人見知ひとみしり (hitomishiri): shy around strangers — and 内気うちき, shy by nature

人見知ひとみしり (hitomishiri) describes feeling shy, nervous, or withdrawn specifically around people you don't know yet — it usually fades once you get used to someone. 内気うちき (uchiki) describes a general shy, quiet personality that doesn't depend on how familiar you are with the people around you.

English flattens both of these into "shy," but Japanese keeps them apart, and the difference matters for describing yourself and other people accurately. Someone can be 人見知ひとみしり without being 内気うちき at all — chatty and relaxed with close friends, but nervous for the first ten minutes with anyone new. Someone else can be the opposite: quiet even among old friends, but not particularly anxious meeting new people. Mixing the two up is one of the most common small mistakes learners make when describing personality.

The basics

人見知ひとみしりする: shy specifically toward new people

人見知ひとみしり is most often used with する, as 人見知ひとみしりする — literally "to do stranger-shyness." It originally described babies who cry at unfamiliar faces, and that meaning is still alive, but adults use it constantly about themselves too.

子供こどもが人見知ひとみしりして泣ないた。 — The child got shy around the stranger and cried. (casual, the classic use with babies and toddlers) 私わたしは人見知ひとみしりするタイプです。 — I'm the type who gets shy around people I don't know. (polite, a very common self-introduction line)

人見知ひとみしり can also stand alone as a noun describing the trait itself, as in 人見知ひとみしりだ or 人見知ひとみしりです, without する — both forms are natural, and 人見知ひとみしりする slightly emphasizes the reaction happening in the moment. As a noun it also names a baby stage, as in 最近さいきん、人見知ひとみしりが始はじまった, and baby in Japanese sets it beside 夜泣よなき and ハイハイ, the words parents use for what babies do.

内気うちきな性格せいかく: quiet by nature, not just around strangers

内気うちき is a な-adjective describing someone whose default personality is quiet, reserved, and unassertive — regardless of whether the people around them are strangers or lifelong friends.

彼かれは内気うちきな性格せいかくです。 — He has a shy, quiet personality. (neutral, descriptive) 内気うちきなので、自分じぶんから話はなしかけるのが苦手にがてです。 — Because I'm reserved, I'm not good at starting conversations myself. (polite, common self-description)

Where 人見知ひとみしり is about a reaction that eases with familiarity, 内気うちき describes a trait that stays roughly constant no matter who's in the room. That's the core split: 人見知ひとみしり is situational, 内気うちき is dispositional.

Beyond the basics

人見知ひとみしり vs 内気うちき: they can overlap, but they don't have to

Because both words get translated as "shy," learners often assume they always go together. In practice, plenty of people are one without the other.

人見知ひとみしりだけど、仲良なかよくなったらすごくよく喋しゃべります。 — I'm shy with new people, but once we get close I talk a lot. (polite, describes 人見知ひとみしり without 内気うちき) 内気うちきだから、友達ともだちの前まえでもあまり話はなしません。 — I'm reserved, so I don't talk much even in front of friends. (polite, describes 内気うちき without necessarily being 人見知ひとみしり)

If you want to describe someone who is shy in general, both around strangers and among friends, you can use both words together: 人見知ひとみしりで内気うちきな人ひと ("a person who's shy with strangers and reserved in general") — it's not redundant, because it covers both the situational and the constant sides at once.

恥はずかしがり屋や: the noun for "a shy person," with a blushing flavor

恥はずかしがり屋や (hazukashigariya, literally "a person who does 恥はずかしい") is close to 内気うちき in meaning but leans toward embarrassment and self-consciousness — think blushing, avoiding attention, and disliking being looked at — rather than quiet reserve in conversation.

妹いもうとは恥はずかしがり屋やで、写真しゃしんを撮とられるのが苦手にがてです。 — My little sister is shy/bashful, and she's not good at having her picture taken. (polite, family description)

内気うちき is closer to "introverted, quiet, reserved," while 恥はずかしがり屋や is closer to "bashful, easily embarrassed, camera-shy." They overlap heavily in practice, but 恥はずかしがり屋や fits moments of visible embarrassment better than 内気うちき does, similar to the personality adjectives that shift meaning depending on exactly which flavor of a trait you're pointing at.

人見知ひとみしりを克服こくふくする: growing out of it

克服こくふくする (kokufuku suru, "to overcome") pairs naturally with 人見知ひとみしり, because it is widely treated as something you can work on, more than a lasting personality trait (though 内気うちきを克服こくふくする is also said).

人見知ひとみしりを克服こくふくしたいです。 — I want to overcome my shyness around new people. (polite, a very common stated goal)

This is one more piece of evidence for the situational/dispositional split: people talk about "overcoming" 人見知ひとみしり the way they'd talk about improving a habit, but 内気うちき is discussed more like a fixed part of who someone is.

Common mistakes

  • Using 人見知ひとみしり for a lasting personality trait that has nothing to do with strangers. If someone is quiet even with close friends, 内気うちき is the accurate word, not 人見知ひとみしり.
  • Treating 内気うちき as a する-verb. 内気うちきする doesn't exist — 内気うちき only works as a な-adjective (内気うちきな, 内気うちきです), unlike 人見知ひとみしりする.
  • Confusing 恥はずかしい with 恥はずかしがり屋や. 恥はずかしい describes a single moment's feeling of embarrassment; 恥はずかしがり屋や describes a type of person who tends to feel that way often.
  • Assuming 人見知ひとみしり only applies to children. It's used constantly by and about adults — in job interviews, dating conversations, and everyday small talk about personality.

人見知ひとみしり vs 内気うちき vs 恥はずかしがり屋や

Word Reading What it describes Fades with familiarity?
人見知ひとみしり ひとみしり Shyness specifically around unfamiliar people Yes — that's the defining feature
内気うちき うちき A generally quiet, reserved personality No — stays fairly constant
恥はずかしがり屋や はずかしがりや A person prone to embarrassment, bashfulness Partly — situational triggers, habitual pattern

FAQ

Is 人見知ひとみしり a negative trait to admit to? Not at all — it's an extremely common, neutral self-description in Japanese, often said with a small laugh rather than as a complaint.

Can adults use 人見知ひとみしり, or is it only for babies? Adults use it constantly, especially in self-introductions and when explaining why they seemed quiet at first. The baby-crying-at-strangers meaning is just the original, most literal use.

What's the opposite of 内気うちき? 社交的しゃこうてき (shakouteki, "sociable, outgoing") is the most common opposite — describing someone comfortable talking to anyone, familiar or not.

Is 恥はずかしがり屋や only used for children? No, though it does show up a lot in family contexts. Adults use it too, especially about themselves in situations like being photographed, praised in public, or asked to speak up.

How do I say "I'm not shy at all"? 人見知ひとみしりしません or 全然ぜんぜん人見知ひとみしりしません ("I don't get shy around strangers at all") works for the situational meaning; 内気うちきじゃありません covers the personality-trait meaning.
