借ります (借りる)

The Japanese verb 借ります (karimasu), or its dictionary form 借りる (kariru), is a fundamental Group 2 (Ichidan) verb that primarily translates to "to borrow" or "to rent" in English. At its core, it signifies the act of receiving something from another person or entity with the explicit understanding and intention that the item, or its equivalent value, will be returned at a later time. This concept of temporary possession is vital in Japanese culture, where the exchange of favors and the maintenance of social harmony (wa) often revolve around the careful management of borrowed goods and obligations. Unlike English, which might distinguish between 'borrowing' a pen and 'renting' a car, Japanese often uses kariru for both, provided the item is being taken from someone else's possession into your own.

Primary Meaning

The act of taking something for temporary use with the intent to return it.

Secondary Meaning

To rent a space, vehicle, or service (e.g., renting an apartment or a tuxedo).

Abstract Meaning

To 'borrow' someone's help, wisdom, or influence (e.g., 'borrowing a hand' for assistance).

In a linguistic sense, kariru describes the direction of movement toward the speaker or the subject. It is the exact opposite of 貸す (kasu), which means 'to lend.' Understanding the relationship between these two verbs is crucial for Japanese learners, as the particles used with them define the social dynamics of the transaction. When you borrow something, you are entering into a small social contract. In Japan, this is often accompanied by a sense of 'on' (obligation), meaning that the act of borrowing is not just a physical transaction but a social one that requires gratitude and a timely return to maintain the relationship's balance.

The verb also extends to the concept of 'renting.' For instance, when you rent an apartment, you use the term heya o kariru. While there are more specific words like chintai (lease), in daily conversation, kariru is the go-to verb. This versatility makes it one of the most frequently used verbs in the Japanese language, appearing in contexts ranging from the classroom to high-level business negotiations. It encompasses the borrowing of money (shakkin), the borrowing of ideas (aidea o kariru), and even the metaphorical borrowing of power or authority (tora no i o karu kitsune - the fox who borrows the tiger's authority).

Ichidan Verb (Group 2) - Ends in -iru.

Transitivity

Transitive Verb (requires an object marked by 'o').

Furthermore, the nuances of kariru involve a specific mindset regarding the condition of the item. In Japanese culture, there is a strong emphasis on returning the item in the same, if not better, condition than it was received. This is often reflected in the phrase karita mono wa kaesu (return what you borrowed), which is a basic moral tenet taught from childhood. The verb carries the weight of this cultural expectation. Whether it's a physical object or a conceptual favor, kariru initiates a cycle of exchange that is central to Japanese social life.

Politeness Levels

Kari-ru (Plain), Kari-masu (Polite), O-kari-shimasu (Humble).

Using 借ります (karimasu) correctly requires an understanding of Japanese particle markers and verb conjugation. As an Ichidan (Group 2) verb, it is relatively straightforward to conjugate. You simply drop the final -ru and add the appropriate suffix. For example, the polite form is kari-masu, the negative form is kari-nai, and the past form is kari-ta. This consistency makes it a favorite for beginners, but the complexity lies in the sentence structure surrounding it.

Basic Sentence Pattern

[Borrower] は [Lender] に/から [Object] を 借ります。

The most important thing to remember is the particle に (ni) or から (kara). Both are used to indicate the person or institution you are borrowing from. While ni is more common for individuals (friends, family), kara is often used for organizations or when the 'source' aspect is emphasized. For example, ginkou kara okane o kariru (borrow money from a bank). If you use the wrong particle, such as to (with), the sentence might imply you are borrowing the item together with someone else, which changes the meaning entirely.

When conjugating for different levels of politeness or intent, keep the following in mind: Use the -te form (karite) when asking for permission or combining verbs. A common phrase is karite mo ii desu ka? (May I borrow this?). This is the standard way to ask for something in a classroom or office setting. If you want to be even more polite, you might say o-kari shite mo yoroshii deshou ka?. The humble form o-kari suru is essential when speaking to a boss or a client, as it lowers your status while acknowledging the favor they are doing for you.

In the context of 'renting,' kariru is used for things like apartments (apaato o kariru), cars (kuruma o kariru), or even DVD rentals (though streaming has made this less common). In these cases, the transaction usually involves money (chingan or ryoukin). If you are borrowing something for free, it is still kariru, but the social obligation is higher. In business, you might 'borrow' a room for a meeting (kaigishitsu o kariru). The verb remains the same, but the context of payment or professional courtesy is implied by the setting.

Potential Form

Karirareru (Can borrow). Often shortened to 'karireru' in casual speech.

Passive Form

Karirareru (To be borrowed). Used when the object is the focus.

Finally, consider the 'Te-morau' construction. If someone does you the favor of letting you borrow something, you might say karite moratta (I had them let me borrow it). This emphasizes the gratitude toward the lender. In Japanese, the focus is rarely just on the object; it is on the relationship between the borrower and the lender. Therefore, choosing the right form of kariru or its causative/passive variations is key to sounding natural and respectful.

You will encounter 借ります (karimasu) in a wide variety of daily life scenarios in Japan. One of the most common places is the library (toshokan). From the moment you enter, signs will explain how many books you can kariru and for how long. The staff will ask, "Nan-satsu karimasu ka?" (How many books are you borrowing?). This is a great place to practice the verb in a low-stakes, formal environment. Similarly, in a school or university setting, students frequently borrow notes, pens, or dictionaries from one another, making kariru a staple of campus life.

In the business world, the verb takes on a more professional tone. You might hear it during a meeting when someone says, "Chotto o-mimi o kashite kudasai" (Please lend me your ear/listen for a moment), or when discussing resources: "Hoka no bushu kara hito o kariru" (Borrowing staff from another department). In the banking sector, kariru is the standard term for taking out a loan. When you visit a bank to discuss a mortgage or a personal loan, the consultant will use kariru to describe the principal amount being borrowed. Here, the language becomes very formal, often utilizing the humble o-kari ni naru or o-kari suru forms.

The travel and hospitality industry is another major area. If you are at a hotel and need an extra blanket or a charger, you would ask to kariru those items. Car rental agencies are literally called rentakaa-ya, but the action of renting the car is kuruma o kariru. Even at a traditional Japanese inn (ryokan), you might kariru a yukata or a bicycle to explore the surrounding area. In these service-oriented contexts, the staff will use very polite language (keigo) to facilitate the borrowing process, often saying "O-kari ni narimasu ka?" (Would you like to borrow/rent one?).

Public Announcements

"Borrowed items must be returned by 5 PM." (Kari-ta mono wa gogo go-ji made ni henkyaku shite kudasai.)

Real Estate

"Renting a house" (Ie o kariru) is the standard phrase in housing ads.

Finally, you'll hear it in casual social gatherings. If you're at a friend's house and need to use their phone or charger, you'd say "Juudenki, karite mo ii?" (Can I borrow the charger?). In Japanese media, such as anime or drama, characters often use kariru to express deep gratitude or to set up a plot point involving a debt. The phrase "Kari o kaesu" (to return a favor/debt) is a common trope where a character performs a heroic deed to repay someone who helped them in the past. This highlights how kariru is woven into the very fabric of Japanese storytelling and social ethics.

One of the most frequent mistakes English speakers make is confusing 借りる (kariru) with 貸す (kasu). In English, the words 'borrow' and 'lend' are distinct, but learners often mix them up because they describe the same transaction from different perspectives. Remember: Kariru is 'to take' (borrow), and Kasu is 'to give' (lend). A helpful mnemonic is that Kariru starts with 'K' like 'Keep' (temporarily), and Kasu is what the other person does. If you say "Pen o kashite kudasai," you are asking someone to lend you a pen. If you say "Pen o karimasu," you are stating that you are borrowing it.

The 'Ni' vs. 'To' Error

Using 'to' (with) instead of 'ni' (from). 'Tomodachi to kariru' means you and your friend are borrowing something together from a third party.

The 'Kasu' Confusion

Saying 'Watashi wa tomodachi ni hon o karimashita' when you actually lent the book. (Correct for lending: 'kashimashita').

Another common error involves the particles. Many learners use o (object marker) correctly for the item being borrowed but struggle with the source. You must use ni or kara for the person you are borrowing from. For example, "Sensei ni jisho o karimashita" is correct. Using "Sensei no jisho o karimashita" (I borrowed teacher's dictionary) is also grammatically correct but focuses on the ownership of the dictionary rather than the act of borrowing from the teacher. While subtle, the ni version is more common when emphasizing the transaction.

Learners also often forget that kariru is an Ichidan verb. Some try to conjugate it like a Godan verb, saying "kariranai" instead of "karinai" or "karimasu" correctly but failing on the plain negative. Remember: drop the -ru and add. It's not karu (which is a different verb meaning 'to shear' or 'to hunt'). Confusing kariru with karu can lead to very strange sentences, like saying you are 'hunting' a book instead of borrowing it. Always double-check the 'ri' in ka-ri-ru.

Finally, there's the issue of politeness and social context. In Japan, borrowing something is a favor. Simply saying "Kariru yo" (I'm borrowing this) to a superior is very rude. You should use the -te mo ii desu ka form or the humble o-kari shimasu. Failing to acknowledge the 'debt' of the favor is a social mistake. Even if you are borrowing a small item like a stapler, a quick "sumimasen, arigatou gozaimasu" upon return is expected. Neglecting this cultural nuance makes the use of the verb feel incomplete or 'gaijin-ppoi' (foreigner-like) in a negative way.

While 借りる (kariru) is the most general term for borrowing, several other words have overlapping meanings but different nuances. Understanding these will help you choose the right word for the right situation. The most common synonym in a commercial context is レンタル (rentaru). While you can use kariru for a rental car, the business itself is a 'rental' service. Rentaru usually implies a short-term, commercial agreement with a fixed fee, whereas kariru can be free or paid, and can be between friends.

借用 (shakuyou)

A formal, often written term for borrowing. Used in legal documents or formal requests (e.g., 'shakuyousho' - a promissory note).

拝借 (haishaku)

The extra-humble (kenjougo) version of kariru. Used when borrowing something from someone of much higher status.

賃貸 (chintai)

Specifically refers to 'leasing' or 'renting' property. You 'kariru' an apartment, but the contract is a 'chintai' agreement.

Another related word is 借り受ける (kariukeru). This is a more formal version of kariru, often used in business or official contexts to mean 'to take charge of' or 'to rent/borrow' something formally. For example, a company might kariukeru a piece of land from the government. It sounds more official and implies a formal handover process. On the other hand, karidasu (to borrow and take out) is often used in libraries to describe the act of checking out books.

It's also important to distinguish kariru from 貰う (morau). Morau means 'to receive' or 'to get' something permanently. If you borrow a pen, you must return it (kariru). If someone gives you a pen as a gift, you morau it. Learners sometimes use kariru when they actually mean they were given something, which can lead to confusion when the 'lender' expects the item back! Similarly, kariru is different from yoyaku suru (to reserve), though you might yoyaku a book before you kariru it.

Lastly, consider 借金 (shakkin). This is the noun form for 'debt' or 'borrowed money.' While you use the verb okane o kariru to describe the act, shakkin describes the state of owing. There is also kari (a debt/favor), used in phrases like "Kari ga aru" (I owe you one). Understanding these variations allows you to navigate the complex social web of Japanese transactions with precision, ensuring you don't accidentally sound too formal or too casual.
