Fortress Japan (Katakana: フォートレスジャパン) is a Japanese company that operates eikaiwa English conversation schools under brands including Global Trinity （Katakana: グローバルトリニティー）. The Consumer Affairs Agency and the Tokyo metropolitan government shut down the company for six months in February 2010 due to its coercive marketing practices, which included false explanations and harassment—both illegal under Japanese law.
