Hero in Japanese: ヒーロー, 英雄えいゆう, 勇者ゆうしゃ, 主人公しゅじんこう — and the villain 悪役あくやく

"Hero" in Japanese depends on the kind of hero: ヒーロー (hiiroo) for superheroes and everyday heroes, 英雄えいゆう (えいゆう) for great heroes of history and legend, 勇者ゆうしゃ (ゆうしゃ) for the brave hero of a fantasy RPG, and 主人公しゅじんこう (しゅじんこう) for the main character of any story.

English uses "hero" for all of these, and anime subtitles do too. But a Japanese fan instantly hears the difference between the ヒーロー of 僕ぼくのヒーローアカデミア, the 勇者ゆうしゃ who defeats the Demon King, and the 英雄えいゆう whose statue stands in a town square. This post sorts the hero words, adds the villain words, and shows a few phrases you can use about real people.

How do you say "hero" in Japanese?

What is ヒーロー?

ヒーロー is the loanword "hero", used for superheroes and for everyday heroes.

子こどもの頃ころ、ヒーローになりたかった。 — When I was a kid, I wanted to be a hero. (casual) 彼かれはチームのヒーローだ。 — He's the team's hero. (casual, sports)

ヒーロー is warm and modern. Sports news calls the player who wins the game the ヒーロー, and an interview with that player is a ヒーローインタビュー, a standard part of Japanese baseball broadcasts. The superhero series 僕ぼくのヒーローアカデミア, My Hero Academia, uses this word.

What is 英雄えいゆう?

英雄えいゆう (えいゆう) is a great hero of history or legend: someone admired for extraordinary deeds.

彼かれは国くにの英雄えいゆうだ。 — He's a national hero. (neutral, serious) 英雄えいゆうの物語ものがたり — the tale of a hero (neutral, epic stories)

英雄えいゆう sounds grand and serious. You would use it for historical figures, war heroes or legendary warriors, not for a friend who helped you move house.

What is 勇者ゆうしゃ?

勇者ゆうしゃ (ゆうしゃ), "brave one", is the hero of fantasy games and stories, especially the chosen one who defeats the Demon King.

勇者ゆうしゃは魔王まおうを倒たおした。 — The hero defeated the Demon King. (neutral, the classic RPG plot)

The pair 勇者ゆうしゃ and 魔王まおう comes from Japanese RPGs and has spread into countless isekai stories. 勇いさみ means "courage", as in 勇気ゆうき (ゆうき). Our post on courage in Japanese covers that word.

Beyond the basics

What is 主人公しゅじんこう?

主人公しゅじんこう (しゅじんこう) is the protagonist, the main character, whether or not they are heroic.

この漫画まんがの主人公しゅじんこうは普通ふつうの高校生こうこうせいだ。 — The protagonist of this manga is an ordinary high school student. (neutral)

A 主人公しゅじんこう can be a villain, a slacker or a cat. When English speakers say "the hero of the story" meaning the main character, Japanese says 主人公しゅじんこう. The female lead is often called ヒロイン.

What is 正義せいぎの味方みかた?

正義せいぎの味方みかた (せいぎのみかた), "an ally of justice", is the classic phrase for a hero who fights for what is right.

正義せいぎの味方みかたが来きたぞ! — The champion of justice is here! (casual, a cheerful superhero line)

It sounds a little old-fashioned and playful today, like a children's TV hero. People also use it jokingly: 正義せいぎの味方みかた気取きどり, "acting like a champion of justice". Our post on 味方みかた explains the word for "ally".

How do you say "villain"?

悪役あくやく (あくやく) is the villain role in a story; 敵てき (てき) is an enemy; ヴィラン is the superhero-style loanword.

このアニメの悪役あくやくは魅力的みりょくてきだ。 — The villain in this anime is fascinating. (neutral) 敵かなを倒たおせ! — Defeat the enemy! (rough, a battle cry)

悪役あくやく literally means "bad role", and it is also used for actors who play villains. ダークヒーロー is a hero with dark methods, and many fans prefer them.

How do you call a real person your hero?

Say あなたは私わたしのヒーローです for a light compliment, or 命いのちの恩人おんじん (いのちのおんじん) for someone who truly saved you.

助たすけてくれて、ありがとう。あなたは私わたしのヒーローです。 — Thank you for helping me. You're my hero. (polite, warm) あの医者いしゃは私わたしの命いのちの恩人おんじんです。 — That doctor saved my life. (polite, serious)

憧あこがれ (あこがれ), "someone you look up to", is another natural choice: 彼かれは私わたしの憧あこがれです, "He's my role model".

What is a ヒーローインタビュー?

It is the on-field interview with the star player after a game, a fixture of Japanese baseball and other sports.

今日きょうのヒーローインタビューは誰だれ? — Who's getting the hero interview today? (casual)

The player usually thanks the fans with lines like 応援おうえんありがとうございました, and the crowd cheers. It is a great example of ヒーロー in everyday Japanese.

What do heroes say in anime?

A few short lines appear again and again, and they are good examples of confident, casual Japanese.

任まかせろ! — Leave it to me! (rough, confident, 任まかせる = to entrust) 私わたしが来きた! — I am here! (the famous entrance line of All Might in 僕ぼくのヒーローアカデミア) みんなは俺おれが守まもる。 — I'll protect everyone. (rough male speech, a classic vow)

任まかせろ is the rough command form of 任まかせる. In polite speech, the same idea is 任まかせてください, "please leave it to me", which you can use at work when you volunteer for a task. The anime version is fun to recognize; the polite version is the one to actually use.

Common mistakes

  • Calling a friend 英雄えいゆう for a small favor. It sounds absurdly grand. Use ヒーロー or just thank them.
  • Calling every main character a hero. If you mean the protagonist, say 主人公しゅじんこう.
  • Using 勇者ゆうしゃ for a real person. It sounds like a game character, unless you are joking.
  • Mixing up 悪役あくやく and 悪者わるもの. 悪役あくやく is the villain role in a story; 悪者わるもの (わるもの) is a bad guy in general.
  • Reading 主人公しゅじんこう as しゅじんおおやけ. It is しゅじんこう.

I'm Yuuki, a Japanese teacher based in Tokyo. I've taught on italki as a Top 1% teacher and watched over 1,500 anime, so most of the example sentences on this blog come from lines I've actually heard students ask about. Hero words are a good example of how one English word splits into several Japanese ones, each with its own world.
