تمرین کن مثال‌ها نکات و راهنمایی‌ها 回収する در ۳۰ ثانیه

توضیح 回収する in your Level:

At the A1 level, you only need to know 'kaishū suru' in the context of daily chores, specifically garbage collection. In Japan, trash isn't just 'thrown away'; it is 'collected' by the city. You might see this word on posters in your apartment building. Think of it as 'bringing things together to take them away.' It is usually used with the particle 'wo' like 'gomi wo kaishū suru' (collect trash). Don't worry about the complex business meanings yet; just focus on the idea of a truck coming to pick up things you've put outside. It is a polite and official way to talk about cleaning up the neighborhood.

At the A2 level, you can start using 'kaishū suru' in classroom or office settings. If you give someone a piece of paper and then need it back, you 'kaishū' it. For example, 'Please collect the handouts' (shiryō wo kaishū shite kudasai). You will also notice this word on recycling boxes for plastic bottles or batteries at the supermarket. It implies a cycle: the item was used and is now being returned to be processed. You should understand that this word is more formal than 'atsumeru' (to gather). Use it when there is a specific rule or system for picking things up.

At the B1 level, you should be comfortable using 'kaishū suru' in various professional and social contexts. This includes 'jishu-kaishū' (voluntary recalls) of products, which you might hear about in the news. You should also understand the nuance of 'recovery.' For example, if a company spends money on an advertisement, they want to 'kaishū' that cost through increased sales. In this level, the word moves from just physical objects to more abstract concepts like 'recovering costs' or 'collecting data.' You should also be aware of the passive form 'kaishū sareru,' which is very common in formal announcements.

At the B2 level, you should master the nuance of 'kaishū' versus other synonyms like 'shūshū' or 'saishu.' You should understand that 'kaishū' strongly implies a 'return to the origin' or 'retrieval of distributed items.' You will encounter this word in literary discussions regarding 'fuseu-kaishū' (resolving foreshadowing). This is a high-level metaphorical use where the author 'collects' the hints they dropped earlier. In business, you'll use it for 'shikin-kaishū' (capital recovery) and understand the strategic implications of how and when assets are retrieved.

At the C1 level, your understanding of 'kaishū suru' should include its use in complex socio-economic and technical contexts. This includes the 'kaishū' of space capsules, the recovery of deep-sea sensors, or the systematic collection of high-level intelligence. You should be able to use the word in formal reports and debates, distinguishing it from 'chōshū' (collection of fees/taxes) and 'toritateru' (debt collection). You will also recognize its use in environmental policy discussions regarding 'shigen-kaishū-ritsu' (resource recovery rates) and the circular economy.

At the C2 level, you have a native-like grasp of 'kaishū suru' across all registers. You can use it metaphorically in philosophy or advanced literary criticism to describe the synthesis of disparate ideas or the resolution of complex narrative structures. You understand the legal and administrative nuances of 'kaishū' in product liability law and international trade. You can navigate the most formal business negotiations regarding 'tōshi-kaishū-keikaku' (investment recovery plans) with precision, ensuring that the term's systematic and accountable connotations are fully utilized.

回収する در ۳۰ ثانیه

Systematic collection of distributed items (trash, surveys).
Formal term for product recalls and debt recovery.
Used in storytelling for resolving foreshadowing (plot points).
Implies items returning to a source or central point.

The Japanese verb 回収する (かいしゅうする - kaishū suru) is a sophisticated and essential term primarily used to describe the act of collecting, retrieving, or recovering items that have been distributed or are no longer needed in their current location. At its core, it implies a systematic process where objects are brought back to a central point or returned to an original owner or authority. This isn't just 'picking something up' like a coin on the street; it carries a nuance of organized management and purpose.

Administrative Collection: Used when a company or organization gathers questionnaires, documents, or tests after they have been completed. For example, a teacher collecting exam papers at the end of a class would use this term.
Waste and Recycling: The most common daily encounter with this word is in the context of garbage collection. Municipalities 'kaishū' burnable waste, plastics, and recyclables on specific days. It emphasizes the systematic removal of items for processing.
Product Recalls: In a business or legal context, if a product is found to be defective or dangerous, the manufacturer will issue a recall. In Japanese, this is described as the 'kaishū' of the product to ensure consumer safety and mitigate risk.

テストが終わったら、解答用紙を回収します。
Once the test is finished, I will collect the answer sheets.

The word consists of two kanji: 回 (kai) meaning 'round' or 'revolving,' and 収 (shū) meaning 'obtain' or 'gather.' Together, they create the image of something going out and then coming back into a central fold. This cyclical nature is why it is so heavily associated with recycling and resource management. When you use 回収する, you are signaling that there is a plan or a designated destination for the items being gathered.

メーカーは欠陥が見つかった製品を急いで回収している。
The manufacturer is hurriedly recalling (collecting) the products where defects were found.

Financial Context: In business, it can refer to the recovery of invested funds (投資の回収) or the collection of debts. It implies getting back the value that was previously put out into the market or lent to another party.

Whether you are a student handing in a survey, a citizen putting out the trash, or a business professional managing a logistics crisis, 回収する is the precise, formal verb you need to describe the purposeful gathering of distributed assets or materials. It bridges the gap between simple physical movement and systematic organizational management.

Using 回収する correctly requires understanding its grammatical placement as a Transitive Suru-Verb. This means it almost always takes a direct object marked by the particle を (wo). The structure is typically: [Subject] が [Object] を回収する.

The Passive Form: 回収される: Often used in news reports or official announcements where the focus is on the items being collected rather than the person doing it. Example: 'The trash is collected on Mondays' (ゴミは月曜日に回収される).
The Potential Form: 回収できる: Used to discuss the possibility or feasibility of recovery, such as 'Can we recover the costs?' (コストを回収できるか？).

アンケートを回収してください。
Please collect the questionnaires.

In professional settings, you will frequently see the noun form 回収 (kaishū) used in compound nouns. Common examples include 回収予定 (kaishū yotei - scheduled collection) and 回収業者 (kaishū gyōsha - collection agency/contractor). Understanding these compounds is vital for navigating life in Japan, especially regarding waste management rules.

この地域では、ペットボトルは週に一度回収されます。
In this area, plastic bottles are collected once a week.

When discussing the recovery of funds or investments, the verb often pairs with terms like 資金 (shikin - funds) or 投資 (tōshi - investment). In these cases, it doesn't mean physically picking up money, but rather the business successfully earning back the amount spent, reaching a break-even point or profit.

Polite Requests: In an office, you might say '回収に伺います' (kaishū ni ukagaimasu), meaning 'I will come to collect [the items].' This uses the humble verb 'ukagau' to show respect to the person from whom you are collecting.

Finally, consider the timing. 回収する usually implies a deadline or a specific window of time. If you are collecting something indefinitely or without a plan, 集める (atsumeru) might be more appropriate. Use 回収する when there is a 'return to base' logic involved.

You will encounter 回収する in several distinct environments, ranging from the mundane chores of daily life to high-stakes corporate announcements. Recognizing these contexts will help you grasp the word's inherent formality and systematic nature.

1. Residential Life and Garbage Days: If you live in Japan, you will see this word on every 'Garbage Collection Calendar' (ごみ回収カレンダー). On the morning of collection, you might hear the garbage truck's music or announcements over loudspeakers regarding 'shigen-gomi no kaishū' (collection of recyclable resources). It is the standard term for public sanitation services.
2. Corporate and Retail Environments: Retailers often have 'kaishū-box' (回収ボックス) near entrances for used batteries, plastic bottle caps, or old clothing (like at UNIQLO). In the office, a manager might say, 'Please collect the visitor badges at the end of the seminar' (セミナーの最後に、来客用バッジを回収してください).

古着の回収にご協力ください。
Please cooperate in the collection of old clothes.

Another unique place you'll hear this word is in the world of literature, cinema, and anime. Critics and fans discuss 'fuseu-kaishū' (伏線回収). When a character mentions a small detail in episode 1 that becomes the key to the finale in episode 24, fans will exclaim about how beautifully the 'fuseu' (foreshadowing) was 'kaishū-ed' (collected/resolved). It implies that the narrative 'debt' has been paid or the 'scattered' story elements have been brought back together for a satisfying conclusion.

あの映画は、最後にすべての伏線を回収した。
That movie collected (resolved) all the foreshadowing at the end.

3. Scientific and Space Exploration: When a space probe like Hayabusa returns to Earth with soil samples, the process of finding and picking up the capsule in the desert is called 'kaishū.' Similarly, collecting data from remote sensors in the ocean is 'dēta no kaishū.'

In summary, 回収する is heard wherever there is a need for order, safety, or resolution. It is a word of accountability and systematic completion, making it a staple of formal and functional Japanese communication.

While 回収する is a versatile word, English speakers often confuse it with other Japanese verbs that translate to 'collect' or 'pick up.' Understanding these distinctions is crucial for sounding natural.

Mistake 1: Using it for Hobbies (Confusing with 収集): If you collect stamps or anime figures as a hobby, do not use 'kaishū.' Instead, use 収集する (shūshū suru) or 集める (atsumeru). 'Kaishū' implies things are being returned or gathered for a functional reason (like recycling), not for personal enjoyment or curation.
Mistake 2: Using it for Random Discovery (Confusing with 拾う): If you find a 100-yen coin on the ground and pick it up, that is 拾う (hirou). 'Kaishū' requires a systematic intent. You wouldn't 'kaishū' a random shell on the beach unless you were part of a scientific team systematically 'collecting' samples.

❌ 趣味で切手を回収しています。
I collect stamps as a hobby. (Incorrect nuance)
✅ 趣味で切手を収集しています。
I collect stamps as a hobby. (Correct)

Another common error is forgetting that 回収する is a transitive verb. Learners sometimes try to use it to mean 'the items are gathering' (intransitive), but in Japanese, you must specify who is doing the collecting or use the passive form 回収される.

❌ 資料が回収しました。
The documents collected. (Grammatically wrong)
✅ 資料が回収されました。
The documents were collected. (Correct)

Finally, be careful with the word 徴収 (chōshū). This is specifically for collecting taxes, fees, or dues (often by force or legal obligation). While 'kaishū' can be used for debt recovery in business, 'chōshū' is the more specific term for government or institutional fee collection. Using 'kaishū' for taxes would sound slightly off to a native speaker.

Japanese has many words for 'collecting.' Choosing the right one depends on the context, the items being collected, and the formality of the situation. Here is a comparison of 回収する with its closest relatives.

集める (Atsumeru): The most common and general word for 'to gather.' It can be used for people, objects, or information. Unlike 'kaishū,' it doesn't imply that the items were distributed beforehand or are being returned to a source. Use this for: 'gathering friends,' 'collecting data,' or 'picking flowers.'
収集する (Shūshū suru): A more formal version of 'atsumeru,' often used for hobbies (stamp collection) or academic research (data collection). It is very similar to 'kaishū,' but 'shūshū' focuses on the act of gathering for accumulation, whereas 'kaishū' focuses on retrieval or recovery.
採取する (Saishu suru): Specifically used for taking samples from nature or the human body. Use this for: 'collecting blood samples,' 'gathering botanical specimens,' or 'extracting oil.' It implies a scientific or technical process.

データを収集して、分析する。
Collect data and analyze it. (Focus on accumulation)
アンケートを回収して、集計する。
Collect questionnaires and tally them. (Focus on retrieval)

In business, you might also hear 取り立てる (Toritateru). This is a much more aggressive word for collecting debts or taxes. While 'kaishū' can refer to recovering an investment calmly, 'toritateru' sounds like a debt collector knocking on your door. Choose 'kaishū' for professional, systematic recovery and 'toritateru' only when describing the forceful demand for payment.

'Kaishū' is transitive. You must either say you collected them or they were collected.
Using 'kaishū' for collecting people. → 集める (Atsumeru)

Remember the first kanji 回 (turn/round). It helps you remember that things are coming 'back around' to you.

Transitive Verb

Always remember it needs an object. You 'kaishū' something. It doesn't just happen by itself.

Garbage Timing

Look for the word 'kaishū' on your city's garbage calendar to know exactly when and what is being picked up.

Recalls

If you see 'kaishū' on a poster in a grocery store, check it! It usually means a product is being recalled for safety.

Surveys

If you are doing research, the number of returned surveys is your 'kaishū-sū' (collection count).

Cooperation

Often paired with 'kyōryoku' (cooperation). 'Kaishū ni go-kyōryoku kudasai' is a very common polite phrase.

Space Recovery

بافت فرهنگی

Be careful when using 'kaishū' for money; if you mean debt collection in a harsh way, 'toritateru' is used, but in a professional business setting, 'kaishū' is safer.

English speakers often say 'pick up' or 'get' for many situations where Japanese specifically requires 'kaishū' (like for trash or surveys).

Jishu-kaishū (Voluntary Recall) news headlines from Toyota or Sony. Anime fan theories about 'fuseu-kaishū' in series like One Piece or Attack on Titan. Gomi-kaishū (Garbage Collection) schedules in every Japanese city.
