sinsei no tezyun ha kousikisaito de kakunindekimasu.

It is read:

しんせい の てじゅん は こうしきサイト で かくにんできます。

Word by word:

• 申請 = しんせい = application
• 手順 = てじゅん = procedure / steps
• 公式サイト = こうしきサイト = official website
• 確認できます = かくにんできます = can check / can confirm

Here, の links two nouns together.

• 申請 = application
• 手順 = procedure / steps
• 申請の手順 = the application procedure or the steps for applying

A very common way to think of A の B is:

• B of A
• B for A
• A’s B

So 申請の手順 is not literally only procedure of application in stiff English; it naturally means the procedure for the application or the application steps.

は marks the topic of the sentence.

So:

• 申請の手順は = As for the application procedure, ...

The sentence is talking about the application procedure and then saying something about it: that it can be checked on the official website.

In English, we do not usually translate は directly. It often just sets up what the sentence is about.

So the structure is roughly:

• 申請の手順は = As for the application procedure,
• 公式サイトで確認できます = you can check it on the official website.

Because 申請の手順 is being treated as the topic with は, not simply as a direct object with を.

Japanese often does this:

• X は Y です
• X は Vできます

Here, 申請の手順 is the thing being discussed, so は is natural.

You could also say:

• 申請の手順を公式サイトで確認できます。

That version is also grammatical, and it focuses a bit more directly on the action checking the procedure.

The version with は feels a little more like:

• As for the application procedure, it can be checked on the official website.

This is very common in informational or 안내-style Japanese.

Here, で marks the place where an action happens.

So:

• 公式サイトで確認できます = can check it on the official website

Even though an official website is not a physical place in the same way as a room or store, Japanese often uses で for the place/platform where you do something.

Compare:

• 学校で勉強します = study at school
• 図書館で調べます = look it up at the library
• サイトで確認します = check it on the website

So this で is best understood as at/on the official website.

Because 確認する is an action, and で marks the location or setting where that action is performed.

• で = where an action takes place
• に = destination, existence, time, or target depending on context

Since checking happens on the official website, で is the natural choice.

If you used に, it would sound unnatural here.

So:

• 公式サイトで確認できます = correct
• 公式サイトに確認できます = unnatural

A simple rule of thumb: If you are doing something somewhere, で is often the particle you want.

確認できます is the polite potential form of 確認する.

Breakdown:

• 確認する = to check / to confirm
• 確認できる = can check / can confirm
• 確認できます = polite form of can check / can confirm

So this sentence is not just saying check or confirm. It is saying that checking is possible or available.

In natural English here, 確認できます often means:

• You can check
• It can be checked
• It is possible to check

Depending on the context, all of those are reasonable translations.

Great question. 確認 is a noun, but it also forms a suru-verb:

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

Once it becomes a suru-verb, it can make a potential form just like other verbs:

• 確認する → 確認できる

This pattern is very common:

• 利用する → 利用できる = can use
• 予約する → 予約できる = can reserve
• 説明する → 説明できる = can explain

So 確認できます is a very standard form.

Japanese often leaves out the subject when it is obvious from context or not important.

So 公式サイトで確認できます does not explicitly say:

• you can check
• we can check
• one can check
• it can be checked

The sentence just presents the information in a neutral way.

In English, we usually need to choose a subject, so translators often use:

• You can check the application procedure on the official website.

But the Japanese itself is more impersonal and informational.

Both are possible because 確認する can mean both to check and to confirm.

In this sentence, check is the more natural English choice:

• You can check the application procedure on the official website.

If you say confirm, it is not wrong, but it may sound slightly more formal or slightly less natural in everyday English for this context.

So:

• 確認する = check / confirm
• here, check is usually the best translation

Yes, it is polite and appropriate for official information.

Reasons:

• It uses the polite form できます
• It uses formal vocabulary like 申請, 手順, and 確認
• The overall style is common in notices, websites, instructions, and customer guidance

It is not extremely stiff or ceremonial, but it is definitely more formal than casual conversation.

Yes. A casual version would be:

• 申請の手順は公式サイトで確認できる。

That changes できます to the plain form できる.

The meaning stays the same, but the tone becomes less polite.

In everyday conversation, someone might also say:

• 申請の手順は公式サイトで見られるよ。
• 公式サイトを見れば、申請の手順がわかるよ。

Those are not exact copies of the original sentence, but they express a similar idea in a more conversational way.

Because サイト is a loanword from English site, so it is normally written in katakana.

• 公式 = a native/Sino-Japanese word, so kanji is normal
• サイト = borrowed word, so katakana is normal

This kind of mix is very common in modern Japanese:

• 公式サイト = official website
• オンライン申請 = online application
• サポート窓口 = support desk

So 公式サイト is a completely natural spelling.

A simple way to see it is:

[Topic] は [Place] で [Potential verb]

In this sentence:

• 申請の手順 = topic
• は = topic marker
• 公式サイト = place/platform
• で = place of action
• 確認できます = can check

So the sentence works like:

• As for the application procedure, it can be checked on the official website.

That is a very useful pattern to remember for reading announcements and instructions.
