Kikokushijo (帰国子女, lit. "returnee children") and kaigaishijo (海外子女, lit. "overseas children") are Japanese-language terms referring to the children of Japanese expatriates who take part of their education outside Japan. The former term is used to refer to children who have returned to Japan, while the latter refers to such children while they are still overseas. They are referred to in English variously as "sojourn children" or "returnees".[1][2] The term "third culture kids" is used by other countries.[3]
