How to Make Negative Requests in Japanese with ないでください
Sometimes you need to ask someone not to do something. In Japanese, the most common way to make a polite negative request is with ないでください.
Meaning
ないでください means:
“Please don’t…”
It’s polite and commonly used in everyday conversations, signs, and announcements.
Formation
To make a negative request:
Verb (ない form) + でください
Examples:
- 食べないでください → Please don’t eat.
- 話さないでください → Please don’t talk.
- 入らないでください → Please don’t enter.
- 写真を撮らないでください → Please don’t take photos.

Common Situations

ないでください vs な
Another way to tell someone not to do something is な.
Compare:
- 入らないでください。
- Please don’t enter.
- 入るな。
- Don’t enter!
- 話さないでください。
- Please don’t talk.
- 話すな。
- Don’t talk!
ないでください is polite and suitable for most situations.
な is much stronger and sounds like a direct command. You’ll often hear it in movies, anime, sports, or when someone is angry.
For everyday conversations, ないでください is usually the safer choice.
Casual Version
When speaking with friends or family, you can often drop ください.
- 忘れないで。
- Don’t forget.

This sounds more casual but is still softer than using な.
