ferii ha feriitaaminaru ni aru.

When は is used as the topic particle, it is pronounced wa, even though the character itself is normally read ha in other words.

So in:

フェリー は フェリーターミナル に ある。

the は is not part of a word. It is a grammar particle marking フェリー as the topic of the sentence.

は marks the topic: what the sentence is about.

So フェリーは means something like:

• As for the ferry...
• Speaking of the ferry...

The sentence then gives information about that topic: it is at the ferry terminal.

This is slightly different from a plain subject marker like が. は often feels more like setting the topic and then commenting on it.

に marks the location of existence with verbs like ある and いる.

In this sentence:

フェリーターミナル に ある

means:

• is at the ferry terminal
• exists at the ferry terminal

With ある and いる, に is the normal particle for the place where something exists.

Because で marks the place where an action happens, while に marks the place where something is.

Compare:

• フェリーターミナルにある。 = It is at the ferry terminal.
• フェリーターミナルで待つ。 = Wait at the ferry terminal.

Since ある means to exist / to be located, に is the correct particle.

Japanese usually uses:

• ある for inanimate things
• いる for animate beings like people and animals

A ferry is an object, so ある is used.

Examples:

• 船がある。 = There is a boat.
• 人がいる。 = There is a person.

Even though a ferry moves, it is still grammatically treated as a thing, not a living being.

The basic order is:

topic + place + verb

So:

• フェリーは = as for the ferry
• フェリーターミナルに = at the ferry terminal
• ある = is / exists

Japanese verbs normally come at the end of the sentence, so this is very typical Japanese word order.

Yes, you could say:

フェリーがフェリーターミナルにある。

But the nuance changes.

• は presents フェリー as the topic: As for the ferry, it is at the ferry terminal.
• が more directly marks フェリー as the subject and can sound more like introducing or identifying it: The ferry is at the ferry terminal or There is a ferry at the ferry terminal, depending on context.

In many situations both are possible, but は and が are not interchangeable in every context.

With は, it most naturally means:

• The ferry is at the ferry terminal
• As for the ferry, it is at the ferry terminal

If you wanted to emphasize simple existence more strongly, Japanese often uses が:

フェリーがフェリーターミナルにある。

So the version with は sounds more like the ferry is already known in the conversation.

Katakana is commonly used for:

• foreign loanwords
• foreign names
• some technical or modern terms
• emphasis in some cases

Both フェリー and ターミナル are loanwords from English:

• フェリー = ferry
• ターミナル = terminal

So katakana is exactly what you would expect here.

Yes. It is a natural katakana compound meaning ferry terminal.

Japanese often combines loanwords this way, especially for modern transport or business vocabulary.

You may also sometimes see expressions like:

• フェリー乗り場 = ferry boarding area / ferry stop
• 港 = port
• ターミナル = terminal

But フェリーターミナル is perfectly understandable and standard.

Japanese does not have articles like English a and the.

Whether フェリー means:

• a ferry
• the ferry

depends on context.

In this sentence, because は is used, it often feels like the ferry or that ferry already known to the listener. But Japanese does not mark that with a separate article the way English does.

Not only that. ある can mean several related things, such as:

• to exist
• to be located
• to have in some contexts

In this sentence, it means to be located:

• フェリーターミナルにある = is at the ferry terminal

So here it is not just abstract existence; it is physical location.

Yes. あります is the polite form of ある.

So:

• フェリーはフェリーターミナルにある。 = plain style
• フェリーはフェリーターミナルにあります。 = polite style

The meaning is the same, but あります is more appropriate in polite conversation, customer service, announcements, and many everyday situations with strangers.

Yes. Normal Japanese writing usually does not use spaces.

So the standard written form is:

フェリーはフェリーターミナルにある。

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

Yes, grammatically it is natural.

It means that the ferry is located at the ferry terminal. Depending on the real-world situation, a native speaker might also choose a different expression if they want to be more specific, such as talking about the ferry being docked, arriving, or departing. But as a basic location sentence, it is completely fine.
