Japanese honorifics are suffixes and titles such as -san (さん), -kun (くん), -chan (ちゃん), and -sama (さま) that are commonly used in Japan. They express respect, familiarity, affection, or social status, and choosing the right one depends on a few things.

If you’ve ever heard -san, -kun, -chan, or -senpai in anime or everyday Japanese and wondered what they mean, this guide explains the differences, when to use each Japanese honorific, and how to avoid common mistakes.

Most languages use them: “Mr.”, “Mrs”, “Sir”, “Dr”… But in Japanese, there are more of them, and they are a lot more nuanced. They are often attached to a name as a suffix, but some can stand alone, such as sensei.

In Japanese there are both formal and informal honorifics, plus some familial honorifics. The use of honorifics is considered very important in Japan, and calling somebody by just his name without adding a title is a lack of good manners.

Japanese Honorifics: San vs. Kun vs. Chan vs. Sama

The most common Japanese honorifics are -san, -kun, -chan, and -sama, but each one expresses a different level of respect or familiarity. Here’s a quick comparison of when and how they’re used:

In short: -san is the safest and most common Japanese honorific, -kun indicates familiarity or a senior-to-junior relationship, -chan expresses closeness or affection, and -sama shows a much higher level of respect.

What Does -San Mean in Japanese?

-San (さん) is the most common Japanese honorific and is a polite, respectful suffix added after a person’s name. It is often compared to “Mr.,” “Ms.,” or “Mrs.” in English, although -san is gender-neutral and is used much more broadly.

You can use -san when speaking to or about coworkers, acquaintances, people you have just met, and others you want to address politely. If you are unsure which Japanese honorific to use, -san is generally the safest choice in everyday situations.

For example, someone named Tanaka (田中) may be addressed as Tanaka-san (田中さん). The honorific can also be used with certain occupations or roles. For example, honya-san (本屋さん) can refer politely to someone who works at a bookstore.

Is -San Used for Men or Women?

-San can be used for both men and women. Unlike English titles such as “Mr.” and “Mrs.,” the honorific itself does not indicate gender or marital status.

When Should You Use -San?

Use -san when you want to address someone politely without expressing the greater familiarity of -chan or -kun, or the heightened respect of -sama. However, Japanese speakers normally do not attach -san to their own name when referring to themselves.

What Does -Kun Mean in Japanese?

-Kun (くん) is a Japanese honorific commonly used when addressing boys and younger men, as well as people of junior status in schools, workplaces, clubs, and other groups. It usually suggests more familiarity than -san, while still recognizing the relationship between the people involved.

For example, a teacher might address a male student named Haruto (はると) as Haruto-kun (はるとくん). A senior colleague may also use -kun when addressing a junior colleague.

Although -kun is most commonly associated with boys and men, it is not exclusively male. In some school and workplace situations, women may also be addressed with -kun, particularly by someone in a senior position.

When Should You Use -Kun?

-Kun is commonly used for someone of the same or lower social standing when there is an appropriate level of familiarity. Because relationships and hierarchy matter in Japanese, learners should avoid automatically using -kun for every boy or young man they meet. -San is usually the safer choice when you are unsure.

What’s the Difference Between -Kun and -San?

-San is the more neutral and generally polite honorific, while -kun can suggest greater familiarity or a senior-to-junior relationship. When meeting someone for the first time or when you are uncertain which honorific is appropriate, -san is generally the safer option.

What Does -Chan Mean in Japanese?

-Chan (ちゃん) is an affectionate and familiar Japanese honorific commonly added after someone’s name. It can express closeness, fondness, or affection and is often used for children, close friends, family members, loved ones, and sometimes pets.

For example, someone named Yuki (ゆき) might be called Yuki-chan (ゆきちゃん) by a close friend or family member. Using -chan instead of the more neutral -san can make the name sound more familiar or affectionate.

Is -Chan Only Used for Girls?

No. Although -chan is commonly associated with girls and young women, it is not exclusively female. It can also be used for young children regardless of gender and, depending on the relationship and context, for boys or men as an affectionate nickname.

When Should You Use -Chan?

Use -chan when you have a close or affectionate relationship with someone and the honorific is appropriate for that relationship. You may also hear it used for babies, young children, pets, and cute or endearing characters.

Because -chan expresses familiarity, you should not automatically use it with strangers, superiors, or people you have just met. When you’re unsure, -san is generally the safer choice.

What’s the Difference Between -Chan, -San, and -Kun?

-Chan generally expresses more affection or closeness than -san, which is the standard polite honorific. -Kun can also express familiarity, but it is commonly associated with boys, younger men, and senior-to-junior relationships.

What Does -Sama Mean in Japanese?

-Sama (さま) is a highly respectful Japanese honorific used to show greater respect than -san. It is commonly used when addressing customers, clients, guests, or someone who should be treated with a particularly high level of respect.

For example, businesses commonly add -sama to a customer’s name. You may also encounter -sama in formal writing, announcements, and other situations where a high degree of politeness is required.

When Should You Use -Sama?

Use -sama when the situation calls for a higher level of respect than the everyday -san. It is especially common in customer service and formal business contexts.

In normal everyday conversation, however, using -sama instead of -san can sound excessively formal depending on the relationship and situation.

What’s the Difference Between -San and -Sama?

The main difference between -san and -sama is the level of respect. -San is the standard polite honorific used in everyday interactions, while -sama is more respectful and formal.

For example:

Tanaka-san (田中さん) → polite and appropriate in many everyday situations
Tanaka-sama (田中様) → considerably more respectful and formal

If you are unsure which one to use in an ordinary social situation, -san is generally the safer choice.

Other Common Japanese Honorifics

Dono (どの)

Dono (どの) is an old-fashioned honorific that conveys a high level of respect and is rarely used in everyday modern Japanese. You may still encounter it in certain formal contexts, historical settings, fiction, or period dramas.

Niisan / Neesan (兄さん / 姉さん)

Niisan/Neesan (兄さん / 姉さん) is used when referring to one’s older brother or sister, or any relative or close friend.

Jiisan/Baasan (じいさん / ばあさん)

Jiisan/Baasan (じいさん / ばあさん) are used when referring to one’s grandfather and grandmother, and are also used to refer to older adults the speaker is acquainted with. Neither of these are seen as insulting, but watch out not to use them with a person sensitive about his/her age!

Senpai (せんぱい)

Senpai (先輩) refers to someone who is more senior or experienced than you within the same school, workplace, club, or organization. For example, an older student or a colleague who joined a company before you may be considered your senpai.

Unlike -san, -kun, and -chan, senpai can be used both as a title after someone’s name and on its own when addressing someone.

Kōhai (こうはい)

Kōhai (後輩) means a junior or less experienced member of the same group. A younger student, newer club member, or colleague who joined after you may be your kōhai.

Although senpai is commonly used when addressing someone, kōhai is generally used to describe the relationship rather than as a title attached to someone’s name.

What Is the Opposite of Senpai?

The opposite of senpai (先輩) is kōhai (後輩). A senpai is the more senior or experienced person in a school, workplace, club, or other group, while a kōhai is the more junior or less experienced person.

Sensei (せんせい)

Sensei (先生) is a respectful title most commonly used for teachers and instructors. It is also used for certain professionals and experts, such as doctors, lawyers, and accomplished figures in some fields.

Sensei can be used after a person’s name or on its own. For example, a teacher named Tanaka may be addressed as Tanaka-sensei (田中先生) or simply Sensei.

Unlike -san, -kun, and -chan, sensei is more than a general honorific suffix—it refers to a person’s role, expertise, or respected position.

Which Japanese Honorific Should You Use?

Choosing the right Japanese honorific depends on your relationship with the person and the situation. If you’re unsure, -san is generally the safest choice because it is polite and appropriate in many everyday situations.

Here are some common situations:

• Someone you’ve just met: -san
• A coworker or acquaintance: -san
• A boy, young man, or junior you know: -kun may be appropriate
• A child, close friend, loved one, or pet: -chan may be appropriate
• A customer or someone requiring a high level of respect: -sama
• A teacher or instructor: sensei
• A senior member of your school, club, or organization: senpai

Remember that Japanese honorifics reflect relationships and social context, so there isn’t always one honorific that is correct for every person. When in doubt, using -san is usually better than choosing an honorific that sounds too familiar.
