When something opens by itself, or when a state of being closed changes to a state of being open, you use 「開く (ひらく)」.
It's important to remember that this verb is intransitive, meaning it doesn't take a direct object. Think of it as 'something opens' rather than 'someone opens something.'
For example, you can say ドアが開く (doa ga hiraku - the door opens) or 本が開く (hon ga hiraku - the book opens).
You wouldn't use this verb if you are the one actively opening something; for that, there's a different verb.
When you use the Japanese verb 「開く」 (hiraku), it means something opens by itself, or someone opens something. This verb is intransitive, so it doesn't take a direct object. Think of it like a door opening on its own, or a book opening in front of you. You'll often see it used when talking about things that become open without a specific person directly causing it. For example, a flower blooming or a store opening for business. It's a really useful verb to know for describing actions where the opening happens naturally or as a result of an outside force.
When you want to say that something opens by itself, like a door, a store, or an event, you use 「開く (あく)」. This is an intransitive verb, which means it doesn't take a direct object. Think of it as the subject itself performing the action of opening.
For example, if a store opens, you would say 「店が開く (みせがあく)」. If a door opens, it's 「ドアが開く (どあがあく)」. You wouldn't use this verb if someone or something else is actively opening it.
It's a very common verb, so pay close attention to its usage compared to its transitive counterpart, 「開ける (あける)」, which means "to open something." Mastering this distinction is key for natural Japanese.
When discussing Japanese verbs for "to open," it's crucial to understand the difference between transitive and intransitive verbs. 開く (aku) is an intransitive verb, meaning the action of opening happens by itself or the subject itself opens, without a direct object. For example, a door opens, or a store opens. It's often used when the focus is on the state of being open, or the spontaneous action of something opening.
You wouldn't use it to say "I open the door." For that, you would use the transitive verb 開ける (akeru), which means "to open something." The key difference lies in whether there's an agent directly performing the opening action on an object.
When discussing the verb 「開く」 (hiraku), it's important to understand its nuances, especially for English speakers learning Japanese. 「開く」 is an intransitive verb, meaning it doesn't take a direct object. This verb is used when something 'opens' by itself or is in an open state.
For example, you would use 「開く」 to describe a door opening on its own, a flower blooming, or a meeting commencing. The key takeaway is that the subject of the sentence is performing the action of opening, or the state of being open is happening to the subject, without an external agent directly acting upon it.
When you're dealing with the verb 「開く」 (hiraku), it's important to understand that it's an intransitive verb. This means it describes an action that happens to something, not an action that someone performs on something else. Think of it as 'something opens' rather than 'someone opens something'.
For example, you'd use 「ドアが開く」 (doa ga hiraku) to say 'the door opens' or 'the door is opening'. You wouldn't use it to say 'I open the door'. For that, you'd need the transitive counterpart, which is 「開ける」 (akeru).
So, if you see 「開く」, remember that the subject of the sentence is the thing that is doing the opening itself, or the thing that is in a state of being open.

§ What does 開く (aku) mean?
The Japanese verb 開く (aku) is a common and important word to know. It means 'to open' in an intransitive sense. This means that the action of opening happens on its own, or something opens by itself, without a direct agent performing the opening action. Think of it like 'the door opens' rather than 'I open the door'. This distinction is crucial in Japanese because there's often a separate verb for the transitive action (where someone or something performs the action). For 開く (aku), the transitive counterpart is 開ける (akeru), which means 'to open something'. We'll look at that another time, but for now, focus on the 'opens by itself' idea for 開く (aku).
- DEFINITION
- to open (intransitive) – meaning something opens on its own or happens to be open, often without a direct agent.
You'll encounter 開く (aku) in many everyday situations. It's used for doors, windows, books, stores, events, and even gaps or holes that become open. Understanding when to use the intransitive form versus the transitive form is a key step in sounding natural in Japanese.
§ When do people use 開く (aku)?
People use 開く (aku) in a variety of contexts. Here are some common situations:
- Doors and Windows: This is perhaps the most straightforward use. When a door or window simply opens, whether by itself (e.g., wind) or by someone else's action that isn't directly stated as the subject, you use 開く (aku).
- Stores and Businesses: When a store or business 'opens' for the day, or 'opens' its doors to customers, you use 開く (aku).
- Books and Eyes: You can use 開く (aku) when a book 'opens' or when someone's eyes 'open'.
- Events and Meetings: An event or meeting 'opening' (commencing) is another common use.
- Gaps or Holes: If a hole or gap 'opens up' or 'appears', you can use 開く (aku).
Let's look at some examples to make this clearer.
§ Examples of 開く (aku) in use
ドアが開く。
This translates to: The door opens. (The door itself performs the action of opening.)
店は9時に開く。
This means: The store opens at 9 o'clock. (The store begins its operation.)
目がぱっと開いた。
This translates to: My eyes suddenly opened. (The action of eyes opening happened to them.)
会議はまもなく開くでしょう。
This means: The meeting will probably open soon. (The meeting will commence.)
地面に穴が開いた。
This translates to: A hole opened in the ground. (A hole appeared.)
Notice how in all these examples, the subject of the sentence (ドア, 店, 目, 会議, 穴) is the thing that is 'opening' itself, or the state of being open happens to it, without an external agent actively opening it. This is the core concept of an intransitive verb like 開く (aku).
Keep an eye out for 開く (aku) as you consume Japanese content. You'll find it everywhere, and recognizing its intransitive nature will greatly improve your understanding and naturalness when speaking. Don't confuse it with its transitive cousin yet; master this form first!
§ Understanding 開く (hiraku)
So, you've learned that 開く (hiraku) means 'to open' and it's intransitive. This means the action happens by itself, or something opens without a direct agent. Think of a door opening by itself, or a flower blooming. You'll hear this word a lot in everyday Japanese, in all sorts of contexts. Let's break down where it pops up.

教室の窓が開いています。
- Hint
- The classroom window is open.
図書館は毎日午後5時まで開いています。

As you can see, 開く is a versatile word. Pay attention to the context to fully grasp its meaning in any given situation. The more you hear it, the more natural it will become to you.
§ Mistakes people make with 開く (aku)
The Japanese verb 開く (aku) means 'to open' but specifically refers to an intransitive action. This is a common point of confusion for English speakers, as 'to open' in English can be both transitive (someone opens something) and intransitive (something opens on its own). Understanding this distinction is crucial for using 開く correctly.
One of the biggest mistakes learners make is using 開く when they should be using its transitive counterpart, 開ける (akeru). Remember, if there's an agent performing the opening action, you need 開ける. If something opens by itself, or the focus is on the state of being open, then 開く is appropriate.
Let's look at some common scenarios where learners might misuse 開く:
§ Mistake 1: Using 開く with a direct object
You cannot use 開く directly with an object that is being opened. For example, you wouldn't say 「ドアを開く」 (doa o aku) to mean 'I open the door'. This is grammatically incorrect because 開く is intransitive.
Correct usage involves stating that the door opens:
ドアが開く。(doa ga aku)
- Definition
- The door opens.
If you want to say 'I open the door', you must use 開ける:
私がドアを開ける。(watashi ga doa o akeru)
- Definition
- I open the door.
§ Mistake 2: Confusing natural opening with intentional opening
開く is often used for things that open naturally or due to a circumstance, without a direct agent. For example, a flower blooming or a store opening for business. 開ける implies a deliberate action by someone.
Incorrect: 「店を開く」 (mise o aku) - if you mean someone opens the shop.
Correct: 「店が開く。」 (mise ga aku.) - The shop opens (e.g., at 9 AM).
Correct: 「店を開ける。」 (mise o akeru.) - (Someone) opens the shop.
§ Mistake 3: Overlooking the nuance in 'opening an event' or 'opening a meeting'
While 開く can be used in some idiomatic expressions that might feel transitive in English, like 'to open a meeting', the nuance in Japanese still leans towards the 'starting' or 'commencing' of an event, rather than someone actively opening a physical object.
会議が九時に開く。(kaigi ga kuji ni aku)
- Definition
- The meeting starts/opens at 9 o'clock.
However, if you want to emphasize the action of 'holding' or 'convening' the meeting, you might use other verbs or the transitive form with a different nuance.
§ How to avoid these mistakes: Focus on the subject
The easiest way to correctly choose between 開く and 開ける is to identify the subject of the sentence and the nature of the action:
If the subject is the thing that opens (e.g., the door itself), use 開く. The door opens.
If the subject is a person or agent who performs the opening action (e.g., I, she, he), use 開ける. I open the door.
Practicing with example sentences and paying close attention to contexts where native speakers use each verb will solidify your understanding. Don't be afraid to make mistakes; they are part of the learning process! Just remember the key difference: 開く is for things opening on their own, 開ける is for someone opening something.
How Formal Is It?
"自動ドアが開きます。 (The automatic door opens.)"
"ドアが開いた。 (The door opened.)"
"窓開いたよ。 (The window opened, you know.)"
"おもちゃばこがあいた！ (The toy box opened!)"
"店、まだ開かねぇの？ (Isn't the store open yet?)"
Curiosidade
The character '開' is a combination of '門' (gate) and '廾' (two hands), depicting hands opening a gate.

Gramática essencial
When referring to something opening on its own or by an unspecified agent, use 開く. For example, ドアが開く (doa ga hiraku - The door opens).
窓が開く (mado ga hiraku) - The window opens.
It's often used with the particle が (ga) to mark the subject that opens. For instance, 店が開く (mise ga hiraku - The shop opens).
本が開く (hon ga hiraku) - The book opens.
To express something opening as a result of an action, you can use the ~te form of a transitive verb (e.g., 開ける - akeru) followed by 開く. However, for just 'to open' intransitively, 開く is sufficient.
朝になると店が開く (asa ni naru to mise ga hiraku) - When morning comes, the shop opens.
It can be used for physical objects opening, like doors, windows, or books, but also for events or places opening, such as a store or a meeting.
会議が開く (kaigi ga hiraku) - The meeting starts/opens.
When speaking about something that opens regularly or habitually, you would use the dictionary form (開く) or the ます form (開きます) depending on the politeness level.
毎日、図書館は午前9時に開く (mainichi, toshokan wa gozen kuji ni hiraku) - Every day, the library opens at 9 AM.

Padrões gramaticais
Fácil de confundir
This verb can be tricky because it has two common readings, 「あく」 and 「ひらく」, and their usage depends on context.
「あく」 (aku) is an intransitive verb meaning 'to open' (e.g., a door opens by itself). 「ひらく」 (hiraku) can be either transitive or intransitive, but often implies a more deliberate or active opening, or something opening in a broader sense (e.g., a flower blooming, an event starting).
ドアが**開いた**。 (The door **opened**.) 店は9時に**開く**。 (The shop **opens** at 9 o'clock.) 本を**開く**。 (To **open** a book.) 会議を**開く**。 (To **hold** a meeting / To **open** a meeting.)
Like 開く, this verb also has a common variant, 閉める, which can cause confusion regarding transitivity.
「閉まる」 (shimaru) is an intransitive verb meaning 'to close' (e.g., the door closes by itself). 「閉める」 (shimeru) is a transitive verb meaning 'to close something' (e.g., I close the door).
ドアが**閉まった**。 (The door **closed**.) 店は5時に**閉まる**。 (The shop **closes** at 5 o'clock.)
This verb has a wide range of meanings and is often confused with 上げる due to similar kanji and related concepts.
「上がる」 (agaru) is an intransitive verb meaning 'to go up, to rise' (e.g., the price rises). 「上げる」 (ageru) is a transitive verb meaning 'to raise, to lift something' (e.g., I raise my hand).
値段が**上がった**。 (The price **went up**.) 階段を**上がる**。 (To **go up** the stairs.)
Similar to 上がる, its transitive counterpart 下げる often causes confusion.
「下がる」 (sagaru) is an intransitive verb meaning 'to go down, to drop' (e.g., the temperature drops). 「下げる」 (sageru) is a transitive verb meaning 'to lower, to hang something' (e.g., I lower the flag).
熱が**下がった**。 (My fever **went down**.) カーテンが**下がる**。 (The curtain **hangs down**.)
This verb is frequently confused with 入れる due to their close meanings and similar appearance.
「入る」 (hairu) is an intransitive verb meaning 'to enter, to go in' (e.g., I enter the room). 「入れる」 (ireru) is a transitive verb meaning 'to put in, to insert' (e.g., I put the key in the lock).
部屋に**入る**。 (To **enter** the room.) お風呂に**入る**。 (To **take** a bath / To **get into** the bath.)

Como usar
When 開く (hiraku) is used, it means something opens on its own, or something that you opened that wasn't designed to be opened by another person.
Imagine a flower blooming, a chasm opening up in the earth, a door swinging open because of the wind, or your eyes opening when you wake up. These are all natural actions. You can also use it when talking about opening a book or your mouth, or a store opening for business. These aren't objects that are opened by a specific mechanism or another person, like a door with a handle, or a new bank account.
The nuance is subtle but important. Think of it like this: if you actively manipulate a mechanism to open something, you'd likely use 開ける (akeru). But if something simply becomes open, or you're opening something like a book or your eyes, then 開く (hiraku) is the right choice.
A common mistake is using 開く (hiraku) when you should use 開ける (akeru). Remember, 開く (hiraku) is intransitive, meaning the action happens to the subject without a direct object performing the action. 開ける (akeru) is transitive, meaning someone or something performs the action of opening on a direct object.
For example, you wouldn't say ドアが私に開く (doa ga watashi ni hiraku - the door opens to me) if you're actively opening the door with your hand. Instead, you'd say ドアを私が開ける (doa o watashi ga akeru - I open the door).
Another mistake is using it for things like 'opening a bank account' or 'opening a new store' in the sense of establishing it. While 開く can be used for a store opening for business (お店が開く - omise ga hiraku), for establishing a new account or branch, you'd use different verbs like 開設する (kaisetsu suru - to establish/open).
Always consider whether the opening is a natural occurrence or an action performed by an agent on an object that is designed to be opened.
Dicas
Basic Meaning of 開く
開く (ひらく) means to open in an intransitive sense. This means the action happens to the object itself, without a direct agent performing the opening.
Common Usage with Doors and Windows
You'll often hear 開く used for things like doors and windows. For example, ドアが開く (doa ga hiraku) means the door opens.
Use with Books and Eyes
開く can also be used for books or eyes. 本が開く (hon ga hiraku) means the book opens, and 目が開く (me ga hiraku) means eyes open.
Distinction from 開ける (transitive)
It's important to distinguish 開く (ひらく) from 開ける (あける). 開ける is transitive, meaning someone or something performs the action of opening on an object. For example, ドアを開ける (doa o akeru) means (I) open the door.
When to Use Each
Use 開く when you want to say something opens on its own or is open. Use 開ける when you want to say someone opens something.
Focus on the State, not the Agent
When using 開く, the focus is on the state of being open or the action of opening itself, not on who or what caused it to open.
Example: 店が開く
店が開く (mise ga hiraku) means the shop opens. Here, the shop itself is performing the action, not someone opening the shop.
Example: ページが開く
ページが開く (pēji ga hiraku) means the page opens (e.g., on a website or in a document). The page just opens.
Avoid Direct Translation
Don't directly translate 'to open' from English without considering transitivity. Always think if an agent is performing the action or if the object is simply opening.
Practice with Intransitive Verbs
Practice using 開く with other intransitive verbs (e.g., 閉まる 'to close', 始まる 'to start') to get a better feel for their usage pattern.
Memorize
Mnemônico
Imagine a **door A K**icking open by itself. **A K U** sounds like 'aku', the common reading for 'to open' (intransitive). The door 'opens' by itself, which helps you remember it's intransitive.

Perguntas frequentes
10 perguntasBoth mean 'to open', but 開く (hiraku) is intransitive, meaning the action happens by itself or the subject is not directly doing the opening. Think 'the door opens'. 開ける (akeru) is transitive, meaning someone or something performs the action of opening. Think 'I open the door'.
Sure. ドアが開く (Doa ga hiraku). This means 'The door opens.' The door is opening by itself, or it's the subject experiencing the action.
No, it can also refer to non-physical things. For example, 窓が開く (mado ga hiraku - 'The window opens'), or 予定が開く (yotei ga hiraku - 'My schedule opens up').
Here are some basic conjugations:
- Present/Future: 開く (hiraku) - 'opens/will open'
- Past: 開いた (hiraita) - 'opened'
- Negative: 開かない (hirakanai) - 'doesn't open'
- Te-form: 開いて (hiraite) - 'opening/and open'
Yes, the polite form is 開きます (hirakimasu). For example, ドアが開きます (Doa ga hirakimasu) - 'The door opens (polite).'
Use the intransitive form (開く) when you want to emphasize that something is opening on its own, or when you don't know/don't want to specify who or what is doing the opening. Use the transitive form (開ける) when there's a clear agent performing the action.
Yes, for example, 目が開く (me ga hiraku) means 'eyes open' or figuratively 'to realize something'. 店が開く (mise ga hiraku) means 'The store opens'.
The kanji 開 means 'to open'. The radical 門 (mon) means 'gate' and 廾 (kyou) represents two hands, so it visually suggests hands opening a gate.
Yes, besides ひらく (hiraku), it can also be read as あく (aku). Both mean 'to open' intransitively, but ひらく often implies a wider or more significant opening (like a book or a meeting), while あく is more common for physical openings like doors or windows. For example, 本が開く (hon ga hiraku - 'The book opens'), ドアが開く (doa ga aku - 'The door opens').
Generally, あく is used for simple physical openings (doors, windows, holes). ひらく is used for a broader range of meanings, including opening books, holding events, starting businesses, or metaphorical openings. If in doubt, あく is often a safe bet for basic physical openings, but understanding the nuances comes with practice.

Choose the most appropriate sentence using 「開く」 (hiraku - to open, intransitive) to describe a meeting starting.
「会議が開かれた」 (kaigi ga hirakareta) means 'The meeting was opened/held.' This is the correct usage for a meeting starting, as it's often described as 'being opened' in a formal sense. 「会議を開いた」 (kaigi wo hiraita) would mean 'I/someone opened the meeting,' making it transitive. 「ドアが開いた」 (doa ga aita) means 'The door opened,' and 「店が開かれた」 (mise ga hirakareta) means 'The shop was opened.'
Which sentence correctly uses 「開く」 (hiraku - to open, intransitive) to describe a gap or space appearing?
「二人の間に距離が開いた」 (futari no aida ni kyori ga aita) means 'A distance opened up between the two of them.' This correctly uses 「開く」 intransitively to describe a gap forming. 「私は窓を開いた」 (watashi wa mado wo aita) is incorrect; it should be 「開けた」 (aketa) for transitive 'opened the window.' 「本が開かれた」 (hon ga hirakareta) means 'The book was opened,' using the passive form. 「彼が店を開いた」 (kare ga mise wo hiraita) means 'He opened the shop,' which is transitive.
Select the sentence where 「開く」 (hiraku - to open, intransitive) is used to describe a schedule becoming available.
「今週末、時間が開いていますか？」 (konshūmatsu, jikan ga aiteimasu ka?) means 'Do you have time available this weekend?' or 'Is your schedule open this weekend?' This is a common and correct idiomatic use of 「開く」 for availability. 「彼は本を開いた」 (kare wa hon wo hiraita) means 'He opened the book,' transitive. 「店は朝10時に開く」 (mise wa asa jūji ni hiraku) means 'The shop opens at 10 AM,' which is also intransitive but refers to a physical opening. 「ドアが開かれた」 (doa ga hirakareta) means 'The door was opened,' in passive form.
The sentence 「彼が窓を開いた」 (Kare ga mado o aita) is a correct use of 「開く」 (hiraku) as an intransitive verb meaning 'to open.'
False. 「開く」 (hiraku) is an intransitive verb. To say 'He opened the window' (transitive), you should use 「開ける」 (akeru), so the correct sentence would be 「彼が窓を開けた」 (Kare ga mado o aketa). 「窓が開いた」 (Mado ga aita) would mean 'The window opened,' which is intransitive.
「本が開く」 (Hon ga hiraku) correctly conveys 'The book opens' (intransitive).
True. 「本が開く」 (Hon ga hiraku) correctly uses 「開く」 as an intransitive verb to mean 'The book opens,' implying it opens by itself or is in a state of being open.
In the phrase 「話が大きく開いてしまった」 (Hanashi ga ōkiku hiraite shimatta), 「開く」 (hiraku) implies a conversation topic becoming too broad or straying significantly.
True. In this context, 「話が大きく開いてしまった」 (Hanashi ga ōkiku hiraite shimatta) means 'The conversation (topic) has branched out too much' or 'The discussion has diverged widely,' using 「開く」 to describe the expansion or spreading of a topic.

Summary
Use 開く when something opens on its own or is in an open state, not when someone actively opens it.
- intransitive verb
- something opens by itself
- no direct agent
Basic Meaning of 開く
開く (ひらく) means to open in an intransitive sense. This means the action happens to the object itself, without a direct agent performing the opening.
Common Usage with Doors and Windows
You'll often hear 開く used for things like doors and windows. For example, ドアが開く (doa ga hiraku) means the door opens.
Use with Books and Eyes
開く can also be used for books or eyes. 本が開く (hon ga hiraku) means the book opens, and 目が開く (me ga hiraku) means eyes open.
Distinction from 開ける (transitive)
It's important to distinguish 開く (ひらく) from 開ける (あける). 開ける is transitive, meaning someone or something performs the action of opening on an object. For example, ドアを開ける (doa o akeru) means (I) open the door.
