気が強い
When someone is described as 気が強い (ki ga tsuyoi), it means they have a strong will and are assertive. They aren't easily swayed by others and tend to stand their ground.
This adjective often describes someone who is determined and can be seen as tough or resolute. It's a useful phrase to know when talking about personality traits in Japanese.
When we describe someone with 気が強い (ki ga tsuyoi), we're saying they have a strong spirit or will. This person is not easily swayed by others and often stands firm in their beliefs and decisions. They might be assertive in expressing their opinions or very determined when pursuing a goal.
It's important to note that while it can mean someone is tough or strong-willed, it doesn't necessarily carry a negative connotation of being stubborn or difficult, although it can be used that way depending on the context.
When you're learning Japanese, you'll encounter many expressions that don't translate word-for-word. 気が強い (ki ga tsuyoi) is a great example. It literally means 'spirit is strong,' but it's used to describe someone who is strong-willed, assertive, or even tough. This isn't usually about physical strength, but rather a mental or personality trait.
Imagine someone who doesn't back down easily, stands up for themselves, or has a firm opinion. That's a good candidate for 気が強い. It can be used in both positive and sometimes slightly negative ways, depending on the context and tone.
§ What does 気が強い mean?
- Definition
- Strong-willed, assertive, tough. It describes a personality trait where someone is not easily swayed, stands their ground, or has a firm spirit.
The 'ki' (気) in 気が強い is a very important concept in Japanese. It can mean spirit, mind, mood, or energy. When this 'ki' is 'tsuyoi' (強い), or strong, it means their inner disposition is robust. Think of it as having a strong inner core.
§ When do people use 気が強い?
You'll hear 気が強い used in many situations to describe people. Here are a few common scenarios:
- Describing someone who is a leader: A person who takes charge and isn't afraid to make decisions might be described as 気が強い.
- Talking about someone who is resilient: If someone faces challenges and doesn't give up, they are 気が強い.
- Discussing a person who speaks their mind: Someone who expresses their opinions clearly and confidently, even if others disagree, is often called 気が強い.
- In sports or competition: Athletes who are competitive and mentally tough are said to be 気が強い.
It's often used when talking about women, but it's not exclusive. Sometimes, when applied to women, it can carry a slight nuance of 'being bossy' or 'too assertive' in a traditional sense, but this depends heavily on context and the speaker's perspective. Generally, it's a neutral-to-positive trait emphasizing determination.
§ Examples in context
彼女は気が強いから、どんな困難も乗り越えられるだろう。(She is strong-willed, so she will probably overcome any difficulty.)
彼は見た目によらず気が強い性格だ。(He has a strong-willed personality, contrary to his appearance.)
もう少し気が強くならないと、この仕事は務まらないよ。(If you don't become a bit more assertive, you won't be able to handle this job.)
§ Don't Confuse 気が強い with Being Mean
Many learners mistakenly think that someone who is 気が強い (ki ga tsuyoi) is automatically aggressive or unpleasant. This isn't always true. While a strong-willed person can sometimes be perceived negatively, 気が強い itself simply describes someone with a firm personality, someone who stands their ground, or is assertive. It doesn't inherently carry a negative connotation of being unkind or harsh.
§ Using 気が強い for Physical Strength
This is a common error. 気が強い refers to mental or emotional strength, not physical strength. If you want to talk about someone being physically strong, you would use words like 強い (tsuyoi) or 力持ち (chikaramochi).
- Wrong Usage Example
- 彼女は気が強いから、重い荷物を一人で運べる。(Kanojo wa ki ga tsuyoi kara, omoi nimotsu o hitori de hakoberu.) - *Incorrectly implies her strong will helps her carry heavy things.*
- Correct Alternative
- 彼女は力が強いから、重い荷物を一人で運べる。(Kanojo wa chikara ga tsuyoi kara, omoi nimotsu o hitori de hakoberu.) - *She is physically strong, so she can carry heavy luggage by herself.*
Remember, 気が強い describes someone's character or personality, not their muscles.
§ Overusing It in Every Assertive Situation
While 気が強い is good for describing assertiveness, it's not the only word. Sometimes, other expressions fit better depending on the nuance you want to convey. For example, if someone is simply confident, you might use 自信がある (jishin ga aru). If they are very determined, you could say 決断力がある (ketsudanryoku ga aru).
- 自信がある (jishin ga aru): Confident.
- 積極的 (sekkyokuteki): Proactive, positive.
- 粘り強い (nebarizuyoi): Persistent, tenacious.
- 決断力がある (ketsudanryoku ga aru): Decisive.
Using 気が強い indiscriminately for any 'strong' characteristic can make your Japanese sound less natural. Consider the specific type of strength or assertiveness you want to highlight.
彼女は気が強いので、自分の意見をはっきり言います。(Kanojo wa ki ga tsuyoi node, jibun no iken o hakkiri iimasu.)
(She is strong-willed, so she clearly states her opinions.)
彼は気が強いけれど、優しい一面もあります。(Kare wa ki ga tsuyoi keredo, yasashii ichimen mo arimasu.)
(He is assertive, but he also has a kind side.)
Pay attention to context and the specific nuance you want to convey. While 気が強い is a versatile adjective, like any word, it has its best applications.
§ Similar words and when to use this one vs alternatives
When you're describing someone as strong-willed or assertive in Japanese, you have a few options. Let's look at some similar words and when to choose 気が強い (ki ga tsuyoi) over the others.
- Definition
- Strong-willed, assertive, tough.
気が強い generally describes someone who is determined, doesn't easily give up, and might be a bit stubborn. It can have a slightly negative nuance, suggesting someone is perhaps too assertive or bossy, but it's often used neutrally or even positively to praise someone's resilience.
彼女は気が強いので、どんな困難にも負けません。
She is strong-willed, so she won't be defeated by any difficulty.
Let's compare it with some other common words:
頑固 (がんこ - ganko): This also means stubborn, but it often carries a more negative connotation than 気が強い. While someone who is 気が強い might be stubborn in pursuing their goals, a 頑固 person is often stubbornly unwilling to change their mind or compromise, even when it's unreasonable.
彼は頑固なので、なかなか意見を変えません。
He is stubborn, so he rarely changes his opinion.積極的 (せっきょくてき - sekkyokuteki): This means proactive, positive, or assertive in a generally positive way. It describes someone who takes initiative and is enthusiastic. While a 気が強い person might be proactive, 積極的 focuses more on their actions and attitude rather than their inner strength or will.
彼女はいつも積極的にイベントに参加します。
She always actively participates in events.負けず嫌い (まけずぎらい - makezugirai): This word literally means "hates losing," and it perfectly describes someone who is competitive and determined to win. A person who is 気が強い is often 負けず嫌い, but the latter specifically highlights their competitive spirit.
彼は負けず嫌いなので、スポーツではいつも全力を尽くします。
He hates to lose, so he always gives his best in sports.
So, when should you use 気が強い? Use it when you want to emphasize someone's inner strength, their mental toughness, and their determination to stand firm or overcome challenges. It's a good all-rounder for 'strong-willed' or 'assertive' without necessarily implying a negative or overly competitive trait, though it can lean that way depending on context.

Frequently Asked Questions
10 questionsYou can use 気が強い like any other い-adjective. For example, 彼女は気が強い (Kanojo wa ki ga tsuyoi) means 'She is strong-willed.' You can also say 気が強い人 (ki ga tsuyoi hito) which means 'a strong-willed person.'
It can be both, depending on the context. Being strong-willed can be a positive trait, showing determination. However, if someone is too 気が強い, it might imply stubbornness or being bossy, which can be negative.
強い (tsuyoi) is a general word for 'strong' – it can refer to physical strength, strength of an object, or even a strong feeling. 気が強い specifically refers to a person's inner strength, their will, or personality. So, a strong person might be 強い, but a strong-willed person is 気が強い.
Yes, 気が強い can be used for both men and women. There's no gender restriction on this phrase.

It's generally not considered rude, but like any descriptor, context matters. If you say it admiringly, it's positive. If you say it with a critical tone, it could be perceived negatively, implying stubbornness or difficulty.
While technically possible, it's more commonly used for people. If you wanted to describe a determined animal, you might use other words like 勇敢な (yuukan na - brave) or 活発な (kappatsu na - active/lively).
Here, 気 (ki) refers to one's spirit, mind, or disposition. So, 気が強い literally translates to something like 'spirit is strong' or 'mind is strong,' conveying the idea of being strong-willed.
