疑問な

gimon na
At the A1 level, 'gimon-na' might be a bit difficult. Instead, you usually learn 'shitsumon' (question). However, you can think of 'gimon' as the feeling of 'I don't know' or 'Is this true?'. At this stage, you don't need to use 'gimon-na' as an adjective. Just focus on the noun 'gimon' (doubt). For example, 'Gimon ga arimasu' (I have a doubt/question). This is a simple way to start. You might see this word in very simple textbooks when talking about things that are not clear. Remember, 'gimon' is about your brain thinking 'Wait, what?'. It is a very useful word to know even if you don't use the 'na' part yet. Just remember: Gimon = Question/Doubt. It's the feeling you get when you are confused about a fact. As an A1 learner, just recognizing the kanji 疑 (doubt) and 問 (ask) is a great first step. You will see these kanji everywhere in Japan, especially on tests and in news headlines. If you see '疑問', just know it means someone is asking 'Is this really okay?'. Keep it simple and don't worry about the complex grammar yet.
At the A2 level, you start to see 'gimon-na' used to describe things. You might hear 'gimon-na ten' (questionable points). This is useful when you are reading a short story or a simple news article. You are learning to express your opinions more, and 'gimon-na' helps you say 'I'm not sure about this specific part'. For example, if a friend tells you a story that sounds a bit strange, you can say 'Sore wa gimon-na ten ga aru ne' (There are some questionable points in that). It's a step up from just saying 'Wakaranai' (I don't know). It shows you are thinking about the details. You should also learn the difference between 'shitsumon' (a question you ask to learn) and 'gimon' ( a doubt you have because something is strange). A2 learners can use 'gimon' to show they are critical thinkers. Try using it in your diary: 'Kyou no news wa gimon-na ten ga ookatta' (Today's news had many questionable points). This will help you get used to the 'na' adjective structure. It's a very 'smart' sounding word, so using it correctly will make your Japanese sound much better!
As a B1 learner, 'gimon-na' is a key vocabulary word for you. This is the level where you move from simple daily life Japanese to more analytical Japanese. You should be able to use 'gimon-na' to describe theories, plans, and statements. You will often use it in the phrase 'gimon-na ten' (questionable points) or 'gimon-na kasho' (questionable parts). At this level, you are expected to participate in discussions. If you are in a meeting or a classroom, 'gimon-na' is your best friend. It allows you to point out flaws in a polite way. For example, 'Kono keikaku ni wa, gimon-na ten ga ikutsu ka arimasu' (There are several questionable points in this plan). This is much better than saying 'Kono keikaku wa dame desu' (This plan is bad). It opens up a conversation. You should also start to notice how 'gimon-na' is used in newspapers. It often appears in editorials. You are now at the stage where you can understand that 'gimon-na' isn't just about being 'confused', it's about being 'skeptical'. Practice using it with other B1 grammar like '...to omowareru' (it is thought that...) to sound even more natural.
At the B2 level, you should have a firm grasp of 'gimon-na' and be able to distinguish it from 'utagawashii' (suspicious) and 'fushin-na' (suspicious/shady). You will encounter 'gimon-na' in complex texts about politics, economics, and social issues. You should be able to use it to describe abstract concepts, such as 'gimon-na kachi-kan' (questionable values) or 'gimon-na shisou' (questionable ideology). At this level, you are not just identifying 'points' of doubt, but you are evaluating the overall 'questionability' of a situation. You might use it in a debate: 'Sono ronri wa, zentei kara shite gimon-na mono de wa nai deshou ka?' (Isn't that logic questionable from the very premise?). This shows a high level of linguistic sophistication. You should also be comfortable with the noun form 'gimon' in structures like '...ni gimon o teishisuru' (to raise a doubt about...). This is a very formal and powerful expression. B2 learners should also be aware of the 'na' vs 'no' distinction; while 'gimon-na' is common, sometimes 'gimon no' is used in specific set phrases, though 'na' is the standard adjectival form. Your goal is to use 'gimon-na' to provide nuanced critiques of complex topics.
At the C1 level, 'gimon-na' becomes a tool for precise academic and professional critique. You will use it to dissect arguments and identify subtle inconsistencies. You should be able to use it in written reports to describe 'gimon-na dousei' (questionable trends) or 'gimon-na seitousei' (questionable legitimacy). At this level, you are expected to understand the historical and cultural weight of the word. You might encounter it in legal texts where the 'gimon-na' nature of evidence is debated. You should also be able to use it with advanced adverbs like 'hanahada' (extremely) or 'kiwamete' (exceedingly) to express strong skepticism: 'Kiwamete gimon-na hatsugen da' (It is an exceedingly questionable remark). C1 learners should also be able to use 'gimon' in its more philosophical sense, discussing 'gimon-fu' (question marks) in history or science. You are no longer just using the word; you are playing with its nuances to influence your audience. You should also be able to recognize when 'gimon-na' is being used euphemistically in high-level business negotiations to signal a 'no' without actually saying the word. Your mastery of 'gimon-na' reflects your ability to navigate the complex layers of Japanese professional communication.
At the C2 level, your use of 'gimon-na' is indistinguishable from a highly educated native speaker. You use it with perfect timing and nuance. You understand that 'gimon-na' can be used not just for doubt, but as a rhetorical device to lead an audience toward a specific conclusion. You might use it in a keynote speech or a published essay to describe 'gimon-na jidai no chouryuu' (the questionable trends of the era). You are fully aware of its synonyms and can choose 'gimon-na' over 'utagawashii' or 'kaigiteki-na' to achieve a specific tone—perhaps one of objective, cold analysis. You can also use it in creative writing to describe a character's 'gimon-na sonzai-kan' (questionable sense of existence), blending the logical meaning with existential dread. At this level, you also understand the meta-linguistic aspects of the word—how the choice of 'gimon-na' over a more direct word reflects the speaker's social position and intent. You can navigate the most formal 'Keigo' environments and use 'gimon-na' to politely but devastatingly dismantle an opponent's argument. Your command of 'gimon-na' is a testament to your deep integration into the Japanese linguistic and cultural landscape.

疑問な 30秒了解

  • Gimon-na is a na-adjective meaning 'questionable' or 'doubtful', used to highlight logical flaws or unverified information in statements and plans.
  • It is commonly paired with 'ten' (point) to form 'gimon-na ten', a polite way to express skepticism in professional settings.
  • Unlike 'utagawashii', which implies moral suspicion, 'gimon-na' focuses on intellectual or logical uncertainty and is more objective in tone.
  • It is essential for B1 learners to move beyond simple 'I don't know' to more analytical and critical expressions in Japanese.

The Japanese term 疑問な (gimon-na) is a 'na-adjective' (形容動詞) that encapsulates the state of being questionable, doubtful, or uncertain. Rooted in the combination of two powerful kanji— (doubt/suspicion) and (question/inquiry)—it describes situations, statements, or behaviors that invite skepticism or require further clarification. Unlike simple curiosity, gimon-na often carries a nuance that something does not quite add up, suggesting a gap between what is presented and what is true or logical.

Semantic Core
The essence of this word lies in the intellectual evaluation of information. It is less about the emotional feeling of 'worry' and more about the cognitive assessment that a piece of data or a claim is 'unverified' or 'dubious'.
Structural Usage
While 'gimon' is frequently used as a noun (meaning 'a question' or 'a doubt'), adding 'na' transforms it into a descriptor. It is most commonly seen modifying nouns like 'ten' (point), 'kasho' (part), or 'koudou' (behavior).

この計画の妥当性については、非常に疑問な点が多いと言わざるを得ません。

— Regarding the validity of this plan, I must say there are many questionable points.

In a broader context, gimon-na serves as a bridge between objective inquiry and subjective suspicion. When a scientist encounters data that contradicts a known law, they might label it as gimon-na data. Similarly, in a legal or investigative context, a witness's testimony might be described as gimon-na if it lacks consistency. This word is essential for B1 learners because it allows for the expression of critical thinking without necessarily being aggressive. It is a polite yet firm way to signal that one is not fully convinced.

彼の昨日のアリバイには、いくつか疑問な箇所が見受けられる。

— There are several questionable parts found in his alibi from yesterday.
Kanji Breakdown: 疑
The character for 'doubt' (utagau) depicts a person looking around in confusion, unable to decide which path to take. It represents the internal state of hesitation.

そのニュースの真実味は、今のところ疑問なままだ。

— The truth of that news remains questionable for now.

そんな疑問な態度をとると、周りの信頼を失うよ。

— If you take such a questionable attitude, you will lose the trust of those around you.

To summarize, gimon-na is a versatile tool for expressing skepticism in a structured, intellectual manner. It covers everything from minor inconsistencies in a story to major flaws in a scientific theory, making it a cornerstone of analytical Japanese vocabulary.

Using 疑問な (gimon-na) correctly requires understanding its role as a 'na-adjective' and its placement within a sentence. It primarily functions to modify nouns that represent ideas, facts, or behaviors. Unlike 'utagawashii' (which can feel more accusatory or suspicious), gimon-na is often used in professional, academic, or formal discussions to highlight logical inconsistencies.

Common Collocations
The most frequent pairing is 疑問な点 (gimon-na ten), meaning 'questionable points' or 'points of doubt'. Other common pairings include 疑問な箇所 (gimon-na kasho - questionable parts) and 疑問な発言 (gimon-na hatsugen - questionable remarks).

報告書の中に、いくつか疑問な数字が含まれています。

— There are several questionable figures included in the report.

When you want to say 'It is doubtful whether...', the structure usually shifts to the noun form: ...ka wa gimon da. However, when describing a specific entity as being in a state of doubt, the adjective form is used. For example, 'a questionable decision' becomes gimon-na kettei. This distinction is vital for achieving natural-sounding Japanese at the B1 level and beyond.

その政治家の疑問な資金の流れが、メディアで大きく取り上げられた。

— The politician's questionable flow of funds was widely covered in the media.
Levels of Formality
In casual speech, people might just say 'Ayashii' (suspicious). In formal writing, 'Gimon-na' is preferred as it sounds more objective and analytical. It is the language of critique rather than just 'gut feeling'.

この実験結果は、あまりにも完璧すぎて逆に疑問な感じがする。

— These experimental results are too perfect, so they actually feel questionable.

彼は疑問な点があれば、すぐに質問するタイプだ。

— He is the type of person who asks questions immediately if there are any questionable points.

By mastering the adjectival use of gimon, you gain the ability to pinpoint exactly where your uncertainty lies. Whether you are reviewing a contract, analyzing a news story, or discussing a friend's strange behavior, gimon-na provides the precise linguistic scalpel needed for the task.

The word 疑問な (gimon-na) is a staple of Japanese intellectual life. You will encounter it frequently in environments where critical analysis is valued—newsrooms, university lecture halls, corporate boardrooms, and legal proceedings. It is the language of the 'skeptic' and the 'investigator'.

In the News
Journalists often use this word when reporting on government policies or corporate scandals. Headlines might read: 'Questionable Use of Taxpayer Money' (税金の疑問な使途). It signals to the reader that the media is performing its watchdog role.

政府の新しい経済対策には、効果が疑問な部分が多々ある。

— There are many parts of the government's new economic measures where the effectiveness is questionable.

In academic settings, gimon-na is used during peer reviews or Q&A sessions after a presentation. A professor might say, 'Your conclusion is interesting, but your methodology is gimon-na.' This isn't an insult; it's an invitation for the student to defend their logic or provide more evidence. It is a fundamental part of the dialectic process in Japanese higher education.

犯人の動機については、依然として疑問なままだ。

— Regarding the culprit's motive, it remains questionable as ever.
In Business Meetings
When reviewing a contract or a project proposal, a manager might point to a specific clause and say, 'Koko wa gimon-na ten desu ne' (This is a questionable point, isn't it?). It's a way to pause the discussion and focus on a potential risk.

その投資案件は、リターンが疑問なので見送ることにした。

— We decided to pass on that investment project because the returns are questionable.

彼女の疑問な微笑みが、僕の心をかき乱した。

— Her questionable smile disturbed my heart.

Whether you are reading a high-brow editorial in the Asahi Shimbun or listening to a podcast about true crime, gimon-na is the keyword that signals a shift from acceptance to critical evaluation. It is an indispensable part of the 'thinking' person's Japanese vocabulary.

While 疑問な (gimon-na) is a straightforward na-adjective, learners often stumble over its nuances compared to similar words or its grammatical limitations. One of the most common errors is using it when you actually mean 'mysterious' or 'strange'.

Mistake 1: Confusing with 'Fushigi'
Learners often say 'gimon-na genshou' (questionable phenomenon) when they mean 'fushigi-na genshou' (mysterious phenomenon). 'Gimon' implies you suspect something is wrong or illogical. 'Fushigi' implies you are amazed or puzzled by something beyond normal understanding.

× 魔法のような疑問な出来事。
魔法のような不思議な出来事。

— Incorrect: A questionable event like magic. Correct: A mysterious/wonderful event like magic.

Another frequent error involves the misuse of the particle 'ni'. Many learners try to use gimon-na where they should use the verb phrase gimon ni omou (to think of as a doubt/to doubt). You cannot say 'I am gimon-na' to mean 'I have a doubt'. You must say 'Watashi wa gimon ni omou' or 'Gimon ga aru'.

× 私はそのニュースに疑問なです。
私はそのニュースを疑問に思っています。

— Incorrect: I am questionable to that news. Correct: I have doubts about that news.
Mistake 2: Overusing it for 'Question'
If you want to say 'I have a question for the teacher', use 'shitsumon'. If you say 'gimon-na ten ga aru', it sounds like you are challenging the teacher's accuracy. Be careful with the social implications!

先生、この文法について質問があります。(疑問な点と言わない方が無難)

— Teacher, I have a question about this grammar. (Better than saying 'questionable points')

彼の疑問な経歴が、採用の妨げになった。

— His questionable background hindered his hiring.

Finally, avoid using gimon-na for purely physical uncertainty, like 'I'm not sure if it will rain'. In those cases, 'fukakujitsu' (uncertain) or 'wakaranai' is better. Gimon-na is almost always tied to logic, ethics, or truth-claims.

Japanese has a rich vocabulary for expressing doubt. Understanding the subtle differences between 疑問な (gimon-na) and its synonyms will help you choose the right word for the right situation.

疑わしい (Utagawashii)
This is an i-adjective. It is much more 'suspicious' than 'gimon-na'. While 'gimon-na' suggests a logical flaw, 'utagawashii' suggests someone might be doing something wrong or illegal. It has a stronger emotional 'smell' of guilt.
不審な (Fushin-na)
Used primarily for 'suspicious' behavior or people. You see this on 'Wanted' posters or signs warning about 'fushin-sha' (suspicious persons). It is about safety and security rather than logic.

近所で不審な男が目撃された。

— A suspicious man was spotted in the neighborhood. (Not 'gimon-na')

Then there is Ayashii. This is the most casual word for 'fishy' or 'shady'. You use it with friends when you think a deal is too good to be true. Gimon-na is the professional version of Ayashii.

彼の言い分には疑わしい点が多い。

— There are many suspicious points in his argument. (Implies he might be lying)
懐疑的な (Kaigiteki-na)
This means 'skeptical'. It describes a person's mindset. 'Watashi wa kaigiteki da' (I am skeptical). 'Gimon-na' describes the thing being looked at; 'Kaigiteki-na' describes the person looking at it.

多くの専門家が、その新説に懐疑的な見方を示している。

— Many experts are showing a skeptical view toward that new theory.

そのデータの正確性は、依然として疑問な状態にある。

— The accuracy of that data remains in a questionable state.

Mastering these distinctions will make your Japanese sound much more nuanced and precise, allowing you to express exactly what kind of 'doubt' you are feeling.

常见错误

小贴士

Pair with 'Ten'

Always remember 'gimon-na ten'. It is the most natural and frequent way to use this word. If you are unsure how to use 'gimon-na', just add 'ten' after it to describe a specific point of doubt.

Softening Criticism

Use 'gimon-na' to be polite. Instead of saying 'That's a lie', say 'Sono hatsugen ni wa gimon-na ten ga arimasu'. This keeps the conversation professional and avoids making the other person defensive.

Na-Adjective Rule

Don't forget the 'na'. Since it's a na-adjective, it must have 'na' when it comes before a noun. 'Gimon ten' is sometimes used as a compound noun, but 'gimon-na ten' is the standard adjectival form.

Gimon vs Shitsumon

Think of 'Shitsumon' as a 'Question for Learning' and 'Gimon' as a 'Question of Doubt'. This distinction will help you choose the right word in a classroom vs. a debate.

Business Meetings

In meetings, use 'gimon-na' to flag risks. It shows you are being thorough and looking for potential problems in a plan or contract.

News Keywords

When you hear 'gimon' on the news, pay attention! It usually means the reporter is about to explain a scandal or a problem with a new law.

Analytical Essays

If you are writing an essay for the JLPT or a university class, 'gimon-na' is a great word to use in your 'body' paragraphs to analyze different viewpoints.

The 'Gi' of Doubt

Remember the kanji 疑 (Gi). It's in 'utagau' (to doubt). Whenever you see this kanji, think of someone looking around, unsure of what to believe.

Intonation

When you say 'gimon-na', don't sound too aggressive. A calm, flat intonation makes you sound like a logical thinker rather than an angry accuser.

Beyond 'Ayashii'

As you move to B1 level, try to replace 'ayashii' with 'gimon-na' in formal writing. It shows you have a more sophisticated vocabulary.

In a Japanese meeting, saying 'Sore wa gimon desu' is a polite way to say 'I disagree'.

It is better to describe their actions or background as 'gimon-na' rather than the person themselves. Calling a person 'gimon-na hito' sounds like you are questioning their very existence or identity in a strange way. Instead, use 'fushin-na hito' (suspicious person) or 'ayashii hito' (shady person). 'Gimon-na' is more suited for abstract things like ideas or data.

Yes, it is considered a polite and professional way to express doubt. In a business context, it is much more appropriate than saying someone is wrong. It focuses on the 'points' of the argument rather than the person making it. This makes it a key word for maintaining social harmony while being critical.

'Shitsumon' is a question you ask when you want to learn something you don't know. 'Gimon' is a doubt you have because something doesn't seem right or logical. For example, you ask a 'shitsumon' about grammar, but you have a 'gimon' about a politician's strange excuse.

You can say 'Gimon ga arimasu' (I have a doubt) or 'Gimon ni omoimasu' (I think of it as a doubt). You cannot say 'Watashi wa gimon-na desu'. Remember that 'gimon-na' is an adjective used to describe a noun, like 'gimon-na ten' (a doubtful point).

Yes, but it sounds a bit more formal than 'ayashii'. You might use it when talking about the news or a serious topic with friends. For very casual things, like 'I think this milk is bad', you would use 'ayashii' or 'hen' (strange) instead.

No, that would be 'fushigi-na'. 'Gimon-na' implies that something is logically or ethically questionable. 'Fushigi-na' implies wonder, magic, or something that can't be explained. If you see a UFO, it's 'fushigi'; if you see a politician with extra money, it's 'gimon-na'.

The most common are 'ten' (point), 'kasho' (part), 'koudou' (behavior), 'hatsugen' (remark), and 'keireki' (background). These all relate to things that can be analyzed or scrutinized for truth and logic.

Generally, yes. It implies that something is not quite right. However, in science and academia, it is a neutral term used for critical analysis. It's not necessarily an insult, but it does mean that more proof is needed.

No, that's not natural. Use 'fukakujitsu' (uncertain) or just 'wakaranai'. 'Gimon-na' is for things that involve human logic, statements, or intentions. Weather is a natural phenomenon, so it doesn't 'make a claim' that can be questioned.

It is written as 疑問. The first kanji 疑 means 'doubt' and the second 問 means 'question'. Together they represent the act of questioning something because you doubt its truth.
