-san, -chan, -sensei: Getting Someone's Name Right in Japan

Honorifics aren't decoration — they encode who's inside your circle and who's outside it. Four naming mistakes visitors make constantly, and the safe default that gets you through almost every situation.

Putting -san on your own name

Introducing yourself as 'Smith-san' or signing off an email that way

It's the single most common honorific error visitors make, and it's an easy one to fall into — you hear -san attached to every name around you and assume it's simply part of how names are said. It isn't. Honorifics are things you extend to other people; hanging one on yourself has the flavour of introducing yourself as 'the honourable Mr Smith.' Nobody will correct you, which is exactly why people keep doing it for years.

Bare name for yourself — and for your own side, too

Say 'Smith desu.' The same humility rule extends outward in a way that surprises people: when you're talking to someone outside your group about someone inside it, the honorific comes off there as well. Telling a client about your own boss, you say 'Tanaka will be there' — no -san, no title — even though you'd never address him that way to his face. Your family works the same way when you mention them to outsiders. Inside the group, honorifics; across the line to the outside, humility. 🗣️

Jumping straight to first names

Calling a new colleague 'Yuki' the day you meet her

In much of the world, moving to first names quickly is friendliness. In Japan it lands as forwardness, especially at work, and it can put the other person in the awkward position of either reciprocating a closeness they don't feel or visibly not reciprocating. It's worth knowing that a Japanese person introducing themselves to a foreigner will often lead with their given name to make things easier for you — which is a kindness, not an invitation to drop the honorific.

Family name + san is the default that never misfires

Tanaka-san. That's the setting you can leave on for essentially everyone: colleagues, shopkeepers, your host, someone twice your age, someone half it. Given name + san (Yuki-san) shows up among younger people, in casual circles, and where two people share a surname — and it's fine once you've heard others in the room use it. The reliable method is simply to copy how the person is addressed by everyone else, and to keep the -san even after you've switched to their given name. 🗣️

Reaching for -chan and -kun

Calling a 35-year-old colleague 'Yuki-chan' because it sounds affectionate

Anime supplies most visitors' honorific vocabulary, and -chan arrives sounding like a warm little flourish. On an adult you barely know it reads as diminutive — cutesy at best, patronising at worst, and distinctly odd from a stranger. -kun has a different trap: it runs downward through a hierarchy, so a senior person may use it for a junior, but aiming it at someone above you, or at a man you've just met, inverts a relationship in a way people notice.

Leave -chan for children, and use -sama where formality is expected

-chan belongs to small children, family members, pets, and friendships with years behind them. -kun is workplace-internal, used downward or between peers who've settled into it. Neither is something to try out on someone new. In the other direction, -sama (様) is the formal register: it's what businesses call customers (okyaku-sama / お客様), what goes on envelopes, and what you'll hear at hotel desks — you receive it far more often than you use it. 🗣️

Dropping the honorific, or missing a title that outranks it

Barking 'Tanaka!' across the office, or calling your teacher 'Tanaka-san'

Using a bare family name with nothing attached — yobisute (呼び捨て) — is reserved for close friends, family, and clearly established senior-to-junior relationships. From a new acquaintance it sounds curt or superior. The opposite miss is defaulting to -san for someone whose role carries its own honorific: teachers, doctors, lawyers, and politicians are addressed as sensei (先生), and calling your Japanese teacher 'Tanaka-san' in class quietly demotes her.

Use sensei and job titles where they apply — and never on yourself

Sensei stands on its own: Tanaka-sensei, or just sensei, for teachers, doctors, lawyers, politicians, and manga artists. Workplace titles behave the same way — a department head can be Tanaka-buchō (田中部長) or simply buchō, and that outranks -san. As always, the humility rule holds: you never call yourself sensei, and you drop your own colleagues' titles when speaking to outsiders. One small bonus that surprises people — company names take -san too, so a Japanese colleague will refer to a client firm as 'Toyota-san.' 🗣️

Honorifics are a map, not a politeness sprinkle

Every time a name is spoken in Japanese, the suffix on the end says something about the relationship: how close you are, which direction the seniority runs, and — most importantly — whether the person is inside your circle or outside it.

That last distinction, uchi (内) and soto (外), is the one that trips up visitors, because it moves. Your boss is inside your circle at the office and outside it the moment you’re speaking to a client, and his name changes accordingly. Nothing about him changed; the boundary did.

The safe default

Family name + san. Tanaka-san. Use it for everyone until you have a specific reason not to, and you will be correct roughly all of the time.

The refinements worth knowing:

  • -sama (様) — formal. Customers, envelopes, hotel desks. Mostly received, rarely used.
  • -sensei (先生) — teachers, doctors, lawyers, politicians, manga artists. Replaces -san.
  • Job titles — Tanaka-buchō (department head), or just buchō. Also replaces -san.
  • -kun / -chan — internal and downward, or genuinely close. Not for new acquaintances.
  • Nothing at all (呼び捨て) — close friends and family only.

Two habits that make the rest easy

Copy the room. However the people around someone address them is your answer, and it costs nothing to wait a beat and listen before you say a name for the first time.

Use names instead of “you.” English leans on “you” constantly; Japanese avoids it. Anata (あなた) is not the neutral word your textbook implied — pointed at an adult you’ve just met it can feel cold or oddly intimate depending on context. Say “Tanaka-san wa…” where you’d say “do you…” and you’ll sound markedly more natural.

  1. Q1 When you introduce yourself in Japan, should you add -san to your own name?

  2. Q2 Is family name + san a safe default for almost anyone you meet?

  3. Q3 If you're telling a client about your own boss, do you keep the -san on his name?
