syouhin wo konpousimasu.

It’s read:

• 商品 → しょうひん (shōhin)
• を → お (even though it is written を, in modern Japanese it is pronounced like お)
• 梱包します → こんぽうします (konpō shimasu)

So the whole sentence is:

しょうひん を こんぽうします。

を marks the direct object of the verb — in other words, the thing that the action is done to.

Here:

• 商品 = the item(s), merchandise, goods
• を = marks that item as the object
• 梱包します = pack / package

So 商品を means the goods/items as the thing being packed.

For an English speaker, you can think of を as showing what receives the action of the verb.

Because 梱包 is a noun meaning something like packing or packaging, and Japanese often makes verbs by combining a noun with する.

So:

• 梱包 = packing, packaging
• 梱包する = to pack, to package
• 梱包します = polite form of 梱包する

This pattern is very common in Japanese, especially with formal or technical words:

• 勉強する = to study
• 予約する = to reserve
• 確認する = to confirm
• 梱包する = to pack/package

します is the polite non-past form of する.

So:

• 梱包する = plain/dictionary form
• 梱包します = polite form

Japanese often uses ます forms in neutral polite speech, workplace speech, customer service, instructions, and general formal communication.

This sentence sounds natural in a business or work context because 梱包 itself is also a somewhat formal/business-like word.

The subject is omitted, which is very normal in Japanese.

Japanese often leaves out information that is understood from context. So 商品を梱包します。 could mean:

• I will pack the goods
• We pack the goods
• They pack the goods
• (Someone) packs the goods

The exact subject depends on the situation.

This is one of the most important differences from English: Japanese frequently drops subjects when they are obvious or not important.

Not exactly.

• 商品（しょうひん） = goods, merchandise, items for sale
• 製品（せいひん） = products, manufactured products

商品 focuses more on something as a commercial item being sold. 製品 focuses more on something as a product that has been made/manufactured.

In a shipping, sales, or warehouse context, 商品 is very natural.

They are related, but not identical.

• 包む（つつむ） = to wrap, to cover, to enclose
• 梱包する（こんぽうする） = to pack/package for shipping or handling

包む is a more general everyday verb.
梱包する is more specific and more formal, often used in logistics, business, warehouses, online selling, and shipping.

So:

• プレゼントを包む = wrap a present
• 商品を梱包する = package goods for shipment

Using 梱包する makes it sound more like proper packing work, not just wrapping something in paper.

Japanese nouns usually do not change for singular vs. plural.

So 商品 can mean:

• a product/item
• products/items/goods

You tell from context.

That means 商品を梱包します。 could refer to:

• packing one item
• packing several items
• packing merchandise in general

Japanese often leaves number unspecified unless it matters.

Yes, it is natural, especially in a work or business context.

It could be used in situations like:

• describing a job duty
• explaining a process
• answering What do you do next?
• writing a simple procedure
• speaking in a warehouse or shipping department

Because 梱包 is fairly formal, the sentence sounds especially suitable for business, logistics, or operations.

Yes.

That is the dictionary/plain form.

Compare:

• 商品を梱包します。 = polite
• 商品を梱包する。 = plain

The plain form might be used in:

• casual speech
• notes
• manuals
• titles
• internal documentation
• explanatory writing

For example, in a procedure list, you might see:

1. 商品を確認する。
2. 商品を梱包する。
3. 発送する。

Here are the common forms:

• 商品を梱包します。 = pack / will pack
• 商品を梱包しました。 = packed
• 商品を梱包しません。 = do not pack / will not pack
• 商品を梱包しませんでした。 = did not pack

Plain forms:

• 商品を梱包する = to pack
• 商品を梱包した = packed
• 商品を梱包しない = do not pack
• 商品を梱包しなかった = did not pack

Because this is a する-verb, the conjugation happens on する, not on 梱包.

In modern standard Japanese, the particle を is pronounced お.

Historically, を had a different pronunciation, but in modern speech the object particle is normally just pronounced o.

So even though learners see:

• 商品を梱包します

they should say:

• しょうひん お こんぽうします

The special spelling is kept mainly because it helps show its grammatical role as the object particle.

Usually the strongest natural reading is to package/pack the goods, especially because of 梱包.

If you specifically want wrap, Japanese would more often use something like:

• 商品を包みます = wrap the item(s)

If you use 梱包します, the image is more like:

• packing into a box
• preparing for shipping
• securing items with packaging materials

So for most learners, it’s best to understand 梱包する as package / pack for shipment, not just wrap.
