okurisaki ga tooi mati de mo, kono kaisya nara hutuka de todoku sou desu.

送り先 means the destination for something being sent, such as a package or letter. Depending on context, it can mean:

• the shipping destination
• the delivery address
• the addressee

It is made from 送る (to send) + 先 (destination / the place ahead / recipient side).

Yes. 遠い directly modifies 町, so 遠い町 means a faraway town.

Then 送り先が marks the destination as the subject of that clause. So the whole part means something like:

even if the destination is a faraway town

or, more naturally in English,

even if it’s going to a distant town

It is not a relative clause like the town whose destination is far.

が marks 送り先 as the subject of the clause.

The speaker is essentially saying:

The destination is a faraway town, but even so...

In Japanese, が is very common when you are identifying what the subject of a smaller clause is. Here, 送り先 is the thing being described as 遠い町.

If you used は instead, the nuance would shift more toward making 送り先 the broader topic, which is not as natural here.

Yes. Here でも gives an even if / even ... nuance.

After a noun, でも can work like a softer everyday version of であっても, so:

• 町でも = even if it is a town / even if it’s a town like that
• 遠い町でも = even if it is a faraway town

So 送り先が遠い町でも means even if the destination is a distant town.

This is not the same as the location particle で meaning at or in.

この会社なら means something like:

• if it’s this company
• when it comes to this company
• with this company

The particle なら sets up a condition or standard. It often suggests contrast, such as:

Other companies might not do this, but this company can.

So the sentence has the nuance:

Even for a faraway destination, if you use this company, it apparently arrives in two days.

If you said この会社は, it would sound more like a plain statement about the company, and less like if you use this company.

二日で means in two days.

Here, で marks the amount of time needed to complete something. So:

• 二日で届く = it arrives in two days
• more literally, it takes two days for it to arrive

This is different from other time expressions:

• 二日に = on the second day or on the 2nd
• 二日間 = for two days

So 二日で is about the time required for the result to happen.

Because 届く means to arrive / to be delivered, while 届ける means to deliver something.

• 届く = intransitive
• 届ける = transitive

In this sentence, the focus is on the package arriving at the destination, not on someone delivering it as a direct object.

So:

• 荷物が届く = the package arrives
• 会社が荷物を届ける = the company delivers the package

The subject is omitted, which is very normal in Japanese.

What is understood is something like:

• the package
• the item
• the shipment

So the full idea is:

Even if the destination is a faraway town, with this company, the package apparently arrives in two days.

Japanese often leaves out words like it, the package, or the shipment when they are obvious from context.

Here it is hearsay.

Because そうです follows the plain dictionary form 届く, it means:

• I hear that it arrives
• they say it arrives
• apparently it arrives

So:

届くそうです = apparently it arrives / I hear it arrives

This is different from the looks like pattern:

• 届くそうです = hearsay
• 届きそうです = looks likely to arrive

That difference is very important.

Because the sentence is built around the noun phrase 遠い町 (a faraway town).

• 遠い町でも = even if it is a faraway town
• 遠くても = even if it is far

Both can be natural, but they are slightly different in structure.

The version in your sentence describes the destination as a distant town.
A version with 遠くても would focus more directly on the condition being far away.

In this context, この会社 most naturally sounds like the shipping company / delivery company / courier service.

That is because the sentence talks about how quickly something 届く (arrives). So the company is probably the service being used to send the item.

In natural English, you might translate the nuance as:

Even if the destination is a faraway town, this company can get it there in two days, apparently.
