あける

akeru

When you want to talk about opening something like a door or a window, you'll use the Japanese verb あける (akeru).

It's a really useful verb to know for everyday situations. For example, if you want to let some fresh air in, you might say, "窓をあける" (Mado o akeru), which means "I open the window."

Remember, this verb is specifically for things that you can actively open. It's an action you perform. So, you wouldn't use it for something like a flower opening, for example.

When you want to say "to open" something like a door or a window in Japanese, you'll use the verb あける (akeru). This is a common and practical verb to know.

You'll often hear it in everyday situations, for example, when asking someone to open a window or when talking about opening a store. Remember, it generally refers to opening things that have a clear opening mechanism, like doors, windows, or even a box.

It's a regular -ru verb, so its conjugations are quite straightforward. Mastering あける will definitely help you navigate daily conversations in Japanese.

When using 「あける」 (akeru), it means to open something like a door, a window, or a box. It's a transitive verb, which means it takes a direct object. For example, you would say 「ドアをあける」 (doa o akeru) to mean "open the door."

It can also be used in some idiomatic expressions. For instance, 「目をあける」 (me o akeru) means "to open one's eyes." Another common use is 「店をあける」 (mise o akeru), meaning "to open a store" for business.

Be careful not to confuse it with 「ひらく」 (hiraku), which also means "to open." While they share some overlap, 「ひらく」 often implies a more gradual or wider opening, or opening something like a book or a meeting. 「あける」 is generally for more straightforward physical openings.

Therefore, when you want to express the action of physically opening a specific object like a door or a window, 「あける」 is the verb you should use.

When discussing the verb "あける" (to open), it's important to differentiate it from similar concepts to ensure precise communication, which is crucial at the C1 level. While "あける" typically refers to physically opening something like a door or a window, it doesn't usually extend to abstract concepts such as opening a bank account or a new business, for which different verbs would be used. For instance, to "open an account," you would typically use 「口座を開設する」 (kouza o kaisetsu suru), employing 「開設する」 which specifically means to establish or set up. Similarly, for "opening a business," verbs like 「開業する」 (kaigyou suru) or 「開店する」 (kaitesn suru) are more appropriate, depending on the context of establishing a new practice or a new store respectively. Understanding these nuances allows for more natural and accurate expression in complex Japanese.

あける in 30 Seconds

  • Commonly used for opening doors, windows, and boxes.
  • It's a transitive verb, meaning it takes a direct object.
  • Can also be used for unwrapping or unlocking.

§ What does 「あける」 mean?

The Japanese verb 「あける」 (akeru) means "to open." It's a really common verb you'll hear and use a lot, so understanding it well is key. Think of it as opening something that was previously closed.

Meaning
To open (a door, window, etc.).

「あける」 is a transitive verb, which means it needs a direct object. You "open *something*." This is important because Japanese has another verb, 「あく」 (aku), which also means "to open," but it's intransitive. We'll talk about that more later, but for now, remember that 「あける」 is when *you* are doing the opening.

§ Common Situations to Use 「あける」

You'll use 「あける」 in many everyday situations. Here are some of the most common ones:

  • Opening a door
  • Opening a window
  • Opening a box or container
  • Opening a book
  • Opening an umbrella

§ Examples of 「あける」 in action

Let's look at some practical examples so you can see how 「あける」 is used naturally in sentences:

ドアをあけてください。

This means: "Please open the door." This is a polite request.

窓をあけてもいいですか。

This means: "May I open the window?" This is how you politely ask for permission.

箱をあける

This simply means: "To open a box." This is a more direct, statement-like usage.

Notice how the particle 「を」 (o) is used with 「あける」 to mark the direct object. The thing being opened comes before 「を」.

§ Transitive vs. Intransitive: A Quick Note

While this section focuses on 「あける」, it's helpful to briefly mention its partner verb 「あく」 (aku). They both mean "to open," but as mentioned, 「あける」 is transitive (someone opens something), and 「あく」 is intransitive (something opens on its own or is in an open state).

  • 「あける」 (akeru): You open the door. (ドアをあける)

  • 「あく」 (aku): The door opens. (ドアがあく)

Don't worry too much about mastering both right now, but keep this distinction in the back of your mind as you learn more. For now, focus on using 「あける」 when you are performing the action of opening something.

§ Understanding あける (akeru)

The Japanese verb あける (akeru) means 'to open'. It's a common and very useful verb to know. You'll hear it and use it a lot in daily conversation. It's used for opening things like doors, windows, and even boxes.

Japanese Word

Meaning
To open (a door, window, etc.)
CEFR Level
A2

§ Basic Sentence Structure with あける

When using あける, the basic sentence structure is straightforward. You typically use the object particle を (o) to mark the thing being opened.

The pattern is: [Object] を あける

ドアをあけてください。

Here, ドア (doa) means 'door', and ください (kudasai) makes it a polite request, 'please'. So, "Please open the door."

§ Examples with different objects

You can use あける with many different objects. Here are a few common ones:

  • 窓 (mado) - window
  • 窓をあけてもいいですか。

    "May I open the window?" (もいいですか (mo ii desu ka) means 'Is it okay to...?' or 'May I...?')

  • 箱 (hako) - box
  • プレゼントの箱をあけました

    "I opened the present box." (プレゼント (purezento) is 'present' and の (no) is a possessive particle here. あけました (akemashita) is the polite past tense of あける.)

  • 本 (hon) - book
  • 本をあけて、読み始めました。

    "I opened the book and started reading." (読み始めました (yomihajimemashita) means 'started reading'.)

§ あける vs. ひらく

You might also encounter another verb, ひらく (hiraku), which also means 'to open'. While they often overlap, there's a nuance. あける is generally used for physical objects that have an opening mechanism, like doors, windows, and eyes.

ひらく is often used for things that 'unfold' or 'spread out', like books, flowers, or events (like 'opening' an event). However, for books, both can sometimes be used.

§ Common phrases with あける

Here are some useful phrases:

  • ドアをあける (doa o akeru): To open the door
  • 窓をあける (mado o akeru): To open the window
  • 目をあける (me o akeru): To open one's eyes
  • 朝、目をあけて、コーヒーを飲みます。

    "In the morning, I open my eyes and drink coffee."

Practice using あける with different objects. The more you use it, the more natural it will feel.

Frequently Asked Questions

10 questions

あける (akeru) is used for opening things like doors, windows, or boxes where there's a clear opening action. ひらく (hiraku) is often used for opening things that unfold, like a book, an umbrella, or an event. Think of あける as 'to make open' and ひらく as 'to become open' or 'to unfold'.

Yes, you can use あける for opening a shop, as in '店をあける' (mise o akeru - to open a shop). It means the shop starts its business for the day.

The polite form of あける is あけます (akemasu). For example, 'ドアをあけます' (doa o akemasu - I will open the door).

あける (akeru) is a transitive verb, meaning it takes a direct object. You 'open something'. The intransitive counterpart, meaning something 'opens by itself', is あく (aku).

You would use 口をあける (kuchi o akeru) to say 'open your mouth'.

Yes, you can use プレゼントをあける (purezento o akeru) for 'opening a present'.

The past tense of あける is あけた (aketa) in plain form, and あけました (akemashita) in polite form.

A common idiom is 目をあける (me o akeru), which means 'to open one's eyes'. It can also metaphorically mean 'to realize something'.

While technically you are 'opening' an account, for a bank account, you typically use 口座を開設する (kouza o kaisetsu suru) which means 'to open/establish an account'. あける isn't the most natural choice here.

You would use the intransitive form, 窓があく (mado ga aku) for 'the window opens'. To say 'automatically', you could add '自動的に' (jidouteki ni), making it 窓が自動的にあく (mado ga jidouteki ni aku).
