Here, で marks the place where the action happens.

So in この町で土地を買った, この町で means in this town or at this town in the sense of location of the buying.

A natural breakdown is:

• この町 = this town
• で = in/at (where the action takes place)
• 土地を = land
• 買った = bought

So the sentence means: (I/Someone) bought land in this town.

Because で is used for the location of an action, while に usually marks things like:

• a destination
• a specific point in time
• the location of existence with verbs like ある and いる
• an indirect target

Buying is an action, so the place where it happened is marked with で.

Compare:

• この町で土地を買った。 = Bought land in this town.
• この町に住んでいる。 = Live in this town.
• この町に行く。 = Go to this town.

So で is the correct particle here because the sentence is about where the buying took place.

を marks the direct object of the verb.

In this sentence, the thing being bought is 土地:

• 土地を買った = bought land

So 土地 is the object, and 買った is the action done to it.

買った is the plain past affirmative form of the verb 買う.

• dictionary form: 買う = to buy
• plain past: 買った = bought
• polite past: 買いました = bought

So this sentence is in a plain style, not a polite style.

Compare:

• この町で土地を買った。 = plain
• この町で土地を買いました。 = polite

Japanese often omits the subject when it is clear from context.

So この町で土地を買った could mean:

• I bought land in this town
• he bought land in this town
• she bought land in this town
• they bought land in this town

The exact subject depends on the situation.

This is very normal in Japanese. English usually requires a subject, but Japanese often leaves it out if the listener can infer it.

It modifies 町.

So:

• この町 = this town

The sentence is saying land in this town, not this land.

If you wanted to say this land, you would say:

• この土地

So the structure here is:

• この町で = in this town
• 土地を買った = bought land

Because この町で and 土地を買った are doing different jobs.

This is not one noun phrase like this town's land.
Instead, it is:

• この町で = in this town
• 土地を買った = bought land

So で connects この町 to the verb 買った as the location of the action.

If you said この町の土地, that would mean something more like:

• the land of this town
• land in this town as a noun phrase

For example:

• この町の土地は高い。 = Land in this town is expensive.

But in your sentence, the focus is on the action bought, so で is used.

土地 means land, a piece of land, or a plot of land.

It usually refers to land as real estate or property, not just dirt or soil.

So:

• 土地を買う = buy land / buy a plot of land

This is different from:

• 土 = soil, dirt
• 家 = house
• 庭 = garden/yard

So the sentence implies buying property land, not buying soil.

The basic word order is natural and standard:

• この町で = place
• 土地を = object
• 買った = verb

Japanese often puts the verb at the end.

So this is a very normal order: place + object + verb

Because particles show each word’s role, Japanese word order can sometimes be changed for emphasis, but the standard form here is the easiest and most natural for learners.

No, not naturally.

Because で marks the place where the action happened, the sentence means bought land in this town.

If you wanted to say from this town as a source, you would normally use a different structure, such as から in the appropriate context.

So this sentence is about location, not source.

Yes, in this sentence 町 is normally read まち.

So the full sentence is read:

この まち で とち を かった。

A natural pronunciation is:

• このまちで
• とちを
• かった

The spaces are usually just there to help learners read the sentence more easily.

Normally, Japanese is written without spaces:

この町で土地を買った。

So the spaced version is a teaching aid, not standard native writing.

Yes, it would sound unnatural in standard Japanese.

With 買う, the location where the buying happens is normally marked by で, not に.

So:

• この町で土地を買った。 = natural
• この町に土地を買った。 = unnatural

If に appears with 買う, it would usually be for a different grammatical role in a different sentence pattern, not for the location of the action here.
