Crayon Shinchan the Movie: The Storm Called: The Battle of the Warring States

Shinnosuke Nohara (Akiko Yajima) is the kid from the long-running comedy series, and in this tenth film he somehow ends up in the age of the samurai. He wanders straight into their wars and court intrigue, and changes history left and right. Keiichi Hara wrote and directed it, the last film in the series drawn in traditional cel animation.
