解析 裏付け in your Level:

At the A1 level, you don't need to use the word 'urazuke' yourself, but you should understand it means 'proof' or 'support.' Imagine you tell a story, and your friend asks, 'Is it true?' The things that make it true are the 'urazuke.' In simple Japanese, we might use 'shōko' (proof) instead. 'Urazuke' is like the 'backing' of a piece of paper that makes it strong. At this level, just remember that 'urazuke' is a formal way to talk about why something is true. You might see it in simple news headlines or hear it in detective shows. It is a noun, and it usually appears with 'ga aru' (there is) or 'nai' (there isn't). For example, 'Urazuke ga nai' means 'There is no proof.' This is a good word to recognize to start understanding more serious Japanese conversations.

At the A2 level, you can begin to distinguish between 'urazuke' and 'shōko.' While 'shōko' is any kind of proof, 'urazuke' is specifically the support that confirms a story. Think of it as 'back-up.' If you say you were at school, and your teacher says they saw you, the teacher's word is the 'urazuke' (corroboration) for your story. You will often see this word in news reports about the police. For example, 'Keisatsu wa urazuke o toru' (The police are getting corroboration). This 'toru' (to take/get) is a very common verb to use with 'urazuke.' It shows an active effort to find the truth. You might also hear it in business when someone asks for a reason for a plan. It’s a step up in vocabulary that makes you sound more professional.

At the B1 level, you should be able to use 'urazuke' in your own sentences, especially in formal or semi-formal contexts. This word is essential for discussing theories, news, and business proposals. You should understand the structure '...no urazuke to naru' (to become the corroboration for...). For example, 'Kono dēta wa riron no urazuke to naru' (This data serves as corroboration for the theory). You should also be comfortable with the verb form 'urazukeru' (to corroborate). This allows you to say 'Dēta ga riron o urazukeru' (The data corroborates the theory). At this level, using 'urazuke' shows that you understand the importance of factual support and logical reasoning in Japanese communication. It is a key word for passing the JLPT N3 or N2 levels.

At the B2 level, you are expected to understand the nuance of 'urazuke' as structural support. It’s not just any evidence; it’s the evidence that specifically reinforces a claim from 'behind' (ura). You should recognize its use in complex sentences involving passive voice, such as '...ni yotte urazukerarete iru' (is corroborated by...). You should also be able to use it in professional settings, such as during a meeting when you need to provide the 'urazuke' (the logic and data) for your sales targets. You can contrast it with 'konkyo' (grounds) and 'shōko' (evidence) to express precise meanings. For example, you might explain that while you have the 'konkyo' (reasoning), you are still looking for the 'urazuke' (factual confirmation). This level of precision is vital for business and academic Japanese.

At the C1 level, you should have a deep understanding of 'urazuke' and its related compounds and formal alternatives. You should be familiar with terms like 'urazuke-sōsa' (corroborative investigation) and 'urazuke-shiryō' (supporting documents). You should also be able to use the word in abstract philosophical or legal discussions. For instance, discussing the 'urazuke' of a currency (what backs a currency's value) or the historical 'urazuke' for a specific cultural narrative. You should be able to use 'urazuke' to critique arguments, noting where the 'urazuke' is weak or insufficient. At this level, you should also be aware of more literary synonyms like 'shōsa' (proof/verification) and know when to use them instead of the more common 'urazuke' to match the tone of high-level literature or legal writing.

At the C2 level, 'urazuke' is a tool for nuanced and sophisticated discourse. You understand its etymological roots in garment-making and how that metaphor applies to strengthening an argument. You can use it fluently in high-stakes environments, such as legal defense, advanced scientific research, or political analysis. You are capable of navigating the subtle differences between 'urazuke,' 'shōko,' 'konkyo,' and 'ebidensu' with native-like intuition. You can identify when 'urazuke' is used rhetorically to add weight to a statement and when it is being used technically to refer to specific data sets. Your ability to use the verb form 'urazukeru' in complex, multi-clause sentences is flawless. At this stage, 'urazuke' is not just a vocabulary word; it is a conceptual framework you use to build and deconstruct complex Japanese arguments.

裏付け 30秒了解

Urazuke means 'corroboration' or 'backing' that confirms a claim or theory.
It is a formal noun often used in news, law, business, and academic contexts.
It differs from 'shōko' (evidence) by focusing on the act of supporting a claim.
Commonly paired with 'toru' (to obtain) or used as the verb 'urazukeru' (to corroborate).

The Japanese word 裏付け (urazuke) is a sophisticated noun that translates primarily to 'evidence,' 'support,' or 'corroboration.' At its linguistic core, it is composed of two parts: 裏 (ura) meaning 'back' or 'reverse side,' and 付け (zuke) from the verb tsukeru, meaning 'to attach' or 'to fix.' Conceptually, it refers to the act of attaching a lining to a garment to make it stronger, or providing a 'back' to a statement so it doesn't collapse under scrutiny. In modern Japanese, it is used to describe the factual foundation that makes a claim, theory, or testimony credible. Unlike the general word for evidence, 証拠 (shōko), which can be any physical object or testimony, 裏付け specifically implies the process of verification and the strengthening of a hypothesis through secondary data.

Nuance: It suggests a structural support. If a story has 'urazuke,' it means someone has checked the facts from behind the scenes to ensure the story holds water.

その主張には科学的な裏付けが欠けている。
(Sono shujō ni wa kagakuteki na urazuke ga kakete iru.)
That claim lacks scientific corroboration.

You will frequently encounter this word in news reports, police procedurals, and academic writing. For instance, a detective might say they are looking for urazuke-sōsa (corroborative investigation) to confirm a suspect's alibi. In a business context, a proposal is only as good as the market data that provides its urazuke. It signifies a transition from a mere idea to a proven fact. When people use this word, they are often looking for the 'why' and 'how' behind a statement, seeking the tangible proof that substantiates an intangible claim. It is a word of high integrity and reliability.

Common Verb Pairings: 裏付けをとる (to obtain corroboration), 裏付ける (to corroborate - verb form), 裏付けがある (to have support).

警察は証言の裏付けを慎重に進めている。
(Keisatsu wa shōgen no urazuke o shinchō ni susumete iru.)
The police are carefully proceeding with the corroboration of the testimony.

In interpersonal communication, requesting urazuke is a polite but firm way to ask for proof. It doesn't necessarily imply that you think the person is lying, but rather that for the sake of accuracy or professionalism, more data is required. It is a hallmark of critical thinking in Japanese culture, emphasizing the importance of objective reality over subjective assertion. Whether you are discussing history, science, or daily news, urazuke is the gold standard for truth-seeking.

理論を補強するための裏付けとなるデータが必要です。
(Riron o hokyō suru tame no urazuke to naru dēta ga hitsuyō desu.)
We need data that serves as corroboration to reinforce the theory.

Using 裏付け effectively requires understanding its grammatical flexibility. As a noun, it often acts as the object of verbs like toru (to take/obtain) or kaku (to lack). When you say 裏付けをとる (urazuke o toru), you are describing the active process of verifying information. This is a standard phrase in journalism and detective work. If you say 裏付けがある (urazuke ga aru), you are stating that the evidence already exists, making the claim solid. Conversely, 裏付けがない (urazuke ga nai) describes a 'groundless' or 'unsubstantiated' rumor or statement.

Grammar Tip: When using it as a modifier, use 'no' (の) or 'to naru' (となる). For example, 'urazuke no nai hanashi' (a story without backing) or 'urazuke to naru shōko' (evidence that serves as corroboration).

彼の発言を裏付ける証拠は見つからなかった。
(Kare no hatsugen o urazukeru shōko wa mitsukaranakatta.)
No evidence was found to corroborate his statement.

The verb form 裏付ける (urazukeru) is also highly productive. It is a transitive verb, meaning it takes a direct object (the thing being corroborated). For example, 'jijitsu o urazukeru' (to corroborate the facts). This form is often used in the passive voice in academic papers: 'kono riron wa dēta ni yotte urazukerarete iru' (this theory is corroborated by data). This highlights the objective nature of the word—it is the data that does the supporting, removing the subjectivity of the researcher.

十分な裏付けなしに結論を出すのは危険だ。
(Jūbun na urazuke nashi ni ketsuron o dasu no wa kiken da.)
It is dangerous to draw a conclusion without sufficient corroboration.

Furthermore, urazuke can be paired with nouns to form compounds. Urazuke-shiryō (supporting documents/materials) is common in formal meetings. Urazuke-sōsa (corroborative investigation) is a staple of crime fiction. Understanding these patterns allows you to recognize the word's function quickly. It essentially functions as a 'validation stamp' in Japanese discourse. If something is 'urazuke-sumi' (already corroborated), it is considered a settled fact. Mastery of these sentence patterns will elevate your Japanese from basic communication to professional-level fluency.

その新説は、最新の観測データによって強力な裏付けを得た。
(Sono shinsetsu wa, saishin no kansoku dēta ni yotte kyōryoku na urazuke o eta.)
The new theory gained strong corroboration through the latest observation data.

You are most likely to hear 裏付け (urazuke) in settings where truth and accuracy are paramount. In the world of Japanese news broadcasting (NHK, etc.), journalists frequently use it when reporting on investigations. They might say, 'The police are currently seeking urazuke for the suspect's statement.' This implies that while the suspect has said something, the authorities do not yet treat it as a fact. This distinction is crucial in a society that values objective verification over hearsay.

Domain: Legal/Police: Used in 'urazuke-sōsa' to describe the process of checking alibis or finding physical evidence to match a confession.

アリバイの裏付けが取れれば、彼は釈放されるだろう。
(Aribai no urazuke ga torereba, kare wa shakuhō sareru darō.)
If corroboration for his alibi is obtained, he will likely be released.

In a corporate environment, urazuke is the backbone of decision-making. During a project proposal, a manager might ask, 'What is the urazuke for these projected sales figures?' They are looking for market research, historical data, or competitive analysis. Using this word shows that you are thinking logically and expect others to do the same. It is less about 'proof' in a confrontational sense and more about 'justification' in a professional sense.

You will also find it in academic journals. Researchers must provide urazuke for their findings through experiments or citations. If a paper is criticized for having 'insufficient urazuke,' it means the methodology or the data doesn't fully support the conclusions. In this sense, urazuke is the bridge between a hypothesis and a proven law. Even in casual conversations about rumors, someone might say, 'That's just a rumor; there's no urazuke,' indicating they don't believe it yet.

その噂には何の裏付けもありません。
(Sono uwasa ni wa nan no urazuke mo arimasen.)
There is no corroboration whatsoever for that rumor.

Domain: Business/Finance: Used when discussing the 'backing' of a currency or the 'reasoning' behind a financial forecast.

Finally, in the context of history and archaeology, urazuke refers to the physical remains or documents that confirm historical accounts. If an ancient text mentions a city, and archaeologists find the ruins, that is the urazuke. It is a word that spans across time, connecting words to the physical world.

One of the most common mistakes learners make is confusing 裏付け (urazuke) with 証拠 (shōko). While both can be translated as 'evidence,' they are used differently. Shōko is the general term for any proof (a fingerprint, a knife, a photo). Urazuke is the *act* or *state* of that proof supporting a claim. You 'obtain' urazuke to make a claim stronger. Using shōko when you mean 'corroboration' can make your Japanese sound a bit simplistic or overly dramatic, like a TV show detective rather than a professional.

Common Error: Saying 'Urazuke o misete' (Show me the corroboration) is rare. Usually, you say 'Shōko o misete' (Show me the evidence). 'Urazuke' is more about the logical support behind the scenes.

❌ この写真が私の裏付けです。
✅ この写真が私の主張の裏付けとなります。
(The second sentence is more natural: This photo serves as corroboration for my claim.)

Another mistake is the confusion between 根拠 (konkyo) and urazuke. Konkyo refers to the 'grounds' or 'basis'—the starting point of a thought. Urazuke is the 'backing'—the secondary material that proves the thought. If you have a theory, the konkyo is your reasoning, and the urazuke is the experimental data that proves your reasoning was correct. Using them interchangeably can muddy your logic in high-level discussions.

Learners also sometimes misuse the particle 'ni.' It should be 〜の裏付け (no urazuke) or 〜を裏付ける (o urazukeru). For example, 'shōgen no urazuke' (corroboration of testimony), not 'shōgen ni urazuke.' Paying attention to these small particles will make your usage sound much more native and precise.

❌ 理論に裏付けする。
✅ 理論を裏付ける。
(Directly corroborate the theory.)

Lastly, avoid using urazuke in very trivial, daily situations. If your friend says they ate an apple, you wouldn't ask for urazuke. That would sound overly formal and suspicious. Stick to shōko or just ask 'Hontō?' (Really?) in casual settings. Urazuke is best reserved for situations where the truth has serious implications, such as work, law, or science.

Understanding the synonyms of 裏付け (urazuke) helps you choose the right word for the right level of formality and context. While urazuke is the most common word for 'corroboration,' several other terms share its semantic space. The most frequent is 証拠 (shōko), which is the broad term for evidence. If urazuke is the 'backing,' shōko is the 'proof' itself. In a courtroom, physical items are shōko, but the witness testimony that links them to the crime is the urazuke.

裏付け (Urazuke) vs. 証拠 (Shōko): Urazuke is the logical support or verification process; Shōko is the physical or tangible proof.

Another important alternative is 根拠 (konkyo). This word translates to 'grounds,' 'basis,' or 'foundation.' It is used when discussing the reasoning behind an opinion. If you say, 'I think it will rain,' and someone asks for your konkyo, they want to know why you think that (e.g., 'The clouds are dark'). If you then show them a barometer reading, that barometer reading is the urazuke for your konkyo.

裏付け (Urazuke) vs. 根拠 (Konkyo): Konkyo is the 'why' (the reason); Urazuke is the 'what' (the corroborating data).

その統計データが主張の有力な根拠となっている。
(Sono tōkei dēta ga shujō no yūryoku na konkyo to natte iru.)
That statistical data serves as a strong basis for the claim.

In business and tech, the loanword エビデンス (ebidensu) is increasingly popular. It is used almost exactly like urazuke but sounds more modern and 'global.' You might hear it in IT companies or medical fields. However, urazuke remains more versatile and is preferred in formal writing and news reporting. Finally, 証左 (shōsa) is a very formal, literary term for 'proof' or 'verification,' often seen in historical texts or legal documents.

常见错误

Using 'urazuke suru' instead of 'urazukeru'. → 理論を裏付ける。

For physical objects, 'shōko' is more natural. 'Urazuke' is for the logical support of a claim.

小贴士

Use in Reports

When writing a report, always include a section for 'urazuke-shiryō' (supporting materials) to increase your credibility.

Verb vs. Noun

Remember that 'urazuke' is a noun. If you want to say 'to corroborate,' use the verb 'urazukeru' or the phrase 'urazuke o toru.'

Structural Support

Think of 'urazuke' as a structural support. It's not just a sign; it's the pillar holding up the roof of your argument.

Synonym Choice

Use 'shōko' for physical objects and 'urazuke' for the logical verification of a story.

Polite Questioning

Asking for 'urazuke' is a professional way to say 'I need more than just your word for this.'

News Keywords

In Japanese news, 'urazuke' often appears when an investigation is ongoing but not yet concluded.

Garment Metaphor

Remember the 'lining' of a kimono. A claim without 'urazuke' is like a thin shirt that might rip easily.

Kanji Practice

Practice the kanji '裏' (ura). It’s common and useful for many words like 'ura-guchi' (back door) and 'ura-gawa' (reverse side).

Social Integrity

In Japan, providing 'urazuke' is a sign of respect for the listener's time and intelligence.

Thesis Support

In a thesis, ensure every major claim is 'urazukerarete iru' (corroborated) by a reliable source.

记住它

记忆技巧

Think of 'Ura' (Back) and 'Zuke' (Attach). To make a story strong, you must 'attach a back' to it so it doesn't fall over. Urazuke is the 'backing' of your argument.

视觉联想

Imagine a thin piece of paper (a claim) that becomes a thick book (a fact) when you glue a piece of cardboard (urazuke) to the back of it.

Word Web

裏 (Back) 付け (Attach) 証拠 (Evidence) 根拠 (Basis) 事実 (Fact) 確認 (Check) 信頼 (Trust) 補強 (Reinforce)

挑战

Try to find one news article today in Japanese and look for the word '裏付け'. If you can't find it, write a sentence about your favorite hobby using '裏付け' (e.g., 'My hobby is backed by 10 years of practice').

词源

The word comes from the combination of 'ura' (back/lining) and 'tsuke' (attaching). It originally referred to the practice of sewing a lining onto the back of a piece of cloth or a garment to make it more durable and keep its shape.

原始含义： Attaching a lining to a garment to reinforce it.

Japonic (Yamato Kotoba origin for the components).

文化背景

This is a neutral, professional word. It is not offensive, but using it in casual settings can make you sound like a suspicious detective or a strict boss.

In English, we use 'corroboration' or 'backing.' 'Urazuke' is slightly more common in everyday Japanese business than 'corroboration' is in everyday English business, where we might just say 'data' or 'proof.'

Detective Conan (often used during the deduction phase). Aibo (popular Japanese police drama where 'urazuke' is frequently mentioned). NHK News (Standard term for investigative reporting).

Not exactly. While it can be translated as 'evidence,' it specifically means 'corroboration' or 'backing.' 'Shōko' is the general word for evidence. 'Urazuke' is the evidence that supports a specific statement or theory.

Yes, but it sounds a bit serious. You might use it when talking about a rumor you don't believe, asking 'Urazuke aru no?' (Is there any proof?). For daily things like 'Did you eat lunch?', it is too formal.

'Konkyo' is the 'reason' or 'grounds' for an opinion. 'Urazuke' is the 'data' or 'fact' that proves that reason is correct. For example, 'I think it's cold' (opinion) because 'the thermometer says 0 degrees' (urazuke).

The verb is 'urazukeru.' You use it with the particle 'o.' For example: 'Dēta ga riron o urazukeru' (The data corroborates the theory).

Very much so. It is used to ask for the data or logic behind a business plan or sales forecast. 'Kono sūji no urazuke wa?' means 'What is the backing for these numbers?'

No, Japanese nouns don't change for plural. 'Urazuke' can mean one piece of corroboration or many.

It is a legal/police term meaning 'corroborative investigation.' It's the process of checking if a suspect's story matches the facts.

Yes. For example, 'His success was backed by hard work' (Kare no seikō ni wa doryoku no urazuke ga atta). It means his success was not just luck.

'Ebidensu' is a modern loanword used mostly in IT and medical business. 'Urazuke' is more traditional and widely understood across all formal contexts.

It is written as 裏付け. The first kanji is 'ura' (back) and the second part 'zuke' uses the 'okurigana' (hiragana attached to kanji) '付け'.
