The Prime Minister recurs as a minor character throughout various GeGeGe no Kitarō adaptations. This government figure directly confronts supernatural events and characters, especially during crises endangering Japan.

In one storyline, the Prime Minister faces peril from a yōkai threat, requiring rescue by Kitarō's intervention. Expressing gratitude, the Prime Minister offers Kitarō Japanese citizenship, which Kitarō declines, accepting only a simple cup of coffee instead.

The character occasionally becomes a target for opportunistic yōkai like Nezumi-Otoko, who attempts conspiracies aimed at concerned authority figures. The Prime Minister also masterminds national security responses during large-scale supernatural incidents, including mysterious explosions or other public disturbances caused by yōkai activities.
