kono kamera no syuuri ha zikan ga kakarimasu.

の links two nouns and shows a relationship between them. Here, このカメラの修理 means the repair of this camera or this camera’s repair.

So:

• このカメラ = this camera
• 修理 = repair
• このカメラの修理 = the repair of this camera

In English, we often use of or ’s. In Japanese, の does that job very often.

は marks the topic of the sentence: what the sentence is about.

In this sentence, the topic is:

このカメラの修理は = As for the repair of this camera...

Then the rest of the sentence says something about that topic:

時間がかかります = it takes time

So the overall structure is:

• Topic: this camera’s repair
• Comment about the topic: takes time

Japanese often uses this topic + comment structure.

This is a very common question. In this sentence, は and が are doing different jobs.

• は marks the overall topic: このカメラの修理
• が marks the thing connected directly to the verb かかります

With かかる in the sense of to take (time/money), the thing being taken is often marked with が:

• 時間がかかる = time is required / it takes time
• お金がかかる = money is required / it costs money

So the sentence is not strange to Japanese speakers. It is basically:

As for this camera’s repair, time is required.

That is why both particles appear.

Very literally, it is something like:

time takes / time is required

But in natural English, we usually translate it as:

• it takes time
• it will take time

The verb かかる has several meanings, but here it means to take (time, money, effort).

Examples:

• 時間がかかる = to take time
• お金がかかる = to cost money
• 手間がかかる = to take effort / to be troublesome

Because Japanese often leaves things general when the exact amount is unknown, unnecessary, or not being emphasized.

So 時間がかかります means:

• It will take time
• It may take a while

If you wanted to be specific, you could say something like:

• 一時間かかります = It takes one hour
• 三日ほどかかります = It will take about three days

Here, the speaker is just saying that the repair is not quick.

Here, 修理 is a noun meaning repair.

That is why it can be part of a noun phrase:

このカメラの修理 = the repair of this camera

But 修理 can also be used with する to make a verb:

• 修理する = to repair

So a related sentence could be:

このカメラを修理するのは時間がかかります。
= Repairing this camera takes time.

That version is more explicitly verbal. The original sentence is more noun-based and sounds very natural in practical situations like at a repair shop.

Because 修理 by itself is a noun, not a standalone verb.

• このカメラの修理 = the repair of this camera
• このカメラを修理する = to repair this camera

If you use を, you normally need a verb such as する:

• このカメラを修理します = I/they will repair this camera

But in the original sentence, the speaker is talking about the repair as a thing or topic, so の is used.

They are the same verb in different forms.

• かかる = plain form
• かかります = polite form

So:

• 時間がかかる = plain / casual
• 時間がかかります = polite

The sentence uses かかります because it sounds polite and is appropriate in many everyday situations, especially customer-service situations such as discussing repairs.

In most contexts, it means will take time or takes time in a general sense.

Japanese non-past forms like かかります can cover both present and future depending on context.

So this sentence could mean:

• This camera’s repair takes time
• Repairing this camera will take time

In a repair-shop context, the future meaning is especially likely: the repair is expected to take some time.

Yes, if the context is already clear.

• このカメラの修理は時間がかかります。 = The repair of this camera takes time.
• カメラの修理は時間がかかります。 = Camera repair takes time / The repair of a camera takes time.

Using この makes it specific: the speaker is talking about a particular camera.

Not exactly.

• 時間がかかります means it takes time
• 長くかかります means it takes a long time

So 長く is more explicit about the duration being long.

Compare:

• 時間がかかります = it will take time
• 長くかかります = it will take a long time

The original sentence can already imply that the repair will not be quick, but 長く makes that stronger and clearer.
