From the announcement:
Fantasy Flight Games is proud to announce Age of War, a fast-paced dice game for two to six players, set in feudal Japan and created by world-acclaimed game designer Reiner Knizia.
In this game, you and your fellow players take on the roles of rival daimyos, competing to vanquish your opponents and unite all of Japan under one banner. To unite the clans, you must conquer their castles and secure their loyalty, but the other daimyos are mustering armies as well. Will you gain renown with every victory, or become just another forgotten warlord? Find out in Age of War!
