Senri & Osaka International Schools of Kwansei Gakuin

Two Schools, One Campus, One Mission.


More than 35 nationalities are represented on the campus, creating a truly international learning and social environment.


OIS was the first school in Japan to offer all three IB programmes, and now has over 25 years' experience as an IB World School.

Super Global High School

From 2015, SIS was assigned as a "Super Global High School" (SGH) by MeXT. Click the icon for more information.

IB DP RESULTS: The OIS class of 2020 have now graduated with another very good set of results. All IB DP candidates successfully passed the Diploma, with an average score over 36 points (20% above the world average), with 33% of the cohort scoring 40 points or more, placing them in the top 10% of DP results worldwide. The Spring trimester was challenging for everyone, particularly the G12s who faced a great deal of uncertainty over exams, grades and university place. Our seniors acquitted themselves very well in difficult circumstances, and we wish everyone all the best at college or in their chosen careers.

Novel Coronavirus updates:

OIS and SIS restarted on-campus learning on August 24. The schools have sent information to all members of the SOIS community about adjustments that have been made to protect students, teachers and staff over the coming trimester.
