الشرح 不誠実 in your Level:

At the A1 level, '不誠実' (fuseijitsu) is a very advanced word. Beginners usually learn 'seijitsu' (sincere/honest) first. Think of 'fuseijitsu' as the 'bad' version of 'seijitsu'. It describes someone who is not a good friend because they tell lies or don't do what they said they would do. In simple terms, it means 'not honest' or 'not nice in a sneaky way'. You might not use this word yourself yet, but you might hear it in a simple story or a cartoon where there is a 'bad' character who tricks others. For an A1 learner, it's enough to know that 'fu' at the start of a word often means 'not', so 'fu-seijitsu' means 'not-sincere'. It is a 'na-adjective', so we say 'fuseijitsu na hito' for 'an insincere person'. At this stage, focus on the feeling of the word: it's a heavy, negative word used when someone is disappointed in someone else's behavior. You can compare it to 'warui' (bad), but 'fuseijitsu' is specifically about lying or breaking trust. Remember, Japanese people value 'sincerity' (seijitsu) very much, so this is a very strong word to use about someone.

At the A2 level, you can start to understand '不誠実' (fuseijitsu) as a word to describe people's character in basic conversations or simple texts. You might see it in a drama where someone is angry at their boyfriend or girlfriend. It is more specific than 'warui' (bad). While 'warui' can mean anything from 'bad weather' to 'bad food', 'fuseijitsu' is only about people and their actions. For example, if a friend says they will come to your party but they never show up and don't call you, you might think they are 'fuseijitsu'. You can use the pattern '[Person] wa fuseijitsu desu' to say '[Person] is insincere'. You should also notice that it is often used with 'taido' (attitude). 'Fuseijitsu na taido' means an insincere attitude. This is useful when you are talking about how someone treated you. Even if you don't use it in speaking yet, recognizing it in reading will help you understand the personality of characters in Japanese stories. It's a step up from 'usotsuki' (liar), which is a bit more childish. 'Fuseijitsu' sounds more like an adult's way of describing a lack of trust.

At the B1 level, you should be able to use '不誠実' (fuseijitsu) to describe social and professional situations. This is the level where the word becomes very useful. You can use it to talk about a company that doesn't tell the truth to its customers, or a politician who makes promises they don't intend to keep. At B1, you are learning to express opinions and feelings about more complex topics, and 'fuseijitsu' is perfect for discussing ethics and trust. You should understand that it is a 'na-adjective' and can also be used as a noun. For example, 'Kare no fuseijitsusa ni odoroku' (I am surprised by his insincerity). You can also use it to describe actions: 'fuseijitsu na koui' (an insincere act). It's important to distinguish it from 'fushoujiki' (dishonest). 'Fushoujiki' is often about a specific lie, while 'fuseijitsu' is about the person's overall way of acting and their lack of respect for the relationship. If a business partner is slow to respond and gives vague answers, you might describe their 'taiou' (handling/response) as 'fuseijitsu'. This word helps you sound more sophisticated and precise in your criticisms.

At the B2 level, you should have a firm grasp of the nuances of '不誠実' (fuseijitsu) and be able to use it in debates, formal writing, and nuanced social interactions. You understand that this word carries a significant moral weight in Japanese society. You can use it to analyze characters in literature or discuss corporate social responsibility. For instance, you might write an essay about how 'fuseijitsu na kigyou no taiou' (the insincere response of a corporation) can lead to a loss of brand value. You should also be familiar with the noun form 'fuseijitsu' being used in legal or semi-formal contexts, such as 'fuseijitsu na keiyaku' (an insincere contract/contract made in bad faith). At this level, you should also be able to use the word to describe internal states, like being 'fuseijitsu' to oneself (jibun ni fuseijitsu). You can compare and contrast it with related terms like 'fugiri' (social ingratitude) or 'haishin' (betrayal of trust). You know that calling someone 'fuseijitsu' is a serious matter and should be done with caution, as it attacks the core of their social identity. You can also use it to describe the 'atmosphere' of a negotiation or a relationship.

At the C1 level, your understanding of '不誠実' (fuseijitsu) should be deep and contextual. You can use it to discuss complex ethical dilemmas and philosophical concepts of sincerity. You should be able to recognize the word in high-level literature, legal documents, and academic discussions about Japanese culture and ethics. You understand how 'fuseijitsu' relates to the concepts of 'honne' (true feelings) and 'tatemae' (public face), and how a perceived lack of sincerity can arise from a failure to balance these two correctly. You can use the word in sophisticated constructions, such as 'fuseijitsu no soshiru o manukarenai' (cannot escape the accusation of being insincere). You are also aware of how the word is used in historical contexts, perhaps in discussions of the 'seijitsu' required of a samurai or a modern leader. Your usage of the word is precise, choosing it over 'fushoujiki' or 'haishin' to specifically highlight the moral and emotional breach of trust. You can also use it in a self-reflective way in formal speeches or writing, perhaps acknowledging a 'fuseijitsu na ten' (an insincere point/aspect) in a previous action to show humility and a desire for improvement.

At the C2 level, you have a native-like intuition for '不誠実' (fuseijitsu). You can use it with absolute precision in any context, from the most formal legal proceedings to the most intimate personal conversations. You understand the subtle shades of meaning it takes on when paired with different particles, verbs, and nouns. You can identify 'fuseijitsu' not just in words, but in the 'ma' (pause) of a conversation or the 'me-tsuki' (look in the eyes) of a speaker. You can discuss the word's etymology, linking the 'sei' (誠) to the 'makoto' (truth/sincerity) of Japanese philosophy and explaining how 'fuseijitsu' represents a fundamental breakdown of the social and cosmic order in traditional thought. You can use the word to critique societal trends, such as the 'fuseijitsusa' of modern digital communication. Your ability to use this word extends to irony, sarcasm, and high-level rhetorical devices. You can effectively argue whether a specific action constitutes 'fuseijitsu' or if it is a necessary 'tatemae' for social harmony. You are a master of the word's social power, knowing exactly when to deploy it for maximum impact or when to use a softer alternative to maintain 'wa' (harmony).

不誠実 في 30 ثانية

不誠実 (fuseijitsu) means insincere, dishonest, or untrustworthy. It is the opposite of 'seijitsu' (sincerity).
It is a 'na-adjective' used to describe people, attitudes, or actions that lack moral integrity and transparency.
In Japan, it is a heavy word often used in contexts of broken promises, infidelity, or corporate scandals.
The word carries a strong moral judgment, suggesting the person's 'heart' is not aligned with their duties.

The Japanese word 不誠実 (ふせいじつ - fuseijitsu) is a powerful and multi-layered term that describes a lack of sincerity, integrity, or honesty. In a society where seijitsu (誠実 - sincerity) is considered one of the highest virtues, being labeled as fuseijitsu is a significant social and personal indictment. It is not merely about telling a lie; it encompasses a broader failure to honor one's commitments, a lack of transparency in one's intentions, and a disregard for the trust others have placed in you. Whether in romantic relationships, business dealings, or political discourse, this word strikes at the heart of a person's character.

Core Meaning: The state of being untrustworthy, dishonest, or failing to act with a sincere heart. It often implies a deliberate choice to be deceptive or evasive.
Relational Context: In Japanese culture, relationships are built on mutual trust and 'giri' (obligation). To act in a fuseijitsu manner is to break the invisible social contract that binds people together.

彼は約束を何度も破る、本当に不誠実な男だ。
(He breaks his promises many times; he is a truly insincere man.)

When you use fuseijitsu, you are often describing a pattern of behavior rather than a single mistake. If someone forgets a meeting once, they might just be 'careless' (fuchuui). However, if they consistently avoid responsibility or hide the truth to protect themselves, they are fuseijitsu. In the workplace, this might refer to a company that hides product defects from the public. In a marriage, it is the standard term for infidelity or emotional dishonesty. The word carries a heavy emotional weight, suggesting that the person's 'kokoro' (heart/spirit) is not aligned with their outward actions.

企業の不誠実な対応が、消費者の怒りを買った。
(The company's insincere response earned the anger of consumers.)

Understanding the nuance of fuseijitsu requires looking at its opposite: seijitsu. To be seijitsu is to be earnest, faithful, and devoted. Therefore, fuseijitsu is the active negation of these qualities. It is often used in formal apologies (or rather, to describe the lack of a proper apology) and in legal contexts where 'good faith' is expected but not delivered. It is a word that demands accountability.

Social Implication: Using this word about someone in a public or professional setting is a very serious accusation that can lead to a total loss of 'face' or social standing.

浮気はパートナーに対する最も不誠実な行為だ。
(Cheating is the most insincere act toward a partner.)

Using 不誠実 (fuseijitsu) correctly in Japanese involves understanding its grammatical role as a na-adjective (adjectival noun). This means it can function as a noun or modify other nouns using the particle 'na'. Because it describes a character trait or the quality of an action, it is frequently paired with nouns like 'hito' (person), 'taido' (attitude), or 'koui' (act). Mastering its usage allows you to express deep disapproval or to analyze complex social situations where trust has been breached.

As a Na-Adjective: When modifying a person or an object, use 'na': 不誠実な人 (an insincere person) or 不誠実なやり方 (a dishonest way of doing things).
As a Noun: It can stand alone as a noun, often followed by the copula 'da' or 'desu': 彼の態度は不誠実だ (His attitude is insincere).

そんな不誠実な言い訳は通用しない。
(Such an insincere excuse won't pass/work.)

In more advanced contexts, you will see fuseijitsu used to describe abstract concepts like 'politics' or 'media'. It is a common word in news reports discussing corruption or corporate cover-ups. When used in the negative form, fuseijitsu de wa nai (not insincere), it often acts as a double negative to imply that while someone isn't necessarily a saint, they aren't actively being deceptive either. However, the most common usage remains the direct criticism of a person's behavior in a relationship.

彼は自分に対して不誠実だった。
(He was being insincere/untrue to himself.)

One interesting grammatical nuance is the use of fuseijitsusa (不誠実さ), where the suffix '-sa' turns the adjective into a noun representing the 'degree' or 'quality' of insincerity. For example, 彼の不誠実さに呆れた (I was amazed/disgusted by his level of insincerity). This allows for a more nuanced discussion of the behavior itself rather than just labeling the person.

政治家の不誠実な発言が波紋を広げている。
(The politician's insincere remarks are causing a stir.)

Collocation: Taido (Attitude): Often paired as 'fuseijitsu na taido' to describe someone's dismissive or dishonest manner during a conflict.

質問に対して不誠実な回答しか得られなかった。
(I could only get insincere answers to my questions.)

You will encounter 不誠実 (fuseijitsu) in a variety of settings, ranging from the highly dramatic to the strictly professional. Because it touches on the fundamental Japanese value of sincerity, it is a staple in media and literature. In daily life, while you might not say it directly to someone's face unless in a serious confrontation, you will certainly hear it used to describe others in gossip, news analysis, or relationship advice.

In TV Dramas and Movies: This word is the 'go-to' accusation in romantic dramas. When a character discovers their partner has been lying or cheating, they often scream, 'Anata wa fuseijitsu yo!' (You are insincere/faithless!). It highlights the betrayal of trust.
In News and Journalism: Journalists use it to describe government officials who dodge questions or companies that handle scandals poorly. A 'fuseijitsu na taiou' (insincere handling) is a common headline when a public figure's apology feels staged or insufficient.

ワイドショーでは、芸能人の不誠実な交際が議論されている。
(On talk shows, celebrities' insincere relationships are being discussed.)

In the business world, fuseijitsu is used in legal documents and formal complaints. If a vendor fails to deliver goods as promised and offers weak excuses, the client might describe the vendor's actions as fuseijitsu. It serves as a warning that the business relationship is in jeopardy. It is also used in performance reviews to describe an employee who lacks dedication or who is deceptive about their progress.

契約違反は、ビジネスにおいて最も不誠実なことです。
(Breach of contract is the most insincere thing in business.)

Social media and internet forums (like 2channel or X/Twitter) are also places where this word thrives. Users often call out influencers or public figures for 'fuseijitsu' behavior when their public persona doesn't match their private actions. It is a tool for social policing in the digital age. In literature, especially in 'I-novels' (Shishosetsu), the protagonist often reflects on their own fuseijitsusa, exploring the gap between their desires and their moral obligations.

彼は自分の過ちを認めない、不誠実な人間だ。
(He is an insincere person who doesn't admit his own mistakes.)

While 不誠実 (fuseijitsu) might seem straightforward as 'insincere', English speakers often make mistakes by using it too broadly or confusing it with similar-sounding but contextually different Japanese words. Understanding these pitfalls is key to sounding natural and avoiding unintended offense.

Mistake 1: Confusing with 'Shitsurei' (Rude): 'Shitsurei' refers to a lack of manners (e.g., forgetting to bow). 'Fuseijitsu' refers to a lack of moral integrity. Calling someone 'fuseijitsu' for a minor etiquette slip is way too harsh.
Mistake 2: Using it for Accidental Lies: If someone gives you the wrong directions because they were mistaken, they are not 'fuseijitsu'. They are just wrong. 'Fuseijitsu' implies a level of intent or a character flaw.

❌ 間違った時間を教えるのは不誠実だ。
(Telling the wrong time is insincere. - Too strong if it was an accident.)

Another common mistake is overusing the word in casual settings. Fuseijitsu is a heavy word. If a friend is 5 minutes late to a movie, calling them fuseijitsu sounds overly dramatic and might damage the friendship. Instead, use 'darashinai' (sloppy/undisciplined) or 'ruzu' (loose with time). Reserve fuseijitsu for when they lie about why they were late or if they consistently blow you off without a care.

✅ 彼は時間にルーズだが、不誠実ではない。
(He is loose with time, but he isn't insincere.)

Learners also sometimes struggle with the difference between fuseijitsu and fushoujiki (dishonest). While they overlap, fushoujiki is more about the specific act of not telling the truth. Fuseijitsu is about the general lack of commitment and 'faith' in a relationship or duty. You can be 'shoujiki' (honest) about being 'fuseijitsu'—for example, a person who honestly admits they have no intention of keeping their promise is being honest, but they are still being fuseijitsu because they are failing their obligation.

不注意なミスを不誠実と呼ぶのは間違いだ。
(It is a mistake to call a careless error 'insincerity'.)

To truly master the nuances of 不誠実 (fuseijitsu), it is helpful to compare it with other words that describe negative character traits or dishonest behavior. Japanese has a rich vocabulary for social conduct, and choosing the right word can change the entire tone of your sentence.

不正直 (Fushoujiki): Meaning 'dishonest'. This is the direct opposite of 'shoujiki' (honest). It focuses specifically on the act of lying or hiding the truth. While fuseijitsu is about character and faith, fushoujiki is about the facts.
いい加減 (Ii kagen): Meaning 'irresponsible' or 'half-baked'. This is used for someone who does sloppy work or doesn't take things seriously. It's less about moral malice and more about a lack of effort. A student who forgets their homework is 'ii kagen', not 'fuseijitsu'.

彼は仕事がいい加減だが、根は良い人だ。
(His work is sloppy, but he is a good person at heart.)

In the context of relationships, you might hear uwayaki (浮気 - cheating/fickleness) or furin (不倫 - adultery). These are specific acts, whereas fuseijitsu is the underlying character flaw that leads to those acts. If you want to describe someone who is generally untrustworthy in their speech, you might use detarame (nonsense/irresponsible speech) or usotsuki (liar).

不義理 (Fugiri): Meaning 'lack of gratitude' or 'failure to do one's duty'. This is specifically about social obligations. If someone helps you move and you don't even thank them, that is 'fugiri'. It overlaps with fuseijitsu but is narrower in scope.

恩人に挨拶もしないのは不義理だ。
(It is ungrateful/dishonorable not to even greet your benefactor.)

For a more formal or academic tone, you might use haishin (背信 - breach of trust/betrayal). This is often used in legal terms like 'haishin koui' (breach of trust). It is much more clinical than the emotionally charged fuseijitsu. When choosing between these words, consider whether you are criticizing the person's heart (fuseijitsu), their specific words (fushoujiki), their effort (ii kagen), or their social duty (fugiri).

その態度は不誠実というよりは、単なる無知だ。
(That attitude is less insincerity and more simple ignorance.)

How Formal Is It?

The middle kanji '誠' (sei) is the same character used on the flags of the Shinsengumi, the famous samurai police force of the late Edo period. For them, 'sincerity' was a life-and-death matter.

سهل الخلط

不誠実 vs 不正直 (fushoujiki)

Both mean 'dishonest'.

Fushoujiki is specifically about not telling the truth. Fuseijitsu is about a lack of sincerity and commitment in a broader sense.

テストでカンニングをするのは不正直だ。浮気をするのは不誠実だ。

不誠実 vs いい加減 (ii kagen)

Both describe negative work/behavior.

Ii kagen is about being sloppy or irresponsible. Fuseijitsu is about being deceptive or breaking trust.

不誠実 vs 不徳 (futoku)

不誠実 vs 不義理 (fugiri)

Both involve failing others.

Fugiri is specifically about social obligations and gratitude. Fuseijitsu is about the internal lack of sincerity.

不誠実 vs 背信 (haishin)

نصائح

Avoid overusing with friends

Calling a friend 'fuseijitsu' for a small mistake is like calling them 'morally bankrupt' in English. It's very heavy.

Use with 'taido'

If you want to criticize someone's behavior without attacking their whole soul, say 'fuseijitsu na taido' (insincere attitude).

Sincerity is key

In Japan, showing 'seijitsu' (sincerity) is often more important than being right. 'Fuseijitsu' is the ultimate social sin.

Pitch Accent

Keep the pitch high on 'sei-i-ji' to sound more natural.

Look for the 'Fu'

Whenever you see '不' at the start of a kanji word, look for the positive word that follows to understand the meaning.

Stroke Order

Pay attention to the stroke order of '誠'. The 'speech' radical (言) always comes first.

News Context

When you hear 'fuseijitsu' in the news, it's almost always followed by 'taiou' (handling/response).

Pair with 'Giri'

Think of 'fuseijitsu' as the failure to uphold 'giri' (social obligation).

Bad Faith

In a legal context, 'fuseijitsu' is essentially the Japanese equivalent of 'acting in bad faith'.

Betrayal

If someone describes a breakup as being due to 'fuseijitsu', it usually implies lying or cheating.

احفظها

وسيلة تذكّر

Think of 'Fu' as 'Fooled you'. 'Sei' as 'Saying'. 'Jitsu' as 'Just the truth'. So, 'Fu-Sei-Jitsu' is 'Fooled you by NOT saying just the truth'.

ربط بصري

Imagine a person wearing a 'happy' mask, but behind the mask, they are holding a set of crossed fingers and a bag of stolen gold.

Trust Lies Promises Heart Betrayal Character Ethics Apology

تحدٍّ

Write three sentences describing a character in a movie you hate using the word 'fuseijitsu'. Try to use it as both a na-adjective and a noun.

أصل الكلمة

Composed of three kanji characters: '不' (fu - negation), '誠' (sei - sincerity/truth), and '実' (jitsu - reality/fruit). The root 'seijitsu' comes from traditional Confucian ethics which emphasize sincerity as a core virtue.

المعنى الأصلي: Not having a sincere heart or true actions. A state where one's words and heart do not match reality.

Sino-Japanese (Kango).

السياق الثقافي

Calling someone 'fuseijitsu' is a direct attack on their character. Use it only when you are certain and prepared for a serious conflict.

English speakers might use 'dishonest' or 'unreliable', but 'insincere' is the closest match for the emotional weight of 'fuseijitsu'.

The term is often used in political scandals in Japan, such as the 'Kake Gakuen' scandal, to describe government responses. In the novel 'Kokoro' by Natsume Soseki, themes of sincerity and insincerity are central to the protagonist's struggle. Japanese celebrity 'apology press conferences' (shazai kaiken) are often critiqued by the public as being 'fuseijitsu'.
