It is pronounced:

じょうしゃ てきおう しんちょう を かくにんする

Breakdown:

• 乗車 = じょうしゃ
• 適応 = てきおう
• 身長 = しんちょう
• を = pronounced o
• 確認する = かくにんする

In normal writing, it would usually appear without spaces: 乗車適応身長を確認する。

を marks the direct object of the verb.

Here, the verb is 確認する (to check / confirm), and the thing being checked is 乗車適応身長. So the structure is:

[thing being checked] + を + 確認する

This is a very common pattern in Japanese:

• 名前を確認する = check the name
• 時間を確認する = check the time
• 条件を確認する = check the conditions

The dictionary form is often used in:

• manuals
• instructions
• labels
• checklist items
• signage

So 確認する。 can sound like:

• a written instruction
• a procedural step
• a brief note in a manual

It is less like natural spoken conversation and more like an item on a list.

For example:

• 乗車適応身長を確認する。 = a checklist-style instruction
• 乗車適応身長を確認してください。 = a direct polite request to someone
• 乗車適応身長を確認します。 = I/we will check the height requirement

This is a long noun compound, which is very common in Japanese.

It can be understood as:

• 乗車 = riding / boarding
• 適応 = suitability / applicability / adaptation
• 身長 = height

Together, they form one big noun: 乗車適応身長

Japanese often stacks nouns before another noun to specify it. The final noun is usually the main one, and the earlier parts describe it.

So here, 身長 is the core noun, and 乗車適応 narrows down what kind of height is being talked about.

It sounds technical or formal rather than everyday.

A native speaker would more likely encounter this kind of wording in:

• safety notices
• amusement park rules
• product instructions
• official guidance

In normal conversation, people might use a more natural phrasing depending on context, such as something closer to:

• 乗れる身長
• 乗車できる身長
• 身長制限

So yes, it is understandable, but it feels like written technical language rather than casual speech.

Japanese often leaves out the subject when it is obvious from context.

In a manual or instruction, the reader understands that this is something the staff member, the operator, or the reader should do. Because of that, Japanese does not need to say:

• あなたは
• 係員は
• スタッフは

English usually prefers an explicit subject or an imperative, but Japanese often relies on context.

Normally, Japanese is written without spaces:

乗車適応身長を確認する。

Spaces are sometimes added:

• for learners
• in teaching materials
• to make structure easier to see
• in some digital interfaces

So the spaces here are not standard native-style writing. They are just helping readability.

Yes. In Japanese, this is completely fine, especially in instruction-style writing.

The pattern is simply:

noun + を + verb

That is enough to make a complete sentence:

• チケットを見せる。
• 名前を確認する。
• ドアを閉める。

Japanese often allows very compact sentences, especially when the situation is already clear.

Yes. 確認する covers both ideas in many contexts.

Depending on the situation, it can mean:

• check
• confirm
• make sure of
• verify

In instructions, check is often the most natural English choice. In more formal or procedural contexts, confirm or verify may fit better.

確認する is a suru-verb.

That means:

• 確認 is a noun
• adding する turns it into a verb

So:

• 確認 = confirmation / checking
• 確認する = to confirm / to check

This is a very common pattern in Japanese:

• 勉強する = to study
• 連絡する = to contact
• 説明する = to explain

Yes. That would be very natural if you want to make it a polite instruction to the listener.

Compare:

• 乗車適応身長を確認する。 = checklist/manual style
• 乗車適応身長を確認してください。 = please check the height requirement

So the version with してください sounds more directly addressed to a person.

乗車 literally means boarding / riding a vehicle and is often used in formal language.

It can apply to:

• trains
• buses
• taxis
• other vehicles

In some contexts, especially formal notices or rules, it can also be used more broadly for riding something.

However, in amusement-park or attraction contexts, the most natural wording may depend on the exact situation. Japanese often uses different expressions depending on whether the thing is a vehicle, an attraction, or a machine.

Yes, if the context already makes it clear what kind of height you mean.

Japanese often drops extra detail when it is obvious. So:

• 身長を確認する = check the height

But if a document needs to be precise, it may use a longer compound like 乗車適応身長 to avoid ambiguity.
