Quick Answer
Japanese ‘San’ (さん) honorific: What it is: Mr., Mrs., Ms. equivalent + universal honorific used after names. When to use: with everyone you meet — colleagues, strangers, service staff, even family in some contexts. Examples: Tanaka-san (Mr./Ms. Tanaka), sensei-san (teacher), Yamada-san. Honorific hierarchy: -sama (very formal, customers), -san (standard), -kun (junior males/casual), -chan (children, close friends), -sensei (teachers, doctors), -senpai (senior at school/work). For travelers: ALWAYS add -san to Japanese names you address. Never use first names without honorific. Self-reference: NEVER use -san for yourself (humble). Just use given name or surname. Children: -chan for girls + -kun for boys typically. Polite tone: -san + family name (Tanaka-san) more polite than -san + given name (Hiroshi-san — overly familiar). Forgetting -san is RUDE: especially in business/formal contexts.

‘San’ usage rules
- Always with names: Tanaka-san, Yamada-san, Suzuki-san — never just “Tanaka.”
- Strangers + service staff: always -san.
- Colleagues + business contacts: always -san.
- Family of person you\’re talking to: add -san (e.g., “your father-san”).
- Children: often -chan (girls) or -kun (boys) but -san also fine.
- NEVER for yourself: “I am Tanaka” not “I am Tanaka-san.”
- Professional roles: “uketsuke-san” (receptionist) + “tenchou-san” (manager).
- Job/role + san: “isha-san” (doctor) is too informal — use “isha sensei” instead.
- Reading e-mails: sender signs with their name + -san only when speaking about themselves to others.
- Forgetting honorific: very rude, especially in business. Apologize if mistake.
Honorific hierarchy
- -sama (様): very formal — customers, gods, royalty. Used by hotel staff to guests, in formal letters.
- -san (さん): standard polite — universal “Mr./Mrs./Ms.” Use everywhere as travelers.
- -kun (君): junior males — boys, younger male colleagues. Slightly informal.
- -chan (ちゃん): children, close friends + family, pets, cute things. Very informal.
- -sensei (先生): teachers, doctors, lawyers, masters of an art. Higher than -san.
- -senpai (先輩): senior at school/work — student senior to you. NO -san suffix needed.
- -shi (氏): formal written — Mr. in newspapers + documents. NOT spoken.
- -tan (たん): overly cute. Mostly for anime/manga + pet names.
- -shi (師): master craftsman — chef, calligrapher.
- -dono (殿): historical/literary “lord” + still used in formal letters.
- For travelers: -san covers 99% of situations. -sama if addressed by hotel staff.
Examples + situations
- Hotel check-in: reception calls you “Last name-sama” (very polite as customer).
- Calling colleague: “Suzuki-san, ohayou gozaimasu.”
- Asking direction from stranger: “Sumimasen, [name on shop]-san…”
- Tour guide: “Tanaka-san, kore wa nan desu ka?” (Mr. Tanaka, what is this?)
- Restaurant order: not needed when ordering food.
- Restaurant staff: not addressed by name typically.
- Business meeting: always -san after surname.
- Email to Japanese contact: “Dear Suzuki-san” (uses surname + san).
- Family of friend: “Suzuki-san no okaasan” (Mr. Suzuki\’s mother).
- Younger person\’s parent: “Hiroshi-kun no okaasan” — kun for the younger person, -san not needed.
- Doctor: “Sato sensei” — never “Sato sensei-san.”
- Teacher: “Yamada sensei” — same rule, no double honorific.
- Senpai at workplace: “Tanaka-senpai” or just “Senpai.”
Common mistakes by foreigners
- Mistake 1: using -san with first name on first meeting. Use surname + san. First name + san only after explicit “call me by my first name.”
- Mistake 2: using -san for yourself. NEVER. Just “watashi wa Tanaka desu” (I am Tanaka).
- Mistake 3: dropping -san after intimate acquaintance. Even after years, business contexts retain -san.
- Mistake 4: using -chan for adult women. -chan only for children, close friends, family.
- Mistake 5: not realizing -kun is informal. Don\’t use -kun for senior males or strangers.
- Mistake 6: double honorifics. “Tanaka sensei san” — wrong. Choose one.
- Mistake 7: using -shi in conversation. -shi is for written documents only.
- Mistake 8: incomplete pronunciation. “san” not “sang” or “saaaan.” Crisp short “sahn.”
- Mistake 9: using English titles. Don\’t mix “Mr. Tanaka-san” — just “Tanaka-san.”
- Mistake 10: using -sama casually. Reserve for very formal contexts.
Beyond names — non-name honorifics
- Otou-san (お父さん): father.
- Okaa-san (お母さん): mother.
- Onii-san (お兄さん): older brother.
- Onee-san (お姉さん): older sister.
- Obaa-san (おばあさん): grandmother.
- Ojii-san (おじいさん): grandfather.
- Sensei (先生): teacher, doctor, expert.
- Otaku-san (お宅さん): “your household” — very polite address.
- O-san for older woman: casually use o-san before profession. Senior, deserved.
- Common shop names: Sushi-ya san (sushi shop), Yao-ya san (vegetable shop). Older locals use these.
Practical tips for travelers
- Hotel registration: staff will write your name with -sama (most polite).
- Business meetings: exchange business cards (meishi) with bow. Read carefully, then address with -san.
- Travel agent calls: “Tanaka-san?” they\’ll answer.
- Reservations: hotels + restaurants use -san on confirmations.
- Tour groups: guides use -san for everyone in group.
- Polite default: when in doubt, use -san. Safer than no honorific.
- Children\’s names: tour guides + parents use -chan or -kun.
- Apps: Google Translate doesn\’t always add honorifics — learn manually.
- Bow accompaniment: slight bow when addressing -san makes the politeness clear.
- Pronunciation: “sahn” — short crisp. Not “saaaan.”
- If unsure of name: point + say “kore” (this) or “ano kata” (that person) instead.
