This workshop is an annual series starting in 1998 to provide a forum for discussing all important issues in computational condensed matter physics and materials science. This year we celebrate the 10th anniversary of the workshop in Hiroshima. The principal purpose of the workshop is to offer an opportunity for exchanging ideas and enjoying in-depth discussion both in the methodology in computational physics and chemistry and in its application to materials. Majority of the participants are expected to come from asian countries and regions, as is expected from the workshop title. Yet scientists from other areas are also very welcome to join us.
