koto ga dekimasu – Can do something
Today I will cover the use of “koto ga dekimasu” which means “can do something”.
Example
Can speak Japanese – Nihongo o hanasu koto ga dekimasu
Cannot speak Japanese – Nihongo wa hanasu koto ga dekimasen
Meaning : Hanasu (Speak)
The verb shall be the original form (third sound) and it has to be placed just before the “koto ga…”. In the example above “hanasu” (sa shi su se so).
Another Example
Q : Can you make Japanese food? – Nihon ryōri o tsukuru kota ga dekimasu ka?
A : Yes, I can make Japanese food – Hai, nihon ryōri o tsukuru koto ga dekimasu
A : No, I cannot make Japanese food – Iie, nihon ryōri wa tsukuru koto ga dekimasen
Meaning : Ryōri (Food), Tsukuru (Make)
It’s easy. Go on, practise it and you should be able to master the usage in a short time.

I have a question. I see that you use o for dekiru and wa for dekinai. So, what would you use for a sentence like “kyou wa gakkou ni iku koto ga dekinai”? I know you could say “kyou wa gakkou ni ikenai” but is it possible to use dekiru/dekinai here?
Thanks a lot for making this site! Good information!

Hi Adam
Yes, you can use dekinai but “wa” should be used instead of “ga”
kyou wa gakkou ni iku koto
gawa dekinai“ga” is used when for “dekiru”
Hope this help

Hi Hanna,
You are correct.

Tony can we use noun before ga dekimasu. like ‘dansu ga dekimasu’
December 11th, 2008 at 4:33 pm
Hi Tya,
If you are referring to this lesson, then No. “koto ga dekimasu” can only use verb before “koto”
Thanks

Hello,
Can you say “Watashi wa Dansu suru koto ga dekimasu”?
Thanks
April 18th, 2009 at 10:41 am
Hi Bill,
Yes, you can use that. Nice try. Thanks

hi
would i say
neru koto ga dekinai
or
neru koto wa dekinai
??
thankyou
April 2nd, 2010 at 10:14 am
Hi Alex, should be “neru koto wa dekinai”
April 6th, 2010 at 9:41 pm
Hi Tony,
why is it “neru koto wa” und nicht “neru koto ga”?
In the lesson at the very top of this page you only write “koto ga”, never “koto wa”.
Thanks beforehand

LOL I mean “and not” instead of the German “und nicht”… ;o)
Sorry for that…

Hi Scelestion,
Well, this depend on the sentence. Most of the examples that I have posted above has a “noun” follow by “wa”. This is why “koto ga dekimasen” is used.
If noun is not being used before that, then koto wa dekimasen is used. In Japanese, most of the time a “noun” is used.
November 11th, 2010 at 10:43 am
wait so its wa if there is not noun and ga if there is a noun?
ex
sawaru WA dekimasen
Neko o sawaru GA dekimasen
are those right?
November 11th, 2010 at 10:44 am
***I mean Koto ga/ Koto wa

Hi:
Is there any difference between this and the ptnential form? I’m studying Japanese now, and we learned the potential conjugation for “can”.
I can sleep.
Neru koto ga dekiru
Vs.
Nerareru
Are they interchangable? If so, is one used more often/does one sound more natural?
May 19th, 2011 at 4:10 pm
Both are interchangeable. Most common is Nerareru

Hi!
Can I say “John san wa nihongo o dekimasu” ?
November 22nd, 2011 at 3:14 am
Rachel:
You always use the particle “ga” instead of “o” for dekiru. So it would be:
John san wa nihongo GA dekimasu
or
John san wa nihongo wo hanasu koto ga dekimasu

Awesome. Thanks alot!

Hi, Tony sensei.
Do you mean that if I do not add “watashi wa” to dansu suru koto ga dekimasu/dekinai, it would be just dansu suru koto wa dekimasu/dekinai? As in any sentence that started with a verb of a sentence would just be like “Verb + koto wa dekinai/dekimasu”?
September 28th, 2014 at 9:16 am
Hi Anna,
Yes, dansu suro koto wa dekinai is the correct grammar.
May 19th, 2016 at 10:50 am
“Watashi wa eigo o hanasu koto ga dekiru” what does that mean? is it “I can speak english?” hahaha I just done get it
May 19th, 2016 at 12:56 pm
Dette
Yes, that’s right

October 18th, 2018 at 9:45 am
Hi, excuse me,
May I said “fukyou wa kantan ni torisaru koto ga dekimasen.”? For the sentence “depression is not easy to remove.”?
October 18th, 2018 at 10:48 am
Hi Ion,
Yes, you can use that
January 6th, 2020 at 12:30 am

While refusing for something which i can not do…like i cannot play golf =私はゴルフができません。is it correct?
May 1st, 2020 at 10:23 am
Hi Jasleen,
The proper one should be 私がゴルフはできません
May 10th, 2020 at 2:19 pm
Is there a difference in the particles when using a subject as opposed to a noun. (apologies for romaji, I do not have a Japanese keyboard setting)
Are these examples correct,
1 – (subject) watashi ga oyogu koto wa dekimasen
2) (noun) nihon riyouri wa tsukuru koto ga dekimasen
Thank you!
