School bullying has become a key issue of school safety in advanced countries for years. Taking account of there is not only similar social culture in Japan and Taiwan, since the mid-1980s, the Japanese government also has prioritized anti-bullying policies for the prevention of bullying in schools. This study examined the policy measures for the prevention of bullying in schools in Japan, using document analysis method, from the perspective of education law. The conclusions were as following: (1) anti-bullying policies for schools in Japan highlight the personal safety of students and prefer guidance measures rather than sanction measures; (2) Taiwanese government may benefit from emulating Japan with regard to legal accountability of stakeholders, framework of legislation for anti-bullying policies, and reporting systems for bullying in schools.
