この means this, but it must come before a noun.
So:
A useful comparison:
So you can say:
Here, で marks the context / means / place in which something is seen.
So この写真で means something like:
For an English speaker, this can feel a little surprising, because で is often first learned as a location marker for actions, like:
But で can also show the medium or setting through which something is perceived or understood. In this sentence, the photo is the visual context in which the brain is visible.
Because the verb is 見えます from 見える, not 見ます from 見る.
This is a very important difference:
With 見える, the thing that is visible is usually marked by が.
So:
Compare:
This is one of the most common questions.
見ます means to look at or to watch. It usually implies a deliberate action by a person.
Examples:
見えます means is visible, can be seen, or comes into view. It focuses on what is visible, not on the person doing the seeing.
Examples:
So in your sentence:
the idea is not someone is looking at the brain on purpose, but rather:
It can mean either, depending on context.
So 脳が見えます may be understood as:
Japanese often leaves the subject unstated, so English translations may vary.
In many cases, 見える is closer to be visible, but in natural English we often translate it as can see.
So for this sentence, both of these are reasonable:
Japanese often leaves out the subject when it is obvious or unimportant.
So this sentence does not explicitly say:
It simply says that the brain is visible in this photo.
Depending on context, English may supply a subject:
This is very normal in Japanese.
Yes, it is understandable and natural enough, especially in an explanatory context such as medicine, science, or image analysis.
It has the sense of:
That said, depending on context, Japanese speakers might also say things like:
There is a slight nuance difference:
So:
Your sentence is fine, especially if the point is what can be seen in the image.
Good question. Both で and に can appear with words related to pictures, but the nuance changes.
This emphasizes the photo as the means/context in which something is visible.
This is more natural with verbs like 写っている (to be shown/captured in a photo).
So に is not the best match with 見えます in this exact sentence. With 見えます, で works better for the intended meaning.
Because it ends with 見えます, which is the polite -ます form.
Polite form:
So this sentence is in standard polite Japanese, which is what learners usually study first.
A plain-style version would be:
That plain form might be used in casual speech, notes, or informal explanation, but 見えます is safer and more neutral in most learning contexts.
Yes. 写真 most often means:
So この写真 could be translated as:
The best English choice depends on context. For example:
The main thing is its reading and meaning:
The long vowel in のう matters. It is not a short no sound.
Also, 脳 is a somewhat formal/technical word compared with everyday body-part words like:
So this sentence sounds like something you might hear in:
The sentence breaks down like this:
So the basic pattern is:
[context] で [thing] が 見えます
This pattern is very useful. For example:
この地図で駅が見えます。
You can see the station on this map.
ここから海が見えます。
You can see the sea from here.
窓から山が見えます。
You can see the mountain from the window.
So your sentence follows a common and useful structure.
