Transitivity in Japanese explains whether an action happens by itself or is done to something. This is a key grammar concept for N4 and N3.
Basic Meaning
- jidoushi (intransitive): no direct object, event happens
- tadoushi (transitive): takes direct object, someone causes action
High Value Verb Pairs
- aku (opens by itself) vs. akeru (open something)
- shimaru (closes) vs. shimeru (close something)
- tsuku (turns on) vs. tsukeru (turn on something)
Sentence Pattern Difference

Why Learners Struggle

- Practice both sentences for each pair
- Highlight particles while reviewing
