The Lycée Seijo d'Alsace (アルザス成城学園, Aruzasu Seijō Gakuen) was a Japanese boarding high school in Kientzheim (now a part of Kaysersberg-Vignoble), Haut-Rhin,[1] in the Alsace region of France, near Colmar.

[4] The director of the Alsace Development Agency, Andre Klein,[5] received contacts from several Japanese educational institutions after he had asked a Nihon Keizai Shimbun reporter to write an article about a possible site for an overseas Japanese boarding school: a former convent in Kientzheim.

[6] During the school's lifetime, according to the Western Society for French History, the "core" of the student body consisted of children of executives working for offices of Japanese multinational companies such as Sharp Corporation and Sony in the Alsace region.

[10] Other students' families lived in other places including Germany, Italy, the Soviet Union, other areas in Europe, Africa,[4] and Australia.

[4] Karl Schoenberger of the Los Angeles Times wrote that the Seijo students "on the whole" were "isolated" at the school even though during athletic meetings they had some interaction with French children.
