Useful pattern
In Japanese, name endings attach directly to a person's name: [Name] + さん/くん/ちゃん/様. For example, 佐藤さん (Satō-san), 健くん (Ken-kun), 花子ちゃん (Hanako-chan), お客様 (Okyaku-sama). The choice depends on your relationship with the person and the formality of the situation. さん is the safest default for adults you don't know well. くん is common for boys and men, and sometimes for women in workplace settings, especially among colleagues of similar age or rank. ちゃん is affectionate and often used for young children, close friends, or romantic partners. 様 is highly respectful and appears in customer service, business emails, and formal speech.
When to use it
Use さん with acquaintances, colleagues, and strangers to show basic politeness. Use くん for male friends, subordinates, or boys; it can also be used for female subordinates in some offices, but this varies. Use ちゃん for young girls, close female friends, or anyone you want to address affectionately—but avoid it with strangers or superiors. Use 様 for customers, superiors, or in formal writing. Never use these endings with your own name; they are for addressing others. When in doubt, さん is the safest choice. If someone asks you to use a different ending, follow their preference.
Listen to each line, then take one part and reply out loud.
すみません、田中さんですか？
Excuse me, are you Ms. Tanaka?Sumimasen, Tanaka-san desu ka?はい、田中です。あなたは？
Yes, I'm Tanaka. And you?Hai, Tanaka desu. Anata wa?私は佐藤です。田中さんに会えて嬉しいです。
I'm Satō. Nice to meet you, Ms. Tanaka.Watashi wa Satō desu. Tanaka-san ni aete ureshii desu.こちらこそ、佐藤さん。よろしくお願いします。
Likewise, Mr./Ms. Satō. I look forward to working with you.Kochira koso, Satō-san. Yoroshiku onegai shimasu.A little context goes a long way
In Japanese, the choice of name ending reflects social hierarchy and intimacy. Using the wrong one can sound overly familiar or distant. In business settings, 様 is standard for clients, while さん is used among colleagues. In casual speech, friends may drop the ending entirely or use nicknames. Always pay attention to how others address you and follow their lead.
One thing to watch for
Calling yourself with さん, as in 私は田中さんです (Watashi wa Tanaka-san desu).
Try this instead: When referring to yourself, do not use さん or other endings. Simply say 私は田中です (Watashi wa Tanaka desu). Name endings are for addressing others, not yourself.
Your turn
Try answering out loud before checking a possible answer.

Show a sample answer
鈴木さん (Suzuki-san)
さん is the neutral polite ending for adults in most situations. It is safe and appropriate for a new colleague.
2Your close friend is named Yuki, a young woman. Which ending might you use to show affection?
Show a sample answer
ゆきちゃん (Yuki-chan)
ちゃん is often used for close friends, especially female friends, to express familiarity and affection. Other endings like さん could also be used depending on the relationship, but ちゃん is common here.
3You are writing a business email to a customer named Satō. Which ending should you use?
Show a sample answer
佐藤様 (Satō-sama)
様 is the most respectful ending, appropriate for customers and in formal writing. さん would be too casual in this context.
Use さん as your default for adults, くん for male friends or subordinates, ちゃん for close friends or children, and 様 for formal or customer contexts. Never use these endings with your own name.
