Translation guide
How to say 'no problem' in Japanese depends on the situation: responding to thanks, agreeing to a request, or saying something is easy. The most common and versatile phrase is 大丈夫 (daijoubu).
You want to say 'you're welcome' or 'it was nothing' after someone thanks you.
The standard modest reply to thanks, literally 'no'. It downplays the favor.
A: Thank you. B: No problem.
A polite 'you're welcome'. Slightly more formal than いいえ, but can sound a bit stiff in casual settings.
A: That was helpful. B: You're welcome.
Casual 'don't worry about it', literally 'don't mind'. Used among friends.
A: Sorry I'm late. B: No problem.
Very casual 'not at all'. Often used by younger speakers. Can sound blunt if overused.
A: Thanks! B: No problem!
Someone asks you to do something or asks for permission, and you want to say 'sure, no problem'.
Casual 'sure, okay'. Very common among friends. The よ adds a reassuring tone.

Versatile 'it's okay, no problem'. Can be used in both casual and polite contexts.

大丈夫 (daijoubu) is more about 'it's okay, safe, all right' and is used for reassurance. 問題ない (mondai nai) is more logical, meaning 'there is no problem/issue'. In many cases they overlap, but 大丈夫 is more common in daily conversation.
A: Are you okay? B: Yeah, no problem.
English 'no problem' is often used as a casual reply to 'thank you'. In Japanese, 問題ない is not used this way. Use いいえ or どういたしまして instead.
