Criticisms

There is also criticism about the amount of free time students are given and/or are allowed within their middle school and high school careers. As Japanese students grow, their time to assert what they have learned in class to real life is cut dramatically, starting with the elevation from elementary to lower secondary school. A large part of this has to do with cram schooling, or Juku, which can start as early as elementary and takes full effect toward the end of junior high school, with roughly 60% of all students participating. This number has increased drastically over the past couple decades, as well as the view of Juku within the Japanese academic system. While initially seen as a problem, cram schools have become synonymous with Japan's schooling and are even seen as a support to the structure of said schooling. With Juku costing between 600,000 and 1.5 million yen, depending on how old the student is and how much the guardian can pay, cram school is a very profitable part of the economy, with over 48,000 Juku schools active today. With these extra school sessions ranging between 1 and 6 days a week on top of normal classes, there is a fear that students will be unable to incorporate what they have learned into their lives, and thus could foreseeably lose the retained knowledge once the Entrance Exams are over.
