Stubborn in Japanese: 頑固がんこ (がんこ), 意地いじっ張はり, and the stubborn that is a compliment

"Stubborn" in Japanese is 頑固がんこ (がんこ): 頑固がんこな人ひと means "a stubborn person". For someone who refuses to back down out of pride, use 意地いじっ張はり (いじっぱり), and for stubbornness you admire, say 粘り強ねばりづよい (ねばりづよい), "persistent".

English uses one word, "stubborn", for three quite different people: the one who will not change their mind, the one who will not admit they were wrong, and the one who will not give up. Japanese splits them. That split is the most useful thing to learn here, because picking the wrong one can turn a compliment into a complaint. This post covers 頑固がんこ first, then the words around it, then how anime uses them.

What does 頑固がんこ mean, and how do you use it?

Is 頑固がんこ an adjective?

Yes, 頑固がんこ is a な-adjective: 頑固がんこな before a noun, and 頑固がんこだ or 頑固がんこです at the end of a sentence. It describes someone who sticks to their own way and will not listen to other opinions.

父ちちはとても頑固がんこです。 — My father is very stubborn. (polite, describing a family member) 頑固がんこな人ひとと話はなすのは疲つかれる。 — Talking with stubborn people is tiring. (casual, a general complaint)

The kanji give the picture. 頑がん means hard-headed or obstinate, and 固こ means hard or solid, the same 固こ as in 固かたい (hard). A 頑固がんこな人ひと is someone whose opinions have set like concrete. For more character words built the same way, see personality adjectives in Japanese.

Is 頑固がんこ always negative?

Mostly it is a complaint, but it can be affectionate, especially for older people with strong principles. The classic image is the 頑固がんこおやじ (がんこおやじ), the stubborn old man who runs a small restaurant his own way and will not change the recipe for anyone. People often say this with a smile.

あの店みせの主人しゅじんは頑固がんこだけど、料理りょうりは最高さいこうだ。 — The owner of that place is stubborn, but the food is the best. (casual, half complaint, half praise) 祖母そぼは頑固がんこで、絶対ぜったいに病院びょういんに行いかない。 — My grandmother is stubborn and will never go to the hospital. (casual, real frustration)

Tone does the work. Said with a sigh, 頑固がんこ is a criticism. Said with a laugh about someone you love, it is closer to "set in their ways".

What is a 頑固がんこな汚よごれ?

頑固がんこな汚よごれ (がんこなよごれ) is a "stubborn stain", a stain that will not come out. It is the same image as English, and you will see it constantly on cleaning products and in TV commercials.

この洗剤せんざいは頑固がんこな汚よごれも落おとせます。 — This detergent can even remove stubborn stains. (polite, advertising language)

This is a nice reminder that 頑固がんこ is really about something that will not move or change, whether it is a person or a coffee stain.

Beyond the basics

What does 頭あたまが固かたい mean?

頭あたまが固かたい (あたまがかたい), literally "hard head", means rigid or inflexible in thinking. It is close to 頑固がんこ but focuses on how someone thinks: they cannot accept new ideas or other ways of doing things.

部長ぶちょうは頭あたまが固かたくて、新あたらしいアイデアを聞きいてくれない。 — The department manager is so rigid that he won't listen to new ideas. (casual, a work complaint) 頭あたまが固かたいね。もっと柔軟じゅうなんに考かんがえようよ。 — You're so inflexible. Let's think more flexibly. (casual, friendly teasing)

The opposite is 頭あたまが柔やわらかい (あたまがやわらかい), "a soft head", meaning open-minded and creative. That is a compliment.

What is 意地いじっ張はり?

意地いじっ張はり (いじっぱり) is someone who will not back down because of pride, even when they know they are wrong. It comes from 意地いじ (いじ), "pride" or "willpower", and 張はる (はる), which here means "to hold to something and push it through". The person holds on to their pride so they do not lose face.

意地いじっ張はりだから、絶対ぜったいに謝あやまらない。 — She's so proud and stubborn that she will never apologize. (casual, describing someone) 意地いじを張はらないで、助たすけを頼たのんだら? — Don't be stubborn. Why not ask for help? (casual, gentle advice)

The verb phrase 意地いじを張はる (いじをはる), "to be stubborn out of pride", is as common as the noun. This is the word for the friend who says "I'm fine!" when they clearly are not. The opposite of 意地いじを張はる is 素直すなお, as in 素直すなおに謝あやまりました ("I apologized without making excuses"), and honest in Japanese explains that 素直すなお means open and willing to listen, a different quality from the truthfulness of 正直しょうじき.

How does stubbornness sound in anime?

In anime, 意地いじっ張はり is the core of the tsundere type: a character who likes someone but is too proud to admit it. Other characters often sum them up in one line.

本当ほんとうに意地いじっ張はりだな。 — You're really stubborn, aren't you. (casual male speech, teasing) 頑固がんこなやつだ。 — What a stubborn guy. (rough, used about a rival or a mentor)

You will also hear the phrase 一度いちど言い出いいだしたら聞きかない, "once they say something, they won't listen", used for a character who has made up their mind and cannot be talked out of it. The related 負まけず嫌きらい, "hating to lose", is another favorite; we cover it in 負まけず嫌きらい in Japanese.

How do you say stubborn as a compliment?

Use 粘り強ねばりづよい (ねばりづよい), "persistent", or 芯しんが強つよい (しんがつよい), "strong at the core". These describe the stubbornness you want in a teammate: not giving up, holding firm to your values.

彼女かのじょは粘り強ねばりずよく練習れんしゅうを続つづけた。 — She kept practicing with great persistence. (polite, praising effort) 彼かれは静しずかだけど、芯しんが強つよい人ひとです。 — He is quiet, but he has a strong core. (polite, praising character)

粘ねばる (ねばる) means to be sticky, like 納豆なっとう (なっとう), and by extension to hang on and not quit. In job interviews, 粘り強ねばりづよい is a strength you can claim for yourself. 頑固がんこ is not.

What about 頑かたくな and 強情ごうじょう?

頑かたくな (かたくな) is a written, more serious word for refusing to change, and 強情ごうじょう (ごうじょう) is an old-fashioned word for obstinate. You will see 頑かたくなに拒こばむ (かたくなにこばむ), "to flatly refuse", in news and novels. 強情ごうじょう appears more in older drama and literature than in everyday talk.

彼かれは頑かたくなに説明せつめいを拒きょんだ。 — He flatly refused to explain. (written, news or novel style)

Which "stubborn" do you mean?

Word Reading What kind of stubborn Tone
頑固がんこ がんこ will not change their ways mostly negative, can be affectionate
頭あたまが固かたい あたまがかたい rigid thinking negative
意地いじっ張はり いじっぱり will not back down out of pride negative or teasing
意地いじを張はる いじをはる to be stubborn out of pride negative
粘り強ねばりづよい ねばりづよい will not give up positive
芯しんが強つよい しんがつよい firm inner strength positive
頑かたくな かたくな flatly refusing written, serious

Common mistakes

  • Using 頑固がんこ as praise in a job interview. It sounds like "hard to work with". Say 粘り強ねばりづよい instead.
  • Forgetting the な. It is 頑固がんこな人ひと, not 頑固がんこ人ひと.
  • Using 頑固がんこ for someone who just will not apologize. That pride-driven stubbornness is 意地いじっ張はり, or 意地いじを張はっている.
  • Writing 頭あたまが硬かたい. You will sometimes see it, but the standard spelling is 頭あたまが固かたい.
  • Calling your boss 頭あたまが固かたい to their face. It is a common complaint, but said directly it is rude.

Practice

Show answer

意地いじっ張はり — it is stubbornness driven by pride. 頑固がんこ is more about not changing one's ways.

4. In a job interview, how do you say you are persistent and do not give up?

Show answer

粘り強ねばりづよいです。 — 粘り強ねばりづよい is a positive word for stubbornness you want. 頑固がんこ would sound like a weakness.

頭あたまが固かたい — rigid thinking. This is the pair to question 4: the stubbornness people complain about.

6. On a detergent bottle, what does 頑固がんこな汚よごれ mean?

Show answer

A stubborn stain — a stain that will not come out. 頑固がんこ is about something that will not move or change.

Show answer

芯しんが強つよい — strong at the core. It is praise, unlike 頑固がんこ.
