"School Health" is an online journal published by Japanese Association of School Health (JASH). JASH is an academic society supported by school health researchers, Yogo teachers, school teachers, and other professionals who are interested in school health. This journal was released in the year 2003, the 50th anniversary of JASH. We believe that this journal helps exchange knowledge and experiences in the fields of school health among people in many countries or regions. Anyone who would like to publish an academic paper or practical experiences can contribute the document in English to this journal. The full text of all articles can be accessed at this home page. We are looking forward to your submission.
