Translation guide
A casual, friendly way to agree to a request or express certainty. In Japanese, the best equivalent depends on the situation: casual agreement, polite confirmation, or enthusiastic acceptance.
Responding to a request or suggestion with a friendly 'of course' or 'no problem'.
Very common casual agreement. Literally 'it's good', used like 'sure' or 'okay'.
"Can you help me?" "Sure thing."
Means 'of course'. Slightly more emphatic than いいよ, but still casual.
"Are you coming tomorrow?" "Sure thing."
Literally 'leave it to me'. Used when someone asks you to handle something.
"Can you take care of this?" "Sure thing."
Agreeing to a request or confirming something in a polite or neutral setting.
Very polite, often used in service situations. Equivalent to 'certainly' or 'very well'.
"I'd like to make a reservation." "Sure thing."
Formal 'understood' or 'certainly'. Common in business contexts.
Literally 'yes, with pleasure'. Warm and polite, but less formal than かしこまりました.
"Shall I help?" "Sure thing."
Expressing strong, happy agreement, like 'absolutely!' or 'you bet!'.
Saying that something is a sure thing, i.e., guaranteed or definite.
Do not translate 'sure thing' literally as 確かなこと (tashika na koto) when agreeing to a request. That sounds unnatural and means 'a certain thing' as a noun phrase.
"Please send the documents." "Sure thing."
