は marks the topic of the sentence.

So 私たちは means as for us or speaking of us. In natural English, this usually just becomes we.

A useful point for learners: は is not exactly the same as an English subject marker. It sets up what the sentence is about. In many simple sentences, the topic and the subject happen to be the same, so it is often translated as we here.

Also, although it is written with the kana は, when used as a particle it is pronounced わ.

Because 安全 is a na-adjective (or adjectival noun), not an i-adjective.

In Japanese, there are two main adjective types:

• i-adjectives: like 高い
• na-adjectives: like 静か, 便利, 安全

When a na-adjective comes directly before a noun, you add な:

• 安全な場所 = a safe place
• 静かな部屋 = a quiet room

So 安全な場所 is correct because 安全 needs な before the noun 場所.

を marks the direct object of the verb.

Here, 場所を確保する means that place is the thing being secured.

So the structure is:

• 私たちは = as for us / we
• 安全な場所を = a safe place
• 確保する = secure / ensure / obtain

In other words, we secure a safe place.

確保する is a common suru-verb that means things like:

• to secure
• to ensure
• to guarantee
• to obtain and keep available

The exact English translation depends on context.

For example, 安全な場所を確保する could mean:

• secure a safe place
• ensure a safe location
• obtain a safe place for use

It often has a practical, slightly formal feeling. It is used for making sure something necessary is available, protected, or set aside.

Because Japanese is usually a verb-final language.

A very common basic order is:

• topic + object + verb

So:

• 私たちは = topic
• 安全な場所を = object
• 確保する = verb

This is different from English, which usually puts the verb earlier:

• We secure a safe place.

In Japanese, the main verb often comes at the end of the sentence.

Yes, it can often be omitted.

Japanese frequently leaves out subjects or topics when they are clear from context. So if everyone already knows who we refers to, you could simply say:

• 安全な場所を確保する。

That could still mean We secure a safe place or We will secure a safe place, depending on context.

Japanese tends to avoid repeating pronouns when they are already understood.

確保する is the plain non-past form.

The Japanese non-past can mean:

• a habitual action: we secure
• a future action: we will secure
• a general statement: we secure / we ensure

So the exact time depends on context.

If you wanted the polite form, you would say:

• 確保します

So:

• 確保する = plain
• 確保します = polite

The sentence you were given is in plain style, which is common in textbooks, dictionaries, headlines, written plans, and explanatory examples.

It is a straightforward modifier + noun combination:

• 安全な = safe
• 場所 = place/location

Together:

• 安全な場所 = a safe place

There is no extra word like of or that is in Japanese here. The adjective simply comes before the noun, just like in English.

確保 is a verbal noun. This means it can combine with する to make a verb:

• 確保 = securing / securing something
• 確保する = to secure

This is very common in Japanese. Many Sino-Japanese words work like this:

• 勉強する = to study
• 準備する = to prepare
• 確認する = to confirm
• 確保する = to secure

So instead of being a standalone native verb, 確保する is built from a noun plus する.

It is read:

わたしたちは あんぜんな ばしょを かくほする

A few useful reading notes:

• 私たち = わたしたち
• 安全 = あんぜん
• 場所 = ばしょ
• 確保する = かくほする
• The particle は is pronounced わ
• The particle を is usually pronounced お

No, standard Japanese normally does not use spaces between words.

The normal writing would be:

私たちは安全な場所を確保する。

Spaces are often added in beginner materials to make word boundaries easier to see. They are a teaching aid, not standard punctuation.

Yes. 場所 can mean:

• place
• location
• spot
• area

The best English choice depends on context.

So 安全な場所を確保する could also be translated as:

• secure a safe location
• ensure a safe area

In many cases, place is the simplest translation, but location may sound more natural in formal or practical contexts.

Grammatically, は marks the topic, not specifically the subject.

In this sentence, 私たち is also understood as the doer of the action, so in practice it corresponds to the English subject we. But it is still helpful to remember that Japanese and English do not divide sentences in exactly the same way.

A rough way to think about it is:

• 私たちは = as for us
• 安全な場所を確保する = secure a safe place

So 私たち is the topic, and semantically it is also the one performing the action.

Sometimes yes, but it changes the nuance.

• 私たちは安全な場所を確保する。
  = As for us, we secure a safe place.

• 私たちが安全な場所を確保する。
  = We are the ones who secure a safe place.

Using が tends to highlight or identify who does the action. Using は presents we as the topic more neutrally.

In many beginner sentences, は is used because it is the most neutral topic marker.
