受取人 means recipient or the person receiving the package.

The particle が marks it as the subject of the clause 受取人が昼間は家にいない.

So this part means: the recipient is not at home during the day

Here, が is just identifying who is the one not at home.

昼間は means as for the daytime or during the day with a slight contrastive feel.

The sentence is not just saying at daytime, but something closer to: during the day, at least, the recipient is not at home

That often implies a contrast such as:

• maybe they are home at night
• but during the day they are not home

If it were just 昼間に, it would sound more like a simple time marker. 昼間は highlights that time period as the relevant one.

With the verb いる (to be / to exist for animate beings), Japanese normally uses に to mark the location.

So:

• 家にいる = to be at home
• 家にいない = not to be at home

で is usually used for the place where an action happens, but いる is not treated as that kind of action here. It is about existence/location, so に is the natural particle.

Before ので, Japanese normally uses the plain form.

So:

• いないので = because ... is not there / not at home
• いませんので is also possible and more formally polite

In this sentence, the speaker uses:

• plain form in the reason clause: いないので
• polite form at the end: お願いしました

This mix is very common in Japanese. The final verb often carries the overall politeness level.

ので means because or since.

In this sentence: 受取人が昼間は家にいないので、再配達をお願いしました。 = Because the recipient is not at home during the day, I requested redelivery.

Compared with から, ので usually sounds:

• a bit softer
• more explanatory
• more neutral/polite

So ので fits well when giving a reason in a calm, matter-of-fact way.

It is omitted, which is very normal in Japanese.

From context, the subject is something like:

• I
• we
• the speaker

So the full idea is: Because the recipient is not at home during the day, I requested redelivery.

Japanese often leaves out subjects when they are obvious from context.

Literally, it is something like: I asked for redelivery

Breakdown:

• 再配達 = redelivery
• を = marks the thing being requested
• お願いしました = requested / asked for

In natural English, depending on context, it could be:

• I requested redelivery
• I asked for another delivery attempt

In this pattern, Xをお願いする means to request X or to ask for X.

So:

• 再配達をお願いしました = requested redelivery

This is a very common and useful pattern:

• 確認をお願いします = please confirm
• ご連絡をお願いします = please contact me / please get in touch
• 対応をお願いしました = I requested that they handle it

Even though お願いする comes from 願う (to wish/request), as a set phrase it often works like request X.

Japanese often uses the role or status of a person rather than a pronoun when that is more relevant.

Here, 受取人 focuses on the person as: the package recipient

That is useful because the sentence is about delivery logistics, not about the person’s identity in general.

So it sounds natural in a delivery-related context.

Yes. Besides simply meaning not at home during the day, it can imply:

• this is a habitual or usual situation
• daytime is the problem for delivery
• other times may be better

So it sounds like a practical explanation for why redelivery was needed.

Yes. It breaks neatly into:

1. 受取人が昼間は家にいないので = because the recipient is not at home during the day

2. 再配達をお願いしました = I requested redelivery

This is a very common Japanese sentence pattern: Reason + ので / から + main action

In a historical or literal sense, お願いする comes from polite/humble language around requesting, but in modern everyday Japanese it often just functions as a polite way to say:

• ask
• request
• ask for

So in this sentence, you usually should not over-translate it. The natural meaning is simply: I requested redelivery.

The comma marks the pause between the reason clause and the main clause.

So it helps show the structure:

• reason: 受取人が昼間は家にいないので
• result/action: 再配達をお願いしました

Japanese commas are often used more flexibly than English commas, but here it makes the sentence easier to read.
