How to use it
Used when wanting to do something while an opportunity still exists, or when a gradual change occurs while continuing an action or state.
- 「～うちに」 places an action or change within the time during which the state in the first clause still holds. When talking about an opportunity, the speaker implies that state may end soon.
- This pattern can also describe a change that gradually appears, which the subject doesn't necessarily bring about intentionally: by continuing the action in the first clause, at some point one notices the result in the second clause.
- Compared to 「～間に」, 「～うちに」 emphasizes more the limit of an opportunity or a change in state. If you're just stating that an event occurs within a time span, 「～間に」 is usually more neutral.
Examples
桜が咲いているうちに、家族と花見に行きたい。
I want to go cherry-blossom viewing with my family while the blossoms are still in bloom.
毎日この町を歩いているうちに、細い路地まで覚えた。
As I walked around this town every day, I gradually learned even its narrow alleys.
若いうちに、いろいろな経験をしたほうがいい。
You should have many experiences while you are young.
Keep in mind
- To say "before an undesired state occurs," the negative form is often used, as in 「暗くならないうちに」.
- Nouns connect with 「の」, while na-adjectives connect with 「な」.
Common mistakes
-
Wrong夏休みなうちに、北海道へ行きたい。
While it's still summer vacation, I want to go to Hokkaido.
Correct夏休みのうちに、北海道へ行きたい。
「夏休み」 is a noun, so it must connect to 「うちに」 with 「の」, not 「な」.
-
Wrong暗くなるうちに、家へ帰ろう。
Go home before it gets dark.
Correct暗くならないうちに、家へ帰ろう。
When you want to say "go home before it gets dark", use 「暗くならないうちに」 to place the action before the state changes.
-
Wrong元気のうちに旅行したい。
While I'm still healthy, I want to travel.
Correct元気なうちに旅行したい。
na-adjectives connect via 「な」.
-
Wrong暗くなるうちに帰ろう。
Let's go home before it gets dark.
Correct暗くならないうちに帰ろう。
The meaning "before" uses the ない form.
Exam tips
- Check whether the sentence emphasizes a fading opportunity or a gradual change; these are the two main uses of 「～うちに」.
