When someone says “Sorry!”, “Thank you!”, or worries that they caused a problem, you might want to say “No worries!” in Japanese.

But Japanese has several expressions depending on the situation!

Here are 4 useful expressions to know!

---

① 心配しないで（しんぱいしないで）

Meaning: Don’t worry / Don’t worry about it

Use 心配しんぱいしないで when you want to tell someone not to worry about something.

大たいしたことはありません。心配しんぱいしないでください。
→ It’s nothing serious. Please don’t worry.

もう元気げんきになりました。心配しんぱいしないでください。
→ I’m feeling better now. Please don’t worry.

💡 心配しんぱいする means “to worry,” so 心配しんぱいしないで literally means “don’t worry.”
💡 心配しんぱいしないでください is the polite version of 心配しんぱいしないで. Adding ください makes the expression more polite.

② 気にしないで（きにしないで）

Meaning: Don’t worry about it / Don’t mind it

Use 気きにしないで when someone is worried about a mistake, inconvenience, or something they did.

ごめん、コーヒーをこぼしちゃった！
→ Sorry, I spilled my coffee!

気きにしないで！
→ No worries! / Don’t worry about it!

💡 気きにする means “to mind” or “to be concerned about something.”
💡 気きにしないでください is the polite version of 気きにしないで. Adding ください makes the expression more polite.

So 気きにしないで is especially natural when reassuring someone that something isn’t a big deal.

③ 問題ない（もんだいない）

Meaning: No problem / There’s no problem

問題もんだいない is a straightforward way to say that there is no problem or issue.

ここに置おいてもいい？
→ Is it okay if I put it here?

うん、問題もんだいないよ。
→ Yeah, no problem.

It can sound a little more direct or matter-of-fact than 大丈夫だいじょうぶ.

💡 問題もんだいないです is the polite form of 問題もんだいない. Adding です makes the expression more polite.

④ 大丈夫（だいじょうぶ）

It can be used in many situations, including reassuring someone after an apology.
