SOFIS is a collective of representatives of each Sacred Heart School in Japan. It stands for the beginning letters of each of the five schools; Sapporo (Sapporo), Obayashi (Kobe), Fuji (Shizuoka), ISSH, and Sankocho (Tokyo). A workshop is held every year during the summer at one of the schools. Each year, a theme is given to the workshop, and the SOFIS group from each school prepares a presentation regarding the theme of the workshop. Several guest speakers visit the high school workshop and provide the students their life experience, to strengthen the student's knowledge about the theme. The goals of SOFIS is to deepen the bond between the Sacred Heart Schools in Japan and to provide an opportunity for the students to consider how they can contribute to society as a Sacred Heart student.
