Ad campaign featuring Unko-sensei – aka Professor Poo – aims to help students appreciate the importance of the nation’s treasury

Japan’s government is hoping that children’s fascination with bodily functions will help them appreciate the importance of paying taxes when they reach adulthood.

Years after he fuelled huge sales of school textbooks, Unko-sensei [Professor Poo] has been enlisted by the finance ministry’s tax agency to appear in a brochure as part of a campaign to engender an appreciation of the role of the treasury among the nation’s youngest citizens.
