Japan is steeped in history and tradition, and gender roles are closely linked to this
Discussing sexism in Japan is no easy task, sexism has permeated deeply into Japanese culture and the country is not comparable to other cultures that have had long established women’s rights campaigns. Sometimes sexist ideals are perpetuated by women themselves in Japan also, having a deep respect for tradition and a large proportion of traditionalists, both women and men. Furthermore, sexism is not contained to just educational institutions, with companies and even families arguably reinforcing gender differences.
For example there is a shortage of preschools and childcare in Japan, as so much of the population is centred around big cities. It is also not seen as a profitable industry, making it difficult for those in working childcare to live on very low wages. As a result many women opt to quit work when starting a family, as finding childcare may be too difficult. Furthermore, family pressure may feed into this also, as conservative husbands and older women of respective families may assume the wife should take up a traditional role in the family, and give up her career after having children.
Sexism is often seen as a necessary evil in Japan and changing one institution's acceptance policy for female students will not change this issue in any way. Some may even argue that what westerners call sexism could be a misunderstood cultural difference, for what may be seen by some people as virtuous and traditional behaviour.
