How to Use Japanese Honorifics: San, Chan, Kun, Sensei, and Senpai

In Japanese, people often add an honorific after someone’s name. These honorifics can show politeness, familiarity, age, occupation, or social position.

In this guide, we explain the differences between -san, -chan, -kun, sensei, and senpai, including when to use them and what to avoid.

Quick comparison table

These are general guidelines. The appropriate honorific can change depending on the relationship, age, workplace, and situation.

1. What Does “-san” Mean?

-san is the most common and generally safe Japanese honorific. It is used for men and women in many everyday and polite situations.

For example:

• Tanaka-san— Mr./Ms. Tanaka

• Yuki-san— Yuki, addressed politely

Unlike English titles such as “Mr.” or “Ms.,” is also commonly used with a person’s first name.

When speaking Japanese, avoid adding to your own name. Japanese speakers normally do not use honorifics for themselves.

2. What Does “-chan” Mean?

-chan is a familiar and affectionate name suffix. It is often used for young children, close friends, family members, pets, and cute characters.

It is commonly associated with girls and women, but it can also be used for boys and men in certain situations, especially when the relationship is close.

For example:

• Mika-chan

• Ken-chan

• Neko-chan— kitty / cat, in an affectionate way

-chan is also commonly used in nicknames. A shortened part of a person’s first name may be combined with -chan to create a friendly nickname. For example, someone named Madoka might be called Ma-chan by family members or close friends.

The exact nickname depends on the person and their relationships. Because -chan sounds familiar and affectionate, it is usually best to use a nickname only when the person introduces themselves that way or invites you to use it. When in doubt, -san is usually safer.

3. What Does “-kun” Mean?

-kun is often used for boys, male students, younger men, or people of lower seniority. It is common in schools, workplaces, clubs, and other group settings.

Although is often associated with males, it can also be used for women in some workplaces or formal group environments.

For example:

• Taro-kun

• Sato-kun

The meaning and tone of depend heavily on the relationship between the speakers. It may sound friendly, professional, or slightly senior depending on the situation.

4. What Does “Sensei” Mean?

For example:

• Yamada-sensei— Teacher/Professor Yamada

• "Sensei, may I ask a question?"

In Japanese, is usually used with a person’s name or by itself. It is not normally combined with another honorific such as -san:

❌ Yamada-san-sensei

Fun Fact: In Japanese, honorifics can sometimes be combined playfully. For example, a YouTuber whose nickname is Yama-chan might jokingly be called Yama-chan-san. Adding -san shows respect, while keeping -chan preserves the creator’s familiar branding name and adds a fun, friendly tone.

5. What Does “Senpai” Mean?

Senpai refers to someone who joined a school, club, workplace, or organization before you. This person usually has more experience in that group.

A is not necessarily older than you. For example, a younger student can be your if they entered the school before you.

For example:

• Tanaka-senpai

• "Senpai, could you show me how to do this?"

Senpai describes a relationship within a group. It does not simply mean “an older person.”

6. What Is the Difference Between -san, Sensei, and Senpai?

-san is a general polite honorific. recognizes someone as a teacher or respected professional, while describes someone who has more experience or seniority within a particular group.

7. Why Do Japanese People Sometimes Use Only a First Name?

Japanese speakers sometimes use a person’s name without an honorific when they are close to that person. This is called using the name without a suffix, or yobisute*.

However, using someone’s name without an honorific can sound too direct if you are not close to them.

*Yobisute (呼び捨て) means calling someone by their name without adding an honorific.

8. Common Mistakes to Avoid

Mistake 1: Everyone is called “-chan”

-chan is not a universal friendly version of -san. It can sound too familiar when used with someone you do not know well.

Mistake 2: Using honorifics for yourself

Japanese speakers generally do not use -san, -chan, or -kun when referring to themselves.

Mistake 3: Adding two honorifics together

Do not normally combine honorifics, such as Yamada-san-sensei or Tanaka-san-senpai.

Mistake 4: Assuming “senpai” means older

Senpai refers mainly to experience or length of membership in a group, not simply age.

Mistake 5: Calling a teacher by their first name

In a formal school setting, calling a teacher by their first name without an appropriate title may sound overly casual.
