How To Use It
Use Conditional correctly
Simple Explanation
Use this pattern when you need to connect an idea clearly in a JLPT N4 sentence. Learn the pattern first, then read several examples until the order feels natural.
Sentence Structure
あめが [correct form / particle] 、ピクニック は キャンセルです。
Start with this simple structure before making longer sentences.
When To Use
Use it in beginner reading, short answers, daily-life examples, and JLPT review questions where the topic appears naturally.
When Not To Use
Do not force it into every sentence. If another word, particle, or grammar pattern expresses the idea more naturally, choose that instead.
- Japanese learners grow faster when they notice how this topic appears in everyday routines, classroom language, and common study examples.
- Even simple grammar lessons become more memorable when students connect them to real situations instead of treating them like a word list only.

〜たら (Tara) - 'If / When'
This is the most common and versatile conditional. It means 'If X happens' or 'When X finishes'.
- How to make it: Take the Past tense of any verb/adjective (Ta-form) and add 'ra'.
- E.g., Iku -> Itta -> Ittara (If you go).
- E.g., Samui -> Samukatta -> Samukattara (If it's cold).
〜ば (Ba) - The Logical Condition
Used for logical facts or strong requirements ('Provided that X happens').
- How to make it: Change the final 'u' sound to 'e' and add 'ba'.
- E.g., Iku -> Iku -> Ike -> Ikeba (If you go).
- E.g., Nomu -> Nome -> Nomeba.
