Worried in Japanese: 心配しんぱい (shinpai) and the words around it

"Worried" in Japanese is 心配しんぱい (しんぱい, shinpai): say 心配しんぱいです for "I'm worried," 心配しんぱいしている for "I'm worrying about it," and 心配しんぱいしないで for "don't worry."

If you searched "worried in Japanese hiragana," the word is しんぱい, and the kanji are 心こころ (heart) and 配はい (to distribute, to arrange). "Worry in Japanese kanji" gives you the same two characters: 心配しんぱい. The word is easy to learn. The harder part is that Japanese has several neighbours (不安ふあん, 気きになる, 悩なやむ) that English lumps together as "worried," and each one points at something different.

The basics

How do you say "I'm worried" in Japanese?

Use 心配しんぱいです (polite) or 心配しんぱいだ (plain). 心配しんぱい is a noun that behaves like an adjective here, so it takes です or だ directly.

心配しんぱいです。 — I'm worried. (polite, general) ちょっと心配しんぱいだ。 — I'm a little worried. (plain, to yourself or a friend) すごく心配しんぱいしています。 — I'm really worried. (polite, you are in the middle of worrying)

Most learners search "I'm worried in Japanese" and stop at 心配しんぱいです, which is fine. But the natural sentence almost always says what you are worried about, which brings us to particles.

What's the difference between 〜を心配しんぱいする and 〜が心配しんぱいだ?

Both mean "worry about X," but the grammar frames it differently. 心配しんぱいする is a verb (noun + する), so the thing you worry about takes を. 心配しんぱいだ is a state, so the thing takes が.

母ははのことを心配しんぱいしています。 — I'm worried about my mother. (polite, 心配しんぱいする + を) 母ははのことが心配しんぱいです。 — I'm worried about my mother. (polite, 心配しんぱいだ + が) 試験しけんの結果けっかが心配しんぱいだ。 — I'm worried about the exam results. (plain, 心配しんぱいだ + が)

The meaning is nearly identical. The を version sounds like you are actively doing the worrying ("I keep thinking about her"). The が version sounds like the worry is simply a condition you are in ("she's a concern to me"). In speech, people switch between them without thinking, so do not agonise over it.

How does 心配しんぱい change form?

Because 心配しんぱい is a する-verb noun, it conjugates the way every する verb does.

Form Japanese Meaning
Dictionary 心配しんぱいする to worry
Polite 心配しんぱいします worry
Te-form 心配しんぱいして worrying / and worry
Progressive 心配しんぱいしている is worrying
Past 心配しんぱいした worried (finished)
Negative te-form 心配しんぱいしないで don't worry
State 心配しんぱいだ / 心配しんぱいです is a worry / worried

One quiet detail: 心配しんぱいしている describes an ongoing state, so it is the usual way to say "I've been worried (and still am)." 心配しんぱいした on its own usually reports a finished moment, like "I was worried (at that time)."

How do you say "don't worry"?

You have four common options, and the choice depends on who you are talking to.

心配しんぱいしないで。 — Don't worry. (casual, friends and family) 心配しんぱいしないでください。 — Please don't worry. (polite) ご心配しんぱいなく。 — No need to worry. (formal, a set phrase from staff, shops, and business) 心配しんぱいいらないよ。 — There's nothing to worry about. (casual, reassuring)

ご心配しんぱいなく is the one that sounds like a shop assistant waving away an apology. 心配しんぱいしないで is what you say to someone you are close to. 心配しんぱいいらない is the warmest of these, because it states a fact ("no worry is needed") instead of giving an instruction. For the related reassurance 大丈夫だいじょうぶ, see our guide to daijoubu.

Beyond the basics

What is the business phrase ご心配しんぱいをおかけしました?

ご心配しんぱいをおかけしました means "I'm sorry I made you worry." It is the standard apology after you were ill, late, out of contact, or involved in some trouble that people noticed. The literal sense is "I hung worry on you."

ご心配しんぱいをおかけして、申し訳もうしわけありません。 — I'm sorry for making you worry. (formal, business or to a superior) ご心配しんぱいをおかけしました。 — Sorry to have worried you. (polite, after returning from illness or a delay) 心配しんぱいかけてごめんね。 — Sorry for making you worry. (casual, friends and family)

Notice that 心配しんぱいをかける (to cause someone worry) is a full structure of its own. The person who worried is the one being thanked or apologised to. You will hear the same pattern in reverse: 心配しんぱいしてくれてありがとう, "thank you for worrying about me."

How is 不安ふあん different from 心配しんぱい?

心配しんぱい usually has an object: you are worried about something specific. 不安ふあん (ふあん) is closer to unease, a general uncertain feeling that may not have a clear target.

子こどもが熱ねつを出だして、心配しんぱいだ。 — My child has a fever, and I'm worried. (plain, a specific thing) これからどうなるのか不安ふあんだ。 — I'm anxious about how things will turn out. (plain, vague uncertainty about the future) 新あたらしい仕事しごとが不安ふあんです。 — I feel uneasy about the new job. (polite, a general nervousness)

A useful test: if you can finish the sentence "I'm worried that X might happen," 心配しんぱい fits. If it is more "I don't feel settled and I can't point at why," 不安ふあん fits. 不安ふあん is also the feeling of being unsure of yourself, while 心配しんぱい is usually concern for something, often another person. If the feeling is less about the future and more a sense that something is off, see iwakan.

What about 気きになる and 悩なやむ?

These two are the false friends that learners wrongly translate as "worried."

気きになる (きになる) means something bothers you or keeps pulling your attention. It can be negative or just curious.

あの音おとが気きになる。 — That noise bothers me. (plain, mildly negative) 彼かれの返事へんじが気きになる。 — I keep wondering about his answer. (plain, curious and a little anxious)

気きになる is lighter than 心配しんぱい. You can be 気きになる about a new restaurant, but you would not be 心配しんぱい about it. We cover it fully in ki ni naru.

悩なやむ (なやむ) means to be troubled, usually while stuck on a decision or a problem with no clear answer.

進路しんろで悩なやんでいます。 — I'm struggling over my career path. (polite, a decision you can't make) どっちにするか悩なやむ。 — I can't decide which to choose. (plain, torn between options)

The pattern: 心配しんぱい is concern about an outcome, 悩なやむ is being stuck inside a choice, 気きになる is being unable to ignore something, and 不安ふあん is a general feeling of unease. Four words, four different centres.

What is 心配性しんぱいしょう and how do people use it?

心配性しんぱいしょう (しんぱいしょう) means "a worrier," someone who is naturally anxious about everything. It is a personality label, not a complaint.

私わたしは心配性しんぱいしょうなので、早はやめに家いえを出でます。 — I'm a worrier, so I leave home early. (polite, explaining a habit) 心配性しんぱいしょうだなあ。 — You really are a worrier. (casual, teasing)

Said about yourself, it is a gentle explanation. Said about someone else, the tone depends on the smile.

How do people worry out loud in casual speech?

When Japanese speakers are mumbling to themselves, the word 心配しんぱい often does not appear at all. The worry hides inside a soft question.

大丈夫だいじょうぶかな。 — I wonder if it's okay. (casual, self-talk, worry in disguise) 間に合まにあうかな。 — I wonder if I'll make it in time. (casual, self-talk) ちゃんと着ついたかな。 — I wonder if they got there all right. (casual, worrying about someone else)

〜かな is how a worry sounds when it is spoken to yourself. This is a very natural way to say "I'm worried" without ever saying 心配しんぱい. You can also ask someone directly: 大丈夫だいじょうぶ? "Are you okay?" is often the actual question a person is asking when they are worried about you.

How does 心配しんぱい sound in anime?

Anime uses 心配しんぱい for exactly the moments you would expect: the friend who ran off, the character who got hurt, the parent who stays up.

心配しんぱいすんな。 — Don't worry about it. (very casual, masculine, a tough reassurance) 心配しんぱいかけてごめん。 — Sorry for making you worry. (casual, said after a close call) お前まえのことが心配しんぱいなんだよ。 — I'm worried about you, okay? (casual, rough and affectionate, a character who cares but won't say it softly)

心配しんぱいすんな is the contracted spoken form of 心配しんぱいするな, a plain negative command. It is rough on the page and warm in context, because the speaker is saying "I've got this." If someone says it to you in real life, they are probably a close friend, so it sounds friendly. To a stranger or a boss, stay with 心配しんぱいしないでください.

You may also hear the person being worried about respond with the opposite: 大丈夫だいじょうぶ、大丈夫だいじょうぶ. Repeating it twice is the standard way to turn down someone's worry. Another close cousin when you want to show concern in farewells is take care.

Common mistakes

  • Using 心配しんぱい for every kind of nervousness. Nervous before a performance is 緊張きんちょうする, not 心配しんぱい. 心配しんぱい needs something you are concerned about.
  • Using 不安ふあん for worry about another person. 子こどもが不安ふあんです sounds as if the child makes you uneasy. Use 子こどもが心配しんぱいです.
  • Saying 気きになる and meaning "I'm worried." 気きになる is "it bothers me / I'm curious." It will sound lighter than you intend.
  • Using ご心配しんぱいなく to a friend. It is correct but stiff, like saying "No cause for concern" to someone at a party. Use 心配しんぱいしないで.
  • Forgetting the object marker. 母ははを心配しんぱいです is not natural. Pair 心配しんぱいする with を, and 心配しんぱいだ with が.

Practice

Build each answer before opening it. Questions 7 and 8 are a pair: the same worry from two different centres.

1. Say "I'm worried" politely.

Show answer

心配しんぱいです — 心配しんぱい is a noun that takes です directly.

2. Say "I'm worried about my mother" using the verb 心配しんぱいする.

Show answer

母ははのことを心配しんぱいしています — a する-verb takes を for the thing you worry about.

3. Say the same sentence using 心配しんぱいだ.

Show answer

母ははのことが心配しんぱいです — 心配しんぱいだ is a state, so the topic takes が instead of を.

4. What do you say to a friend to mean "don't worry"?

Show answer

心配しんぱいしないで — the casual negative te-form request. ご心配しんぱいなく would be too stiff.

5. A shop assistant waves away your apology. Which set phrase might they use?

Show answer

ご心配しんぱいなく — formal set phrase meaning "no need to worry."

6. You return to work after an illness. What do you tell your manager?

Show answer

ご心配しんぱいをおかけしました — the formal apology for having made people worry.

7. "I'm worried that my child has a fever." Choose between 心配しんぱい and 不安ふあん.

Show answer

心配しんぱい — 子こどもが熱ねつを出だして心配しんぱいだ. There is a specific object, so 心配しんぱい fits.

8. "I feel uneasy about the future, but I can't say why." Choose between 心配しんぱい and 不安ふあん.

Show answer

不安ふあん — これからが不安ふあんだ. The unease is general and has no clear target, so 不安ふあん fits. This is the pair to question 7.

9. You can't decide between two job offers. Which verb fits: 悩なやむ or 気きになる?

Show answer

悩なやむ — 悩なやむ means being stuck in a decision. 気きになる only means something bothers or interests you.

10. What does 間に合まにあうかな mean, and how worried is it?

Show answer

"I wonder if I'll make it in time" — a quiet worry spoken to yourself, using 〜かな instead of the word 心配しんぱい.

During a trial lesson, say 心配しんぱいです about something on your mind, then have your teacher answer with 心配しんぱいしないで.
