"There are keys in the pocket."

Translation: ポケットの中に鍵があります。

[CameronMit3]

Should "poketo ni" rather than "poketo no naka ni" be correct as well?

[Keith_APP]

Both are correct. の中 makes it specific that they are <inside> the pocket.

[T33K3SS3LCH3N]

Seems a bit superfluous for pockets in particular.

[Keith_APP]

Only in this case. に indicates a location but it does not say where at that location. It can be in, on, at, over, …
e.g.
ポケットに刺繍があります。
There is embroidery on the pocket.
ポケットの中に刺繍があります。
There is embroidery inside the pocket.

are certainly different.

Is it me, or does the voice for ギ in カギ sound like "ngi"?

[MikeWillisUK]

If I remember correctly from reading other comment sections in the past (and I'm far from an expert)... It's a regional thing, so some people in Japan will pronounce their 'g's like that, while others won't.

[luca.bittarello]

Some Japanese may pronounce /g/ as /ng/. It depends on the speaker and the region. Wikipedia discusses it: https://en.m.wikipedia.org/wiki/Japanese_phonology

[Stacey_Dono]

I think it sounds like kami which can't be right...xD

[Keith_APP]

Still gi to my ears…

[hollt693]

Yeah, I heard it too.

Is "oite arimasu" ok?

[IsolaCiao]

That would mean that someone has put the keys in the pocket for a purpose.

I tried writing カギ in kanji (鍵), and got marked wrong. I'm guessing it being written in katakana is more common. Still, I don't see why I should be marked wrong for that. Reporting.

[IsolaCiao]

Japanese is still in beta, and a lot of the questions don't accept kanji. We just have to keep submitting error reports.

[Dai803021]

It's not regional in this case. It's just being said wrong, as "kami". The same voice says "kagi" clearly in the full sentence.
