Translation guide
To express approximation in Japanese, you can use adverbs, suffixes, or particles depending on whether you're talking about quantities, time, or general vagueness. The most common and versatile word is 約 (yaku), but other options like くらい/ぐらい (kurai/gurai) and ほど (hodo) are also essential for natural speech.
Expressing that a number or amount is not exact, often used in formal or written contexts.
Placed before a number or quantity. Common in both spoken and written Japanese, neutral formality.
Approximately 100 people participated.
ここから駅まで約2キロです。
It's about 2 kilometers from here to the station.
Similar to 約 but slightly more formal or literary. Often used in written language or formal speech.
そのプロジェクトにはおよそ1年かかりました。
The project took approximately one year.
Means 'almost' or 'nearly', implying a very close approximation. Often used when the difference is negligible.
仕事はほぼ終わりました。
The work is almost finished.
ほぼ全員が賛成した。
Almost everyone agreed.
Expressing a rough estimate in everyday conversation, often with a sense of 'more or less'.
Attached after a quantity, time, or degree. くらい and ぐらい are interchangeable, though ぐらい is more common after certain sounds. Very common in casual speech.
10分くらい待って。
Wait about 10 minutes.
それぐらい簡単だよ。
It's about that easy.
Similar to くらい but slightly more formal or literary. Often used in written language or polite speech. Can also imply an extent or degree.
100人ほどの人が集まった。
About 100 people gathered.
Used after a number to mean 'approximately' or 'around', often for time or age. More formal than くらい.
Indicating that something is not exact but generally true, often used with adjectives or verbs.
Means 'mostly', 'roughly', or 'generally'. Can be used with numbers, but also with statements to mean 'for the most part'.
だいたい分かりました。
I more or less understand.
だいたい同じです。
It's roughly the same.
Kanji form of だいたい, same meaning. Slightly more formal in writing.
Specifically for giving approximate times, dates, or durations.
Used after a time expression to mean 'around' or 'about'. ころ is used after words, ごろ after specific times. Very common.
3時頃に会いましょう。
Let's meet around 3 o'clock.
来月の終わり頃
around the end of next month
Also used with time expressions, interchangeable with 頃 in many cases, but slightly more casual.
5分くらい遅れる。
I'll be about 5 minutes late.
Both mean 'approximately' or 'about', but くらい is more common in casual speech, while ほど is slightly more formal and often used in written language or polite conversation. ほど can also imply an extent ('as much as'), so context matters.
泣きたいくらい嬉しい。
I'm so happy I could cry.
泣きたいほどうれしい。
I'm so happy I could cry. (more emphatic/literary)
While 約 is correct, using くらい/ぐらい or だいたい sounds more natural in everyday conversation. 約 can sound stiff or overly precise in casual contexts.

The meeting will last approximately two hours.
今日は30度くらいです。
It's about 30 degrees today.
