In 1997, Masaaki Homma established Mastermind Japan. The activity was suspended with the Spring / Summer 2013 collection. Collection development resumed from the 2017-18 autumn / winter season. The origin of the brand name is "a person who is talented in one thing (mastermind)" + "JAPAN (so that people around the world can judge it as a Japanese brand)", and it is a Japanese original technology and master. Together with the craftsmen who are exposed, it also expresses the desire to make the world aware of Japan's super high quality.
