akibin ha koko desu.

It is usually read あきびん.

• 空き = empty / emptied
• 瓶 = bottle

So 空き瓶 means empty bottle or empty bottles, depending on context.

You may also see it written as 空きビン, because 瓶 is a relatively uncommon kanji in everyday writing.

空き瓶 is a fixed compound noun, so the two parts are put together directly.

• 空き瓶 = empty bottle(s) as a category or label
• 空きの瓶 = a bottle that is empty

Both can be understood, but 空き瓶 is the more natural form for signs, labels, sorting categories, and general reference.

Normal Japanese usually does not use spaces between words.

So this would normally be written as:

空き瓶はここです。

The spaces are probably just there to help learners see the parts more clearly.

When は is used as the topic particle, it is pronounced わ, not は.

So:

• 空き瓶は = あきびんは, but pronounced あきびんわ

This is a standard feature of Japanese grammar and spelling. The particle keeps the written form は, even though the pronunciation is wa.

は marks the topic of the sentence.

So 空き瓶はここです means something like:

• As for empty bottles, this is the place
• Regarding empty bottles, here

In natural English, that often becomes Empty bottles go here.

A common beginner mistake is to think は always means the subject, but it is better to think of it as setting the topic or frame for what follows.

ここ means here, meaning a place near the speaker.

Related words:

• ここ = here
• そこ = there, near the listener
• あそこ = over there, away from both
• どこ = where

So ここ tells you the location being pointed out.

Japanese often leaves ideas implied when the context is clear.

This sentence uses the pattern:

A は B です

which is often translated as:

• A is B
• As for A, it is B

So literally, this is closer to As for empty bottles, it is here.

But in English, when talking about sorting or disposal, we naturally say Empty bottles go here. The verb is supplied by the context, not directly stated in the Japanese.

Because ここ is being used as the predicate in the pattern A は B です.

In other words:

• 空き瓶 = topic
• ここ = the location being identified
• です = polite copula

So ここ does not need に here.

You would use に if there were a verb that needed a location marker, for example:

• 空き瓶をここに入れてください。 = Please put empty bottles here.
• 空き瓶はここに置いてください。 = Please place empty bottles here.

です is the polite copula. It makes the sentence polite and complete.

It is often translated as is, but that is not always the best word-for-word match. Here it simply links the topic and the location in a polite way.

Compare:

• 空き瓶はここです。 = polite
• 空き瓶はここだ。 = plain / casual
• 空き瓶はここ。 = very casual, or sign-like

So です is doing more than just literally meaning is; it also sets the tone.

It can mean either. Japanese nouns usually do not show singular and plural the way English does.

So 空き瓶 could mean:

• an empty bottle
• empty bottles

The context tells you which is intended.

In a sign or recycling context, English usually uses the plural: Empty bottles go here.

Yes, it could, depending on the situation.

For example, if someone is looking for a specific empty bottle, and you point to it, 空き瓶はここです could mean The empty bottle is here.

But if this appears on a sign or near a recycling area, the intended meaning is more likely:

• Empty bottles go here
• This is where empty bottles go

So the exact English translation depends heavily on context.

Yes, it is understandable and natural in the right context, especially when someone is pointing out a location.

That said, in real-life signs or instructions, you might also see more direct versions such as:

• 空き瓶はこちら。 = Empty bottles this way / here
• 空き瓶はここに。 = Empty bottles here
• 空き瓶はここに入れてください。 = Please put empty bottles here

So 空き瓶はここです。 is fine, but other versions may sound more like signage or instructions depending on the situation.
