母 is the normal word for my mother when speaking about her to other people, especially in neutral or slightly formal Japanese. It is usually read はは in this kind of sentence.

お母さん is more often used when:

• speaking directly to your mother
• talking about someone else’s mother
• speaking from an in-family point of view

私の is omitted because it is already clear from context that the speaker means their own mother. Japanese often leaves out words that are obvious.

は marks the topic. It tells you that the sentence is about mother.

So 母は means something like:

• as for my mother
• speaking of my mother

It does not just mark the grammatical subject in a simple English way. It sets the frame for the rest of the sentence.

If this were 母が, the nuance would be different. が would sound more like identifying who did it, as in answering a question such as Who put the bag there?

防災 means disaster prevention or disaster preparedness.

ために means for, for the sake of, or for the purpose of.

So 防災のために means:

• for disaster preparedness
• in preparation for disasters
• for safety in case of disaster

It expresses purpose.

In this sentence, の is used to connect nouns or noun-like words. It is not always simple possession.

Here are the three の phrases:

• 防災のために
  for disaster preparedness

• 非常用の袋
  an emergency-use bag

• 玄関の近く
  the area near the entrance

So each の is linking one thing to another. You can think of it as a very flexible connector, often like of, for, or a noun modifier in English.

非常用 means for emergency use.

袋 means bag.

So 非常用の袋 literally means a bag for emergency use, or more naturally, an emergency bag.

The の is there because 非常用 is functioning like a noun modifier here. It connects emergency use to bag.

You may also see more compact words such as 防災袋 or 防災バッグ, but 非常用の袋 is a very understandable and natural phrase too.

玄関 means entrance or entryway.

近く means nearby area or vicinity.

So 玄関の近く means near the entrance.

The particle に is used because 置く is a verb of placement, and に marks the place where something is put.

For example:

• 机の上に本を置く = put a book on the desk
• 玄関の近くに袋を置く = put a bag near the entrance

Using で would sound wrong here, because で usually marks the place where an action happens, not the destination or placement location of an object.

Because 袋 is the direct object of 置く.

置く is a transitive verb meaning to put, to place, or to keep placed.

So:

• 袋を置く = place the bag

The thing being placed gets を.

置いています is the ている form of 置く.

Here, it shows a present ongoing state or a continuing arrangement. In natural English, it often feels like:

• keeps a bag near the entrance
• has placed a bag near the entrance
• leaves a bag near the entrance

If you used 置きます, it would sound more like a plain statement about an action, or something habitual stated more generally. 置いています is more natural when describing the current situation or arrangement.

Yes, that is possible, but the nuance changes.

置いてあります focuses more on the resulting state of the bag being intentionally placed somewhere.

For example:

• 非常用の袋が玄関の近くに置いてあります。
  There is an emergency bag placed near the entrance.

That version focuses on the bag and its state.

In your sentence, 母は ... 置いています focuses more naturally on what the mother does or what arrangement she keeps.

So both can be natural, but they highlight slightly different things.

Here are the main readings:

• 母 = はは
• 防災 = ぼうさい
• 非常用 = ひじょうよう
• 袋 = ふくろ
• 玄関 = げんかん
• 近く = ちかく
• 置いています = おいています

No. In normal Japanese writing, it would usually be written without spaces:

母は防災のために非常用の袋を玄関の近くに置いています。

Spaces are often added in learning materials to make the sentence easier to read, but standard Japanese usually does not separate words with spaces.
