We developed the world's most tedious class to make you sleepy, in order to improve your grades!

A special site was opened and launched between March and September 2015.

The lesson was offered to around one million students and was watched 380,000 times.

TV news programs ran stories on the project, describing what had now become a unique lesson for the students taking their exams.

'JYUKEN SAPURI' has now grown to become used by one in two students, recognized as a premier online lesson service for students.
