It was established and opened in 2009 after Osaka Prefectural Habikino High School [ja] and Osaka Prefectural Nishiura High School [ja] were merged.
[1][2] The school name Kaifukan (懐風館) implies respecting the precursors' advice grounded on the history and the ethos of the local area, which is associated with the ancient history and culture of Japan e.g. Furuichi kofungun.
The school emblem was designed after the tachibana and two birds flying abreast.
The freshmen need to take the common curriculum, and the sophomores are required to choose one of the five courses.
[8][9] In 2017 a 18-year-old female student of Kaifukan High School sued the prefecture at Osaka District Court, stating that she suffered mental pain after she had been forced to dye her hair black by the school, seeking the compensation for her damages.
[14][15] In April 2017, the school removed her name from the list of the students arbitrarily and neglected to assign her seating in the classroom.
