“Shadow Education and Social Inequalities in Japan, Entrich presents the findings of work he conducted in Japan over a six-year period. As the title implies, the author is particularly interested in the effects of shadow education on students from different socio-economic backgrounds. … Shadow Education and Social Inequalities in Japan explores changes in the juku industry in more detail than any other study of this topic that I have read.” (Christopher Bjork, Pacific Affairs, Vol. 92 (1), March 2019)
