feriitaaminaru de zyousentetuduki wo suru.

で marks the place where an action happens.

So in フェリーターミナルで乗船手続きをする, フェリーターミナルで means at the ferry terminal or in the ferry terminal.

A useful comparison:

• で = where an action takes place
• に = destination, existence, or a specific point in time

Here, checking in is an action done at a location, so で is the natural choice.

を marks the direct object of the verb.

In this sentence, the thing being done is 乗船手続き:

• 乗船 = boarding
• 手続き = procedure, formalities

So 乗船手続きをする literally means to do the boarding procedures.

This is a very common pattern in Japanese:

• 勉強をする = to study
• 仕事をする = to do work
• 予約をする = to make a reservation
• 手続きをする = to do the necessary procedures

乗船手続き is a compound noun meaning boarding procedures or check-in for boarding.

It breaks down like this:

• 乗船 = boarding a ship or ferry
• 手続き = procedure, paperwork, formal process

So this refers to the process you go through before getting on the ferry, such as:

• checking in
• showing your ticket
• confirming your booking
• receiving boarding information

Japanese often uses する with nouns to create a verb phrase.

So instead of having one single verb meaning to complete boarding procedures, Japanese naturally says:

• 乗船手続きをする = to do the boarding procedures

This is extremely common and natural. Many actions in Japanese are expressed as:

noun + をする

Even though する by itself means to do, in combinations like this it works almost like part of the whole expression.

No subject is explicitly stated, and that is very normal in Japanese.

The sentence just says:

• At the ferry terminal, do the boarding procedure(s).

Depending on context, the understood subject could be:

• you
• we
• passengers
• one

Japanese often omits subjects when they are obvious from context. So this could appear in:

• instructions
• travel guides
• signs
• itinerary notes

It can function as a complete sentence, but it often sounds like a plain-form description, an instruction, or a step in a sequence.

Because it ends in plain する rather than polite します, it may sound like:

• a dictionary-style statement
• a written instruction
• a checklist item
• a heading in a travel guide or manual

For example, in a travel schedule, this kind of sentence is very natural.

If you wanted a polite spoken sentence, you might say:

• フェリーターミナルで乗船手続きをします。

No. Japanese is normally written without spaces.

So the standard writing would be:

フェリーターミナルで乗船手続きをする。

Spaces are sometimes added in learning materials to make the structure easier to see, but they are not normally used in regular Japanese writing.

A simple pronunciation guide is:

ferii taaminaru de jousen tetsuzuki o suru

A bit more closely:

• フェリーターミナル = fe-rī tā-mi-na-ru
• で = de
• 乗船手続き = jō-sen te-tsu-zu-ki
• を = pronounced o
• する = su-ru

Notes:

• The long vowels matter:
  • フェリー has a long ii
  • ターミナル has a long taa
  • 乗船 has a long jō
• The particle を is written wo in kana, but in modern Japanese it is pronounced o.

Because it is a loanword based on foreign-origin vocabulary.

• フェリー = ferry
• ターミナル = terminal

Katakana is commonly used for:

• foreign loanwords
• some onomatopoeia
• emphasis
• technical terms

So フェリーターミナル is exactly the kind of word you would expect to see in katakana.

Japanese nouns usually do not show singular vs. plural the way English nouns do.

So 乗船手続き could be understood in English as:

• the boarding procedure
• boarding procedures
• check-in procedures

The best English translation depends on context. Japanese leaves that number distinction unstated unless it really needs to be made clear.

The difference is mainly style and politeness.

• する = plain form
• します = polite form

So:

• フェリーターミナルで乗船手続きをする。
  plain / dictionary style / written note style

• フェリーターミナルで乗船手続きをします。
  polite spoken or written style

The core meaning is the same. The choice depends on context.

Yes. That is just the polite version.

Compare:

• 乗船手続きをする = to do the boarding procedures
• 乗船手続きをします = will do / do the boarding procedures (polite)

Both are natural. The sentence in your example uses the plain form, which often appears in textbooks, headings, schedules, and dictionary-style examples.

Yes, in natural English that is often the best way to express it.

Literally, the Japanese says do the boarding procedures at the ferry terminal, but in smoother English that could become:

• Check in at the ferry terminal.
• Complete boarding procedures at the ferry terminal.
• Go through boarding formalities at the ferry terminal.

So even if the meaning is already given, it is useful to know that the Japanese expression is a little more literal than the most natural English translation.
