〜ようになる: Meaning, Conjugation & 12 Examples

The shift from "couldn't" to "can"

Here's the nice thing: you already know both halves of this pattern. There's よう (a way or manner of being) and なる (to become). Put them together and you get the feeling of gradually becoming a certain way — "to come to do," "to start doing," or "to become able to."

The one idea to hold onto is change. Something used to not be the case, and now it is. And usually that change is gradual or natural rather than a sudden flip of a switch — it's the result of time passing, practice adding up, or circumstances shifting. That "slow build" feeling is the heart of ようになる, and it's what separates it from just stating a fact.

In real life, the change tends to come in three everyday flavors:

• a new habit — 毎日運動するようになった ("I've come to exercise every day"),
• a new ability — 日本語が話せるようになった ("I've become able to speak Japanese"), and
• a change that just sort of happened to you — 子どもが野菜を食べるようになった ("my kid started eating vegetables").

Because the whole point is the transition, you'll almost always see ようになる in the past tense (なった / なりました) when you're talking about a change that's already happened. If you keep it in the present (なる), you're pointing at a change that's still to come.

One quick heads-up before we go further: this is the pattern people mix up with 〜ようにする ("to make an effort to do"). The trick is small but it sticks — なる means the change happens, while する means you make it happen. We'll come back to this with examples a bit further down, so don't worry about it yet.

A quick feel for it

Imagine a friend asks how your Japanese is going, and you say:

最初は全然できなかったけど、毎日少しずつ勉強して、今は新聞が読めるようになりました。 "At first I couldn't do it at all, but I studied a little every day, and now I've become able to read the newspaper."

Feel that arc? "Couldn't before → effort over time → can now." Whenever your sentence has that shape, ようになる is exactly the tool you want.

Dictionary form for habits, potential form for abilities

Good news — the formation is short and forgiving. The only real choice you make is which verb form to attach it to, and that follows straight from your meaning: dictionary form when a plain action becomes routine, potential form when a new ability appears.

That potential-form row does a lot of quiet work. "I can read kanji now" needs 漢字が読めるようになった; without the potential, 漢字を読むようになった only says you picked up the habit of reading kanji — a genuinely different idea. So when the point is a newfound ability, always run the verb through its potential form first.

About that negative. You can technically say 〜ないようになる, but honestly, native speakers rarely do. When you want "to stop doing / come not to do," reach for 〜なくなる instead — it just sounds more natural:

• ✅ お酒を飲まなくなった。 — "I stopped drinking alcohol."
• △ お酒を飲まないようになった。 (not wrong, but it'll sound a little off)

One thing to watch: ようになる is for verbs. If you want to say something became a certain way using an adjective or a noun, you don't need よう at all — plain なる does the job:

• 寒くなる — "to get cold" (い-adjective: 寒い → 寒く)
• 元気になる — "to get well" (な-adjective: 元気 → 元気に)
• 先生になる — "to become a teacher" (noun + に)

So save ようになる for verbs (actions and abilities), and use plain なる for adjectives and nouns.

Ten sentences that show the change

Reading real sentences is the fastest way to get a feel for this one, so here are a dozen in context:

Little touches that make it sound native

• Tense. Reach for the past (〜ようになった/なりました) when the change has already happened — that's the most common case. The present (〜ようになる) is for changes you're predicting or describing in general.
• Words that pair nicely. だんだん (gradually), 少しずつ (little by little), 最近 (recently), and やっと / ようやく (finally) all play up the sense of transition — sprinkle them in and your sentence instantly sounds more natural.
• Where you can use it. Everywhere, really. It's perfectly at home in both casual chat and polite speech, and it shows up all over the JLPT.

Two close cousins: 〜ようになってきた and 〜ようになっている

Once the basic pattern feels comfortable, two close cousins are worth knowing — they're common and they add real precision:

• 〜ようになってきた highlights a change that's been building up to now. 漢字が読めるようになってきた = "I've gradually been getting able to read kanji (and it's still going)." It's perfect for progress you're in the middle of.
• 〜ようになっている describes the change as a settled, current state. このアプリは無料で使えるようになっている = "This app is (now) set up so you can use it for free." The shift already happened, and you're describing how things stand.

You don't need these to pass N4, but recognizing them will make reading and listening feel much smoother.

When the change is instant, skip it

A quick reality check, because over-using it is a common habit. ようになる is about a change you grow into. For a one-time, instant change, plain なる or just the past tense is more natural:

• 信号が赤になった。 — "The light turned red." (instant — not 赤になるようになった)
• 急に雨が降ってきた。 — "It suddenly started to rain." (sudden — ようになる would feel wrong)

If there's no sense of "over time," you probably don't need ようになる.

The slip-ups worth knowing about

Every learner stumbles on these at first, so if any look familiar, you're in good company:

1. Mixing it up with ようにする. If you're describing a result — "I ended up studying every day" — that's 勉強するようになった. If you're describing your effort or decision, that's 勉強するようにしている. More on this just below.
2. Forcing the negative into ないようになる. Go with なくなる instead — your sentences will sound more like a native's.
3. Using a plain verb when you mean an ability. "I can read kanji now" needs the potential form: 漢字が読めるようになった. Without it, 漢字を読むようになった means you picked up the habit of reading kanji — a different idea.
4. Adding よう to an adjective. It's 寒くなる, not 寒いようになる. Remember: よう is only for verbs.

なる or する? Who's driving the change

This is the question almost everyone asks, so let's settle it side by side:

If you only remember one thing: なる = it becomes; する = I make it so. Picture it this way — with なる, you're describing the outcome you ended up at; with する, you're describing the choice you keep making. So 毎朝走るようになった says running became part of your life, while 毎朝走るようにしている says you're deliberately keeping up the habit.

And don't confuse it with ことになる, either: that one is about a decision or arrangement ("it's been decided that…"), not a gradual change. Want the full picture with lots more examples? We wrote a whole guide on it: ようになる vs ようにする.

The whole thing in five lines

• ようになる = a change over time: couldn't/didn't before → can/do now.
• Attach to a verb's dictionary form (habit) or potential form (ability).
• Negative is usually 〜なくなる, not ないようになる.
• Verbs only — adjectives and nouns just take plain なる.
• なる = it becomes; する = you make it happen.

Put it into practice

The best way to lock this in is to actually use it. Try a few:
