Hiraku vs. Akeru: What’s the Difference in Japanese?

“Hiraku” or “akeru”? If you’ve ever tried to say “open the door” in Japanese, you may have wondered which one to use.

Both 開く (hiraku) and 開ける (akeru) can be translated as “to open,” but they are used differently. The good news? Once you understand the basic pattern, the difference is actually quite simple.

Hiraku vs. Akeru: The Simple Rule

Think of it this way:

• 開く (hiraku) → something opens
• 開ける (akeru) → someone opens something

The difference is mainly about what is doing the opening.

1. 開く (Hiraku): Something Opens

開く (hiraku) focuses on something opening or becoming open.

For example:

ドアが開きます。
Doa ga hirakimasu.
→ The door opens.

本を開きます。
Hon o hirakimasu.
→ I open a book.

店が開きます。
Mise ga hirakimasu.
→ The shop opens.

With hiraku, the emphasis is often on the thing that opens or the state changing from closed to open.

2. 開ける (Akeru): Someone Opens Something

開ける (akeru) focuses on a person opening something intentionally.

For example:

ドアを開けます。
Doa o akemasu.
→ I open the door.

窓を開けてください。
Mado o akete kudasai.
→ Please open the window.

箱を開けました。
Hako o akemashita.
→ I opened the box.

Notice an important pattern:

• ～が開く → something opens
• ～を開ける → someone opens something

This particle difference is a great clue when you’re deciding between hiraku and akeru.

Hiraku vs. Akeru Examples

Compare these two sentences:

ドアが開きました。
Doa ga hirakimashita.
→ The door opened.

ドアを開けました。
Doa o akemashita.
→ I opened the door.

The first sentence describes what happened to the door. The second tells us that someone opened the door.

An Easy Way to Remember

Ask yourself:

“Am I saying that something opened, or that someone opened something?”

• Something opens → hiraku
• Someone opens something → akeru

It’s a small distinction, but learning it will help you sound much more natural in Japanese.
