Translation guide
The English word 'soon' refers to something happening in the near future. In Japanese, the most common equivalent is すぐ (sugu), but the best choice depends on whether you mean 'immediately,' 'in a little while,' 'before long,' or 'as soon as possible.' Japanese also uses specific grammar patterns like 〜たらすぐに and 〜次第 to express 'as soon as X happens.'
Expressing that something will happen without delay, at once.
The most common and versatile word for 'soon' in the sense of 'immediately' or 'right away.' Can be used in both casual and formal contexts.
すぐ戻ります。
I'll be right back.
すぐに始めましょう。
Let's start right away.
A formal, often written word meaning 'immediately' or 'at once.' Used in official announcements, instructions, or emergencies.
Implies doing something promptly, often with a sense of eagerness or without wasting time. Commonly used when you start something right after receiving it or hearing about it.
Expressing that something will happen in the near future, but not necessarily instantly.
Expressing urgency or a desire to do something without delay.
The standard phrase for 'as soon as possible.' It is polite and can be used in most situations.
できるだけ早くご返信ください。
Please reply as soon as possible.
Expressing that one action will happen immediately after another.
Attach to the past tense of a verb to mean 'as soon as (I) do X.' This is the most common conversational pattern.

As soon as I get home, I wash my hands.
Emphasizing that one event happened immediately after another, often with surprise.
Used to express that something happened right after something else, often unexpectedly. Attach to the past tense of a verb.
すぐ means 'immediately' or 'right away,' focusing on the lack of delay. もうすぐ means 'soon' in the sense of 'before long,' focusing on the nearness of an event. For example, すぐ行きます (I'll go right away) vs. もうすぐ行きます (I'll go soon, in a little while).
English speakers often default to すぐ for every 'soon,' but すぐ implies immediacy. If you mean 'in the near future' without urgency, use もうすぐ or 近いうちに instead. Saying すぐ結婚します (I'll get married right away) sounds odd unless you mean literally today or tomorrow.
