What Are Causative Verbs in Japanese?
Causative verbs allow the speaker to indicate that someone is causing another person to do something. In Japanese, this involves transforming the verb into its causative form. The causative construction is commonly used to show making, letting, or allowing someone to perform an action.
How to Form Causative Verbs
Japanese verbs are categorized into three groups, and the causative form is created differently for each:
- Group 1 (Godan verbs): Change the final -u to -aseru. For example, 書く (kaku, to write) becomes 書かせる (kakaseru, to make/let write).
- Group 2 (Ichidan verbs): Replace the final -ru with -saseru. For example, 食べる (taberu, to eat) becomes 食べさせる (tabesaseru, to make/let eat).
- Irregular verbs: する (suru, to do) becomes させる (saseru); くる (kuru, to come) becomes こさせる (kosaseru).
Examples of Causative Sentences
- 先生は学生に宿題をさせました。 (The teacher made the students do homework.)
- 母は子供に野菜を食べさせる。 (The mother lets/makes her child eat vegetables.)
What Are Causative-Passive Verbs in Japanese?
Causative-passive verbs combine the causative and passive voices. This form is used to express that someone was made to do something by another person, often against their will or expectation. The nuance here is that the subject is on the receiving end of an imposed action.
How to Form Causative-Passive Verbs
The causative-passive form is constructed by first making the verb causative, then converting that causative form to the passive:
- Group 1 (Godan verbs): Replace the final -u with -aserareru (often contracted to -asaseru in casual speech). For example, 書く (kaku) becomes 書かせられる (kakaserareru, to be made to write).
- Group 2 (Ichidan verbs): Replace -ru with -saserareru. For example, 食べる (taberu) becomes 食べさせられる (tabesaserareru, to be made to eat).
- Irregular verbs: する (suru) becomes させられる (saserareru); くる (kuru) becomes こさせられる (kosaserareru).
Examples of Causative-Passive Sentences
- 学生は先生に宿題をさせられました。 (The student was made to do homework by the teacher.)
- 子供は母に野菜を食べさせられる。 (The child is made to eat vegetables by the mother.)
Key Differences Between Causative and Causative-Passive Verbs
While both forms relate to causing actions, their perspectives and implications differ:
- Causative verbs focus on the person who makes or lets someone do something. The doer of the action is highlighted as being under someone else’s influence or permission.
- Causative-passive verbs emphasize the person who is made to do something, often involuntarily. The subject experiences an action imposed by someone else, commonly expressing inconvenience or reluctance.
Comparative Examples
- Causative: 先生は学生に漢字を書かせた。 (The teacher made the student write kanji.)
- Causative-passive: 学生は先生に漢字を書かせられた。 (The student was made to write kanji by the teacher.)
Why Understanding the Difference Matters
Mastering these verb forms is vital for accurate self-expression and understanding nuanced meanings in Japanese. Misusing causative and causative-passive forms can cause confusion or unintended implications in conversation. For learners using Talkpal and similar platforms, practicing these forms in context will build confidence and fluency.

Conclusion
Understanding the difference between causative and causative-passive verbs unlocks greater expressive power in Japanese.
