The Buraku is a group comprising two to three million people in Japan whose ancestors performed "unclean" work. As a result their descendants are discriminated to this day. The United Church of Christ in Japan (KYODAN) maintains two Buraku liberation centres (one in Osaka and one in Yasu) which bring attention to their discrimination. Their aim is to overcome discrimination against the Buraku and all minorities in Japan and beyond. The EMS has close ties to the KYODAN and supports their work.
