eki no mawari ni mise ga takusan arimasu.

It is read:

えき の まわり に みせ が たくさん あります。

Word by word:

• 駅（えき） = station
• 周り（まわり） = surroundings / area around
• 店（みせ） = shop / store
• あります = there is / there are

A very literal breakdown is:

• 駅 = station
• の = of
• 周り = surrounding area
• に = in / at
• 店 = shops
• が = subject marker
• たくさん = many / a lot
• あります = exist / there are

So the structure is basically:

At the area around the station, shops exist in large numbers.

More natural English: There are many shops around the station.

駅の周り means the area around the station or around the station.

• 駅 = station
• の links it to 周り
• 周り literally means surroundings or the area around something

So 駅の周り is not just the station's surrounding in a possessive English sense; it means the vicinity of the station.

の connects nouns.

In 駅の周り:

• 駅 = station
• 周り = surroundings / around-area

So の makes station + surrounding area into one noun phrase: the area around the station.

This is a very common use of の. It often corresponds to English of, 's, or sometimes just a descriptive connection between nouns.

The に marks the location where something exists.

With あります and います, the place where something is located is usually marked by に.

So:

• 駅の周りに = around the station
• 店があります = there are shops

Put together: Around the station, there are shops.

This is a very common question.

• に marks a place where something exists
• で marks a place where an action happens

Since あります means to exist / there is / there are, Japanese uses に.

Compare:

• 駅の周りに店があります。
  = There are shops around the station.

• 駅の周りで買い物をします。
  = I shop around the station.

In the second sentence, 買い物をします is an action, so で is used.

In this sentence, が is the normal choice because it marks the thing that exists.

Pattern: [place] に [thing] が あります

So:

• 駅の周りに
• 店が
• たくさんあります

This is the standard there is / there are pattern.

If you said 店は, it would sound more like you are making shops the topic, often with some contrast or comparison:

• 駅の周りには店はたくさんあります。

This could suggest something like: There are plenty of shops around the station, but...

So for a simple neutral statement, が is more natural.

Here, たくさん functions adverbially, describing the verb あります.

So:

• 店がたくさんあります
  = There are many shops.

It is like saying: Shops exist plentifully.

Japanese often uses quantity words this way.

You can also say:

• たくさんの店があります。

That means: There are many shops too.

The difference is:

• 店がたくさんあります = focuses on the existence of shops in large numbers
• たくさんの店があります = many shops directly modifies 店

Both are natural.

Because 店 is not a living/animate being.

Japanese generally uses:

• あります for inanimate things
  Examples: buildings, shops, books, cars
• います for animate beings
  Examples: people, animals

So:

• 店があります = There is a shop / There are shops
• 人がいます = There are people

By itself, 店 can mean shop or shops. Japanese nouns usually do not change form for singular and plural the way English nouns do.

Here, たくさん tells you it is plural in meaning:

• 店 = shop(s)
• たくさん = many

So the sentence clearly means: There are many shops around the station.

Because Japanese is usually a verb-final language.

In many basic sentences, the verb comes last.

So instead of English order:

There are many shops around the station

Japanese does something more like:

Around the station, shops many exist

That is why あります comes at the end.

This is completely normal in Japanese grammar.

Yes, 駅の周り is very natural.

It emphasizes the surrounding area of the station.

A similar expression is:

• 駅の近く = near the station

So:

• 駅の周りに店がたくさんあります。
  = There are many shops around the station.
• 駅の近くに店がたくさんあります。
  = There are many shops near the station.

The difference is small, but:

• 周り suggests the general surrounding area
• 近く focuses more on nearness

Yes. That is a very close literal translation.

• 店が = shops
• たくさんあります = exist in large numbers
• 駅の周りに = around the station

But in natural English, we usually say:

There are many shops around the station.

So the literal translation is useful for understanding the grammar, while the natural translation is better English.
