Explicación 明らかにする in your Level:
At the A1 level, you don't need to use this word yet, but you might see the word 'Akiraka' (clear). Think of it like the word 'clear' in English. When the sun is out, the sky is 'clear.' When a window is clean, it is 'clear.' In Japanese, we use the adjective 'Akiraka' for things that are very easy to see or understand. For example, 'It is clear that he likes apples.' At this level, just remember that 'Akiraka' means 'obvious' or 'clear.' You will mostly use simpler words like 'wakaru' (to understand) or 'shiru' (to know). If you see 'Akiraka ni suru,' just think: 'Someone is making something easy to see.' It is like showing a picture to a friend so they can see what you are talking about. Focus on the 'bright' feeling of the first kanji (明), which combines the sun and the moon.

At the A2 level, you can start using 'Akiraka ni suru' in simple sentences to show that you are explaining something clearly. Instead of just saying 'I will tell you,' you can say 'I will make it clear.' This sounds a bit more serious and helpful. For example, if you are planning a party, you can say 'I will make the time and place clear' (Jikan to basho o akiraka ni shimasu). It means you will give all the details so no one is confused. You might also hear it in simple news stories about weather or local events. Remember the structure: [Thing] + o + akiraka ni suru. It is a good step up from 'setsumei suru' when you want to emphasize that you are removing confusion. You are becoming more precise with your Japanese!

As a B1 learner, 'Akiraka ni suru' is a key vocabulary word for you. You should be able to use it in both speaking and writing, especially when discussing news, school projects, or work tasks. At this level, you understand that it means more than just 'explaining.' It implies 'revealing' or 'disclosing' information that wasn't known before. You can use it to talk about scientific discoveries (The study clarified the results) or personal decisions (He made his plans clear). You should also be comfortable with the passive form 'Akiraka ni sareru' (It was revealed that...), which is very common in reading passages. This word helps you sound more professional and allows you to participate in discussions about facts and evidence rather than just opinions.
At the B2 level, you should master the nuances of 'Akiraka ni suru' versus its synonyms like 'Meikaku ni suru' or 'Kaimei suru.' You will use this verb to describe complex social issues, corporate strategies, or legal findings. You should be able to use it with abstract objects like 'the root cause of the problem' (mondai no konponteki riyuu) or 'the political stance' (seijiteki tachiba). You will encounter this word in editorials and formal debates. You should also be able to use the nominalized form 'Akiraka ni suru koto' as a subject or object in a sentence. At this stage, your usage should reflect an understanding that 'Akiraka ni suru' often involves a sense of public accountability or the resolution of a significant unknown.

At the C1 level, 'Akiraka ni suru' is a tool for sophisticated analysis. You use it in academic writing to define the 'elucidation' of complex theories or historical events. You understand its rhetorical power—how using this verb can frame a discovery as an objective truth. You are also familiar with its use in high-level literature where the 'revelation' of a character's true nature or a plot point is described. You can distinguish between 'Akiraka ni suru' (making clear) and 'Tsumabiraka ni suru' (making clear in great detail), the latter being a more literary and advanced version. You use the verb to navigate nuanced discussions where the boundary between what is known and what is hidden is critical to the argument.

You can use the word to describe the 'revelation' of truth in a way that carries gravitas. You are also aware of how the word can be used ironically or strategically in political rhetoric to suggest a transparency that might not fully exist. Your ability to use this verb, its passive, causative, and literary variants (like 'Akiraka ni seshimeru') allows you to express the finest shades of meaning regarding the disclosure and verification of information in any context.

明らかにする en 30 segundos

  • A formal verb phrase meaning 'to clarify' or 'to reveal' previously unknown or vague information.
  • Commonly used in news, business, science, and legal contexts to establish objective facts.
  • Follows the transitive pattern 'Object o Akiraka ni suru' and is often seen in the passive form 'Akiraka ni sareru'.
  • Derived from 'Akiraka' (clear) and 'Suru' (to make), emphasizing the result of achieving clarity.

The Japanese verb 明らかにする (Akiraka ni suru) is a cornerstone of formal and semi-formal communication, functioning as a bridge between the unknown and the known. At its core, it means 'to clarify,' 'to reveal,' or 'to make something clear.' It is composed of the adjective akiraka (clear/evident) and the causative-like construction ni suru (to make into). This word isn't just about turning on a light in a dark room; it is about the intellectual or social process of bringing facts, intentions, or truths into the light of public or personal understanding.

Semantic Range
This verb covers a wide spectrum from simple explanation to high-stakes investigative revelation. In a business meeting, it might be used to clarify a project's goals. In a police report, it refers to uncovering the truth of a crime. In scientific contexts, it describes the process of elucidating a complex natural phenomenon.
Social Nuance
Using this word implies a certain level of responsibility. When a person or organization 'makes something clear,' there is an expectation of accuracy and finality. It is more formal than simply saying 'setsumei suru' (to explain), as it focuses on the resulting state of clarity rather than just the act of talking.

政府は新しい政策の全貌を明らかにした。
(The government clarified the full picture of the new policy.)

In everyday Japanese life, you will encounter this word frequently in news broadcasts (NHK), newspapers (Asahi, Yomiuri), and corporate press releases. It carries an objective weight. For example, when a company 'makes clear' its financial losses, it is not just chatting about them; it is making a formal disclosure. The kanji 明 (bright) combined with 白 (white) in its archaic form, or simply the concept of 'brightness' and 'clarity,' suggests that the subject was previously shrouded in 'darkness' or 'confusion.'

Psychologically, Akiraka ni suru provides a sense of closure. In literature, it is the moment the detective reveals the killer's identity. In science, it is the moment a hypothesis is proven. It is a transformative verb that changes the status of information from 'private' or 'unknown' to 'shared' and 'understood.'

彼はついに自分の過去を明らかにする決心をした。
(He finally decided to reveal his past.)

Register and Tone
While B1 learners can use it, it leans toward the formal (Teineigo or Jitchigo). In casual settings, people might prefer 'hakkiri saseru' (to make clear). However, understanding Akiraka ni suru is vital for reading any Japanese media.

Using 明らかにする requires an understanding of Japanese transitive verb structures. The basic pattern is [Subject] ga [Object] o akiraka ni suru. The object is typically an abstract noun representing information, a mystery, a reason, or a plan. Unlike 'explain,' which focuses on the process, 'make clear' focuses on the outcome: the removal of ambiguity.

研究チームは、その病気の原因を明らかにした。
(The research team clarified the cause of that illness.)

One of the most common grammatical variations is the passive form: 明らかにされる (Akiraka ni sareru). This is ubiquitous in journalism. It shifts the focus onto the information being revealed, often when the source is a broad entity like 'the authorities' or when the discovery is the main news. For example, 'The truth was made clear' (Shinjitsu ga akiraka ni sareta).

Common Objects
Typical objects include: 理由 (riyuu - reason), 真相 (shinjou - truth), 正体 (shoutai - identity), 計画 (keikaku - plan), 事実 (jijitsu - fact), and 意図 (ito - intention).

When dealing with complex clauses, you can use the structure [Question Word] ka o akiraka ni suru. For instance, 'To make clear *why* he left' (Naze kare ga satta ka o akiraka ni suru). This is a vital pattern for academic and professional writing where you are defining the scope of an inquiry or investigation.

警察は、犯人がどのように侵入したかを明らかにする必要がある。
(The police need to clarify how the criminal broke in.)

In a debate or discussion, you might use it to demand clarity from an opponent: 'I want you to make your stance clear' (Anata no tachiba o akiraka ni shite hoshii). Here, the verb takes on a slightly more confrontational or assertive tone, demanding accountability. It is powerful because it implies that the person is currently being vague or deceptive.

市長は再出馬の意向をまだ明らかにしていません。
(The mayor has not yet made clear his intention to run for re-election.)

Finally, consider the potential for the causative-passive form in extremely formal literature or legal texts, though 'akiraka ni sareru' usually suffices. The verb's versatility across tenses (shita, shite iru, suru tsumori) allows it to describe past discoveries, ongoing investigations, and future disclosures with precision.

To truly master 明らかにする, one must look at the environments where it thrives. This is not a word you usually shout across a noisy izakaya while drinking with friends. Instead, it is the language of the 'public square.' If you turn on the 7 PM news on NHK, you are almost guaranteed to hear it within the first ten minutes. It is the standard way to report that a mystery has been solved or a statement has been issued.

The Newsroom
Journalists use this verb to maintain an objective distance. Instead of saying 'The company told us,' they say 'The company made clear (the fact that)...' This adds a layer of formal verification to the reporting.

最新の調査で、若者の投票率が低下していることが明らかにされた。
(In the latest survey, it was revealed that the voter turnout among young people is declining.)

In the corporate world, this verb appears in official documents and high-level presentations. When a CEO is clarifying the company's vision for the next five years, they will use Akiraka ni suru to signify that this is the official, definitive word of the organization. It is also used in troubleshooting: 'We must make clear the source of this software bug.'

Academic papers are another fertile ground for this verb. Researchers use it to state the objectives of their study. 'This paper aims to clarify the relationship between sleep and memory.' Here, it translates more as 'to elucidate' or 'to shed light on.' It sounds much more scholarly than 'shiraberu' (to investigate).

本論文では、古代日本の貿易ルートを明らかにしたい。
(In this paper, I want to clarify the trade routes of ancient Japan.)

Courtrooms and Law
Legal proceedings are essentially a long process of 'making things clear.' Judges and lawyers use this term to refer to the presentation of evidence and the establishment of facts beyond a reasonable doubt.

Even in fiction, specifically mystery novels (Honkaku Mystery), this verb is the climax. When the detective says 'Everything will be made clear tonight,' it signals the transition from the confusing 'Who-done-it' to the logical explanation of the crime. It represents the triumph of reason over chaos.

Despite its usefulness, English speakers often trip up when using 明らかにする because they treat it as a direct synonym for 'explain' (setsumei suru). This is the most common pitfall. While 'explain' is the *action* of telling someone something, 'make clear' is the *result* of ensuring it is no longer confusing. You can explain something poorly and fail to make it clear.

Mistake 1: Overuse in Casual Conversation
Saying 'Akiraka ni shite!' to a friend when you just didn't hear what they said is too heavy. It sounds like you are interrogating them. Use 'Mou ichido itte' or 'Hakkiri itte' instead.

Wrong: 昨日の晩ごはんを明らかにして。
(Clarify last night's dinner - sounds like a police investigation.)

Another mistake involves the particle usage. Some learners try to use 'ga' for the object because 'akiraka' is an adjective, but since 'ni suru' makes it a transitive verb phrase, you must use 'o' for the thing being clarified. 'The truth (o) make clear.'

Confusing Akiraka ni suru with Kaimei suru (to solve/elucidate) is common at higher levels. Kaimei is strictly for scientific or complex mysteries. You wouldn't kaimei your personal schedule, but you could akiraka ni suru your schedule to your colleagues.

❌ 彼は嘘を明らかにした。
✅ 彼は真実を明らかにした。
(He clarified the truth. You usually clarify the 'truth' or 'reason,' not the 'lie' itself, unless you are revealing that it was a lie.)

Finally, don't forget the 'ni'. Dropping the 'ni' makes the sentence ungrammatical. 'Akiraka suru' does not exist. The 'ni' is the glue that turns the state of 'clarity' into an action of 'making.' Mastery of this verb signals to Japanese speakers that you have moved beyond basic survival Japanese and are entering the realm of logical, structured discourse.

Japanese has a rich vocabulary for 'clarity' and 'explanation.' Choosing the right one depends on the context and the level of formality required. While 明らかにする is a great all-rounder for formal situations, other words might be more precise.

解明する (Kaimei suru)
Used for solving mysteries or scientific riddles. It implies a long, difficult process of discovery. You 'kaimei' the secrets of the universe or a difficult crime.
説明する (Setsumei suru)
The most common word for 'to explain.' It is neutral and focuses on the act of giving information. It doesn't necessarily imply that the truth was hidden before.
はっきりさせる (Hakkiri saseru)
The casual equivalent of Akiraka ni suru. It literally means 'to make things clear/distinct.' Use this with friends or in informal work settings.

There are also more specific terms like 究明する (Kyumei suru), which means to investigate thoroughly to find the truth, often used in political scandals. 提示する (Teiji suru) means to present or show something clearly, like evidence or a plan.

真相を究明する。
(To investigate and clarify the truth - very formal/journalistic.)

When comparing Akiraka ni suru to Setsumei suru, think of the difference between a detective revealing a clue (Akiraka) and a teacher explaining a math problem (Setsumei). One reveals something that was obscured; the other transfers knowledge.

In a business context, 明確にする (Meikaku ni suru) is a very close synonym. It means 'to make clear and definite.' While Akiraka ni suru is often about revealing a fact, Meikaku ni suru is about defining a goal or a definition so there is no room for misunderstanding. They are often interchangeable, but Meikaku sounds slightly more 'managerial.'

Errores comunes
  • Akiraka suru → Akiraka ni suru

    You cannot drop the 'ni' because 'Akiraka' is a Na-adjective/Noun that requires a particle to link to 'suru'.

  • Using it for 'explain' a person → Kare no koto o setsumei suru

    You clarify *facts*, you don't 'clarify a person' unless you mean revealing their secret identity.

  • Akiraka ni suru + ga → Object + o + Akiraka ni suru

    This is a transitive action, so the thing being clarified must take the 'o' particle.

  • Using in very casual talk → Hakkiri saseru

    Akiraka ni suru is quite formal. Using it with your best friend about what movie to see is too stiff.

  • Confusing with 'Akasu' → Akiraka ni suru

    While 'Akasu' also means to reveal, it's often used for secrets or spending the whole night (yo o akasu). 'Akiraka ni suru' is broader and more formal.

Consejos

The 'Ni' Particle

Always remember that 'Akiraka' is treated like a Na-adjective here. To change a state with 'suru', you need 'ni'. Think of it as 'Make it [into] clear'.

Objective vs Subjective

This verb is very objective. If you say 'Akiraka ni shita,' you are implying that the thing is now a fact, not just your opinion.

Newspaper Headlines

In headlines, you will often see '...を明らかに' with the verb 'suru' omitted. This is a standard shorthand in journalism.

Business Stance

If someone asks for your 'tachiba o akiraka ni shite,' they are asking you to take a side or state your position clearly.

Research Goals

When starting a paper, use 'Akiraka ni suru' to define what you are going to prove. It sounds professional and focused.

Avoid Interrogation

Don't use this too much with friends' secrets, as it can sound like you're a detective or a lawyer rather than a friend.

Pitch Accent

Focus on the flat pitch. If you rise too much on 'ra', it might sound like a different word or just non-native.

Kanji Choice

Always use 明らか. While other kanji like 彰 or 顕 exist for similar meanings, they are rare and 'Akiraka' is the standard.

Te-form usage

Use 'Akiraka ni shite...' when asking someone for clarification in a polite but firm way.

Transitive/Intransitive

Regularly compare 'ni suru' (I make clear) with 'ni naru' (It becomes clear) to master the causative nature of Japanese verbs.

Memorízalo

Mnemotecnia

Think of 'Akira' (a famous name/movie) and 'KA' (camera). A camera lens makes things clear. Akira makes the camera clear: Akiraka ni suru.

Asociación visual

Imagine a dark room where someone flips a switch. The light (Akiraka) makes everything visible (ni suru).

Word Web

Sun/Moon Light Truth Discovery News Explanation Mystery Clear

Desafío

Try to find three news headlines today that use '明らか' and see if they are transitive (ni suru) or intransitive (ni naru).

Origen de la palabra

Derived from the ancient Japanese adjective 'akiraka,' which has roots in the Old Japanese word 'akira.' It is related to the word 'aka' (red/bright) and 'akari' (light).

Significado original: Originally referred to the physical brightness of the sun or moon, which made objects visible and distinct from the surrounding darkness.

Japonic (Yamato Kotoba).

Contexto cultural

Be careful when asking someone to 'Akiraka ni suru' their personal life; it can sound like an interrogation.

English speakers often use 'clarify' in business, but 'Akiraka ni suru' is even more common in Japanese news than 'clarify' is in English news.
