niau-vs-muiteiru

2021年6月25日2026年4月21日

Your friend tells you they want to become a nurse. You want to say “That really suits you!” — but do you say 似合う or 向いている? Both can translate as “suits you,” but using the wrong one can cause genuine confusion. 似合う is about looks; 向いている is about personality and aptitude. This guide makes the distinction permanent.

Yuka

Quick question, Rei — when should I use 似合う versus 向いている?

Rei

Ah, a classic mix-up! They’re related but definitely not interchangeable. I’ll explain with examples and it’ll make perfect sense.

似合う — Looks Good On You

似合う describes a visual match between a person and something they wear or how they present themselves. It is the word you use for complimenting someone’s clothes, hairstyle, color choice, or accessories. The focus is entirely visual — does this item create a good look on this specific person?

似合う follows the pattern: [item/style] + が + [person] + に + 似合う. The item is the subject, and the person is marked with に.

Example 1 — clothing:

その帽子、よく似合ってるよ。
Sono boushi, yoku niatteru yo.
That hat looks really good on you.

Example 2 — hairstyle:

短い髪型があなたに似合いますね。
Mijikai kamigata ga anata ni niaimasu ne.
Short hair suits you.

Example 3 — formal compliment:

お似合いですよ。
Oniai desu yo.
It looks great on you. (formal / sales-floor style)

Yuka

Oh interesting! So 似合う can mean that too? I only knew the basic meaning.

Rei

Yes! 似合う is more versatile than most learners realize. Native speakers use it in all sorts of situations — not just the obvious ones.

向いている — Cut Out For It (Aptitude and Fit)

向いている means someone has the aptitude, temperament, or natural ability for something — usually a job, activity, or role. It comes from the verb 向く (muku) meaning “to face / to be pointed toward,” used here in the resultant-state form 向いている.

向いている is the word for “cut out for it,” “well-suited for it,” or “has a knack for it.” It says nothing about appearance — it is all about inner qualities and capability.

Example 1 — job:

あなたは教師に向いていると思う。
Anata wa kyoushi ni muiteiru to omou.
I think you are cut out to be a teacher.

Example 2 — activity:

彼女はチームワークに向いている。
Kanojo wa chiimuwaaku ni muiteiru.
She is well-suited for teamwork.

Example 3 — negative (not cut out for it):

私は営業に向いていないと思う。
Watashi wa eigyou ni muiteinai to omou.
I don’t think I’m cut out for sales.

Yuka

What about 向いている? Is it used as often as 似合う in daily conversation?

Rei

向いている is super common too! The two words actually complement each other really well once you understand both.

The Core Difference: Looks vs. Aptitude

The simplest way to remember: 似合う = “Does it look good on you?” 向いている = “Are you the right type of person for this?” Here is a sentence that uses both:

その制服は彼女に似合っているけど、仕事自体は彼女に向いていないかもしれない。
Sono seifuku wa kanojo ni niatteiru kedo, shigoto jitai wa kanojo ni muiteinai kamoshirenai.
The uniform looks good on her, but the job itself might not be suited to her.
