situkan wo kakuninsuru.

It is read:

しつかん を かくにんする

• 質感 = しつかん
• を = object marker, pronounced o
• 確認する = かくにんする

So the whole phrase is shitsukan o kakunin suru.

質感 refers to the texture, feel, or surface/material quality of something.

It is often used for things like:

• fabric
• paper
• wood
• leather
• product surfaces
• images or CG rendering

Depending on context, it can mean:

• how something feels to the touch
• how it appears visually as a material
• the overall sense of material quality

So it is broader than just physical texture in some cases.

を marks the direct object of the verb.

In this phrase:

• 質感 = the thing being checked
• 確認する = to confirm / check

So 質感を確認する literally means:

to check the texture / material feel

A helpful way to think about it:

• what are you confirming?
• 質感

That is why を is used.

確認する means to confirm, to check, or to verify.

The noun part is:

• 確認 = confirmation / checking / verification

By adding する, it becomes a verb:

• 確認する = to confirm / to check

This is very common in Japanese. Many Sino-Japanese nouns become verbs with する.

Examples:

• 勉強する = to study
• 説明する = to explain
• 確認する = to confirm

The dictionary form is often used in:

• headings
• labels
• instructions
• manuals
• notes
• bullet points
• neutral written statements

So 質感を確認する。 can sound like:

• a task item
• a step in a process
• a note in documentation
• a short plain-form statement

If you wanted to say it politely in conversation, you would usually say:

• 質感を確認します。

Yes. Japanese often omits the subject when it is obvious from context.

So 質感を確認する。 can still be a complete sentence, with an implied subject such as:

• I check the texture
• we check the texture
• you should check the texture
• one checks the texture

The exact subject depends on the situation.

It sounds natural in contexts like:

• product inspection
• design work
• manufacturing
• quality control
• photography or 3DCG
• shopping or choosing materials

For example:

• checking the feel of a fabric sample
• confirming the surface quality of a product
• reviewing whether a rendered object looks realistic
• examining packaging or printed materials

It is a fairly practical, work-like expression.

These words overlap, but they are not identical.

• 質感: material feel/quality; can be tactile or visual; somewhat broad and slightly formal
• 手触り: literally how something feels to the hand; strongly tactile
• テクスチャ: borrowed word texture; often used in art, design, graphics, and technical contexts

So:

• If you mean the actual feel when touching cloth, 手触り may fit well.
• If you mean overall material impression, 質感 is very natural.
• If you are talking about digital art or visual design, テクスチャ may be common.

It can mean either, depending on context.

質感 is not limited to touch. It can include:

• visual texture
• perceived material quality
• tactile feel

For example:

• looking at whether leather looks authentic
• touching a fabric sample
• evaluating the realism of a CG surface

If you want to emphasize actual touching, a different expression might be clearer, such as:

• 手触りを確認する

In very casual speech, particles are sometimes omitted, but here を is normally kept.

So the standard form is:

• 質感を確認する

Saying 質感確認する is generally not normal as a regular sentence.

However, in highly compressed note-taking, labels, or business shorthand, you might see reduced forms, but learners should treat 質感を確認する as the correct pattern.

Not exactly.

• 見る = to look / see / watch
• 確認する = to confirm / check / verify

確認する suggests checking carefully or intentionally, often to make sure something is correct or as expected.

So:

• 質感を見る = look at the texture
• 質感を確認する = check/confirm the texture

The second sounds more deliberate and goal-oriented.

Here are some common forms:

• plain present: 質感を確認する。
• polite present: 質感を確認します。
• plain past: 質感を確認した。
• polite past: 質感を確認しました。
• request: 質感を確認してください。
• let’s check: 質感を確認しましょう。

These are all built from 確認する.

It is moderately formal or neutral.

Reasons:

• 質感 is a somewhat technical or descriptive word
• 確認する is a common formal-neutral verb often used in business and practical situations

So it sounds more formal than something very casual like:

• 質感を見る
• 触って確かめる

But it is not extremely stiff. It is very normal in workplace, technical, design, and product-related contexts.
