I tried (at least) to construct a sentence. However, when I showed it to a native-speaker and asked if it was correct they did not understand. But I can't see what is wrong with it...


What I tried to say:

Yesterday I took a nap for an half hour.

Is this sentence incomprehensible?

  • Where did you learn to say 時半間? Dec 22 '16 at 13:26
  • @l'électeur Ohh, is the proper way to say it 半時間? Don't think I learned it anywhere if it's considered incorrect. I must have just done it wrong.

  • @macraf The sentence was in text-format on the app HiNative.

By 「時半間」, you probably meant to say 「半時間{はんじかん}」 for "half an hour", but still we do not say 「半時間」 in Standard Japanese. We say 「30分{ぷん}」.

I have heard that they say 「半時間」 to mean "half an hour" in Kansai (around Osaka, that is), but I am not sure if it is true. Hope someone can confirm this.

Also important is that you do not need to place a particle after 「30分」. It is not even optional; You cannot use a particle there.

So, you will have:


  • even 30分の昼寝 doesn't work? I found this: mezamashi.jp/suimin/hirune Dec 22 '16 at 19:05
  • 30分の昼寝 is fine as a noun phrase. When I said no particle was needed, I meant "in the sentence OP is trying to form". In other words, I meant when 30分 was directly followed by a verb. All I wanted to say was that to say "did something for 30 minutes", you do not use a particle after 30分. Dec 23 '16 at 0:43
