SOFIS stands for the first letters of the five Sacred Heart schools in Japan: Sapporo (Hokkaido), Obayashi (Hyōgo), Fuji (Shizuoka), ISSH, and Sankocho (Tokyo). During the summer vacation, a few high school students from each of these schools were selected to participate in an annual workshop. Five students from the International School of the Sacred Heart were able to attend this August. Each year, the workshop aims to strengthen the bonds between the sister schools while providing an opportunity for students to consider their ways of contributing to society.

Every year, students deepen their knowledge by giving informative presentations and listening to several lectures by guest speakers that address a current global issue. They also visit several companies, organizations, and events to gain further knowledge regarding the issue. This event is especially challenging for the ISSH students as they are required to only interact in Japanese. Therefore, students are further encouraged to develop their Japanese skills and learn more about Japanese culture during this event. This workshop provides students with a rewarding experience and education, which they can bring back to their schools and act upon their newly attained knowledge.

The Sapporo Sacred Heart School hosted the 2019 SOFIS event, where students discussed the Sustainable Development Goals (SDGs) set by the United Nations. The students also exchanged views on how humans can live in harmony with nature to achieve a more sustainable future for all.
