Explicación 解決する in your Level:

At the A1 level, you can think of 'kaiketsu suru' as 'to solve' or 'to fix' a simple problem. While the word itself is a bit advanced for absolute beginners, you might hear it in very simple contexts like 'Mondai o kaiketsu shimasu' (I will solve the problem). It is similar to saying 'I found the answer'. You use it when you finish a task or find a way to make something work. It's a useful word to know when you want to sound a bit more formal than just saying 'I did it'. Imagine you are playing a game and you find the key to a door—that is a small 'kaiketsu'.

At the A2 level, you start using 'kaiketsu suru' for everyday troubles. For example, if you have a problem with your roommate about the cleaning, and you talk and decide on a rule, you can say 'Mondai ga kaiketsu shimashita' (The problem was resolved). It's a step up from 'naosu' (to fix) because it's about situations, not just broken things. You will see this word in simple news stories or in textbooks when talking about 'how to solve' (kaiketsu no shikata) basic social issues. It helps you describe moving from a difficult situation to a good one.

At the B1 level, you should be able to use '解決する' comfortably in work and school settings. This is where you distinguish between 'solving a problem' (kaiketsu) and 'answering a question' (kaitō). You can use it to discuss social issues, like 'how to solve environmental problems' (kankyō mondai o kaiketsu suru). You also begin to use the noun form 'kaiketsu-saku' (solution) to offer suggestions. You understand that this word implies a logical process and a definitive end to a conflict or difficulty. It is a key word for participating in discussions and expressing your opinion on how to improve things.

At the B2 level, you use '解決する' to describe complex, multi-faceted issues. You can discuss the 'fundamental resolution' (kompon-teki na kaiketsu) of a problem versus a 'temporary fix' (ichiji-teki na taishō). You are familiar with its use in legal, political, and technical contexts. You can use the passive voice 'kaiketsu sareru' to talk about how issues are handled by authorities or society. You also start to recognize the nuance between 'kaiketsu' and its synonyms like 'kaishō' (dissolution) or 'shori' (processing), and you can choose the most appropriate word based on the context of the discussion.

At the C1 level, '解決する' is used with high precision in professional and academic discourse. You can analyze the 'process of resolution' (kaiketsu no katei) and discuss 'dispute resolution' (funsō kaiketsu) in international relations or law. You use it to describe the resolution of cognitive dissonance or complex scientific paradoxes. You are comfortable with formal collocations like 'kaiketsu o miru' (to see a resolution) or 'kaiketsu ni itaru' (to reach a resolution). Your usage reflects an understanding of the systemic implications of a 'kaiketsu', acknowledging that some resolutions are structural while others are merely symptomatic.

At the C2 level, you master the subtle rhetorical uses of '解決する'. You can use it ironically or critically to discuss 'pseudo-resolutions' in political rhetoric. You understand its philosophical weight in existential or dialectical discussions—where a 'kaiketsu' might represent the synthesis of opposing forces. You can navigate highly technical legal documents where 'kaiketsu' has specific statutory meanings. Your command of the word allows you to discuss the 'unsolvability' (kaiketsu funō) of certain human conditions or mathematical theorems with the nuance of a native speaker, using it to frame complex intellectual inquiries.

解決する en 30 segundos

解決する (kaiketsu suru) means to solve or resolve abstract problems, disputes, or mysteries definitively.
It is a formal Suru-verb used in business, news, and academic contexts, distinct from physical repairs.
The word implies moving from a state of confusion or conflict to one of clarity and closure.
Commonly paired with 'mondai' (problem) and 'funsō' (dispute), it can be used transitively or intransitively.

The Japanese verb 解決する (kaiketsu suru) is a cornerstone of professional and daily communication, representing the act of resolving a problem, settling a dispute, or finding a definitive answer to a complex situation. It combines two powerful kanji: 解 (kai), meaning to untie, unravel, or understand, and 決 (ketsu), meaning to decide or determine. Together, they imply not just a temporary fix, but a conclusive resolution where the 'knot' of the problem is untied and a 'decision' is reached. In a CEFR B1 context, this word is essential for discussing challenges at work, school, or in personal relationships. It transcends simple 'fixing' (naosu) by implying a logical or systematic conclusion to an issue that was previously ambiguous or problematic.

Core Concept: The transition from a state of conflict or uncertainty to a state of clarity and closure.
Grammatical Function: A Suru-verb (Noun + suru) that functions as a transitive verb taking the particle 'o' for the object being solved.
Nuance: It carries a formal and objective tone, often used in news, business reports, and serious discussions.

話し合いによって、長年の紛争がようやく解決した。

Through discussion, the long-standing dispute was finally resolved.

この数学の難問を解決するには、新しい視点が必要です。

トラブルが解決して、ほっとしました。

政府は経済問題を解決するための新しい政策を発表した。

その事件は、警察の懸命な捜査によって解決された。

Furthermore, 解決する can be used both as an intransitive verb (something resolves) and a transitive verb (someone resolves something). This versatility makes it a high-frequency word in both JLPT N3 and N2 levels. When a problem 'solves itself' or reaches a state of resolution, we say 'mondai ga kaiketsu suru'. When an active agent solves it, we say 'mondai o kaiketsu suru'. Understanding this distinction is key to natural Japanese. In academic writing, it is frequently paired with words like 'ito' (intent) or 'shuhō' (method) to describe the process of scientific discovery or social reform.

Using 解決する correctly requires understanding its collocations and the specific types of 'problems' it addresses. It is most commonly paired with nouns like 問題 (mondai - problem), 紛争 (funsō - dispute), 悩み (nayami - worry/trouble), and 事件 (jiken - incident). Unlike the English 'fix,' which can apply to physical objects like cars, 解決する is almost exclusively for abstract concepts, logical puzzles, or social situations. If your car is broken, you use 'shūri suru' (repair), not 'kaiketsu suru'. However, if the *situation* caused by the car breaking down is causing a logistical nightmare, you might 'kaiketsu' that situation.

Transitive Usage: [Person] ga [Problem] o kaiketsu suru. (I solve the problem.)
Intransitive Usage: [Problem] ga kaiketsu suru. (The problem is resolved.)
Formal Contexts: Often used in the passive form 'kaiketsu sareru' in news reports to emphasize the resolution rather than the actor.

AIを使って、複雑な物流の課題を解決する。

時間が経てば、この問題は自然に解決するでしょう。

彼は持ち前の明るさで、チームの人間関係を解決した。

In professional settings, you will often hear 'kaiketsu-saku' (solution/measure). This is the noun form combined with 'saku' (plan/measure). When presenting at a meeting, you might say, 'Kono mondai ni taisuru kaiketsu-saku o teian shimasu' (I propose a solution to this problem). This sounds much more professional than simply saying 'how to fix it'. The verb can also be used in the potential form 'kaiketsu dekiru' (can solve) or the negative 'kaiketsu dekinai' (cannot solve), which is a common way to express frustration with systemic issues or deep-seated personal conflicts. Remember that 解決 is a kango (Sino-Japanese word), so it naturally feels more formal than wago (native Japanese words) like 'tokun' (to untie/solve).

You will encounter 解決する in a wide variety of environments, ranging from the evening news to the detective novels of Keigo Higashino. In news broadcasts, it is the standard term for reporting that a crime has been solved or a diplomatic standoff has ended. In business, it's the language of the 'problem-solver'—a highly valued trait in corporate Japan. In educational settings, teachers use it when discussing math problems or historical conflicts. Even in daily life, friends might use it when talking about settling a misunderstanding or a difficult family situation.

「犯人が逮捕され、事件はスピード解決に向かいました。」

News Anchor: 'The suspect was arrested, and the case moved toward a speedy resolution.'

「君の力で、このプロジェクトの遅れを解決してほしい。」

Manager: 'I want you to solve the delay in this project with your skills.'

In literature and media, the word often appears in the context of 'mystery solving' (nazo-toki). While 'nazo-toki' is the common term for the act of solving a riddle, the formal conclusion of the plot is often described as 'kaiketsu'. In the legal world, 'saiban-gai kaiketsu' (out-of-court settlement) is a technical term used frequently in legal dramas and news. In psychological contexts, 'mondai kaiketsu nōryoku' (problem-solving ability) is a common phrase used in self-help books and career counseling. Whether it's a high-stakes international treaty or a simple disagreement between roommates, 解決する provides the linguistic framework for reaching a conclusion.

The most frequent mistake learners make with 解決する is using it for physical repairs. In English, 'solve' and 'fix' are sometimes interchangeable, but in Japanese, they are strictly separated. You cannot 'kaiketsu' a broken window or a leaking faucet; for those, you must use 修理する (shūri suru) or 直す (naosu). Another common error is confusing it with 解答する (kaitō suru), which specifically means to 'answer' a question on a test. While solving a math problem is 'kaiketsu suru', providing the specific answer to question number five is 'kaitō suru'.

Mistake 1: Physical Objects: Incorrect: パソコンを解決する (Solve the PC). Correct: パソコンを修理する (Repair the PC).
Mistake 2: Test Answers: Incorrect: テストを解決する (Solve the test). Correct: テストを解く (Solve/Work through the test).

× 壊れたドアを解決する。
○ 壊れたドアを直す。

Additionally, learners sometimes struggle with the particle choice. While 'o' is used when you are the agent of change, 'ga' is used when the focus is on the state of the problem. For example, 'Mondai ga kaiketsu shimashita' (The problem has been resolved) is often more natural than 'Mondai o kaiketsu shimashita' unless you want to emphasize that *you* were the one who did it. Finally, avoid using 解決する for 'solving' a mystery in a casual way if you just mean 'figuring it out'—in those cases, 'wakaru' or 'nazo ga tokeru' might be more appropriate for everyday conversation.

Japanese has several words that overlap with 解決する, and choosing the right one depends on the nature of the 'solution'. The most common synonyms are 処理する (shori suru), 解消する (kaishō suru), and 収拾する (shūshū suru). 処理する refers to 'processing' or 'handling' a task or data—it's more about management than finding a final answer. 解消する is used for 'dissolving' something, like stress, a contract, or a misunderstanding, where the goal is to make the problem disappear entirely rather than 'solving' its logic.

解決 vs 処理: 解決 is finding the answer; 処理 is handling the paperwork or the routine task.
解決 vs 解消: 解決 is for problems with answers; 解消 is for feelings or states that need to be removed.
解決 vs 収拾: 収拾 is 'bringing under control', usually used for chaotic situations or riots.

ストレスを解消するために、ジョギングを始めた。

I started jogging to relieve (dissolve) stress.

Another related word is 決着する (ketchaku suru), which means 'to come to a conclusion' or 'to settle a match'. This is often used in sports or long-standing battles where there is a clear winner and loser. While 解決 implies a positive or logical resolution, 決着 just implies that it's over. For example, 'Shōbu no ketchaku ga tsuita' (The match was settled). Understanding these nuances allows you to describe the 'end' of a situation with much greater precision in Japanese.

Consejos

Pair with 'Mondai'

The most natural pairing is 'Mondai o kaiketsu suru'. If you are unsure, this is always a safe and correct combination to use in any setting.

Passive Voice

In news reports, you will often hear 'kaiketsu saremashita'. This focuses on the fact that the problem is over, rather than who did it. It sounds very objective.

Learn 'Mikaiketsu'

If you like crime dramas, 'Mikaiketsu' (unsolved) is a must-know word. It's often used for cold cases or mysterious disappearances.

Harmony First

Remember that in Japan, a 'kaiketsu' that makes everyone feel respected is often better than a 'kaiketsu' that is just logically perfect but hurts feelings.

Business Pro

When you find a bug in a system, tell your boss 'Kaiketsu-saku o sagashite imasu' (I am looking for a solution). It shows you are proactive and professional.

Kanji Practice

The kanji 'Kai' (解) is also in 'wakaru' (to understand). Thinking of 'kaiketsu' as 'making it understandable and decided' helps you remember the meaning.

Context Clues

If you hear 'kaiketsu' in a movie, look at the characters' faces. If they look relieved, the problem is gone. If they look tense, they might be talking about a 'mikaiketsu' issue.

Untie the Knot

The first kanji '解' looks like a horn and a knife. Imagine using a knife to carefully untie a difficult knot. That is the essence of 'kaiketsu'.

JLPT Tip

In the JLPT, 'kaiketsu' is often the correct answer when the context involves a 'trouble' (toraburu) or 'dispute' (arasoi).

Not for Tests

Don't say 'kaiketsu' for a multiple-choice question on a test. Use 'toku' (to solve) or 'kotaeru' (to answer). 'Kaiketsu' is for bigger issues.

Memorízalo

Origen de la palabra

Sino-Japanese (Kango) origin, combining the concepts of unraveling a knot and making a firm decision.

Contexto cultural

High preference for settlements over long court battles.

Harmony is often prioritized over a 'perfect' logical solution.

Preguntas frecuentes

10 preguntas

No, for a broken phone, you should use 修理する (shūri suru) or 直す (naosu). 解決する is for abstract problems like a software bug or a billing dispute. If you 'kaiketsu' a phone problem, it implies you solved a contract issue, not the screen.

解決 implies a logical or positive resolution where the problem is 'solved'. 決着 (ketchaku) simply means a conclusion or settlement, often used in competitions or fights where there is a winner and a loser. 解決 is more about the 'answer', while 決着 is about the 'end'.

It can be both. 'Mondai o kaiketsu suru' (transitive) means someone solves the problem. 'Mondai ga kaiketsu suru' (intransitive) means the problem reaches a resolution. Both are very common in Japanese.

Yes, 'sūgaku no mondai o kaiketsu suru' is correct and formal. However, in a classroom setting, students often use '解く' (toku) which means 'to solve/work through' the problem.

You use the prefix '未' (mi-) to make '未解決' (mikaiketsu). This is commonly used for 'unsolved mysteries' (mikaiketsu jiken).

Yes, but it sounds a bit serious. For small daily things, people might say 'katazuita' (it's settled/done) or 'naotta' (it's fixed). Use 解決 when the issue felt like a real 'problem'.

It means 'a solution' or 'a measure to solve something'. 'Saku' means a plan or strategy. It is a very common word in business meetings.

Generally, no. For feelings like stress or anxiety, '解消する' (kaishō suru) is better. However, if you have a 'problem' with your feelings that needs a logical answer, you might use 解決.

The most direct opposite is '悪化する' (akka suru - to worsen) or '紛糾する' (funkyū suru - to become entangled/complicated).

Yes, it is a core vocabulary word for the JLPT N3 level and is essential for moving into the N2 level. It appears frequently in reading and listening sections.
