kyuuryou ga haitta node, yatin wo ginkou kara hurikomimasita.

Yes. In Japanese, 給料が入る is a very common way to say that your salary came in, was paid, or was deposited.

So 入る here does not mean someone physically walked in with the salary. It means money became available to you, usually by being deposited into your account.

• 給料が入る = salary comes in / payday arrives / salary is deposited

This is a natural Japanese expression, even though the English wording feels different.

が marks 給料 as the subject of 入った.

• 給料が入った = the salary came in

You cannot use を here because 入る is an intransitive verb, so it does not take a direct object.

Why not は? You could say 給料は入ったので in some contexts, but it gives a different nuance. が is more neutral and event-focused: the salary came in. は would make salary the topic, often with a contrastive or topical feeling, like as for the salary, it came in...

So in this sentence, が is the most straightforward choice.

This is a very common pattern in Japanese.

Even when the main sentence is polite, verbs inside subordinate clauses often stay in the plain form.

So:

• 給料が入ったので、... 振り込みました。

is completely normal.

The first verb, 入った, is inside the ので clause, so plain form is expected. The main verb, 振り込みました, carries the politeness for the whole sentence.

A very similar pattern is:

• 時間がなかったので、行きませんでした。
• 雨が降ったので、帰りました。

This is standard Japanese.

Here, ので means because or since.

• 給料が入ったので、家賃を銀行から振り込みました。
• Because my salary came in, I transferred the rent from the bank.

Compared with から, ので often sounds a little:

• softer
• more explanatory
• more objective

So:

• 給料が入ったから、家賃を銀行から振り込みました。 also works, but it can sound slightly more direct or conversational.

In many everyday situations, both are possible. ので just sounds a bit gentler and more formal/polite in tone.

Yes, 家賃 means rent, specifically the rent paid for a house, apartment, or room.

It is a noun:

• 家 = house/home
• 賃 = fee/charge

So 家賃を払う means to pay rent.

In this sentence, 家賃を振り込みました means the speaker paid the rent by bank transfer.

を marks the direct object of 振り込む.

• 家賃を振り込む = to transfer the rent

The verb 振り込む is a transitive verb when talking about transferring money, so the amount or payment being transferred is marked with を.

Compare:

• お金を振り込む = transfer money
• 家賃を振り込む = transfer the rent
• 授業料を振り込む = transfer the tuition

振り込みました is the polite past form of 振り込む, which means to transfer money, usually into someone’s bank account.

So it often implies:

• bank transfer
• wire transfer
• direct deposit/payment into an account

In this sentence, it means the speaker paid the rent by transferring the money.

It is more specific than simply 払いました.

• 払いました = paid
• 振り込みました = paid by bank transfer / transferred the money

から marks the starting point or source.

So 銀行から振り込みました suggests the transfer was made from the bank, or more naturally in English, through the bank or from my bank account.

The idea is that the money moved starting from the speaker’s bank side.

In natural usage, Japanese may leave out details like:

• which account it came from
• whose account received it

Those details are often understood from context.

Also, depending on context, learners may see expressions such as:

• 銀行で振り込みました = I made the transfer at the bank
• 口座から振り込みました = I transferred it from my account

So から focuses on the source, while で would focus more on the place or means.

Japanese often omits information that is obvious from context.

With 振り込む, the destination can be stated, but it does not have to be.

For example, a fuller sentence could be something like:

• 大家さんの口座に家賃を銀行から振り込みました。 = I transferred the rent from the bank to the landlord’s account.

In your sentence, the listener can easily understand that the rent was transferred to the proper recipient, so the destination is left out.

This kind of omission is very common in Japanese.

The subject is understood to be the speaker: I.

Japanese frequently drops subjects when they are clear from context. In a sentence like this, if someone says:

• 給料が入ったので、家賃を銀行から振り込みました。

it is naturally understood as:

• Because my salary came in, I transferred the rent from the bank.

Japanese usually avoids repeating 私は unless there is a reason to emphasize or contrast it.

Because both actions are being presented as completed:

• 給料が入った = the salary came in
• 振り込みました = I transferred the rent

The first completed event is the reason for the second completed event.

Japanese often uses the past in this kind of sequence:

1. something happened
2. because of that, something else was done

So the past tense here is very natural.

Yes, the nuance changes.

• 給料が入ったので = because the salary came in
• 給料が入るので = because the salary will come in / because the salary comes in

In your sentence, 入った shows that the salary has already arrived, and then the speaker paid the rent.

If you used 入るので, it would sound more like the salary is expected or scheduled to come in, and that expectation is the reason.

So 入ったので fits best for a completed payday situation.

The basic order is very natural:

• 給料が入ったので、家賃を銀行から振り込みました。

Japanese often puts the reason clause first, then the main action.

You can move some parts around, especially inside the main clause, because Japanese particles show each word’s role. For example, these are still understandable:

• 給料が入ったので、銀行から家賃を振り込みました。
• 家賃を、給料が入ったので、銀行から振り込みました。

But the original version sounds smoother and more standard.

So the order is not absolutely fixed, but the given sentence is the most natural everyday arrangement.

No. Normal Japanese writing usually does not include spaces like this.

The sentence would normally be written as:

給料が入ったので、家賃を銀行から振り込みました。

Spaces are often added in learning materials to help beginners see the parts more clearly, but they are not standard in regular Japanese text.
