mild interjection in real Japanese, closer to “oh my,” and a whole character type on screen. Nicknames carry the charge in reverse: in My Hero Academia, deku starts as a bully’s pun on a name and finishes as a hero’s title.

Then there is subtitling. Translators either keep the suffixes, which reads as slightly exotic in English, or drop them, which quietly deletes information about the relationship. Both choices lose something, which is why so many fan translations leave 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.

Common Japanese Honorific Mistakes

Calling yourself san. Never attach an honorific to your own name. Watashi wa Sumisu-san desu means “I am the honorable Mr. Smith.” Say Sumisu desu.

Elevating your own family to outsiders. Speaking to someone outside your household, your own mother is haha (母), not okā-san. Your group gets humbled, theirs gets raised. Inside the house, okā-san is exactly right.

Sliding sama into casual talk. It reads as either fawning or sarcastic, with nothing in between.

Stacking honorifics. Sensei-san. Tanaka-san-sama. Kachō-san. 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 in the room.

Using kōhai 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.

Japanese Honorifics and Keigo

Honorifics are the visible tip of a much larger system. Keigo (敬語), honorific language, is the grammar surrounding them, and it runs in three registers: sonkeigo (尊敬語), which exalts the other person’s actions, kenjōgo (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 instantly, 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 the whole sentence, the same dial that governs the set expressions collected in our guide to Japanese phrases with deep meaning.

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 san and sama?

San (さん) is everyday politeness and sama (様) is elevated respect, several steps higher. San suits colleagues, neighbors and strangers. Sama belongs to customers (okyaku-sama), gods (kami-sama) and names written on mail. Using sama with a colleague in conversation sounds sarcastic, so learners should keep it to written addresses and set service phrases.

What is the difference between kun and chan?

Kun (君, くん) marks juniority and goes mostly to boys, junior men and students, spoken by someone senior to them. Chan (ちゃん) marks affection and closeness, and goes to small children, close friends, grandparents and pets regardless of gender. Kun is about rank, chan is about intimacy, and neither should ever be aimed at a superior.

What does senpai mean?

Senpai (先輩) is the Japanese term for someone who joined your school, club or company before you did. It is used both as a suffix on a name, as in Yamamoto-senpai, and on its own as a form of address. It tracks arrival order rather than the org chart, and it carries real obligations: the senpai teaches, covers and pays.

Can you use chan with an adult?

Yes, but only with someone genuinely close: an old friend, a partner, a grandparent, a sibling. Chan (ちゃん) claims intimacy, so using it on an adult you barely know, especially a woman in a professional setting, comes across as condescending rather than friendly. With any adult senior to you, it is simply wrong. Use san.

What does kun mean?

Kun (君, くん) is the honorific for boys and junior men, warm but slightly downward-looking. Teachers use it on male students and managers on young male staff. It is not strictly gendered: in Japan’s National Diet, the chair addresses every member with kun. A junior must never use kun toward a senior.

Do you use honorifics with your own name?

No. 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 the bare name plus desu, and refer to relatives with humble forms: haha for my mother, chichi for my father, ani for my older brother.

What happens if you use the wrong honorific?

Usually very little. Japanese speakers expect learners to slip and will quietly forgive it. The exceptions are directional errors: kun or chan aimed at a senior, sama aimed at a colleague, or a bare name aimed at someone who has not invited it. Those land as disrespect rather than as a language mistake.
