少々（しょうしょう） means a little, a bit, or for a short while. In this sentence, it means it will take a little time.

Compared with ちょっと, 少々 is more formal and is common in business Japanese. So:

• 少々時間がかかります = a polite/businesslike way to say it will take a little time
• ちょっと時間がかかります = more casual

It also softens the statement, so it sounds less blunt.

Because 時間がかかる is a fixed expression in Japanese meaning to take time.

In this pattern, 時間 is marked with が, not を:

• 時間がかかる = time is required / it takes time

This is different from English, where time looks more like an object in it takes time. In Japanese, the natural expression uses が.

Here, かかります is the polite form of かかる, and it means to take or to require, especially for time.

So:

• 時間がかかります = it takes time
• 少々時間がかかります = it will take a little time

This is a very common use of かかる.

Here, が connects two clauses and means something like but, though, or although.

• 少々時間がかかりますが、... = It will take a little time, but...

In polite Japanese, this kind of が often sounds softer than a strong but in English. It can introduce a mild contrast while keeping the tone courteous.

This is a very common question. Here, は marks 資料 as the topic:

• 資料は今日中に送信させていただきます = As for the materials, I will send them by the end of today

Using は can add a slight topic-setting or contrastive nuance, something like:

• As for the materials, I will send them today

If the speaker used を, it would sound more like a straightforward object:

• 資料を今日中に送信します = I will send the materials by the end of today

Both are possible, but 資料は feels natural in a business-style sentence, especially after the first clause about the delay.

今日中に（きょうじゅうに） means by the end of today or sometime before today is over.

So it gives a deadline:

• 今日中に送信します = I will send it by the end of today

The に marks the time limit or target point.

In business contexts, it usually means before today ends, though in real-life use people may sometimes interpret it according to the workday or business hours.

It is read きょうじゅう.

So:

• 今日中に = きょうじゅうに

This is important because 今日 is often read きょう, and 中 here is read じゅう, meaning within or during.

送信する specifically means to send electronically or to transmit, so it is often used for things like:

• emails
• files
• digital documents

Since 資料 often means documents or materials, 送信する sounds appropriate in a business setting, especially if the materials are being sent by email.

By contrast:

• 送る = a more general send
• 送信する = a more specific, formal send/transmit electronically

This is a very polite business expression. It breaks down like this:

• 送信する = to send
• させて = causative form (to let/allow someone to do)
• いただきます = humble form of receive

Literally, it is something like:

• I will humbly receive the favor of being allowed to send it

But in natural English, it usually just means:

• I will send it
• I will go ahead and send it

The expression adds politeness and humility. In business Japanese, this kind of phrasing is very common, even when no literal permission is being discussed.

Yes. 送信させていただきます is more polite, more formal, and more deferential than 送信します.

Compare:

• 送信します = polite and direct
• 送信させていただきます = more humble and businesslike

A native English speaker may feel that this sounds overly indirect, but in Japanese business communication, it is often used to sound respectful.

The subject is omitted because Japanese often leaves out information that is clear from context.

Here, the implied subject is something like:

• I
• we
• our side

So the full sense is something like:

• It will take a little time, but I/we will send the materials by the end of today.

Japanese does this very often, especially when the subject is obvious.

Yes, it is clearly formal and appropriate for business communication.

Some clues are:

• 少々 instead of ちょっと
• かかります in polite form
• 資料
• 送信
• させていただきます

A more casual version might be:

• ちょっと時間がかかりますが、資料は今日中に送ります。

That means basically the same thing, but it is much less formal.
