This study discusses the disparity in numbers between Japanese children and their Brazilian immigrant peers concerning placement in Japanese special education classes. In-depth interviews were conducted with 21 stakeholders including Japanese nationals and Brazilian immigrants to see if there were any ways to explain the larger numbers of immigrant children assigned to such classes. Five main factors affecting the stakeholders emerged: Linguistic and Cultural Related Misunderstandings of Information, Limitations Concerning Counseling and Educational Planning, Requests for Improving the Support System for Non-Japanese Students, Importance of a Second Opinion, and Cultural and Linguistic Effects when Evaluating Non-Japanese Students. The study provides policy recommendations aimed at improving the support system for immigrant communities who face a variety of stresses living in an unfamiliar culture.
