haha ha, daikon to kinoko wo tukatte, atatakai udon wo tukurimasita.

は marks 母 as the topic: As for my mother, ...

That is a very natural choice here because the sentence is simply telling you what she did.

If you used が instead, it would put more focus on mother as the one who did the action, as if answering a question like Who made the udon?

• 母は = As for my mother, she made...
• 母が = My mother is the one who made...

Both can be grammatical, but は fits this neutral statement well.

In this sentence, 母 normally means my mother.

Japanese often does not use words like my when the relationship is clear from context. Also, when talking about your own mother to other people, 母 is the usual humble/plain form.

A useful contrast:

• 母 = my mother, when referring to her from your side
• お母さん = mom / mother, often when addressing her directly or referring to someone else’s mother more politely

So here, 母は is most naturally understood as My mother...

と connects nouns and means and.

So:

• 大根ときのこ = daikon and mushrooms

This use of と usually sounds like a complete, definite list. In other words, it suggests these are the ingredients being named.

If the speaker wanted to give a non-exhaustive list, Japanese often uses や instead:

• 大根やきのこ = things like daikon and mushrooms

But in your sentence, と is the natural choice for a straightforward A and B.

Yes. This sentence has two different verbs involved, and each verb has its own object.

• 大根ときのこを使って
  = using daikon and mushrooms
• 温かいうどんを作りました
  = made warm udon

So the first を belongs with 使って from 使う (to use), and the second を belongs with 作りました from 作る (to make).

Even though 使って is not the final verb, it still keeps its own object.

You can think of the structure like this:

• [daikon and mushrooms]
  • use
• [warm udon]
  • make

That is why two を markers are perfectly fine here.

使って is the て-form of 使う (to use).

In this sentence, it links two actions:

1. using daikon and mushrooms
2. making warm udon

So:

• 大根ときのこを使って、温かいうどんを作りました。
• Using daikon and mushrooms, (she) made warm udon.

The て-form often connects actions or shows the means/method for the main action. Here it means something like using or with.

A very common pattern is:

• Aを使って Bを作る
• make B using A

Because Japanese adjectives normally come before the noun they describe.

So:

• 温かいうどん = warm udon

This is similar to English word order in phrases like:

• warm soup
• cold water
• new book

Also, 温かい is an い-adjective, so it can directly modify a noun with no extra word needed.

• 温かい うどん
• not 温かな うどん

That is because 温かい is an い-adjective, not a な-adjective.

Because 温かい is the plain form used when directly modifying a noun.

When an い-adjective comes before a noun, it stays in its basic attributive form:

• 温かい うどん = warm udon

Other forms have different jobs:

• 温かく = adverb-like form, as in become warm or serve warmly
• 温かかった = was warm

So here, since it is simply describing the noun うどん, 温かい is the correct form.

作りました is the polite past form of 作る (to make).

It tells you two things:

1. Past tense: the action is completed
   
   • she made it
2. Polite style: the sentence is in ます style

Related forms:

• 作る = plain dictionary form
• 作ります = polite non-past
• 作った = plain past
• 作りました = polite past

So the sentence is politely saying that the mother made the udon.

Japanese word order is more flexible than English word order, because particles show each word’s role.

The most important thing is that the main verb usually comes at the end:

• 母は、大根ときのこを使って、温かいうどんを作りました。

This order is very natural:

1. topic
2. ingredients / method
3. thing made
4. final verb

Some parts can move, but not all versions sound equally natural. For example, Japanese usually keeps descriptive chunks together:

• 温かいうどん should stay together
• 大根ときのこを使って should stay together

So yes, there is some flexibility, but the original sentence is a very normal, easy-to-understand order.

Because Japanese often leaves out information that is obvious from context.

In English, you usually need to say my mother. In Japanese, just 母 is often enough, because listeners naturally understand that the speaker means their own mother.

This is extremely common in Japanese:

• 母 = my mother
• 父 = my father
• 兄 = my older brother

So the possessive idea is there, but it is understood rather than stated.

The commas help organize the sentence and make it easier to read.

• 母は、
• 大根ときのこを使って、
• 温かいうどんを作りました。

They mark natural pauses and separate chunks of information.

They are helpful, but they are not always strictly necessary. Japanese punctuation is often more flexible than English punctuation. A sentence like this could also appear with fewer commas, especially in casual writing.

So the commas are mainly there for readability.

Yes. That is often a very natural English translation.

Literally, it is using daikon and mushrooms, but in smoother English you might say:

• My mother made warm udon with daikon and mushrooms.

That does not change the Japanese grammar. The Japanese still uses the verb 使う (to use), but English may prefer with instead of using, depending on style.

So both of these capture the meaning well:

• using daikon and mushrooms
• with daikon and mushrooms
