June 9, 1990. The history of Agathe began with the opening of the first Agat store along Antique Street in Aoyama, Tokyo . This is the trajectory of Agathe, which has always been aware of the changing times and proposed jewelry that is half a step ahead , and has grown while gradually changing its expression. And there was a “brand identity” that has always been protected. Agat has grown as a brand loved by many people . Until now, and from now on.
