意見する

iken suru
At the A1 level, you don't need to use '意見する' (iken suru) yourself yet. Instead, you should focus on the noun '意見' (iken), which means 'opinion.' You might learn simple sentences like '私の意見です' (It is my opinion). The verb 'iken suru' is a bit too complex because it involves social hierarchy and formal settings. At this stage, just remember that 'iken' is a word for 'what you think.' If you see 'iken suru,' just think of it as 'saying an opinion.' You will mostly use '思います' (omoimasu - I think) to express your own views.
At the A2 level, you start to see 'suru-verbs' more often. '意見する' is one of them. You might encounter it in simple reading passages about school or work. You should understand that it means 'to give an opinion.' You might see it in a sentence like '会議で意見しました' (I gave an opinion at the meeting). At this level, you are learning that Japanese has different words for 'speaking' depending on the situation. 'Iken suru' is a bit more formal than 'hanasu' (talk) or 'iu' (say). You should practice the basic conjugation: iken suru, iken shimasu, iken shita.
B1 is the level where you should start using '意見する' actively. This is the 'Threshold' level where you can handle most everyday situations in Japan. You should understand that 'iken suru' often implies giving advice or even disagreeing with someone. For example, '親に意見する' (to voice an opinion to one's parents). You are learning to navigate social relationships, and knowing when to use 'iken suru' versus 'iken wo iu' is important. Use 'iken suru' when you want to sound more professional or when you are describing a situation where someone is taking a stand.
At the B2 level, you should be comfortable with the nuances of '意見する.' You understand that it can mean 'to remonstrate' or 'to object.' You can use it in complex sentences with particles like 'に対して' (against) or 'について' (about). You also recognize it in news reports and business emails. You understand that 'iken suru' is a way to show agency. For instance, in a discussion about social issues, you might say '政府の政策に意見する権利がある' (We have the right to voice our opinions on government policy). You are also aware of the humble forms like '意見させていただきます.'
At the C1 level, you use '意見する' with precision. You understand its historical weight and its place among other verbs like '提言する' (propose) or '異議を唱える' (object). You can use 'iken suru' to describe subtle power dynamics in literature or high-level business negotiations. You are aware that in some contexts, 'iken suru' can be seen as a bold act of 'kotoage' (speaking out), which might be viewed either positively (as integrity) or negatively (as disrupting harmony) depending on the speaker's skill and the listener's status. You can use it fluently in academic writing or formal debates.
At the C2 level, '意見する' is just one tool in your vast linguistic arsenal. You can manipulate its tone through advanced grammar and register shifts. You might use it in a philosophical discussion about the nature of public discourse or in a legal analysis of 'iken-sho' (written opinions). You understand the deep cultural implications of 'iken suru' in a society that values 'kuuki wo yomu' (reading the air). You can use the word to critique social structures or to provide highly nuanced feedback in a professional setting, perfectly balancing directness with the necessary Japanese etiquette.

意見する en 30 segundos

  • A formal verb meaning to state an opinion.
  • Often implies giving advice or objecting to something.
  • Commonly used with the particle 'ni' for the recipient.
  • Essential for business and formal Japanese communication.

The verb 意見する (iken suru) is a fundamental yet nuanced Japanese expression that translates to 'to state an opinion' or 'to express one's view.' At its core, it combines the noun 意見 (opinion/view) with the light verb する (to do). However, unlike the more neutral 意見を言う (to say an opinion), iken suru often carries a weight of intentionality and, in many contexts, a sense of offering advice, criticism, or a counter-argument to someone, particularly a superior or someone in a position of authority.

Core Meaning
The act of actively putting forward a perspective, often to influence a decision or correct a course of action.
Grammatical Function
A Suru-verb (Group 3) that can take the particle 'ni' (to someone) or 'wo' (the opinion itself, though 'ni' is more common for the target).
Social Weight
In Japanese culture, 'iken suru' can imply a level of bravery or friction, as it often involves speaking up against the status quo.

「上司の決定に意見するのは勇気がいる。」(It takes courage to voice an opinion/objection to a boss's decision.)

When you use this verb, you aren't just chatting; you are positioning yourself. It suggests a formal or semi-formal setting where your input is intended to be taken seriously. In a business meeting, if you 'iken suru,' you are contributing to the discourse with the intent of shaping the outcome. It is less about 'sharing feelings' and more about 'stating a position.'

「彼は会議で積極的に意見した。」(He actively stated his views during the meeting.)

Historically, the term 意見 (iken) has roots in Buddhist philosophy and legal contexts, referring to the discernment of truth or the presentation of a formal case. In modern Japanese, while it has lost its religious overtones, it retains a sense of 'formal presentation.' It is a 'harder' word than 'omou' (to think) or 'iu' (to say). It implies that the thought has been processed and is now being presented as a structured viewpoint.

Usage in Debate
Used when one person challenges another's logic or provides a different perspective.
Usage in Mentorship
When an elder or expert gives 'iken' to a junior, it often functions as 'admonishment' or 'guidance.'

「親に意見するなんて、君も成長したね。」(Stating your own opinion to your parents... you've really grown up, haven't you?)

Using 意見する correctly requires understanding its grammatical structure and the social hierarchy of the conversation. As a Suru-verb, it follows standard conjugation patterns but is unique in how it interacts with particles. The most common pattern is [Person] に 意見する, meaning 'to express an opinion to [Person].' This often implies that the opinion is a form of advice or even a mild rebuke.

  • Polite Form: 意見します (Iken shimasu)
  • Te-form (Connecting): 意見して (Iken shite)
  • Potential Form: 意見できる (Can express an opinion)
  • Passive Form: 意見される (To have someone express an opinion/objection to you)

In a professional setting, you might hear the phrase 「意見させていただきます」 (I will take the liberty of expressing my opinion). This uses the humble causative form to soften the potential impact of 'iken suru,' which can otherwise sound quite direct or even confrontational. Because 'iken suru' involves putting your thoughts forward, it is often paired with adverbs like 堂々と (boldly), はっきりと (clearly), or 遠慮なく (without reservation).

「若手社員が社長に意見するのは珍しい。」(It is rare for a young employee to voice an opinion to the president.)

Another important aspect is the difference between iken suru and iken wo iu. While iken wo iu is simply 'to say an opinion,' iken suru is the act of 'opining' or 'remonstrating.' If a teacher 'iken suru' to a student, they are likely correcting the student's behavior or thinking. If a student 'iken suru' to a teacher, they are likely challenging the teacher's statement. This 'active' quality makes it a powerful verb in your vocabulary.

Correct Particle Usage

Use に for the recipient of the opinion.
Use について for the topic of the opinion.

Common Collocation

真っ向から意見する
(To voice an opinion/objection head-on.)

When writing, iken suru is frequently found in editorials, business reports, and literature where a character is standing up for their beliefs. It is less common in casual daily conversation (where 'omou' or 'iu' are preferred) unless the situation is serious. For example, if you are disagreeing with a friend about where to eat, you wouldn't say 'iken suru.' But if you are disagreeing with a friend about their life choices, 'iken suru' might be appropriate.

You will encounter 意見する in various structured environments. Its presence usually signals that the 'wa' (harmony) is being tested or that a formal exchange of ideas is taking place. Here are the primary locations where this verb is heard:

1. The Corporate Boardroom

In Japanese business culture, the 'Ringi' system (consensus-based decision making) is common. However, during the 'Meigi' or formal discussion phase, participants are expected to iken suru. You'll hear it in phrases like 「どなたか意見する方はいますか？」 (Is there anyone who wishes to state an opinion?).

2. News and Political Debates

On talk shows like 'Sunday Project' or during Diet (parliament) sessions, commentators and politicians will iken suru regarding government policies. It is used to describe the act of formal opposition or the presentation of a policy alternative. The media often reports: 「野党は政府の案に強く意見した。」 (The opposition party strongly voiced their views/objections to the government's proposal.)

3. Legal and Academic Settings

In a court of law, an expert witness might iken suru (provide an expert opinion). Similarly, in academic peer reviews, scholars iken suru on each other's research papers. Here, the word takes on a highly professional and objective tone.

「専門家として、この計画に意見させていただきたい。」(As an expert, I would like to offer my opinion on this plan.)

4. Family and Social Hierarchies

In anime or dramas, you often see a scene where a younger character finally 'iken suru' to a strict patriarch or a bullying senpai. This is a trope representing character growth and the assertion of self. It’s the moment they stop being passive and start being active participants in their own lives.

While 意見する seems straightforward, learners often stumble over its specific nuances and grammatical constraints. Avoiding these common pitfalls will make your Japanese sound much more natural.

1. Confusing with '意見を言う' (Iken wo iu)

This is the most frequent error. Iken wo iu is a general phrase for saying what you think. Iken suru is more formal and often implies a challenge or advice. If you are just sharing a thought about a movie, use iken wo iu. If you are telling your friend they are making a mistake, iken suru is better.

2. Misusing the Particle 'NI'

Learners often try to use 'TO' (with) like in English 'I shared an opinion with him.' In Japanese, it is almost always [Person] に 意見する. Using 'TO' changes the meaning to 'having an opinion together,' which is not how the verb is used.

3. Overusing it in Casual Situations

Saying 「君に意見するよ」 (I'm going to give you my opinion) to a friend during a casual lunch can sound overly dramatic or even condescending. It sounds like you are about to deliver a formal lecture. In casual settings, stick to 「ちょっと言いたいことがあるんだけど」 (There's something I want to say) or 「私はこう思う」 (I think this).

Don't Say:

「美味しいレストランについて意見します。」 (I will opine about a delicious restaurant.)

Instead Say:

「おすすめのレストランを教えます。」 (I'll tell you my recommended restaurants.)

4. Forgetting the 'Remonstrance' Nuance

In many contexts, iken suru implies that you are pointing out something wrong. If you use it when you are actually agreeing with someone, it can create confusion. If you agree, use 賛成する (sansei suru - to agree) or 同意する (doui suru - to concur).

Japanese has a rich vocabulary for expressing thoughts. Understanding the subtle differences between 意見する and its synonyms will help you choose the right word for the right situation.

主張する (Shuchou suru)
To insist or assert. This is stronger than iken suru. It implies you are firmly standing by your point and perhaps trying to convince others that you are right. It is common in debates and legal contexts.
発言する (Hatsugen suru)
To make a remark or to speak up. This is a very neutral term used in meetings to describe the act of speaking. It doesn't necessarily mean you are giving an opinion; you could just be asking a question.
提言する (Teigen suru)
To propose or suggest. This is a more constructive and formal version of iken suru. It is often used when an expert or a committee provides a formal recommendation to a body of government or a company.
忠告する (Chuukoku suru)
To advise or warn. This overlaps with the 'admonishing' side of iken suru but is much more direct about the intent to give advice for the person's own good.
