間接照明 means indirect lighting.

The particle で is used to show the condition, means, or setting under which something happens. In this sentence, it means something like:

• under indirect lighting
• with indirect lighting
• in indirect light

So 間接照明で gives the context in which the wood grain looks beautiful.

木目（もくめ） means wood grain—the natural pattern in wood.

It does not mean just wood in general. It specifically refers to the lines, texture, and visual pattern you see on the surface of wood.

が marks 木目 as the thing that appears/looks beautiful.

With 見える, the thing that is visible or appears in some way is often marked with が:

• 木目が見える = The wood grain is visible.
• 木目が美しく見える = The wood grain looks beautiful.

If you used は, it would sound more like you are setting wood grain up as the topic for contrast or discussion:

• 木目は美しく見える = As for the wood grain, it looks beautiful.

In this sentence, が is the more natural neutral choice.

美しい is an i-adjective, and here it needs to modify the verb 見える.

When an i-adjective is used adverbially (to describe how something appears, happens, etc.), you change -い to -く:

• 美しい → 美しく

So:

• 美しく見える = looks beautiful / appears beautifully

This is a very common pattern:

• 早い → 早く
• 明るい → 明るく
• 美しい → 美しく

This is an important distinction.

• 見る = to look at / to watch / to see intentionally
• 見える = to be visible / to look / to appear

In this sentence, 見える is used because the meaning is about how the wood grain appears to the eye, not about someone actively looking at it.

So:

• 木目が美しく見える = The wood grain looks beautiful.
• It is not “someone sees the wood grain beautifully.”

In natural English, it means looks beautiful.

Literally, 美しく見える is something like appears beautifully, but in English we normally say:

• The wood grain looks beautiful.

So the phrase describes the appearance of the wood grain, not the manner of someone seeing it.

Yes, Japanese often leaves out information that is understood from context.

The sentence focuses on 木目 as the thing being described:

• 間接照明で、木目が美しく見える。
• Under indirect lighting, the wood grain looks beautiful.

Depending on context, English might add something like:

• In this room, the wood grain looks beautiful under indirect lighting.
• With indirect lighting, the wood grain looks beautiful.

But in Japanese, those extra elements are often omitted if they are already clear.

Grammatically, you could make a very literal translation like that, but it sounds unnatural in English.

A better translation is:

• The wood grain looks beautiful in indirect lighting.
• Under indirect lighting, the wood grain appears beautiful.

This is because 見える often corresponds to English looks when describing appearance.

The comma is mainly there to create a pause and make the sentence easier to read.

Japanese commas are often used more freely than English commas. Here it separates the setting phrase:

• 間接照明で、 = Under indirect lighting,
• 木目が美しく見える。 = the wood grain looks beautiful.

The sentence could also be written without the comma:

• 間接照明で木目が美しく見える。

That would still be correct.

Some natural translations are:

• The wood grain looks beautiful in indirect lighting.
• Under indirect lighting, the wood grain looks beautiful.
• Indirect lighting makes the wood grain look beautiful.

The last version is slightly less literal, but very natural if you want to express the effect of the lighting.

Yes, absolutely. It is a complete and natural Japanese sentence.

Japanese often omits subjects and other information that English usually states explicitly. As long as the main idea is clear, a sentence like this is perfectly normal:

• 間接照明で = under indirect lighting
• 木目が = the wood grain
• 美しく見える = looks beautiful

That is enough to form a complete thought.

Yes, to some extent.

見える often describes how something appears visually, so it can carry a nuance like:

• looks
• appears
• seems (visually)

So 木目が美しく見える does not necessarily claim an absolute fact like the wood grain is beautiful. It emphasizes how it appears to the eye, especially under the condition of indirect lighting.

That nuance is one reason 見える is a good choice here.
