International Educational Exchange
 SEIFU has been making great efforts to promote international understanding through its growing exchange student program and the establishment of twin-school ties with schools in other countries.

 SEIFU has a twin-school relationship with Brisbane Grammar School in Australia and The Royal Wolverhampton School, Monmouth School in the United Kingdom, Beijing University Secondary School in China, and Soul Traditional Art High School and hopes to increase such ties in the future.
 The aim of these programs is to produce adults who  will take an active role in the community of nations.
 Realizing the vital importance of language education in  this endeavor, SEIFU employs a number of native speaker English teachers.

In addition to the regular exchange of students with its twin schools, SEIFU has also hosted participants in exchange programs sponsored by the Lions Club, the Rotary Club, AFS (American Field Service) and other organizations. Students from Australia, Brazil, Korea, New Zealand, Singapore, the UK and the USA have had the opportunity to create individualized study
programs, combining their choice of academic subjects with tutorial instruction in Japanese language and culture.
Exchange students may apply for partial grants to cover some of their school expenses. The chairman of the board of trustees has the authority to decide on the distribution of these funds.
