What Does “San” Mean?
Understanding Japan’s Most Common Honorific Suffix
If you’ve watched anime, read manga, or had any exposure to Japanese culture, you’ve probably heard people address each other as “Tanaka-san” or “Yamada-san.” But what exactly does “san” mean, and when should you use it?
“San” (さん) is the most common and versatile honorific suffix in Japanese—roughly equivalent to “Mr.,” “Ms.,” “Mrs.,” or “Miss” in English, but much more nuanced. It’s a fundamental part of Japanese social etiquette that shows respect and maintains appropriate social distance.
In this guide, we’ll explore everything you need to know about “san”: its meaning, proper usage, when NOT to use it, and how it fits into the broader system of Japanese honorifics.

What “San” Means
“San” (さん) is an honorific suffix attached to names to show respect and politeness. It has no direct English equivalent because it combines elements of formal titles with social courtesy.
Literal Translation
While “san” doesn’t have a literal translation, its function is similar to:
- Mr./Ms./Mrs./Miss (gender-neutral)
- Sir/Madam (showing respect)
- A polite way of acknowledging someone’s existence and social standing
“San” is more than just politeness—it’s a social lubricant that maintains proper distance (距離感 – kyorikan) between people. Using “san” acknowledges that the other person is a separate individual deserving of respect, not someone overly familiar to you.
Written Forms
How to Write “San”
Note: In everyday writing, “san” is written in hiragana (さん). The kanji 様 (sama) is a more formal, polite version used in business contexts.
When to Use “San”
“San” is incredibly versatile and can be used in most situations. Here’s when you should use it:
1. With Colleagues and Coworkers
2. With Acquaintances and Neighbors
People you know but aren’t close friends with should be addressed with “san”:
3. With People You’ve Just Met
“San” is the default safe choice when meeting someone for the first time:
4. With Service Staff (In Some Contexts)
When service staff introduce themselves by name, you may use “san”:
5. With People Older Than You (But Not Family)
Generally safe for people older than you, though specific honorifics may be more appropriate depending on relationship:
- Older neighbors: ○○さん (san)
- Parents’ friends: ○○さん (san)
- Older classmates: ○○さん (san) or ○○先輩 (senpai)
When NOT to Use “San”
Understanding when NOT to use “san” is just as important:
❌ Never Use “San” For:
- Yourself – Never say “I’m Tanaka-san” (wrong!)
- Your own family members when speaking to others
- Your company/team members when speaking to clients
- Very close friends (use first names or nicknames)
- Young children (use “chan” instead)
- Your superiors in formal settings (use 様 -sama or specific titles)
✓ Exceptions & Special Cases:
- お客様 (okyakusama) – honored customer (not “san”)
- 先生 (sensei) – teachers, doctors (not “san”)
- 社長 (shachou) – company president (use title, not “san”)
- Close friends – Can drop honorifics entirely (呼び捨て)
- Celebrities/Public Figures – Use “san” when discussing them
Wrong: 私は田中さんです。(Watashi wa Tanaka-san desu.)
Correct: 私は田中です。(Watashi wa Tanaka desu.)
Using honorifics for yourself sounds arrogant and awkward—like saying “I am the honorable Mr. Tanaka” in English!

Celebrity/Public Figure Usage
When discussing celebrities or public figures you don’t personally know, “san” is appropriate:
San vs. Other Honorifics
“San” is just one honorific in a complex system. Here’s how it compares to others:
| Honorific | Japanese | Usage | Formality |
|---|---|---|---|
| San | さん | General respectful address – most common | Neutral/Polite |
| Sama | 様 | Very formal – customers, royalty, deities | Very Formal |
| Chan | ちゃん | Children, close friends, cute things | Casual/Cute |
| Kun | くん | Boys, younger males, junior colleagues | Casual/Friendly |
| Sensei | 先生 | Teachers, doctors, lawyers, masters | Respectful |
| Senpai | 先輩 | Seniors, mentors, upperclassmen | Respectful |
| Kouhai | 後輩 | Juniors, younger students (rarely as suffix) | Neutral |
“San” is the safest default choice. It’s polite without being overly formal, and works in nearly all situations. If you’re unsure which honorific to use, “san” is always acceptable.
Important Cultural Rules
1. Hierarchy Matters
Japanese society is structured around vertical relationships (縦社会 – tate shakai). The honorific you use reflects your position relative to the other person:
- Subordinates → Superiors: Use “san” or higher (様, specific titles)
- Peers → Peers: Use “san” (safe choice)
- Superiors → Subordinates: May use “san,” “kun,” or no honorific
2. Inside vs. Outside Group (内 vs. 外)
One of the trickiest concepts for foreigners:
When talking to outsiders about your “inside” group (your company, family), you drop honorifics for your group members, even superiors!
Example:
Wrong: “田中さんは今、会議中です。” (to a client)
Correct: “田中は今、会議中です。” (Tanaka is in a meeting now.)
You’re being humble on behalf of your group by not elevating your colleague when speaking to outsiders.
3. Gender Neutrality
Unlike English (Mr./Ms./Mrs./Miss), “san” is completely gender-neutral:
- 田中さん can be male or female Tanaka
- No need to guess gender or marital status
- Works for non-binary individuals as well
4. First Name vs. Family Name
In Japan, people typically use family names + san except with very close friends:
✓ Appropriate:
- 田中さん (Tanaka-san) – Family name + san
- 山田太郎さん (Yamada Tarou-san) – Full name + san
- 太郎くん (Tarou-kun) – First name + kun (close friends/juniors)
❌ Usually Inappropriate:
- 太郎さん (Tarou-san) with new acquaintances
- Using first names with colleagues (unless very close)
- Mixing Japanese and Western name order
Common Mistakes Foreigners Make
Wrong: 私は田中さんです。
Right: 私は田中です。
This is the #1 mistake learners make! Never use honorifics for yourself—it sounds self-aggrandizing.
Wrong: 私の父さんは医者です。(My father-san is a doctor.)
Right: 私の父は医者です。(My father is a doctor.)
When talking about YOUR family to others, drop honorifics. You’re being humble about your in-group.
With close friends, continuing to use “san” can create unwanted distance. Once friendship is established, it’s okay to drop honorifics or use more casual ones like “chan.”
In Japan, using someone’s first name (even with “san”) implies closeness. Stick with family names until invited to use first names.
Even with colleagues at your level, “san” maintains professional courtesy. Dropping it too early can seem rude or overly familiar.
Key Takeaways:
- ✅ “San” (さん) is a respectful, gender-neutral honorific similar to Mr./Ms.
- ✅ Use “san” with colleagues, acquaintances, and people you’ve just met
- ✅ NEVER use “san” (or any honorific) for yourself
- ✅ Don’t use “san” for your own family when speaking to outsiders
- ✅ “San” is the safest default choice when unsure
- ✅ Attach “san” to family names, not first names (unless very close)
- ✅ Drop honorifics when referring to your company members to clients
- ✅ Be aware of the uchi-soto (inside-outside) distinction
Mastering “San” in Context
“San” is more than just a word—it’s a window into Japanese social structure and values. Understanding when and how to use it properly shows cultural awareness and respect for Japanese social norms.
The good news? “San” is forgiving. As a foreigner learning Japanese, people will be understanding if you make mistakes. The key is to keep learning and paying attention to how native speakers use honorifics in different contexts.
Start by using “san” as your default with new acquaintances, coworkers, and service staff. As you become more comfortable, you’ll naturally learn when to use other honorifics or when to drop them altogether. Language learning is a journey, and mastering honorifics is an important milestone on the path to fluency!
