Translation guide
A guide to expressing the idea of 'at most' in Japanese, covering limits on quantity, degree, and time, as well as the 'at best' nuance.
To say that something is no more than a certain amount or number.
This is the most common and natural way to express 'at most' for quantities. It implies 'only' or 'no more than' and often carries a nuance of 'that's not much'.
この店には、せいぜい10人しか入れません。
At most, only ten people can fit in this shop.
I have at most about 5000 yen.
Literally 'even if it's many', this is a straightforward way to state a maximum. It is slightly more formal than せいぜい.
参加者は多くても20人だろう。
There will be at most 20 participants.
Means 'at maximum'. Used in more technical or formal contexts, such as specifications or statistics.
このエレベーターは最大で10人まで乗れます。
This elevator can carry at most 10 people.
To say that something will take no longer than a certain amount of time.
Literally 'even if it's long', this is the most natural way to express a maximum duration.
修理には長くても1週間かかります。
The repair will take at most one week.
Also works for time, but often implies the duration is surprisingly short or insignificant.
彼はせいぜい5分しか待てない。
He can wait at most five minutes.
To express that something is only as good as a certain (often mediocre) level, or to downplay expectations.
Used before a noun or adjective phrase to mean 'at best'. It often has a dismissive or realistic tone.
彼の英語はせいぜい中学レベルだ。
His English is at most junior high school level.
この映画はせいぜい可もなく不可もなしだ。
This movie is at best mediocre.
Means 'merely' or 'only'. It strongly belittles the thing mentioned. Use with care as it can sound arrogant.
たかが一回の失敗で落ち込むな。
Don't get depressed over at most one failure.
Literally 'at best' or 'if it goes well'. Used to give a generous estimate, often when the reality is likely worse.
よくて相槌を打つ程度だ。
At most, he just gives non-committal responses.
To state a maximum in formal documents, rules, or technical descriptions.
Means 'not exceeding' or 'or less'. Used after a number. Very common in formal contexts.
応募資格は30歳以下です。
Applicants must be at most 30 years old.
Means 'within' a time or distance. Implies 'at most' that amount.
せいぜい often carries a nuance of 'only' or 'that's not much', implying the speaker thinks the amount is small. 多くても is a more neutral, factual statement of a maximum.
せいぜい1000円だ。
It's at most 1000 yen (and that's cheap).
多くても1000円だ。
It's at most 1000 yen (factual maximum).
Do not directly translate 'at most' as 最も (mottomo, 'most') or 最大限 (saidai gen, 'maximum limit'). These are not used in the same way and will sound unnatural.
It's at most a 5-minute walk from the station.
