syuppin ha tyakubarai desu.

出品 is read しゅっぴん.

By itself, it literally means exhibiting or listing an item for sale. In online shopping or marketplace contexts, it often refers to the item/listing being offered.

So in this sentence, 出品は is understood as something like as for this listing/item.

着払い is read ちゃくばらい.

It means postage/shipping paid by the receiver upon delivery. In other words, the sender does not prepay the shipping cost; the person receiving the package pays it when it arrives.

In marketplace English, this is often explained as shipping paid by the buyer on delivery.

は marks the topic of the sentence.

So 出品は着払いです literally has the structure:

As for the listing/item, it is cash-on-delivery / postage-due.

Japanese often presents information as topic + comment. Here:

• 出品は = as for the listing/item
• 着払いです = it is sent postage due

A native English speaker may want to translate は as is, but it is better to think of it as a topic marker rather than a direct English word.

Because 着払い is the predicate noun of the sentence.

This sentence follows the pattern:

A は B です

which means:

A is B

So:

• 出品 = topic
• 着払い = what it is
• です = polite copula

There is no extra particle needed between 着払い and です.

です makes the sentence polite and works like is/am/are in this kind of sentence.

So:

• 着払いだ = plain style
• 着払いです = polite style

It does not add new meaning beyond politeness and sentence completion here.

Yes, the Japanese is compact in a way that sounds less natural if translated word-for-word.

A more natural English interpretation would be something like:

• This item ships postage due.
• Shipping is paid by the recipient.
• The buyer pays shipping on delivery.

Japanese often leaves out words that are obvious from context. Here, the idea of shipping is understood from 着払い, so it does not need to be stated explicitly.

Yes, probably.

A fuller version could be something like:

• この出品は着払いです。 = This listing is postage due.
• この商品は着払いです。 = This item is shipped postage due.
• 送料は着払いです。 = Shipping is paid on delivery.

Japanese often omits words like this, item, or shipping cost when the context is already clear.

It is understandable, especially in an online marketplace context, but it is somewhat compressed.

Depending on the situation, many speakers might more naturally say:

• この商品は着払いです。
• 送料は着払いです。
• こちらの出品は着払いになります。

So the original sentence is not wrong, but it feels like the kind of short statement you might see in a listing or app interface rather than careful, full conversational Japanese.

They are basically opposites in shopping contexts.

• 着払い = the receiver/buyer pays shipping upon delivery
• 送料込み = shipping cost is included in the price

So if a seller says 着払いです, the buyer should expect an extra shipping charge later. If they say 送料込みです, the listed price already covers shipping.

Using は makes 出品 the topic: as for this listing...

If you used が, the nuance would change. が tends to identify or emphasize the subject more directly.

In a simple marketplace statement, は is the more natural choice because the speaker is just giving information about the listing, not strongly identifying it.

So:

• 出品は着払いです = As for the listing, it is postage due
• 出品が着払いです would sound more contrastive or context-dependent

It is pronounced:

しゅっぴん は ちゃくばらい です。

A few pronunciation notes:

• 出品 has a small pause-like consonant in しゅっぴん
• 着払い is ちゃくばらい, not きばらい
• In natural speech, です may sound closer to des or a light de-su, depending on the speaker

Not exactly. 着払い is a noun, not an adjective.

So this is a noun-based sentence:

出品 は 着払い です A is B

This is why it behaves like:

• 学生です = is a student
• 便利です is different, because 便利 is a na-adjective/noun-like word
• 着払いです is best understood simply as it is postage due / cash on delivery

For learners, the safest approach is to memorize 着払い as a set term used in shipping and shopping contexts.
