Erklärung 貢献 in your Level:
At the A1 level, you don't need to use '貢献' (kōken) yourself yet. Instead, focus on the basic word for 'help,' which is 'tasukeru' or 'tetsudau.' However, if you see the kanji 貢献, just remember it means 'a big help' or 'giving something good to others.' You might see it in simple signs about helping the community. At this stage, think of it as 'Special Helping.' It is a formal word that adults use when they do something important for a group or a city. You won't hear it in a playground, but you might hear it on the news or in a big company building. Just knowing it means 'helping in a big way' is enough for now.

At the A2 level, you might start seeing '貢献' in simple news articles or school textbooks. It is a 'suru-verb,' so it becomes '貢献する' (kōken suru). You can use it to talk about how a player helped a sports team win, or how a famous person helped people after a disaster. Remember that it is a 'big' word. Instead of saying 'I helped my mom' (which uses 'tetsudau'), you use 'kōken' for things like 'The player helped the team win.' It always uses the particle 'ni' for the thing you are helping. For example, 'Team ni kōken suru' (Contribute to the team). It is a step up from basic verbs and makes you sound more grown-up and respectful when talking about important actions.

At the B1 level, you should be able to recognize '貢献' in various contexts like business, science, and social issues. You are starting to understand that Japanese has different 'registers' (levels of formality). 'Kōken' is a formal word. You might use it in a job interview or a speech. For example, if you are a volunteer, you can say 'I want to contribute to society' (社会に貢献したいです - Shakai ni kōken shitai desu). You should also notice how it is often used with 'ōkiku' (greatly) to say 'ōkiku kōken suru.' This level is about moving beyond personal help and talking about contributing to projects, goals, and communities. You are learning that your actions have an impact on the world around you, and 'kōken' is the word to describe that impact.

At the B2 level, which is the level for this word, you should use '貢献' (kōken) accurately in professional and academic settings. You understand the nuance that it implies a positive, measurable impact. You can distinguish it from 'jinryoku' (effort) and 'kiyo' (technical contribution). You are comfortable using it in the passive voice (貢献が認められる - contribution is recognized) or as a compound noun like 'shakai kōken' (social contribution). You know that it requires the particle 'ni' and is often modified by formal adverbs like 'tadai ni' (immensely). In business discussions, you can use it to describe your value to a company or how a product benefits the market. This word is a key part of your 'formal' Japanese toolkit.
At the C1 level, you use '貢献' with high precision and variety. You are aware of its collocations, such as 'kōkendo' (degree of contribution) or 'kōkensha' (contributor). You can use it in complex sentence structures to discuss abstract concepts like 'civilization,' 'humanity,' or 'economic stability.' You understand the subtle differences between 'kōken' and its synonyms like 'kiyo' in scientific literature or 'hōshi' in philanthropic contexts. You can also use it rhetorically in debates or formal essays to argue the value of certain actions or policies. Your usage is indistinguishable from a native speaker in professional environments, and you can explain the historical or kanji-based nuances of the word to others.

At the C2 level, '貢献' is a word you use with complete mastery in any context, from high-level diplomatic speeches to intricate legal or academic documents. You understand the poetic and historical weight of the kanji (貢 - tribute, 献 - offering) and how this history influences its modern formal usage. You can use it in sophisticated wordplay or highly nuanced critiques. You are also capable of recognizing and correcting very subtle misuses of the word by others. For you, '貢献' is not just a vocabulary item but a concept that you can weave into complex discussions about ethics, global responsibility, and the evolution of society. You use it to articulate the highest forms of human achievement and altruism.

貢献 in 30 Sekunden

  • 貢献 (kōken) means 'contribution' and is used for formal, positive impacts on groups or society.
  • It is a 'suru-verb' (貢献する) and usually takes the particle 'ni' for the target.
  • Commonly used in business, science, and social contexts to describe meaningful help.
  • Avoid using it for small personal favors; use 'tasukeru' or 'tetsudau' instead.

The Japanese word 貢献 (こうけん - kōken) is a sophisticated noun that translates primarily to 'contribution.' While it can be used in everyday conversation, it carries a weight of formality and significance, often associated with making a meaningful impact on a larger scale, such as for society, a company, science, or a specific cause. Unlike the simple verb 'help' (助ける - tasukeru), 貢献 implies a structured or long-term effort that leads to progress or success. It is a 'suru-verb,' meaning you can add 'suru' to make it 'kōken suru' (to contribute). In the context of Japanese culture, which values group harmony and societal well-being, this word is frequently encountered in corporate mission statements, academic papers, and speeches acknowledging the hard work of individuals or groups.

Societal Contribution
This refers to activities that benefit the public good, often termed 社会貢献 (shakai kōken). It covers everything from volunteering to corporate philanthropy.
Academic and Scientific Contribution
Used when a researcher's findings advance a field of study. You might hear: '科学の発展に貢献する' (Contributing to the development of science).
Corporate and Business Usage
Employees are often evaluated on their '貢献度' (kōkendo - level of contribution) to the company's profits or project goals.

ボランティア活動を通じて、地域社会に貢献したいと考えています。 (I want to contribute to the local community through volunteer activities.)

彼の新しい理論は、物理学の世界に多大な貢献をもたらした。 (His new theory brought a great contribution to the world of physics.)

企業は利益を追求するだけでなく、環境保護への貢献も求められている。 (Companies are expected not only to pursue profit but also to contribute to environmental protection.)

チームの勝利に貢献できて、本当に嬉しいです。 (I am truly happy that I could contribute to the team's victory.)

この技術革新は、人類の未来に大きく貢献するだろう。 (This technological innovation will likely contribute greatly to the future of humanity.)

In summary, 貢献 is a powerful word that signals professionalism, altruism, and measurable impact. Whether you are writing a resume, a business proposal, or an academic essay, mastering this word allows you to articulate value and purpose in a way that resonates deeply with Japanese linguistic expectations of responsibility and social connectivity.

Using 貢献 (kōken) correctly involves understanding its grammatical role as a 'suru-verb' and its relationship with specific particles. The most common structure is [Recipient/Field] に 貢献する. The recipient can be an organization, a field of study, a community, or even a specific project. It is important to note that the contribution is usually positive. You wouldn't use 貢献 to describe contributing to a problem; for negative impacts, words like 'gen'in' (cause) are preferred.

The 'Ni' Particle
The particle 'ni' (に) marks the direction of the contribution. Example: 'Sekai heiwa ni kōken suru' (Contribute to world peace).
Degree Modifiers
Commonly paired with adverbs like '大きく' (ōkiku - greatly) or '多大に' (tadai ni - immensely) to emphasize the scale of the help.
Noun Forms
As a standalone noun, it can be the subject or object. Example: 'Kōken ga mitomerareta' (The contribution was recognized).

彼女の功績は、医学の進歩に大きく貢献しました。 (Her achievements contributed greatly to the progress of medicine.)

私たちは、持続可能な社会の実現に貢献することを目指しています。 (We aim to contribute to the realization of a sustainable society.)

この寄付金は、教育環境の改善に貢献するために使われます。 (This donation will be used to contribute to the improvement of the educational environment.)

彼は長年、地域の防犯活動に貢献してきた。 (He has contributed to local crime prevention activities for many years.)

新しいプロジェクトでのあなたの貢献を期待しています。 (I am looking forward to your contribution in the new project.)

When constructing sentences, remember that 貢献 usually implies a selfless or professional drive. It is the language of 'giving back.' Whether you are describing how a technology helps the environment or how an athlete helps their team, 貢献 provides the necessary gravitas to show that the impact is recognized and valued by others.

You will encounter 貢献 (kōken) in several key domains of Japanese life. It is not a word you would typically use while chatting with friends about a video game, but it is ubiquitous in professional and civic life. Understanding these contexts will help you recognize the 'vibe' of the word—which is one of respectability and high-level achievement.

News and Media
Journalists use 'kōken' to describe the impact of policy changes, scientific breakthroughs, or the actions of philanthropists. 'Economic contribution' (経済への貢献) is a frequent headline.
Business Environments
During performance reviews, a manager might say, 'Kotoshi no kōken wa subarashikatta' (Your contribution this year was wonderful). It is also used in Corporate Social Responsibility (CSR) reports.
Sports Commentary
When a player makes a game-winning play or consistently supports the team, commentators will mention their 'kōken' to the victory.

彼はノーベル賞を受賞し、人類の科学知識に多大な貢献をした。 (He won the Nobel Prize and made a great contribution to human scientific knowledge.)

当社の製品は、省エネ社会の実現に貢献しています。 (Our products contribute to the realization of an energy-saving society.)

地域に貢献する企業として、お祭りを支援しています。 (As a company that contributes to the community, we are supporting the festival.)

その選手は攻守にわたってチームに貢献した。 (The player contributed to the team both offensively and defensively.)

ボランティア団体は、震災復興に大きく貢献しました。 (The volunteer organization contributed greatly to the earthquake recovery.)

Basically, if the context involves public recognition, professional evaluation, or high-level goals, '貢献' is the word of choice. It elevates the conversation from 'doing a task' to 'making a difference.'

While 貢献 (kōken) is a versatile word, learners often make a few specific errors. The most common mistakes involve particle usage, confusion with similar-looking words, and using it in inappropriate registers or contexts. Because it is a formal word, using it for very minor, personal things can sound a bit 'stiff' or even sarcastic if not careful.

Mistake: Using 'o' (を) instead of 'ni' (に)
Learners often think 'contribute [something]' and try to use を. While you can say 'kōken o suru' (to do a contribution), the target of the contribution must be marked with に. Incorrect: 'Sekai o kōken suru'. Correct: 'Sekai ni kōken suru'.
Mistake: Confusing with 'Kifu' (寄付)
'Kifu' specifically means donating money or goods. 'Kōken' is broader and includes effort, time, and influence. You can contribute (kōken) through a donation (kifu), but they are not interchangeable.
Mistake: Using it for Negative Results
'Kōken' has a positive nuance. Using it to say someone 'contributed' to a disaster sounds like you are praising the disaster. Use 'gen'in to naru' (become the cause) or 'akueikyō o ataeru' (give a bad influence) instead.

❌ 彼は失敗に貢献した。 (Incorrect: He contributed to the failure.)

✅ 彼は成功に貢献した。 (Correct: He contributed to the success.)

❌ 社会を貢献する。 (Incorrect: Contribute society.)

✅ 社会に貢献する。 (Correct: Contribute to society.)

❌ 友達にペンを貸して貢献した。 (Too stiff: Contributed by lending a pen.)

By keeping these pitfalls in mind—especially the positive nuance and the 'ni' particle—you will sound much more natural and professional when using this important term.

Japanese has several words that overlap with 貢献 (kōken). Choosing the right one depends on the context, the level of formality, and whether you are focusing on the effort, the donation, or the result. Here is a breakdown of the most common alternatives.

寄与 (きよ - kiyo)
Very similar to 'kōken,' but even more academic or technical. It is used for cause-and-effect relationships where one thing 'contributes' to a result. Example: 'This factor contributed (kiyo) to the price increase.'
尽力 (じんりょく - jinryoku)
This focuses on the 'effort' or 'devotion' someone puts in. While 'kōken' looks at the outcome, 'jinryoku' looks at the hard work. Example: 'Thank you for your efforts (jinryoku) in organizing this event.'
奉仕 (ほうし - hōshi)
This means 'service' or 'ministry,' often with a sense of selfless sacrifice or religious duty. It is commonly used in 'volunteer service' (hōshi katsudō).

その新薬は、病気の治療に大きく寄与した。 (The new drug contributed significantly to the treatment of the disease.)

プロジェクトの成功のために尽力します。 (I will exert my best efforts for the success of the project.)

彼は生涯を社会奉仕に捧げた。 (He dedicated his life to social service.)

皆様のご協力をお願いします。 (We ask for everyone's cooperation.)

彼はチームの勝利に一役買った。 (He played a part in the team's victory.)

Understanding these nuances allows you to be more precise. While 'kōken' is the safest and most common choice for 'contribution,' knowing when to switch to 'kiyo' or 'jinryoku' will make your Japanese sound much more advanced and nuanced.
