kore ha hunengomi desu.

It is pronounced:

これ は ふねんごみ です。
Kore wa funen gomi desu.

A natural English-friendly pronunciation guide would be:

• ko-re wa
• fu-nen go-mi
• de-su

A couple of notes:

• The particle は is pronounced wa here, not ha.
• In natural speech, です often sounds closer to des because the u is very light or almost silent.

This is one of the first things learners notice.

When は is used as the topic particle, its pronunciation is wa.
So in this sentence:

• written: これは不燃ごみです。
• pronounced: kore wa funen gomi desu

But when は is part of a normal word, it is usually pronounced ha.

So here, は is not functioning as part of a word. It is a grammar marker.

は marks the topic of the sentence.

So これは不燃ごみです。 is literally something like:

• As for this, it is non-burnable garbage.

More natural English would be:

• This is non-burnable garbage.

The topic is これ meaning this, and the sentence says what that thing is.

The spaces are usually added for learners.

Normal Japanese is typically written without spaces:

これは不燃ごみです。

Textbooks, beginner materials, and language apps sometimes insert spaces to make the parts easier to see:

• これ
• は
• 不燃ごみ
• です

So the spaced version is helpful for study, but it is not the normal way Japanese is written.

It is read:

ふねんごみ
funen gomi

It breaks down like this:

• 不燃 = non-burnable
• ごみ = garbage / trash

So literally it means:

• non-burnable garbage
• non-burnable trash

This is a very common category in Japanese garbage sorting.

Because that is very common in everyday Japanese.

The word gomi can be written in different ways, such as:

• ごみ
• ゴミ
• sometimes kanji, though that is much less common in ordinary use

In daily writing, ごみ in hiragana or ゴミ in katakana is much more natural than using obscure kanji.

So 不燃ごみ is a very normal spelling.

です is the polite copula. In a sentence like this, it works like is / am / are in English, though it does not match English exactly.

So:

• これは不燃ごみです。
• This is non-burnable garbage.

It also makes the sentence polite and neutral.

A less polite or plain version would be:

• これは不燃ごみだ。

Beginners usually learn です first because it is appropriate in many everyday situations.

Yes, but the nuance changes.

• これは不燃ごみです。 = As for this, it is non-burnable garbage.
• これが不燃ごみです。 = This is the non-burnable garbage. / This is what counts as non-burnable garbage.

Using が often gives more focus or identification. It can sound like you are distinguishing this item from other items.

So if you are simply labeling or stating what something is, は is very natural.
If you are pointing out the correct item among several choices, が may fit better.

This is a very common beginner question.

• これ = this by itself
• この = this before a noun

So:

• これは不燃ごみです。 = This is non-burnable garbage.
• このごみは不燃です。 = This garbage is non-burnable.

You cannot say このです because この must be followed by a noun.

So in your sentence, これ is correct because it stands alone.

Yes, especially in contexts like:

• sorting trash
• explaining disposal rules
• pointing at an object and identifying which trash category it belongs to
• labels or instructions

For example, someone might hold up an item and say:

• これは不燃ごみです。

Meaning:

• This goes in the non-burnable trash.

In real life, Japanese people may also use shorter expressions depending on context, such as just:

• 不燃ごみです。
• 不燃ごみ。

Usually, no.

これ is used for things, not people. Using it for a person sounds rude because it treats the person like an object.

So this sentence is natural only if これ refers to an object.

If you want to refer to a person near you, you would say something like:

• この人 = this person

Because Japanese often leaves out information that is already clear from the situation.

If you are holding an object or pointing at it, これ already gives enough information. Japanese does not always spell everything out the way English does.

That is why a short sentence like:

• これは不燃ごみです。

can be complete and natural on its own when the context is obvious.
