kore ga genzitu 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
• あれ = that over there, away from both of us

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

Yes. 現実 is a noun.

In this sentence, the structure is basically:

• これ = this
• が = subject marker
• 現実 = reality
• です = polite copula

So 現実です works like is reality in English.

Japanese often links nouns with です to make polite statements. So a noun can be the predicate very naturally.

It is often translated as is, but it is not exactly the same as the English verb to be in every situation.

Here, です functions as a polite copula. It makes the sentence polite and complete.

So:

• 現実です = is reality / it is reality

In casual speech, you might hear:

• これが現実だ

That has the same basic meaning, but it sounds less polite and more forceful.

Yes, sometimes, especially in casual speech or dramatic writing.

You may hear:

• これが現実だ
• これが現実

The first is casual/plain.
The second can sound blunt, dramatic, or like a caption or internal thought.

But for standard polite speech, これが現実です is the safest choice.

Japanese does not have articles like a, an, or the.

That means 現実 can be understood from context as:

• reality
• the reality
• a reality

In this sentence, English usually translates it naturally as This is reality or This is the reality, depending on context.

Japanese leaves that distinction to context rather than marking it with an article.

It is natural, but it often sounds strong or dramatic depending on context.

It can be used when someone wants to say something like:

• this is the truth
• this is how things really are
• this is the harsh reality

Because of the が, it often feels more pointed than a plain descriptive sentence.

So yes, it is natural, but it can carry emotional weight.

It is pronounced:

• kore ga genjitsu desu

A rough breakdown:

• こ = ko
• れ = re
• が = ga
• げん = gen
• じつ = jitsu
• で = de
• す = su

A few notes:

• In normal speech, です often sounds closer to des than a full desu
• じつ in 現実 is pronounced jitsu
• Japanese rhythm is more even than English rhythm

So the whole sentence is roughly:

• ko-re ga gen-ji-tsu des

No. Standard Japanese is normally written without spaces.

So the normal written form is:

これが現実です。

Spaces are often added only in learning materials to make the sentence easier to read.

Not exactly.

現実 means reality, not the adjective real.

So これが現実です is more like:

• This is reality.
• This is the reality.
• This is the real situation.

If you want This is real, Japanese would usually use a different structure, such as one built around 本物 or 本当, depending on the meaning.

Both are grammatical, but the nuance is different.

これが現実です

• focuses on this
• often sounds emphatic
• can feel like identifying something strongly

これは現実です

• presents this as the topic
• sounds more explanatory or neutral
• can feel slightly less dramatic

A simple way to remember it:

• が = this is the one
• は = as for this

In many situations, either can work, but が often gives a stronger punch.

Yes, Japanese often omits subjects and other information when they are clear from context.

For example, if everyone already knows what is being talked about, someone might just say:

• 現実です
• これが現実だ

But これ is included here because the speaker wants to point directly to something and identify it as reality. Including これ makes the statement clearer and often more forceful.
