asita eki no mae de tomodati to matiawase wo simasu.

Japanese often leaves out the topic or subject when it is obvious from context.

So instead of saying something like:

• 私は明日駅の前で友達と待ち合わせをします。

the sentence simply says:

• 明日 駅の前で 友達と 待ち合わせをします。

This is very natural. The unstated subject is usually I in a sentence like this, but it could also be we or another person if the context makes that clear.

Time words such as 今日, 明日, 昨日, 今, and 毎日 often appear without any particle.

So:

• 明日行きます。 = I’ll go tomorrow.
• 今日勉強します。 = I study today.

You can sometimes use に with certain time expressions, but with words like 明日, it is usually omitted.
So 明日 by itself naturally means tomorrow in the sentence.

It literally means the front of the station.

Breakdown:

• 駅 = station
• の = linking particle, similar to of
• 前 = front / in front / before

So 駅の前 means in front of the station or the area in front of the station.

This is a very common pattern in Japanese:

• 学校の前 = in front of the school
• 家の前 = in front of the house

で marks the place where an action happens.

Here, the action is 待ち合わせをします = meet up / arrange to meet.
That action happens at/in front of the station, so Japanese uses で.

Compare:

• 公園で話します。 = talk at the park
• 家で食べます。 = eat at home

So:

• 駅の前で = in front of the station as the location of the meeting

Here, と means with when talking about doing something together with someone.

So:

• 友達と待ち合わせをします。 = meet up with a friend

Other examples:

• 母と行きます。 = go with my mother
• 先生と話します。 = talk with the teacher

So in this sentence, 友達と shows the other person involved in the meeting.

待ち合わせ means an arranged meeting, meeting up, or rendezvous.

It comes from the verb 待ち合わせる, which means to meet someone at an agreed place/time.

In everyday Japanese, you will often see it as:

• 待ち合わせをする

This is a noun + する pattern, which turns a noun into a verb-like expression.

So:

• 待ち合わせをします = will meet up / will have a rendezvous / will meet by arrangement

It is not just wait. It specifically means meeting someone by prior arrangement.

Japanese often uses noun + をする to express actions.

Examples:

• 勉強をします = study
• 買い物をします = do shopping
• 約束をします = make a promise
• 待ち合わせをします = meet up by arrangement

There is also the verb 待ち合わせる, but 待ち合わせをする is very common and natural.

So this sentence is using a very standard Japanese pattern.

Because 待ち合わせ is being treated as a noun here, and を marks it as the thing being done with する.

Pattern:

• noun + を + する

So:

• 待ち合わせ = meeting-up / arranged meeting
• 待ち合わせをする = to do a meet-up / to meet up

Even though English would not say do a meeting-up, this structure is completely normal in Japanese.

In this sentence, 明日 is most naturally read as あした.

So the full sentence would be read:

• あした えき の まえ で ともだち と まちあわせ を します。

明日 can also be read みょうにち, but that reading is more formal or written-sounding.
In everyday conversation, あした is much more common.

It is read:

• まちあわせ

So:

• 待ち合わせをします
• まちあわせ を します

This is useful to remember because the kanji may look complicated at first, but the reading is straightforward once learned.

Japanese word order is more flexible than English, as long as the particles stay attached to the right words.

This sentence:

• 明日 駅の前で 友達と 待ち合わせをします。

could also be rearranged, for example:

• 明日 友達と 駅の前で 待ち合わせをします。

Both are natural. The basic idea is that the important grammatical relationships are shown by the particles:

• で = location of action
• と = with
• を = object of する

Usually, the verb goes at the end, but the other parts can move for emphasis or style.

します is the polite non-past form of する.

In this sentence, it can mean:

• do
• will do

Because Japanese non-past often covers both present and future, the time word 明日 tells you this sentence is about the future:

• 明日...します = will do ... tomorrow

So します here means something like will meet up in polite speech.

Not exactly. That would usually use the verb 待つ.

• 友達を駅の前で待ちます。 = I will wait for my friend in front of the station.

But your sentence uses:

• 友達と待ち合わせをします。

That means I will meet up with my friend, with the idea that both people have agreed to meet there.

So 待つ = wait
while 待ち合わせをする = meet up by arrangement

That is an important difference.
