Japanese honorifics are the suffixes and title words that show politeness, closeness, rank, affection, or respect. The safest default is さん, while ちゃん, くん, 様, 先輩, and 先生 all signal different relationships and levels of risk.
Fast rule: when in doubt, use さん. It is much easier to sound slightly formal than accidentally disrespectful.
| Honorific | Who it’s used for | Tone | Risk |
|---|---|---|---|
| さん | Most adults, coworkers, classmates, strangers | Neutral and polite | Very low risk; safest default |
| ちゃん | Children, pets, close friends, affectionate nicknames | Cute, intimate | Can sound childish or too close |
| くん | Boys, younger males, some junior coworkers | Junior, casual | Context-dependent outside school/work hierarchies |
| 様 | Customers, high-respect targets, formal writing | Very respectful | Can sound stiff if overused |
| 氏 | News, articles, formal documents | Written-formal | Rare in everyday conversation |
| Title | Japanese | Meaning | When it replaces a suffix |
|---|---|---|---|
| teacher | 先生 | teacher, doctor, instructor | You normally say 田中先生, not 田中さん, for a teacher. |
| senior | 先輩 | older school or workplace senior | Used directly as a title in clubs, teams, and school culture. |
| company president | 社長 | company president | Common as a title inside the company and in some business contexts. |
| department head | 部長 | department manager | Often used as a workplace title instead of adding さん. |
Suffixes like さん, くん, and ちゃん attach to a name. Titles like 先生, 先輩, and 社長 often replace the suffix entirely. Keigo is the wider polite system of respectful and humble speech that changes verbs and sentence style, not just names.
If you are unsure which layer you are dealing with, ask this question: are you changing the name ending, the role word, or the whole sentence register? That distinction solves many beginner mistakes.
A bare name can sound intimate, close, playful, or disrespectful. Which one it becomes depends on the relationship.
When unsure, さん is usually the lowest-risk choice. Honorific choice cannot be reduced to age or gender alone; status, role, closeness, and group culture all matter.
They are suffixes and title words that show politeness, closeness, affection, or rank.
さん is the most common neutral honorific and the safest default in many situations.
ちゃん often sounds cute or affectionate, while くん is common for boys, younger males, or some junior workplace roles.
Yes. 様 shows a higher level of respect and is common for customers and formal writing.
Usually no. Teachers are normally addressed as 先生.
It can be. Without the right relationship, a bare name may sound too direct or disrespectful.
Use さん after a person’s family name when you do not know the relationship well. Use a title such as 先生 when the person’s role is the reason for the address. Avoid choosing ちゃん or くん just because they appear in anime; they need a relationship that supports the familiarity.

Honorific choices depend on relationship, role, age, and setting. This guide describes broadly useful standard-Japanese defaults and marks choices that can sound intimate, hierarchical, or overly formal rather than treating one suffix as universal.
