かかる

The Japanese verb かかる (kakaru) is one of the most fundamental and versatile words in the language, primarily introduced to learners at the CEFR A2 level with the meaning 'to take' in the context of time or money. However, its core underlying concept is much broader. Etymologically and conceptually, かかる implies that something is 'hanging onto,' 'suspended from,' or 'weighing upon' something else. When you say that a trip takes two hours, the Japanese phrasing essentially conveys that the burden of two hours is hanging upon the action of the trip. Similarly, when an item costs a certain amount of money, that financial burden is attached to the item or the purchaser. Understanding this core concept of 'attachment' or 'burden' is crucial for mastering not only the basic usages of time and money but also the dozens of advanced idioms and expressions that utilize this verb. In everyday conversation, you will hear かかる used constantly when discussing travel itineraries, daily commutes, shopping, project deadlines, and budgeting. It is an intransitive verb, meaning it does not take a direct object with the particle を (o). Instead, the time or money itself is the subject, or it acts adverbially without a particle. For example, 'It takes time' is 時間がかかる (jikan ga kakaru), where 'time' is the subject. If you specify an amount, like 'It takes one hour,' you simply say 1時間かかる (ichi-jikan kakaru) without any particle after the time word. This structural difference from English, where 'take' is a transitive verb taking 'time' as an object, is a critical point for learners to grasp early on.

Core Meaning: Time

Used to express the duration required to complete an action, travel to a destination, or finish a task. The time expression usually directly precedes the verb.

Beyond travel, this applies to any process. Cooking a complex meal, learning a new language, or repairing a broken appliance all 'take' time, and thus require かかる. The beauty of this verb lies in its simplicity; you do not need different verbs for different types of duration. Whether it is seconds, minutes, days, or decades, かかる is the appropriate choice. Furthermore, when discussing money, the logic remains identical. The cost is the burden attached to the acquisition of goods or services. If a new computer costs 100,000 yen, you say 10万円かかる (juu-man-en kakaru). This is slightly different from simply stating the price with です (desu). Using かかる emphasizes the *incurring* of an expense or the *requirement* of funds, often implying a sense of costliness or the necessity of preparation. It is frequently used when discussing budgets, estimates, or unexpected expenses.

Core Meaning: Money

Used to express the financial cost, expenses, or fees required for a service, item, or project. It emphasizes the incurring of a cost rather than just stating a price tag.

In addition to time and money, people use かかる in various physical and abstract contexts that relate back to the idea of 'hanging' or 'attachment.' For instance, when you catch a cold or a disease, the illness 'attaches' itself to you: 病気にかかる (byouki ni kakaru). When an engine starts, the mechanism 'engages' or 'catches': エンジンがかかる (enjin ga kakaru). When a bridge spans across a river, it 'hangs' over the water: 橋がかかる (hashi ga kakaru). When a trap is sprung and catches an animal, the animal is 'caught' in the trap: 罠にかかる (wana ni kakaru). These usages might seem disconnected to an English speaker, but in the Japanese linguistic mindset, they all share the same physical geometry of one thing being suspended upon, caught by, or burdened by another. Recognizing this underlying spatial and conceptual metaphor is the key to achieving fluency with this verb. You will hear it in train announcements ('The train arriving at track 1...'), in hospitals ('I caught the flu'), in mechanics' shops ('The engine won't start'), and in daily gossip ('That project is taking way too much money').

Extended Meaning: Illness

Used with the particle に (ni) to indicate contracting a disease or catching a cold. The illness is the target to which you become attached.

Mastering the sentence structure for かかる requires a solid understanding of Japanese particles, specifically が (ga) and に (ni), as well as the concept of adverbial nouns. Because かかる is an intransitive verb, it describes a state or an occurrence that happens naturally, rather than an action performed directly upon an object by a subject. Therefore, you will never use the direct object particle を (o) with かかる. This is the most critical grammatical rule to remember. When you want to say 'It takes time,' the word 'time' (時間 - jikan) is the subject of the sentence, not the object. Thus, the correct phrasing is 時間がかかる (jikan ga kakaru). The same applies to money: お金がかかる (okane ga kakaru). The particle が marks the thing that is being required or consumed. However, when you specify an exact amount of time or money, you typically drop the particle entirely. The amount functions as an adverb modifying the verb directly. For example, 'It takes three hours' is 3時間かかる (san-jikan kakaru), not 3時間がかかる. While the latter is not strictly ungrammatical in all contexts, it sounds unnatural in standard declarative sentences. The bare number + counter acts adverbially.

Syntax: Abstract Noun + が

When referring to time or money conceptually (without a specific number), use the subject marker が.

When you want to express the starting point and ending point of a journey or a process, you use the particles から (kara - from) and まで (made - until/to). This is a very common sentence pattern: [Place A] から [Place B] まで [Amount] かかる. For example, 'From Tokyo to Kyoto, it takes two hours' becomes 東京から京都まで2時間かかる (Tokyo kara Kyoto made ni-jikan kakaru). You can also add the means of transportation or the method using the particle で (de). So, 'From Tokyo to Kyoto by bullet train, it takes two hours' is 東京から京都まで新幹線で2時間かかる. This pattern is highly modular; you can swap out the places, the method, and the time amount to create thousands of useful sentences. The verb かかる always anchors the end of the sentence. Conjugating かかる follows standard Godan (Group 1) verb rules. The polite non-past is かかります (kakarimasu). The plain negative is かからない (kakaranai). The polite negative is かかりません (kakarimasen). The plain past is かかった (kakatta), and the polite past is かかりました (kakarimashita). The te-form, used for linking sentences or ongoing states, is かかって (kakatte).

Syntax: Specific Amount (No Particle)

When stating an exact duration or cost, place the amount directly before the verb without any particle.

For the other major usage of かかる—catching an illness or falling into a trap—the sentence structure shifts. Here, the illness or the trap is the target or destination of the action, so it takes the particle に (ni). The subject (which is often omitted if understood from context) is the person who gets sick or the animal that gets caught. For example, 'I caught a cold' is (私は)風邪にかかった (Watashi wa kaze ni kakatta). 'The bird was caught in the trap' is 鳥が罠にかかった (Tori ga wana ni kakatta). In these cases, かかる functions more like 'to fall into' or 'to succumb to.' Another very important structural use is with the te-form of other verbs to indicate that an action is currently in progress or that a state has been achieved and is continuing. However, this is usually seen in compound verbs or specific idiomatic structures, such as 立てかける (to lean something against) which comes from the transitive counterpart, but for the intransitive, you might see 寄りかかる (to lean on). Understanding the base conjugations and the strict rules regarding particles will prevent the vast majority of errors learners make with this essential verb.

Syntax: Target + に (Illness/Traps)

When expressing that someone has contracted a disease or been caught in a trap, the disease/trap takes the particle に.

Because かかる deals with the universal constraints of time and money, it is ubiquitous in daily Japanese life. You will hear it from the moment you wake up and turn on the news to the moment you set your alarm for the next day. One of the most common environments where かかる is spoken is in the context of transportation and travel. Japan's public transit system is famously punctual, and navigating it requires constant calculation of time. At train stations, you might ask a station attendant, '新宿までどのくらいかかりますか？' (How long does it take to Shinjuku?). Travel agencies and booking websites prominently feature the time required (所要時間) and the cost, often using phrases like '費用がかかる' (incurs expenses). When discussing daily commutes with colleagues, a standard conversation starter is asking how long their commute takes: '会社まで何分かかりますか？' (How many minutes does it take to get to the office?). In these contexts, かかる is not just a vocabulary word; it is the functional linchpin of logistical planning in Japanese society. You will also hear it frequently in business settings. Project management relies heavily on estimating resources. A manager might look at a proposal and sigh, saying, 'これにはかなり時間がかかりそうだ' (This looks like it will take quite a bit of time). Or, when reviewing a budget, they might point out, '開発にコストがかかりすぎる' (It costs too much for development).

Context: Travel & Commuting

Used constantly to discuss train rides, flights, walking distances, and the general logistics of getting from point A to point B.

Another major domain where かかる is inescapable is commerce and services. Whether you are at a hair salon, an auto repair shop, or a tailor, you will need to ask about the time and financial commitment. If you bring a broken smartphone to a repair shop, the clerk will evaluate it and tell you, '修理には1週間ほどかかります' (Repair will take about one week) and '料金は1万円かかります' (The fee will be 10,000 yen). In retail, while you might just ask 'いくらですか？' (How much is it?) for a simple item, if you are ordering custom furniture or requesting a special service, the language shifts to かかる to emphasize the process and the resources required. Furthermore, the healthcare environment is a critical place to understand this word. During flu season, public health announcements constantly warn people to wash their hands so they don't catch a cold: '風邪にかからないように注意してください' (Please be careful not to catch a cold). If you visit a doctor, they might ask if you have contracted any specific diseases in the past using this verb. The usage extends to mechanical issues as well. In the cold winter months, you might hear a neighbor struggling with their car, complaining, '寒くてエンジンがかからない' (It's cold and the engine won't start). This specific mechanical usage is very common for cars, lawnmowers, and other motor-driven machinery.

Context: Healthcare & Illness

Essential vocabulary for hospitals, clinics, and general health discussions regarding contracting viruses or diseases.

Finally, you will hear かかる in various idiomatic expressions that permeate everyday speech. A very common one is 迷惑がかかる (meiwaku ga kakaru), which means 'to cause trouble or inconvenience' to someone. In Japanese culture, avoiding causing meiwaku is a core social value, so this phrase is used frequently in apologies or warnings. '親に迷惑がかかる' (It will cause trouble for my parents). Another common idiom is 手がかかる (te ga kakaru), literally 'takes hands,' meaning something requires a lot of care, attention, or effort, often used for mischievous children or demanding pets. 'この子は本当に手がかかる' (This child is really a handful). You might also hear 気にかかる (ki ni kakaru), meaning something weighs on your mind or you are worried about it. These idiomatic usages demonstrate how deeply the concept of 'burden' or 'attachment' is woven into the psychological and social fabric of the language. By paying attention to these contexts—from the literal train schedules to the abstract social obligations—you will realize that かかる is not just a verb you learn; it is a verb you live with when speaking Japanese.

Context: Idioms & Social Relations

Used in set phrases to describe social burdens, worries, or the amount of effort required to manage relationships or tasks.

Because かかる translates to 'to take' in English, English speakers frequently project English grammar rules onto this Japanese verb, leading to several common and persistent mistakes. The most prevalent error is treating かかる as a transitive verb. In English, you say 'I take two hours' or 'The project takes time,' where 'time' is the direct object. Consequently, learners often try to use the direct object particle を (o) and say 時間をかかる (jikan o kakaru). This is fundamentally incorrect and sounds very unnatural to a native speaker. かかる is strictly intransitive. The time or money is the subject that 'exists' or 'is required,' so it must take the subject particle が (ga) resulting in 時間がかかる (jikan ga kakaru). If you want to use a transitive verb meaning 'to spend time/money actively,' you must use its transitive counterpart, かける (kakeru), as in 時間をかける (jikan o kakeru). Understanding the difference between the intransitive かかる (it takes time - out of my control) and the transitive かける (I spend time - my active choice) is a major milestone in mastering Japanese verbs. Always double-check your particles when using these verbs.

Mistake: Using the を (o) Particle

Incorrectly marking time or money as a direct object. かかる is intransitive and cannot take を.

Another frequent mistake arises from over-applying the English translation 'to take.' In English, 'take' is a highly versatile verb used for grabbing physical objects ('take a pen'), capturing images ('take a picture'), participating in classes ('take a course'), or consuming medicine ('take a pill'). Learners sometimes try to use かかる for all of these actions. This is a critical error. かかる only means 'to take' in the sense of requiring time or money (or in its specific idiomatic uses like catching a cold). If you want to say 'take a pen,' you must use 取る (toru). If you want to say 'take a picture,' you use 撮る (toru). If you want to say 'take a class,' you use 受ける (ukeru). If you want to say 'take medicine,' you use 飲む (nomu - literally 'to drink'). Using かかる in these contexts will result in complete incomprehension. For example, saying 写真がかかる to mean 'take a picture' makes no sense; it might be misinterpreted as 'a picture is hanging (on the wall).' You must mentally separate the English word 'take' into its distinct meanings and learn the specific Japanese verb for each context. Do not use かかる as a universal translation for 'take.'

Mistake: Using for Physical Objects

Attempting to use かかる to mean 'picking up' or 'grabbing' a physical item, which should be 取る (toru).

A third common pitfall involves the placement of particles when specifying exact amounts of time or money. As mentioned in the usage section, when you state a specific duration (like '3 hours') or a specific cost (like '1000 yen'), you generally do not use a particle between the amount and the verb かかる. Learners often try to force a particle in there, saying things like 3時間に掛かる (san-jikan ni kakaru) or 1000円がかかる (sen-en ga kakaru). While 1000円がかかる is sometimes acceptable in specific contexts where '1000 yen' is the grammatical subject being emphasized, it is usually more natural to treat the amount as an adverb and say 1000円かかる without the が. Using に after a duration (3時間に) is entirely incorrect when meaning 'it takes 3 hours.' The particle に indicates a point in time, a target, or a frequency, not a duration. Saying 3時間に掛かる sounds like you are saying something happens 'at the 3-hour mark' or 'per 3 hours,' which scrambles the intended meaning. The rule of thumb is: Abstract noun (Time/Money) + が + かかる. Specific amount (3 hours/1000 yen) + NO PARTICLE + かかる. Mastering this subtle difference in particle usage will instantly make your Japanese sound much more natural and native-like.

Mistake: Particles with Specific Amounts

Adding に or unnecessary が after a specific number representing duration or cost.

When expanding your Japanese vocabulary, it is essential to understand how かかる relates to and differs from similar words. The most immediate and important comparison is with its transitive counterpart, かける (kakeru). While かかる means 'to take (time/money)' in a passive, required sense, かける means 'to spend (time/money)' in an active, intentional sense. If a project naturally requires a lot of time, you say 時間がかかる (jikan ga kakaru). If you deliberately decide to invest a lot of time into making a project perfect, you say 時間をかける (jikan o kakeru). Notice the particle shift: が for the intransitive, を for the transitive. This transitive/intransitive pair is a fundamental feature of Japanese grammar. Another related word is 要る (iru), which means 'to need' or 'to be required.' You can often use 要る interchangeably with かかる when discussing money. For example, 'I need 10,000 yen' can be 1万円要る (ichi-man-en iru) or 1万円かかる (ichi-man-en kakaru). However, 要る is broader; you can need physical objects (ペンが要る - I need a pen), whereas かかる is strictly for time, money, or abstract burdens. You cannot say ペンがかかる to mean you need a pen. Furthermore, 要る focuses on the necessity of the item, while かかる focuses on the cost or duration being incurred.

Comparison: かける (kakeru)

The transitive equivalent. Means 'to actively spend or invest' time/money. Takes the を particle.

For more formal or written contexts, you might encounter the word 費やす (tsuiyasu), which means 'to spend, to consume, or to waste' time or money. 費やす carries a heavier nuance of exhausting a resource. While you would use かかる for a simple train ride ('It takes 10 minutes'), you would use 費やす for a major life endeavor ('I spent 10 years researching this topic' - この研究に10年を費やした). 費やす is transitive and takes the を particle. Another formal alternative is 必要とする (hitsuyou to suru), which means 'to require' or 'to necessitate.' This is often used in business or academic writing. Instead of saying 'This project takes a lot of money' (このプロジェクトはお金がかかる), a formal report might state 'This project requires substantial funding' (このプロジェクトは多額の資金を必要とする). While the meaning is similar, the register and tone are completely different. かかる is an everyday, conversational word, whereas 必要とする sounds objective and professional. Understanding these nuances allows you to tailor your speech to the appropriate level of formality, ensuring you sound natural whether you are chatting with a friend at a cafe or presenting a proposal in a corporate boardroom.

Comparison: 要る (iru)

Means 'to need'. Can be used for physical objects as well as money/time, focusing on necessity rather than the incurring of a burden.

When discussing illness, the alternative to 病気にかかる (to catch a disease) is 病気になる (to become sick). Both are very common, but にかかる sounds slightly more specific to contracting a contagious or specific illness (like the flu or a virus), whereas になる is a general statement of changing state from healthy to sick. You would say インフルエンザにかかる (catch the flu), but you are more likely to say 気分が悪くなる (feel sick/nauseous) rather than using かかる for a general feeling. For mechanical issues, instead of エンジンがかかる (the engine starts), you might hear 動く (ugoku - to move/operate). 'The machine won't start' could be 機械が動かない (The machine won't move/work). However, for engines specifically, かかる is the most idiomatic and natural choice. By learning these alternatives and their specific nuances, you build a robust and flexible vocabulary. You move beyond simple one-to-one translations and begin to understand the web of meanings that connect Japanese words. かかる is a central node in this web, connecting concepts of time, money, illness, mechanics, and social burdens through the shared metaphor of attachment and suspension.

Comparison: 費やす (tsuiyasu)

A formal, transitive verb meaning to spend, consume, or devote resources (time/money) to a specific cause or project.
