#84 「〜ために vs 〜ように」 A Little Bit of Detailed Japanese Grammar

will vs be going to
must vs have to
can vs be able to
if vs whether

If you are an English speaker, could you explain the difference between each of these pairs? 😊

Language is interesting. When two expressions with very similar meanings continue to exist, there is often some difference in how they are used, the situations they appear in, or the nuance they carry.
Do these kinds of differences bother you?😩 Or perhaps they make you curious?😆

Personally, when learning a second or third language, especially as an adult, I do not think we need to understand every tiny difference.

I study foreign languages myself, and trying to remember every subtle nuance and use expressions as naturally as a native speaker can be exhausting.

For me, something else comes first:
Can the other person understand what I am trying to say?
I think it is perfectly fine for adult language learners to focus on that.
Even if the nuance is slightly different, there are many situations where it is enough simply to communicate your meaning clearly.

⚠️HOWEVER!!!🚨
Some learners still want to know the difference.
Some people simply enjoy finding out why two similar expressions are not quite the same.
And, to be fair, I completely understand that feeling🙂‍↕️

Whether you can actually use the difference in conversation is one thing. Sometimes, learning about the difference is simply interesting in itself✨

So, in this series, for those of you who really want to know these little differences, I will look at distinctions that are not only interesting to understand, but also practical enough to use in real Japanese.

This time, our topic is: 〜ために vs 〜ように
Both are often taught as expressions used to show a purpose, but they are not used in exactly the same way.

So, what is the difference?

So, how are 〜ために and 〜ように different?

Let us start with two common examples.

日本で働くために、日本語を勉強しています。
Nihon de hataraku tame ni, Nihongo o benkyō shite imasu.
I am studying Japanese in order to work in Japan.

日本語が話せるように、毎日練習しています。
Nihongo ga hanaseru yō ni, mainichi renshū shite imasu.
I practise every day so that I can speak Japanese.

At Basic level, you may sometimes see the difference explained like this:

〜ために is used with volitional verbs.
〜ように is used with non-volitional verbs.

Okay... I sort of understand the grammar rule, but what does that actually mean?💦
You may have wondered the same thing.

A useful way to think about it is this:
Is your goal an action you want to do? Or is it a state or result you want to reach?

An action or a result?

Imagine that you want to buy a new iPhone.📱
新しいiPhoneを買うために、お金を貯めています。
Atarashī iPhone o kau tame ni, okane o tamete imasu.
I am saving money to buy a new iPhone.

The goal is the action 買う — to buy, so ために works naturally.

Now imagine a parent preparing food for a small child.👩👶
子どもが食べられるように、食べ物を小さくします。
Kodomo ga taberareru yō ni, tabemono o chīsaku shimasu.
I make the food smaller so that my child can eat it.

Here, the goal is a state: the child is able to eat the food.

So, as a practical starting point:
〜ために → the goal is an action
〜ように → the goal is a state or result

What is a “non-volitional verb”?

Volitional verbs are fairly easy to imagine.
食べる — to eat
行く — to go
買う — to buy

These are normally actions you choose to do.

Potential forms are a useful example of the other side:
食べられる — can eat
話せる — can speak

They describe abilities.
ドリアンが食べられます。Dorian ga taberaremasu.
I can eat durian.
英語が話せます。Ēgo ga hanasemasu.
I can speak English.

You cannot normally switch these abilities on and off just because you decide to. If you can speak English now, you cannot decide that one second later you will suddenly be unable to speak it.

In that sense, these states are not directly controlled by your intention. That is a useful way to understand “non-volitional”.

わかる and 見える are similar

Potential forms are not the only examples.
Take わかる — to understand.
If understanding were completely under your control, you could simply think, “I want to understand Japanese”, and suddenly understand it.
You would have to be a genius✨ or a magician🪄.
You can choose to study, listen and practise. But わかる is the state that results from those actions.

The same idea applies to 見(み)える — to be visible / to be able to see. It describes something entering your field of vision rather than an action you intentionally perform.

That is why わかる, 見える, and potential forms often fit naturally with ように.

Put the idea back into the grammar

Compare:
日本で働くために、日本語を勉強しています。
Nihon de hataraku tame ni, Nihongo o benkyō shite imasu.

The goal is the action 働く — to work.

日本で働けるように、日本語を勉強しています。
Nihon de hatarakeru yō ni, Nihongo o benkyō shite imasu.

The goal is the state 働ける — to be able to work.

The situation may be almost identical. What changes is how you describe the goal.

More examples:
日本へ旅行するために、お金を貯めています。
Nihon e ryokō suru tame ni, okane o tamete imasu.
I am saving money to travel to Japan.

学生にも見えるように、字を大きく書きます。
Gakusē ni mo mieru yō ni, ji o ōkiku kakimasu.
I write in large letters so that the students can see them.

Again, the difference is whether you present the goal as an action or as a state/result.

What about negative forms?

You may also have learnt:
忘れないように、メモします。
Wasurenai yō ni, memo shimasu.
I make a note so that I do not forget.

遅れないように、早く家を出ます。
Okurenai yō ni, hayaku ie o demasu.
I leave home early so that I am not late.

Why does ように also connect with the negative form?
That is another interesting topic, but it would take us beyond this article.

For now, as a Basic-level shortcut, just remember:
negative form + ように

So, what is the trick?

When choosing between ために and ように, try to describe your goal clearly.

Am I focusing on an action I want to do?
→ ために
Am I focusing on a state or result I want to reach?
→ ように

If you can put that difference into words in your own mind, choosing between the two may become a little easier.

Reflection

That said, the same situation can look different depending on how you choose to describe it.

Not every example in Japanese can be divided perfectly into a ために box and a ように box. In many cases, the same idea can be rephrased, and changing the way you look at the goal can change the grammar you choose.

So please do not treat this distinction like a mathematical formula with zero exceptions.
Language is almost the opposite. It is full of exceptions, overlaps and grey areas.

Think of this article as one useful way to organise the difference in your head, rather than an absolute rule that explains every sentence in Japanese.
