hansyazai to amagu wo motte kuru.

Yes. Here, と is the particle that links two nouns, so it means and:

• 反射材と雨具 = reflective material and rain gear

In this sentence, it is simply listing the things to bring.

A small nuance: A と B usually sounds like a clear, complete list of those items, rather than a loose “things like A and B.”

Because 反射材と雨具 works as one combined noun phrase, and the whole phrase is the object of the verb.

So the structure is:

• 反射材と雨具 = reflective material and rain gear
• を = marks that whole phrase as the object
• 持ってくる = bring

You do not need to say:

• 反射材を雨具を持ってくる ✘

That would be ungrammatical here.

持ってくる is a combination of:

• 持つ = to hold / to carry
• 来る = to come

When 持つ becomes 持って and combines with くる, it means:

• to bring
• literally, to come carrying something

So:

• 持つ = hold/carry
• 来る = come
• 持ってくる = bring

This is a very common pattern in Japanese.

It is very close to English bring, but the Japanese expression makes the physical image a bit clearer: you come while carrying the item.

So 反射材と雨具を持ってくる is literally something like:

• come bringing reflective material and rain gear
• or more naturally, bring reflective material and rain gear

In everyday English, we usually just say bring, but Japanese often builds that meaning more transparently.

This is a very common learner question.

• 持ってくる = bring it here / to the destination from the speaker’s or context’s viewpoint
• 持っていく = take it away / to somewhere else from the current location

Compare:

• 明日、雨具を持ってきてください。
  = Please bring rain gear tomorrow.

• 学校に雨具を持っていってください。
  = Please take rain gear to school.

In practice, English may use bring or take depending on perspective, and Japanese does the same through くる vs いく.

Japanese often leaves out the subject when it is obvious from context.

So this sentence could imply:

• you should bring reflective material and rain gear
• participants should bring reflective material and rain gear
• please bring reflective material and rain gear

The exact subject depends on where the sentence appears:

• on a notice
• in event instructions
• in a checklist
• in a school or workplace announcement

Omitting the subject is completely normal in Japanese.

Because this kind of sentence often appears in:

• lists
• instructions
• notices
• headings
• brief written directions

In those contexts, plain form can sound concise and natural.

So 反射材と雨具を持ってくる。 may function like:

• Bring reflective material and rain gear.
• To bring: reflective material and rain gear.
• Bring reflective material and rain gear along.

If someone were speaking politely to you directly, they might say:

• 反射材と雨具を持ってきてください。
  = Please bring reflective material and rain gear.

The readings are:

• 反射材 → はんしゃざい
• 雨具 → あまぐ
• 持ってくる → もってくる

So the full sentence is read:

• はんしゃざい と あまぐ を もってくる。

Both are possible, but writing くる in hiragana is very common, especially in combinations like:

• 持ってくる
• 連れてくる
• 買ってくる

Japanese often writes very common auxiliary-like verbs in hiragana because it looks more natural and is easier to read.

So these are both possible:

• 持ってくる
• 持って来る

The hiragana version is extremely common.

Japanese nouns usually do not mark singular vs plural the way English does.

So 反射材 could mean:

• a reflective item
• reflective material
• reflective gear/materials in general

Likewise, 雨具 can mean:

• rain gear
• rain equipment
• rainwear

The exact interpretation depends on context. In an instruction like this, it usually means the item(s) needed, not necessarily exactly one piece.

Yes. In Japanese, short plain-form sentences in notices or instructions often function like commands or reminders without using an explicit imperative.

So depending on context, 反射材と雨具を持ってくる。 might feel like:

• Bring reflective material and rain gear.
• Be sure to bring reflective material and rain gear.
• You need to bring reflective material and rain gear.

Japanese often relies on context and style rather than always marking commands directly.
