If you have been studying Japanese for a few months, you have likely noticed a major turning point: moving from short, static descriptions like “I eat sushi” or “I can read kanji” to dynamic, nuanced expressions that describe how things change over time.
One of the most important grammar structures for bridging this gap is 〜ようになる (you ni naru).Includes real-world examples
Whether you are describing a skill you recently acquired, a shift in lifestyle, or a new habit, this single pattern acts as the primary engine for expressing personal progress and transition in everyday Japanese. In this comprehensive guide, we will break down 〜ようになる from its core concept and exact conjugation rules to real-life conversational nuances, subtle distinctions, and JLPT preparation strategies.
What Does 〜ようになる (You ni Naru) Mean?
At its core, 〜ようになる translates to:
- “To reach a point where…”
- “To become able to…”
- “To start doing (as a new habit/state)…”
It is formed by combining the noun よう (様 – appearance, way, state), the target particle に (ni), and the verb なる (成る – to become). Literally, you are saying that a situation or capability has “become a state where [verb] happens.”
It marks a transition from State A (cannot do / do not do) to State B (can do / regularly do).
Basic Structure and Conjugation
To form 〜ようになる, you attach the plain non-past form of a verb to ようになる.

4 Main Ways to Use 〜ようになる in Real Life
1. Acquisition of Skills (Becoming Able To Do Something)
This is the most common usage tested on the JLPT N4 exam. It emphasizes gradual development or the result of effort.
- 日本語の新聞が読めるようになりました。Nihongo no shinbun ga yomeru you ni narimashita.“I have reached the point where I can read Japanese newspapers.”
- 半年間練習して、ピアノが弾けるようになりました。Hantoshi-kan renshuu shite, piano ga hikeru you ni narimashita.“After practicing for half a year, I became able to play the piano.”
2. Shifts in Habits and Lifestyle (Starting a New Routine)
You can use standard verbs to show that something was not part of your daily life before, but is now a regular practice.
- 健康のために、毎日野菜を食べるようになりました。Kenkou no tame ni, mainichi yasai o taberu you ni narimashita.“For my health, I have come to eat vegetables every day.”
- 最近、夜遅く寝るようになってしまった。Saikin, yoru osoku neru you ni natte shimatta.“Lately, I’ve ended up getting into the habit of going to bed late.”
3. Natural or Automatic Changes (Environmental/State Changes)
Sometimes the change is not about personal effort, but an external process, age, or passage of time.
- 春になると、暖かくなって花が咲くようになります。Haru ni naru to, atatakaku natte hana ga siku you ni narimasu.“When spring comes, it gets warm and flowers start to bloom.”
- メガネをかければ、遠くの文字も見えるようになります。Megane o kakereba, tooku no moji mo mieru you ni narimasu.“If you put on glasses, you will become able to see distant characters.”
4. Expressing the Negative: 〜なくなる (To Stop / Become Unable To)
To express the opposite shift—where you lose an ability or stop a habit—replace なる with なくなる (from ない $\rightarrow$ なくなる).
- 忙しくて、運動しなくなりました。Isogashikute, undou shinaku narimashita.“Because I’m busy, I have stopped exercising.”
- お酒を飲まなくなりました。Osake o nomanaku narimashita.“I have stopped drinking alcohol / I don’t drink alcohol anymore.”
Important Nuances and Expert Insights
1. 〜ようになる vs. 〜ことができる (Dekiru)
Many learners confuse these two patterns because both relate to ability.
- 〜ことができる (koto ga dekiru): States an absolute capacity at a specific moment.
- 例: 私は漢字を読むことができます。(I can read kanji.)
- 〜ようになる (you ni naru): Emphasizes the process of change over time.
- 例: 漢字が読めるようになりました。(I reached a point where I can read kanji.)
Pro Tip: Use 〜ようになる when you want to highlight growth, effort, aging, recovery, or habit changes over time.
2. Emotional Weight and Tense Usage
When you use the past tense 〜ようになった (you ni natta), it often conveys personal pride, relief, or noticeable change:
- 一人で電車に乗れるようになった！(I can finally ride the train by myself!)
When used with 〜ようになっている (you ni natte iru), it describes a mechanism, system, or established rule:
- このドアは自動で開くようになっている。(This door is designed to open automatically.)
