その件 means that matter, that issue, or that case.

• その = that
• 件（けん） = matter, issue, case

In business Japanese, 件 is a very common formal word for referring to a topic, request, problem, or item under discussion.

は marks その件 as the topic of the sentence: as for that matter...

So the sentence is structured like:

• その件は = as for that matter
• 先に部署で確認させていただきます = we/I will first check it within the department

Using は gives a slightly more formal, organized feel than simply marking it as a direct object with を.

Because the sentence is not focusing on that matter as a direct object in a simple, neutral way. Instead, it sets up that matter as the topic.

Compare:

• その件は確認します = As for that matter, I’ll check it.
• その件を確認します = I’ll check that matter.

Both can be correct, but その件は sounds more like the speaker is taking up that topic and explaining what will happen about it. This is very common in business communication.

先に means first, before that, or ahead of time.

Here it suggests that checking with the department is the first step before some later action, such as:

• giving a final answer
• making a decision
• proceeding with a request

So the nuance is something like:

As for that matter, I’ll first check internally with the department.

部署で means something like in the department, within the department, or at the department level.

The particle で marks the place, setting, or context where an action happens.

So:

• 部署で確認する = check it within the department
• 部署に確認する = check with the department / ask the department to confirm

This is an important difference:

• で focuses on the action taking place inside that organizational context
• に would focus more on the department as the party being contacted

In this sentence, 部署で suggests internal checking within our department/team.

Grammatically, the speaker is the one presenting the action, but in practice it can mean:

• I will check
• We will check
• I will have it checked internally
• We will confirm it within the department

Japanese often leaves the subject unstated when it is understood from context. In business Japanese, this kind of wording can intentionally sound less personal and more organizational.

This is a polite business expression made from:

• 確認する = to confirm, check
• させていただく = to humbly do something / to be allowed to do something

So literally, it is something like:

I will humbly be allowed to confirm it.

But that is too literal for natural English. In real use, it usually just means:

• I’ll check
• I’ll confirm
• Let me confirm

with a very polite, humble tone.

Because 確認させていただきます is more polite and softer.

Compare:

• 確認します = I will confirm it.
  
  • polite, straightforward
• 確認させていただきます = I will check/confirm it, if I may / let me confirm it
  
  • more humble, more formal, common in customer service and business

This form often sounds more deferential toward the listener, especially a customer or someone outside the company.

However, learners should know that させていただく is sometimes overused in modern business Japanese. It is very common, but it can sound overly formal depending on context.

Originally, yes: させていただく has the idea of receiving the favor of being allowed to do something.

But in many real business situations, that literal sense of permission is weak or almost gone. It often functions mainly as a humble politeness formula.

So in this sentence, it does not necessarily mean someone explicitly gave permission. It is better understood as a polite way of saying:

• I’ll go ahead and confirm it
• Let me confirm it first

Japanese often builds meaning step by step:

• その件は = as for that matter
• 先に = first
• 部署で = within the department
• 確認させていただきます = I will politely confirm/check

So the sentence moves from:

1. topic
2. timing
3. context/location
4. main action

This is very normal Japanese structure. English usually puts the verb earlier, but Japanese saves the main verb until the end.

Usually yes, 部署 means department, division, section, or sometimes team/unit, depending on the company structure.

It is a formal organizational word. In this sentence, it gives a business-like tone and suggests that the matter needs to be checked internally rather than answered immediately on the spot.

Yes, it sounds very natural in business or customer-service settings.

The sentence gives several useful nuances at once:

• その件は: we are now talking about that issue
• 先に: there is a process, and this is the first step
• 部署で: it will be handled internally
• 確認させていただきます: the speaker is being polite and humble

A natural English equivalent might be:

• I’ll first check with my department regarding that matter.
• We’ll first confirm that internally.
• Let me check on that with the department first.

Yes. Depending on context, 確認 can mean:

• confirm
• check
• verify
• make sure
• look into

So in this sentence, translating it as confirm is not always the best choice in natural English. Often check or check internally sounds better.

For example:

• その件は先に部署で確認させていただきます
  • I’ll check with the department about that first.
  • We’ll verify that internally first.

The exact best translation depends on the situation.
