Japanese passive, causative and causative-passive expressions are intricate for learners. To promote understanding and production, we present a skit making classroom activity named "Bunpoo Dorama" (grammar drama). The groups of learners are presented with the sets of target sentences which describe incidents from the viewpoint of the giver and the receiver of the action. Each group creates a skit to show the situation which leads to the given target sentences. After the performance, the class tries to reproduce the target sentences concentrating on the voice expressions. We exhibit the implemental method, the responses of learners, and discuss the potentials of this activity.
