SEISA history

50 years of SEISA history

Throughout its 50-year history, SEISA has continued to create “what is necessary for the society" in the fields of education, welfare and healthcare. SEISA Kokusai High School, the core of SEISA’s junior high and high school programs, is a wide area correspondence high school which was established in 1999 as a completely new type of correspondence school, by applying all of the expertise accumulated at SEISA over the years.
SEISA’s education does not specialize for limited needs, but rather offers a wide range of options to meet the needs of every student. Our mission is to create opportunities, supports, environments that are required by the various needs of children. Nowadays terms such as "school refusal", "NEET" and "special needs education" have become more common, however, these are what SEISA has been working on for the past 50 years and has been doing as a matter of course.
