Understanding Causative Form in Japanese
The causative form in Japanese is used to express situations where someone makes or allows another person to do something. This grammatical structure is essential for both beginners and intermediate learners as it plays a vital role in daily conversations and formal settings.
Formation of the Causative Form
The causative form in Japanese follows a specific conjugation pattern based on the verb group.
Group 1 (Ichidan Verbs – る-verbs)
- Drop る and add させる
- Example: 食べる → 食べさせる (taberu → tabesaseru) – “to make/let someone eat”
Group 2 (Godan Verbs – う-verbs)
- Change the final う sound to あ and add せる
- Example: 書く → 書かせる (kaku → kakaseru) – “to make/let someone write”
Irregular Verbs
- する → させる
- くる → こさせる

3. When Used with Intransitive Verbs

- The causative form can indicate both “making someone do” and “letting someone do” an action.
- The causative-passive form (e.g., やらせられる) is often used when someone is forced to do something against their will.
- The particle に is used to indicate the person being caused to act.
- Some sentences may sound unnatural if used without context, so always consider the situation.
Conclusion
The causative form in Japanese is essential for expressing permission, coercion, and obligation. Mastering it will help you create more nuanced sentences in conversations and formal settings. Keep practicing with different verbs and contexts, and soon, using the causative form will become second nature!
