Master N3 Grammar: ように vs. ために (Expressing Purpose)

In Japanese, expressing "in order to" or "so that" is crucial for explaining your motivations and goals. At the JLPT N3 level, you must master the distinction between ために (tame ni) and ように (yō ni). While both translate to "for the purpose of," they require different grammatical environments.

Let’s break down the rules so you never mix them up again!

1. 〜ために: The Goal-Oriented "In Order To"

Use ために when you have a concrete, controllable goal and you are taking direct action to achieve it.

Grammatical Rules

• Verb (Dictionary Form) + ために
• Noun + のために

⚠️ Crucial Rule: The verb preceding ために must be volitional (an action you can consciously control, like buy, study, go). Additionally, the subject of both clauses must be the same.

Examples

• 日本に留学するために、貯金しています。
  • Nihon ni ryūgaku suru tame ni, chokin shite imasu.
  • In order to study abroad in Japan, I am saving money.
  • (Reason: "Studying abroad" is a conscious, controllable action.)
  日本留学貯金
• 家族のために、一生懸命働きます。
  • Kazoku no tame ni, isshōkenmei hatarakimasu.
  • I work hard for the sake of my family.
  家族一生懸命

2. 〜ように: The State-Oriented "So That"

Use ように when you are aiming for a desired state or outcome that is not entirely under your direct, immediate control. You are doing an action so that a certain condition becomes possible.

Grammatical Rules

• Verb (Potential Form) + ように (e.g., 話せる, 買える)話買
• Verb (Negative Form / ない-form) + ように (e.g., 忘れない, 遅れない)忘遅
• Verb (Non-volitional/State) + ように (e.g., 分かる, 見える, 治る)分見治

⚠️ Crucial Rule: The verb preceding ように must be non-volitional (potential, negative, or state verbs).

Examples

• 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 practice every day so that I can speak Japanese.
  • (Reason: "To be able to speak" is a potential state, not a direct action.)
  日本語話毎練
• 忘れないように、メモ帳に書いておきます。
  • Wasurenai yō ni, memochō ni kaite okimasu.
  • I will write it down in my notebook so that I don't forget.
  • (Reason: "Not forgetting" is a negative state; you cannot directly "force" your brain not to forget.)
  忘帳書

Pro-Tip: The "Negative" Cheat Code

If the purpose clause is negative (e.g., "so that I don't..."), always use ように. You cannot use ために with negative verbs.

• ❌ 遅れないために (Incorrect)遅
• ⭕️ 遅れないように (Correct - so that I won't be late)遅
