Kanji for Courage: 勇, 勇気, and Which One to Use
The kanji for courage is 勇 (yū — courage, bravery). If you want the word rather than the single character, it is 勇気 (yūki), written 勇 plus 気 (ki — spirit, energy).
The gap between the two is not decorative. 勇 on its own is a raw quality — the bravery inside a person, and one of the most common male given names in Japan. 勇気 is the thing you produce in a moment: the standard Japanese phrase is 勇気を出す (yūki o dasu), literally "put out courage." To a Japanese reader, courage is not something you are. It is something you generate, in a quantity, on demand. That is a different mental picture from the English word, and it explains why 勇気 fits a nine-year-old raising her hand in class just as naturally as it fits a firefighter.
The character up close
The bottom of 勇 is 力 (chikara — strength, power), the same component sitting under 努力 (doryoku — effort) and 勉強 (benkyō — study, where it hides in 勉). That is the part that hints at the meaning: this character is about force being applied. Above it, 田 (a field-shaped box), and above that a small cap stroke.
Here is the thing a native speaker notices instantly and a dictionary will not tell you: the lower two-thirds of 勇 is exactly 男 (otoko — man). 田 over 力. Japanese schoolchildren learn 勇 as "男 wearing a little hat," and adults never quite unlearn it. Historically the top element is phonetic rather than meaningful, so the 男 reading is a mnemonic and not an etymology — but it is the shape the character has in a Japanese mind, and it gives 勇 a faintly masculine, old-fashioned flavor that 勇気 as a full word does not carry.
Readings: yū in compounds, isa in the verb 勇む (isamu — to be in high spirits), and Isamu or Yū as a name. Ten strokes, all of them clean — no cramped areas, no strokes that collapse at small sizes.
Characters people confuse with it
Most bad "courage" choices come from picking a character that means strength, fierceness, or war and assuming courage is included. It usually is not.
| Character | Reading | What it actually carries | When it's the wrong choice |
|---|---|---|---|
| 勇 | yū / isamu | Bravery as an inner quality; also a common man's name | Alone on an object, it often reads as somebody's name |
| 勇気 | yūki | Courage as an act — including small, everyday acts | Never really wrong; slightly plain if you wanted grandeur |
| 勇敢 | yūkan | Valiant, gallant; heroic conduct under real danger | Too heroic for personal struggles or quiet resolve |
| 剛 | gō | Hardness, unyielding toughness; steel that won't bend | Says stubborn strength, says nothing about fear |
| 胆 | tan | Gall bladder; "nerve" or guts, as in 大胆 (daitan — bold) | Alone it is an organ. Boldness ≠ courage |
| 猛 | mō | Fierce, ferocious — used for animals and typhoons | Reads as savagery, not bravery |
| 武 | bu | Martial, military; the 武 of 武道 (budō — martial arts) | The most common mistake: martial ≠ brave |
The honest line between 勇気 and 勇敢: 勇気 is available to everyone, all the time. 勇敢 is a word other people use about you, usually afterward, usually in a news report. You would never say "I acted 勇敢 today." You would absolutely say "I found the 勇気 to call him."
In real life
- 勇気 (yūki — courage). The everyday word. 勇気を出して言った — "I mustered the courage and said it."
- 勇者 (yūsha — brave one, hero). Any Japanese person under fifty reads this as the hero class in a role-playing game. Dragon Quest made 勇者 a household word, and that association is unavoidable — charming or corny depending on your taste.
- 勇敢 (yūkan — brave, valiant). Formal register. Rescue workers, soldiers, the dog that pulled a child from a river.
- 武勇伝 (buyūden — tale of valor). Genuine meaning: a chronicle of martial exploits. Actual modern use: what a coworker calls the story of your embarrassing drunken night, dryly. Worth knowing before you use 武勇 anywhere.
If you're putting it on something
勇 stands alone better than most single characters. It is balanced, the strokes are distinct, and unlike some abstract kanji it does not look like half of a missing word. But be aware of what a Japanese viewer sees first: a single 勇 on a shirt, wall scroll, or forearm reads as a name at least as readily as a virtue. Isamu and Yū are ordinary names. It is roughly like wearing "Grace" in English — the word is right there, and so is the person.
勇気 removes that ambiguity completely. Two characters, no name reading, no possible misreading, and the vertical stack of 勇 over 気 is genuinely well proportioned — both characters are wide and stable, so the column does not go top-heavy the way many two-kanji pairs do. If you want the concept rather than the flavor, choose 勇気.
Avoid 勇敢 for personal display unless you mean it about someone specific, such as a memorial. Claiming valiance about yourself in Japanese lands as bragging in a way "courage" in English does not.
Before you commit to anything permanent, set the characters in a real Japanese typeface and look at them at the actual size — our Japanese font generator will render 勇 and 勇気 vertically and horizontally so you can compare. If you are pairing the kanji with a personal name, remember that names go in katakana, not kanji: our name-to-katakana converter handles that. And if you want a second pair of eyes, send it to us and we'll check a short text for free — we would rather tell you it's fine than have you find out later.

FAQ
Should I get 勇 or 勇気 tattooed?
勇気 if you want the meaning read unmistakably as courage. 勇 if you prefer a single character and don't mind that many Japanese people will half-see a man's name in it. Neither is a mistake; they simply say slightly different things.
Is there a difference between courage and bravery in Japanese?
Yes, and it does not map neatly onto the English pair. Japanese splits by register and scale instead: 勇気 for the ordinary human act, 勇敢 for conduct worthy of public praise, 胆力 (tanryoku — nerve) for the ability to stay calm when things go wrong.
What about 勇気 vs 根性?
根性 (konjō — guts, grit) is endurance, not courage. It is the word a coach shouts on the last lap, and it carries a faintly old-school, sweat-and-suffering tone that some younger Japanese people find dated. If what you actually admire is persistence rather than facing fear, 根性 is the more accurate character choice — but choose it knowing the coach is attached to it.
