Questions & Answers about kore ga genjitsu desu.
In これが現実です, が marks これ as the specific thing being identified.
So the sentence has the feeling of:
- This is reality.
- This is the reality.
It gives focus to これ.
If you say これは現実です, that is also correct, but it feels a bit different. は sets これ up as the topic, while が highlights it more directly. In a dramatic or emphatic statement, が often sounds very natural.
So:
- これが現実です = more focused, often more emphatic
- これは現実です = more neutral as a topic-comment statement
これ means this and refers to something close to the speaker, either physically or conceptually.
Japanese has a common three-way set:
- これ = this, near me
- それ = that, near you or something already mentioned

In this sentence, これ points to something the speaker is presenting as reality. It could be:
- a situation happening right now
- a fact being discussed
- something visible in front of the speaker
- a harsh truth the speaker wants to emphasize
