What Does さん (San) Mean in Japanese Names?

It's your first day in a Japanese class. You meet someone named Tanaka, and you want to greet them politely. Should you just say their name, or add something after it?

The short answer

さん (san) is a respectful ending added to someone's name. It's a common way to address or refer to another person politely, and it works regardless of gender.

Here, たなか (Tanaka) is the person's name, and さん (san) adds politeness.

You can think of it as a friendly, respectful way to use someone's name without sounding overly familiar.

Put さん directly after someone's name

In Japanese, さん (san) is an honorific, meaning a word ending or title that helps express respect or social relationships.

It attaches directly to a name.

For example, imagine someone introduces you to a person named Tanaka.

Notice that さん (san) comes immediately after たなか (Tanaka).

There's no separate word between them.

You can use さん (san) with family names or given names, depending on the relationship and situation.

For beginners, using someone's family name with さん (san) is often a sensible starting point in polite everyday interactions.

Use さん when greeting or thanking someone

Imagine you're arriving at class.

Your classmate Yamada is already there.

You can greet them by name.

Here, おはようございます (ohayou gozaimasu) is a polite way to say "good morning."

Adding さん (san) to Yamada's name helps keep the greeting respectful.

Now imagine another classmate, Sato, helps you find your notebook.

You want to thank them.

The phrase ありがとうございます (arigatou gozaimasu) means "thank you."

Notice that さん (san) doesn't change the meaning of the greeting or thanks.

It changes how you're addressing the person.

Leave さん off your own name

Here's a mistake English-speaking beginners sometimes make.

You learn that さん (san) is polite, so you assume you should add it whenever you say a name.

But you normally don't add さん to your own name when introducing yourself.

Imagine your name is Tanaka.

You can say:

The word わたし (watashi) means "I."

Notice that your name doesn't have さん (san) attached.

That's because さん (san) expresses respect toward the person being named. Adding it to your own name in an ordinary self-introduction can sound like you're giving yourself an honorific.

Now compare two situations.

When introducing yourself:

When someone else introduces Tanaka:

The name is the same.

What changes is who is being introduced.

If you're learning introductions, the はじめまして lesson explains how to begin a first conversation politely.

Don't translate さん as Mr. or Ms. every time

You might see さん (san) translated as "Mr.," "Mrs.," or "Ms."

That can be useful, but it's not an exact match.

Unlike those English titles, さん (san) doesn't tell you someone's gender or marital status.

It can also appear in situations where English wouldn't normally use a title.

For example, imagine you're talking about your classmate Sato.

Here, がくせい (gakusei) means "student."

The particle は (wa) introduces the person you're talking about.

In natural English, we might simply say "Sato is a student."

We don't need to translate さん (san) separately.

That's because its function is to express respect, not to provide information about the person's gender.

Use the right title for a teacher

Now imagine you're greeting your Japanese teacher.

Their name is Tanaka.

Instead of さん (san), you can use せんせい (sensei), meaning "teacher."

Here, せんせい (sensei) follows the teacher's name.

It identifies their role rather than simply adding the general respect expressed by さん (san).

You'll also encounter せんせい (sensei) when addressing people in certain other professions, including doctors.

The important beginner lesson is that さん (san) isn't the only respectful name ending in Japanese.

Different relationships and situations can call for different forms of address.

Common mistakes

• Adding さん to your own name. When introducing yourself, say たなかです (Tanaka desu), not たなかさんです (Tanaka-san desu). You normally don't give yourself an honorific.
• Assuming さん means someone is male or female. さん (san) works regardless of gender. Don't treat it as a direct equivalent of only "Mr." or only "Ms."
• Thinking さん is required after every name. Japanese has different forms of address depending on relationships and situations. Close friends might use names without さん, while teachers may be addressed using せんせい (sensei).
• Assuming さん always sounds formal or distant. It can be used in ordinary, friendly conversations too. Its meaning depends partly on the relationship between the speakers.

Practise using さん

Imagine you're meeting three people at a Japanese class.

Their names are Tanaka, Yamada, and Sato.

First, greet Tanaka.

Now replace たなか (Tanaka) with やまだ (Yamada).

Say the new greeting aloud.

Next, imagine Sato helps you with your homework.

Thank them using their name.

Finally, imagine you're introducing yourself.

Your name is Tanaka.

Say the sentence aloud.

Did you remember to leave さん (san) off your own name?

Now imagine greeting your teacher, Tanaka.

Practise switching between さん (san), せんせい (sensei), and no honorific depending on whom you're addressing.

Keep this in mind

さん (san) is a respectful ending added to another person's name, but it isn't exactly the same as English "Mr." or "Ms." You normally leave it off your own name, and some relationships or roles call for different forms of address. When meeting someone in a polite everyday setting, name + さん is a useful starting point.
