Most of the usages of に I've seen have it directly followed by a verb directly attached to it. (The location of existance にある/にいる, The action objective e.g 私は電車に乗りました, etc)

I know there are some that don't directly have に follow a verb, but its still heavily reliant on a verb (私は六時に家を出る)

However, に can also be used when there are no verbs in the sentence

私に必要です Or 私には必要です

  • I interpret (at least the first sentence) as [smth] is essential to [me] or 私*

I (somewhat) get the fact that に and には mean kinda different things and are to be differentiated, so i will just refer to the first sentence.

What usage does the fall into here? Is there a certain way it gets applied in any sentence with only a noun/ adjective (as in it gets used the same way/ means the same thing)

Other maybe-related examples i found

タバコは体に悪い。 The way i see it (i guess) is that the に marks that tabacco is 悪い towards/ for the body/体. But why can't we use something like が here?

私に何か用ですか。 I guess this sentence works in a similar way to the 必要 one, labelling 私 as "What will i use/ be in use for me"

Sorry if this seems like an obvious question, but im genuinely stumped.

(Edited to explain how i see it)

  • how would you try to render those sentences in english? a good place to start is by showing us what you can already gather; we’ll be happy to fill in the blanks. that said, the particle に generally functions like the english prepositions to, in, on, at or for except in japanese particles follow the word they govern.

    FYI, 家を出す means "put out the house". Presumably you meant 家を出る.

As I said in my comment, the particle に can be rendered as in, on, at, to or for. It depends on the context which you’ll use.

にある/にいる identify where something (ある) or someone (いる) is. Lest you be confused by my parentheses here ある means is for nonanimate things (hence something); いる means is for living things, not just people (as someone might imply). In either case, ある/いる only mean is in the sense of location in space.

For example, に shows where something is. Here we’re talking about an animate object, a cat.


The cat is in the house.

Here’s an example with an inanimate object, a book.


The book is on the desk.

Let’s look at some of the examples you posted.


I got on the train.

Here に shows what you got on or in to ride someplace.


tobacco is bad for your body

Here に is best rendered as for

In a comment you asked why you couldn’t use が here. First, タバコは体が悪い, just doesn’t make sense. To see this a bit consider omitting talking about tabacco


would be saying

The body is bad

Your next example involved an expression of time. In time expressions に is usually rendered as at.


I leave the house at six

As for


This just means (literally)

It’s necessary for me.

or (more loosely but depending on context)

It’s important to me.

Your last example is somewhat idiosyncratic from the point of view of English and depending on your familiarity with other languages that have similar constructs, it may or may not come easily to you.


Generally this might be rendered fluently as

Do you need me for anything?

where the for anything is how I’m translating 何か; it has nothing to do with the particle に here. The わたしに part is just translated as me.

But this translation obscures what’s happening in the Japanese because in English this is the most natural way to render this particular type of question.

However a more strictly literal translation might make the grammar of this a bit more clear

Is there some kind of need for me?

Basically what you have here is the idiomatic expression


This is just the standrd way of asking, “is there something I can do for you?”

You can modify this form to express different but related ideas. For example, if you said something like


you be asking “do you have some kind of need (intended use) for this book?”

As you can see, you selected a diverse variety of uses for に. In a Japanese language class, each of these might be handled in separate lessons.

  • Thank you! I edited my post to show how i view things and most seemed to be kinda accurate, except for the last one. I guess its why i asked something like this in the first place, i interpreted it wrong. Can you explain 私に何か用です a little more please? Oct 8, 2020 at 13:26
