About Unko Sensei

What do children hate? Studying.
What do children love? POOP!

Unko Sensei is a teacher who combines the two together in a new “study workbook” which fuses “poop” x “learning.”

Since its release in March 2017,
“The Poop Workbook Series” has become a massive hit.
It has sold a total of 5 million copies, where every 2 in 3 elementary school children in Japan own a copy.

With his unique coloring and lovable figure,
Unko Sensei has established himself as the new classic character that represents studying!

Unko Sensei’s Mission

To make learning (education) fun!

UNKO Project

To realize you are actually learning while you are playing.
To realize you are having fun while studying.

Unko Sensei improves the formative experience of “learning” and changes these “first” experiences that children have into something better.
By liking Unko Sensei, one is led to have positive experiences such as, “growing one’s strengths”, “overcoming one’s weaknesses”, and “becoming more curious.”
Our wish is for Unko Sensei to be a figure who offers children the “future.”
