Translation guide
Expresses that an action or state continues or lasts for a certain period of time. The length can be vague or context-dependent. Japanese uses various adverbial phrases and patterns depending on whether the time is long, short, or unspecified.
The action or state continues for a considerable duration, often implying 'for quite a while' or 'for a long time'.
Literally 'for a long time'. Neutral and widely used for durations that feel long to the speaker.
He has been living here for a long time.
Means 'for a while' or 'for some time'. Can be used for both short and moderately long periods. Very common in spoken Japanese.
Emphasizes continuity 'all the time' or 'the whole time'. Often used with verbs in ～ている form.
The action or state lasts for a brief period, often implying 'for a little while'.
Literally 'for a short time'. Polite and clear.
The duration is not clearly defined; it could be long or short depending on context. Often used when the exact length is unknown or unimportant.
Adds の間 to しばらく for a slightly more formal or explicit 'for a while'. Suitable for both spoken and written Japanese.
Indicates a temporary state or action that will last for an unspecified but limited period, often with the implication that it may change later.
Means 'for the time being' or 'for a while'. Suggests the situation will continue for the foreseeable future but is not permanent.
しばらく is more flexible and can mean a short or long time depending on context. 長い間 explicitly means a long time. Use しばらく when the duration is vague or when you want to be polite (e.g., しばらくお待ちください). Use 長い間 when you want to emphasize the length.
Please wait a moment. (polite, short wait)
Sorry to have kept you waiting for so long.
しばらくお待ちください。
Please wait for a moment.
I haven't seen you for some time, have I?
He was talking for a long time.
Please wait here for a little while.
Casual version of 少しの間. Used in everyday conversation.
Close your eyes for a moment.
Also works for short durations, especially in requests like 'please wait a moment'.
Stay here for a bit.
He didn't show up for some time.
Means 'for a certain period of time'. More formal and often used in business or official contexts.
This situation will continue for some time.
This store will be closed for some time.
Adds は to しばらく to emphasize 'at least for a while'. Often used when contrasting with a future change.
It's fine like this for the time being.
I'm sorry to have kept you waiting for so long. (apologizing for a long wait)
English 'for' in time expressions is not translated as ために. ために expresses purpose or reason, not duration. Use ～間 or adverbial phrases like しばらく instead.
I waited for a long time. (incorrect)
I waited for a long time. (correct)
