Toin Gakuen Schule Deutschland was a Japanese international school in Bad Saulgau, Baden-Württemberg, Germany. It opened in 1992 since many Japanese company employees assigned to work in Germany wanted their children to be prepared for the Japanese school system when they return to Japan. The school had both junior and senior high school sections. Since it was an affiliate of Toin Gakuen, this school was an overseas branch of a Japanese private school, or a Shiritsu zaigai kyoiku shisetsu. The school provided boarding facilities for its students.
