A team of historians and computer specialists is developing educational software on Japanese history, focusing on the Aizu region. We are using hypertext and hypermedia to promote free form exploration of text and audiovisual materials, including film and animation. Our goal is to develop multimedia software which encourages original exploration of the available data by students. A partial version is available at: http://www.u-aizu.ac.jp/janet-g/ah/hdr.html.
