kono hagaki no ura ni, kyouto de totta syasin ga insatusite arimasu.

Because に marks the place where something exists or is located.

Here, このはがきの裏に means on the back of this postcard or more literally at the back side of this postcard.

The second half of the sentence is talking about a photo being there in a printed state, so に is the natural particle.

• 裏に = on the back / at the back side
• not 裏で, because で would mark the place where an action happens

So:

• 京都で撮った = taken in Kyoto (place of action)
• はがきの裏に = on the postcard’s back (place where the result exists)

Because で marks the location where an action happens.

The verb 撮る means to take a photo, so 京都で撮った means took in Kyoto / taken in Kyoto.

Use で for the place of the action:

• 京都で撮る = take a photo in Kyoto
• 公園で食べる = eat in the park
• 部屋で勉強する = study in the room

Using に here would sound wrong, because に is not normally used for the location where you take a photo.

Because 撮った is modifying 写真.

In Japanese, when a verb comes before a noun, it describes that noun. So:

• 京都で撮った写真 = the photo that was taken in Kyoto

The photo was taken earlier, so 撮る becomes 撮った.

This does not make the whole sentence past tense. It only tells you that the action of taking the photo happened before the current situation.

Compare:

• 京都で撮る写真 = a photo that someone takes in Kyoto / will take in Kyoto
• 京都で撮った写真 = a photo that someone took in Kyoto

It is a relative clause: a clause placed directly before a noun to describe it.

Japanese does not need words like that, which, or who here.

So instead of saying:

• a photo that was taken in Kyoto

Japanese simply says:

• 京都で撮った写真

Breakdown:

• 京都で = in Kyoto
• 撮った = took / was taken
• 写真 = photo

Literally, it is something like:

• Kyoto-in took photo

but in natural English it becomes:

• a photo taken in Kyoto
• a photo that was taken in Kyoto

The person who took the photo is omitted because Japanese often leaves that understood.

Because this sentence uses the 〜てある pattern, and in that pattern the thing left in a certain state is often marked with が.

So:

• 写真が印刷してあります means something like the photo has been printed and is there in that state

This pattern focuses on the resulting state, not just the action itself.

Compare the idea:

• 印刷する = to print
• 印刷してある = to have printed / to be left printed

With 〜てある, the thing affected by the action often appears with が because it is now treated as the thing that exists in a prepared state.

So this sentence is not simply saying someone prints a photo. It is saying a photo has been printed there.

It is the 〜てある form of 印刷する.

Breakdown:

• 印刷する = to print
• 印刷してある = to be printed and left that way as the result of someone’s action
• 印刷してあります = polite form

This pattern is used when:

1. someone intentionally does something, and
2. the result of that action remains

So 写真が印刷してあります means more than just a photo is printed. It suggests:

• someone printed it intentionally
• the printed result is now there

That nuance is very common with 〜てある.

This is a very common question.

印刷してあります

• uses 〜てある
• emphasizes the result of an intentional action
• suggests someone printed it and left it that way

印刷されています

• is passive / state-like
• simply says it is printed
• does not emphasize the intentional preparation as much

In this sentence, 印刷してあります feels natural because a postcard is something that has been deliberately prepared with a photo printed on it.

So the nuance is roughly:

• 印刷してあります = it has been printed there on purpose
• 印刷されています = it is printed there

Both can be understandable in many situations, but 〜てある is especially good when talking about a visible result created intentionally.

Because Japanese often omits the subject or agent when it is not important or is already understood.

In this sentence:

• someone took the photo in Kyoto
• someone printed it on the back of the postcard

But the sentence does not need to say who. The focus is on the postcard and what is on it.

This is very normal in Japanese. English often wants an explicit subject, but Japanese frequently leaves it out if the meaning is clear enough from context.

この modifies はがき.

So:

• このはがき = this postcard

Then:

• このはがきの裏 = the back of this postcard

A good way to see the structure is:

• この → はがき
• このはがき → の裏
• このはがきの裏に → location phrase

So the sentence starts by setting the location:

• On the back of this postcard, ...

Here it specifically means the reverse side or back side of the postcard.

For a postcard, 裏 is the side opposite the front.

So:

• はがきの表 = the front of the postcard
• はがきの裏 = the back of the postcard

In this sentence, it means the photo is printed on the reverse side of the postcard, not just vaguely behind it.

No, normal Japanese is usually written without spaces.

A natural written version would be:

このはがきの裏に、京都で撮った写真が印刷してあります。

The spaces in your sentence are probably there for learners, to make the parts easier to read.

So the spaced version is a teaching aid, not standard everyday formatting.
