Honorific Titles
Japanese attaches suffixes to names to show respect, closeness, or social position. Using the wrong one — or dropping it when you shouldn't — can change the entire tone of a conversation.
さん is the safe, all-purpose suffix. Use it with anyone you're not particularly close to — coworkers, acquaintances, strangers, neighbors. It works with both family names and given names.
Think of it as the equivalent of 'Mr./Ms.' but much more widely used. When in doubt, use さん.
Examples
- Good morning, Tanaka-san.
田中さん、おはようございます。
- Is Yamada-san's mother doing well?
山田さんのお母さんはお元気ですか。
- Excuse me, is Sato-san here?
すみません、佐藤さんはいらっしゃいますか。
くん is often used for boys and young men, but it's not limited to them. Bosses commonly use くん for subordinates regardless of gender, and it appears in formal settings like the Japanese parliament.
It carries a tone of friendly respect — less formal than さん but not as intimate as ちゃん.
Examples
- Taro-kun, let's play together.
太郎くん、一緒に遊ぼう。
- Tanaka-kun, put together these documents.
田中くん、この資料をまとめてくれ。
- Ken-kun is good at soccer, isn't he?
健くんはサッカーが上手だね。
ちゃん expresses affection and closeness. It's used for small children, close friends, lovers, and pets. Using it with someone you're not close to can sound overly familiar or condescending.
Names are often shortened when paired with ちゃん: 明子 → あっちゃん, ゆうこ → ゆうちゃん. It also replaces さん to sound warmer — おばあちゃん instead of おばあさん (grandma). You'll even hear it for cute things like うさちゃん (bunny).
Examples
- Hana-chan, come here.
花ちゃん、おいで。
- Yuu-chan, are you okay?
ゆうちゃん、大丈夫？
- Acchan, long time no see!
あっちゃん、久しぶり！
さま is the formal, elevated version of さん. You'll encounter it in customer service (お客様), business correspondence (山田様), and on mail/packages.
Using さま in casual conversation sounds sarcastic or excessively formal. It's also used in set phrases like お疲れ様 (otsukaresama) and ご苦労様 (gokurousama).
Examples
- Dear customer, right this way please.
お客様、こちらへどうぞ。
- Yamada-sama, sorry to keep you waiting.
山田様、お待たせいたしました。
- A letter has arrived addressed to Tanaka-sama.
田中様宛にお手紙が届いています。
先生 (せんせい) means 'teacher' but extends to anyone in an expert or guiding role: doctors, lawyers, politicians, martial arts instructors, and authors. It replaces さん entirely — you say 田中先生, not 田中さん先生.
You can also use 先生 on its own without a name to address your teacher or doctor directly.
Examples
- Sensei, I have a question.
先生、質問があります。
- Tanaka-sensei is very kind.
田中先生はとても優しいです。
- Thanks to you, sensei, I was able to pass.
先生のおかげで合格できました。
先輩 (せんぱい) is used for someone senior to you — at school, work, or in a club. 後輩 (こうはい) is the junior counterpart, but it's rarely used as a form of address. You call your senior 先輩 or 田中先輩; they call you by name with くん or さん.
This relationship carries real social weight: senpai are expected to guide and look out for their kouhai.
Examples
- Senpai, please teach me.
先輩、教えてください。
- Tanaka-senpai always helps me.
田中先輩はいつも助けてくれます。
- Looking after the juniors is a senpai's role.
後輩の面倒を見るのは先輩の役目です。
呼び捨て (よびすて) means calling someone by name alone, with no suffix. This signals either very close intimacy (family, best friends, couples) or authority/rudeness.
Dropping the suffix with someone who expects it is considered disrespectful. On the other hand, between close friends, insisting on さん can feel distant. The shift from さん to no suffix often marks a deepening relationship.
Examples
- Taro, come here a sec.
太郎、ちょっと来て。
- Hanako, are you free tomorrow?
花子、明日暇？
- Hey, Tanaka! Hurry up.
おい、田中！早くしろ。
