CRC/C/15/Add.231 page 11 (f) language; Children of minorities have very limited opportunities for education in their own (g) Despite review procedures, some history textbooks are incomplete or one-sided. 50. The Committee recommends that the State party: (a) Taking into account the views of students, parents and relevant non-governmental organizations, review the curriculum with a view to reducing the competitiveness of the school system while maintaining a high level of quality of education so as to ensure that all students graduating from high school have equal access to higher education; (b) Develop measures, in collaboration with students and parents, to effectively address problems and conflicts in schools, in particular violence, including bullying; (c) Encourage the Tokyo authorities to reconsider the closing down of night schools, and to expand alternative forms of education; (d) Expand opportunities for children from minority groups to enjoy their own culture, profess or practise their own religion and use their own language; (e) Strengthen review procedures for textbooks to ensure that they present a balanced view. 8. Special protection measures Sexual exploitation and trafficking 51. As noted in paragraph 3 above, the Committee welcomes the adoption and implementation of the Law on Punishing Acts related to Child Prostitution and Child Pornography and on Protecting Children (1999). However, it is concerned that: (a) The Penal Code maintains a narrow definition of rape as an act committed by a male against a female; (b) All victims of sexual exploitation do not have access to appropriate recovery and assistance services; (c) There have been reports of child victims being treated as criminals; (d) There have been reports of the practice of “enjo kosai”, or compensated dating; (e) The low minimum age of consent, which might contribute to the practice of “enjo kosai”, hampers the prosecution of sexual abuse of children.
